  • A doomsday-level returnee devours calamities Chapter 111

    [310 years have passed.]

    A high school girl in her late teens, dressed in a school uniform, stared blankly into the air.

    “Where is this…?”

    Her friend beside her shouted.

    “Hey! Oh Haeyoung! What are you doing standing there? Why are you suddenly spacing out? Aren’t you going to school?”

    “……”

    “Oh Haeyoung! Can’t you hear me? You’re going to be late! Late!”

    Only then did Haeyoung snap out of it.

    “Why was I just standing here like this?”

    “Did you eat something weird this morning? You’re acting strange all of a sudden. Are you sick?”

    “No, it’s not that… It just feels weird somehow. This isn’t a dream, right?”

    At that, her friend pinched Oh Haeyoung’s cheek.

    “Ahhhhh! It hurts! It hurts! I said it hurts!”

    Her friend grinned as she looked at Ha-young’s cheek, now swollen and red.

    “See? It’s not a dream, right? So stop talking nonsense and let’s go already. The student council member is on duty at the school gate today. If we’re even a little late, we’re screwed. Seriously, what kind of era is this? Why do they still allow corporal punishment? Right?”

    Grabbing her friend’s hand, Haeyoung ran with all her might. The weather was exceptionally nice. Looking up at the clear blue sky refreshed her mind, and the cool breeze carried the pleasant scent of flowers.

    “……”

    As she glanced around, she noticed bright yellow flowers in full bloom.

    Spring had already arrived.

    When they reached the school gate, pink cherry blossoms fluttered in all directions. Mesmerized by the breathtaking sight, she stood still for a moment before hastily rushing through the gate.

    “Be on time from now on!”

    “Yes!”

    She barely made it in time. Thinking back, the bus was even three minutes late this morning, but thanks to the driver’s kindness, she managed to catch it.

    Overall, it felt like a lucky day.

    Her mood brightened.

    For some reason, she had felt dazed earlier, but now she couldn’t even remember why. She just felt good.

    As she stepped into the classroom, her classmates greeted her warmly.

    “Haeyoung! You changed your hair! It looks pretty!”

    “Oh Haeyoung! Let’s arm wrestle!”

    “Hey, I’m first today. It’s my turn!”

    Boys and girls alike swarmed around her. Oh Haeyoung was well-loved among her friends.

    Class started, and the teacher walked in.

    “Oh Haeyoung, come solve this problem.”

    Math usually made her shudder, but today, her mind was unusually sharp.

    “Correct!”

    Being praised by the teacher lifted her spirits even more.

    Maybe it really was a lucky day.

    Lunchtime arrived.

    She headed to the cafeteria with her friends, chatting about various everyday topics as they ate. Laughter never ceased.

    “Do you want to watch a movie this weekend?”

    “Oh, sorry. I have a date with my boyfriend.”

    “Not you. Haeyoung, there’s a new horror movie coming out. Let’s go watch it! You love horror movies! In the U.S., people apparently ran out of the theater crying!”

    “Haha. That bad? Sure, I’ll keep my schedule open for the weekend. I feel like watching a movie for the first time in a while.”

    “Hehe, really? Somehow, horror movies aren’t scary when I watch them with you, Haeyoung!”

    “That’s because she’s so cheerful.”

    After finishing their meal, they headed to the school store. The store was as popular as an idol, so they had to wait in a long line.

    The students ahead of her finished paying, and soon it was Oh Ha-young’s turn.

    But her favourite pizza bread was already sold out.

    Just then, the boy in front of her handed her the pizza bread he was holding. His face was flushed red, as if embarrassed.

    “Here, you take it.”

    “Really? I can really have it?”

    “Yeah.”

    “Hehe. Thanks! I’ll enjoy it!”

    The boy who gave her the pizza bread quickly walked away.

    Haeyoung’s friends, who had been watching the scene unfold, whistled and teased her.

    “Ohh~ Oh Haeyoung, look at you~”

    “The cutest, sexiest girl in town, Oh Haeyoung!”

    “Oh Haeyoung! Oh Haeyoung! Oh Haeyoung!”

    Even as her friends teased her, Haeyoung just grinned happily.

    It was an ordinary day, yet it felt extra special.

    Thinking that this kind of daily life would last forever, she couldn’t help but smile.

    Lunchtime ended, and the next class began.

    [320 years have passed.]

    Nodding off, Haeyoung suddenly jerked awake.

    ‘What was that sound just now? I swear I heard a voice… Was it just my imagination?’

    Since she had just dozed off, she thought she might have confused it with a dream.

    ‘Ugh. I should cut back on gaming.’

    She patted her cheeks with both hands to wake up and looked out the window.

    Students were playing soccer on the field.

    And then…

    [Inboiganungeongosipjeoeunjugeotdamanboneungeoseuljongneaneulbeotggueogonalsipsoeopseohandadayeongggumwonttaenhankkumgueulggureonggotongwonihaloneuntteolgeoseulboeogojilsipgeoseuli…]

    Red letters floated in the sky.

    A noise, like static interference, buzzed in her ears, and her vision distorted.

    The clear sky had turned blood-red before she knew it, and what she thought were clouds had transformed into massive eyeballs, with pink, organ-like masses dangling from them.

    Terrified by the grotesque sight, Oh Haeyoung shot up and screamed.

    “Kyaaahhh!”

    All eyes in the classroom turned toward her.

    “Haeyoung?”

    “Oh Haeyoung, what’s wrong?”

    Despite the concerned voices of her classmates and teacher, Oh Haeyoung said nothing, staring outside.

    She closed her eyes, took a deep breath, and looked out the window again.

    As if nothing had happened, the sky was clear and blue.

    Haeyoung let out a shaky breath of relief.

    Cold sweat dripped down her back, soaking her uniform.

    “Haa… Haa…”

    The teacher, noticing Oh Haeyoung’s pale complexion, asked with concern, “Oh Haeyoung, are you okay? If you’re not feeling well, do you want to go to the nurse’s office?”

    “…I’m fine. I’m sorry for causing a disturbance.”

    As Haeyoung sat back down, her deskmate cautiously asked, “Did you have a nightmare?”

    “I think so…”

    “What kind of dream was it that made you react like that? Was it really scary?”

    “I suddenly heard a strange voice, then red letters appeared in front of me, and the sky… It was filled with things that looked like intestines hanging all over… It was truly… a horrific dream.”

    Upon hearing those words, her deskmate’s lips stretched into an unnatural grin, reaching all the way to their ears, and a chilling voice flowed out.

    “That wasn’t a dream.”

    “…”

    Haeyoung squeezed her eyes shut. Her heart pounded wildly, and her hands trembled uncontrollably.

    ‘What is this? Why am I seeing these things?’

    Her mind was in complete disarray, unable to make sense of anything. A lifelong believer, she instinctively began to recite the Lord’s Prayer.

    ‘Our Father, who art in heaven, hallowed be thy name. Thy kingdom come, thy will be done, on earth as it is in heaven. Give us this day our daily bread, and forgive us our trespasses, as we forgive those who trespass against us…’

    When she opened her eyes again, her deskmate was looking at her with concern.

    “Haeyoung, are you really feeling okay?”

    “Just now… I could have sworn…”

    “Hm?”

    “…Never mind. I must be feeling off because I didn’t sleep well.”

    “But why didn’t you finish the Lord’s Prayer?”

    “…”

    Her deskmate’s eyes turned completely black, and then, in an unnervingly rapid tone, they began to recite:

    “…Who trespass against us forgive we as, trespasses our forgive and, bread daily our day this us give. Heaven in is as earth on done be will thy, come kingdom thy, name thy be hallowed, heaven in art who Father our…”

    They had repeated the exact Lord’s Prayer—backward.

    As if mocking her.

    Overcome with sheer terror, Oh Haeyoung collapsed, unconscious.


    [330 years have passed.]


    [340 years have passed.]

    When Haeyoung opened her eyes, she looked around.

    ‘The smell of disinfectant…’

    It was the school’s infirmary.

    The school nurse, clad in a white coat, gently asked, “You’re awake?”

    “…Yes.”

    “You must be really exhausted. Studying is important, but your health comes first, understand? Take care of yourself properly. Make sure to take your supplements too. You need to start looking after yourself at your age—otherwise, you’ll regret it when you’re older.”

    “Yes. Thank you.”

    “Alright. You should head out now. I’m about to clock out too.”

    As Haeyoung stepped out of the infirmary, the friend who had walked to school with her that morning was waiting outside.

    “Oh Haeyoung! Are you okay? Do you feel sick anywhere!?”

    “…I’m fine.”

    “You don’t look fine. Let’s go home quickly so you can rest.”

    Haeyoung silently nodded.

    Everything she had seen… It was too vivid to dismiss as just a dream.

    And that made her anxious—what if even her closest friend, Kim Nayoun, suddenly changed? If she witnessed something like that again, she feared she might die from sheer terror.

    Fortunately, the walk home was uneventful. So much so that her earlier worries felt pointless.

    Kim Nayoun, seemingly sensing Haeyoung’s low energy, was even more talkative than usual, trying to lift her spirits.

    “So, when are you finally going to introduce me to your brother!?”

    “My brother is a seminary student.”

    “So what?”

    “What do you mean, so what? You know priests can’t get married, right?”

    “They might not get married, but they can still date! Just set up a meeting for us! I’ll take care of the rest!”

    “What do you mean you’ll take care of it? That’s ridiculous! No way.”

    “Awww, just once? Please? Just one time?”

    As they joked around on their way home, they soon arrived at the apartment complex. Since Kim Nayoun lived in the neighboring building, this was where they parted ways.

    “See you tomorrow!”

    “Bye.”

    Thanks to Nayoun’s silly chatter, Haeyoung’s mood had improved somewhat.

    She was grateful to have such a good friend.

    Stepping into the elevator, she pressed the button for the fourth floor.

    With a ding, the doors slid open.

    A corridor-style, old apartment complex.

    Her home was unit 404.

    Though her family wasn’t particularly wealthy, Haeyoung was content. It was a home she could proudly call warm and loving.

    Money was important, yes—but love was something that money could never buy.

    Her family deeply cared for one another, and thanks to them, she had learned what it meant to love.

    Just being born into such a family felt like a blessing.

    Grabbing the doorknob, Haeyoung called out cheerfully,

    “I’m home!”

    But for some reason…

    There was no response.

    “…”

    All the shoes were in the entryway. That meant everyone was home.

    ‘What’s that smell?’

    A metallic scent came from inside.

    Taking a step forward, Haeyoung froze in place like a stone statue.

    “…”

    The floor, the walls—everything was drenched in blood.

    And in the middle of the living room…

    A man, covered head to toe in crimson, sat grinning at her.

    Her lips quivered as a faint, trembling voice escaped.

    “O…ppa?”

  • A doomsday-level returnee devours calamities Chapter 110

    Crunch. Crunch.

    Han Yugwang walked forward, gripping Shisan Hyulhae in his hand.

    The murderous aura emanating from his entire body was so intense that Taeseong felt as if his whole being was being pierced by needles.

    “Demon King. Why do you still wander the mortal world? How many more lives must you take before you are satisfied?”

    Han Yugwang, born from Lee Taeseong’s memories, seemed to believe that this place was still the real world.

    Perhaps due to the oppressive killing intent, Oh Haeyoung’s face openly displayed her agony.

    “Te… Team Leader! Who is that guy? Is he an entity? Why is he calling you the Demon King?”

    “He seems to be a manifestation from my subconscious.”

    “From your subconscious? Just what kind of trauma did you go through for a monster like that to appear?”

    Hearing her words, Lee Taeseong smirked.

    He had already been curious about how much he had changed compared to his past self.

    And now, the perfect test subject had appeared—one that wouldn’t even die in this place.

    There was no better opportunity to test his skills.

    The same went for Oh Haeyoung.

    “Oh Haeyoung.”

    “Yes?”

    “Give it your all. We can’t die here anyway, so this is the best possible condition for improving your skills.”

    Han Yugwang was, without question, the strongest martial artist on the Eastern Continent.

    A man whose power was so great that, despite being human, he was called a god.

    Just facing an opponent of his caliber would be an invaluable experience for Oh Haeyoung.

    And since they couldn’t die here, this was the perfect opportunity to train for the day they had to face such an enemy in reality.

    The most crucial thing when fighting someone stronger was to not let fear take hold.

    It was human instinct to shrink back when faced with a superior opponent.

    But the moment fear took over, one could no longer wield their full strength.

    And if they couldn’t even use their own power properly, how could they ever hope to win?

    “Now’s your chance to learn how freeing it is to not fear death.”

    “…I-I’ll do my best!”

    Oh Haeyoung regretted those words almost immediately.

    Just because they couldn’t die didn’t mean they couldn’t feel pain.

    Slash!

    She was torn apart before she could even get close.

    She hadn’t even registered Han Yugwang’s sword moving.

    Agonizing pain consumed her entire body, yet she couldn’t even scream before she perished.

    But since this was a mental world, her body was restored in an instant.

    It was a bizarre experience.

    “……”

    Dazed, she watched the battle between the two men.

    Her perception simply wasn’t fast enough to keep up.

    All she could see were streams of crimson light weaving through the air, like a deadly dance of swords.

    Lee Taeseong and Han Yugwang clashed.

    Both wielded Shisan Hyulhae.

    With each exchange, slashes rained in every direction.

    The twin blades, brimming with murderous energy, lunged at each other, trying to devour their opponent.

    Han Yugwang’s every strike shredded Taeseong’s body into pieces.

    But Taeseong took advantage of his regeneration, charging in again and again.

    Even so, the gap was obvious.

    He couldn’t last beyond five exchanges before his body was carved into twenty pieces.

    “Demon King. Is this all the strength you have?”

    “You tell me.”

    No matter how many times he was torn apart—tens, hundreds of times—Lee Taeseong never stopped attacking.

    [6 Years Have Passed.]

    He used every ability at his disposal, but Han Yugwang was like an impenetrable wall.

    Even when Taeseong unleashed forces akin to natural disasters upon him, Han Yugwang repelled everything with a single swing of his sword.

    [7 Years Have Passed.]

    Oh Haeyoung joined the fight this time.

    She lasted less than five seconds before being reduced to a pile of meat.

    She realized that before she could even fight back, she needed to adapt to that absurd speed first.

    Meanwhile, Taeseong endured ten exchanges.

    A satisfying improvement.

    [10 Years Have Passed.]

    Han Yugwang was astonished by Taeseong’s relentless will.

    ‘That man is a demon! He won’t stop until my body is torn to shreds!’

    [20 Years Have Passed.]

    Oh Haeyoung continued to observe the battle.

    She hadn’t wasted her time—she was slowly starting to grasp their movements.

    She couldn’t see them perfectly, but she could now distinguish between attack and defense.

    “…Team Leader. You’re a real monster.”

    She admired at his rate of growth.

    Having only recently been promoted to Delta-class, she couldn’t even begin to imagine the strength of Alpha-class entities or administrators.

    But she was sure of one thing—those two were far beyond that level.

    [30 Years Have Passed.]

    Lee Taeseong could now exchange over fifty blows with Han Yugwang while maintaining composure.

    His martial arts had improved, but his regeneration was the biggest factor.

    ‘How strong was I back then, exactly? If I could take down monsters like him…’

    He couldn’t even fathom what level he had once reached.

    His past self had struggled against Han Yugwang, but in the end, he had won.

    He had killed him and devoured his core.

    Yet even after fighting Han Yugwang for over thirty years, he still couldn’t land a single cut on him.

    Only now had he reached the stage where he could keep up.

    [40 Years Have Passed.]
    [50 Years Have Passed.]
    [60 Years Have Passed.]
    .
    .
    .
    [100 Years Have Passed.]

    “…I finally understand. This place is an illusion.”

    Slash!

    The blood-soaked blade of Shisan Hyulhae sliced through Han Yugwang’s head.

    Thud.

    His severed head fell to the ground, and Taeseong muttered under his breath.

    “Shit. That was disgustingly difficult.”

    It had taken a full century to bring him down.

    Now, he fully understood why Han Yugwang had been called one of the Three Gods.

    Even though he had only been a phantom, he was the strongest opponent Taeseong had ever faced.

    And he knew—his victory wasn’t purely due to his own strength.

    Luck had played a part.

    Realizing that this place was nothing more than an illusion, Han Yugwang’s composure wavered, creating an opening. Taeseong seized the chance. If they were to fight again, he honestly couldn’t guarantee victory.

    “Still, there were gains. It was definitely worth coming here.”

    In the meantime, Oh Haeyoung had been training in lightning energy.

    She had made significant progress.

    Now, she could control it as naturally as moving her hands and feet.

    “You’re really relentless, Chief. Aren’t you afraid? Even if you have regeneration and can’t die, the pain is still the same… No matter how many times I get sliced up, I can’t get used to it…”

    “I’m the same. No matter how many times it happens, you never get used to it. But you just endure it. If you keep holding on, and holding on, and holding on, eventually, an opportunity will come.”

    “That’s really admir—”

    Slash!

    The blade, imbued with killing intent, cut through Oh Haeyoung’s neck like tofu, and her head fell to the ground with a thud.

    “—able?”

    Moments later.

    Reformed, Oh Haeyoung instinctively reached for her neck with a shocked expression. Thankfully, it was still attached.

    “Chief! What the hell was that…?”

    Before she could even finish her sentence, Taeseong’s blade came at her again at an astonishing speed. Having just gone through that, she instinctively summoned her lightning energy, barely dodging in time.

    “What the hell! Chief! Have you gone insane from being in here too long?”

    “You know there’s no better way to get stronger than real combat.”

    “No, wait. Stop. Just stop. At least talk— Damn it!”

    Even in the most urgent situations, Oh Hae-young had never cursed before. Yet now, the words flew out of her mouth.

    Of course, her severed head hit the ground again.

    [110 years have passed.]

    It took ten years for Taeseong to stop swinging his sword.

    In that time, Oh Haeyoung had died an uncountable number of times, which had made her significantly more aggressive.
    For example…

    “Ugh, damn it. Taeseong, does bullying someone weaker than you make you happy? Huh? Does it? You keep swinging that sword under the guise of training. I mean, damn it, isn’t there a limit? Or do you have some kind of sick fetish for dismemberment? Does chopping me up get you excited or something?”

    “…….”

    “What? Why are you staying silent? Did you forget how to talk?”

    “…Your language has gotten quite crude.”

    “And whose fault is that? Who the hell do you think is responsible for this, huh? It’s all your damn fault, you son of a—!”

    As Oh Haeyoung threw a fit, lightning crashed down all around them. She had now mastered most of the power within the dragon’s core.

    “It’s time to sleep.”

    “Son of a—! Son of a—! How long are we gonna stay here?! Let me out! I want to go outside, you bastards!!!”

    “Be quiet and sleep.”

    Though the concept of sleep didn’t exist in this place, they had begun resting regularly at some point. Simply closing their eyes. It was their own way of preserving their sanity.

    Though it was nothing more than a imitation, it at least made them feel slightly refreshed. And honestly, that was all that mattered.

    [120 years have passed.]

    They trained together.

    Oh Haeyoung mastered the ability to compress her lightning energy and fire it in a straight line, while Taeseong learned how to push his regeneration to the extreme, reinforcing his physical body.

    [130 years have passed.]

    They talked about everything—how they had lived, what they had gone through, what they liked. With nothing but time, their conversations were endless. They spoke about so much, yet Oh Haeyoung never once mentioned her family. Taeseong assumed it was related to some deep-seated trauma. Meanwhile, Oh Haeyoung learned that Taeseong’s first time was at 17.

    [140 years have passed.]

    They sparred. Oh Haeyoung could now dodge one out of a hundred of Taeseong’s surprise attacks.

    [150 years have passed.]

    They talked again…

    [160 years have passed.]

    They sparred…

    [170 years have passed.]

    ……
    .
    .
    .

    [300 years have passed.]

    Oh Haeyoung’s mind shattered.

  • A doomsday-level returnee devours calamities Chapter 109

    [G-Grade Entity Management Report]

    No. 09249
    Entity Name: Voice of the Mind
    Grade: Gamma (G)
    Upgrades to Beta (B) upon meeting specific conditions.

    Risk Level: 4 (increases to 6 upon meeting specific conditions)
    Classified as an Orange-Grade Risk Entity.

    Information

    This entity is classified as a tool-type entity believed to have crossed over from another dimension. While it undeniably possesses self-awareness, its sole function is that of a tool, and thus, it is not considered a living being.

    When the red switch is pressed, the entity manifests an internal world of the mind. This world provokes the traumas of those inside, showing them various illusions. The pain experienced in this realm is identical to real-life pain, though it has been confirmed that it does not cause physical harm. However, individuals whose minds completely collapse in this world fail to recover even after returning to reality.

    Special Notes

    Administrators who complete assignments involving this entity retain no memories of the experience, with the exception of certain anomalies.

    ⚠️ Caution

    1. Even if you believe you possess an exceptionally strong mind, it is strongly recommended that you carefully reconsider before volunteering for an assignment involving this entity.
    2. The decision is yours alone. The author of this report has personally completed an assignment involving this entity and was promoted to Gamma-grade Administrator as a result. However, keep in mind that mental strength and physical strength do not always correlate. There is a case where a Beta-grade Administrator lost their sanity and returned in a vegetative state after exposure to this entity.

    [Observation Log #118]

    What? 500 years have already passed? I just closed my eyes and opened them again. Come on, don’t joke with me. I swear, I remember everything clearly—nothing happened. We might need to revise the report. Nothing happened. Huh? Wait…

    [Observation Log #120]

    I took a nap, and when I woke up, it was all over. I feel refreshed.

    [Observation Log #121]

    My insomnia is completely cured. If any administrators struggle with insomnia, I highly recommend using this entity.

    [Observation Log #124]

    Don’t believe the ones above me. They’re all liars. My colleague was assigned to this entity and came back unable to recognize their own family. Bastards. If you don’t want to end up brain-dead, never take on an assignment involving this entity. Remember this.

    [Observation Log #128]

    This report was transcribed from the voice recording of an administrator who suffered permanent physical damage after assignment.

    Greed leads to destruction. I volunteered for this entity’s assignment, driven by my desire for strength…When I opened my eyes at the end of it all, I had lost everything. I don’t know what happened to me. I can’t use the bathroom alone, I can’t walk, I can’t even feed myself. The most frustrating part? I don’t even remember what happened to me.

    To the future administrators reading this report, heed my warning. Never take on an assignment with this entity. You will regret it. You will.


    Taeseong finished reading the entity management report and handed it to Oh Haeyoung.

    “Have you read this before?”

    “Yes.”

    “This entity seems even more dangerous than I thought. As stated in the report, raw strength and mental fortitude don’t always correlate. Even a Beta-grade administrator lost their sanity.”

    Haeyoung, who was usually cheerful, now looked completely stiff. With a tense voice, she asked,

    “…Taeseong—no, Team Leader. Will you really be okay? What if something happens to you because of me…?”

    Taeseong answered immediately.

    “There’s no problem.”

    He was being sincere. Taeseong felt no fear toward this entity. In fact, he was eager to enter—it was an enticing challenge.

    To put it simply, this was a 500-year training ground where time didn’t pass in reality, offered with no strings attached. Why would he refuse?

    Based on his fragmented memories, he had already spent over 700 years in similar conditions. Even that was only an estimate based on what he could remember. If he recovered more memories in the future, the actual number would likely far exceed 700 years.

    “Are you afraid?”

    Haeyoung nodded, answering honestly.

    “Yes. I’m really scared. What if… what if I can never return?”

    “I understand. If you’re afraid, you don’t have to force yourself. There are other ways to get stronger.”

    “But… nothing else offers progress as quickly as this.”

    Taeseong asked,

    “Do you have to join Management Team 0?”

    “……”

    “Even if you’re not in my team, you’re still my colleague. I won’t forget how much you’ve helped me. If you’re in trouble, I’ll be there to help you.”

    Haeyoung smiled at his words.

    “I feel the same. Team Leader, and all of my team members, are precious to me. But… if I don’t make it into Management Team 0 this time, I feel like I’ll be stuck forever.”

    “I see.”

    “Yes. I only made it this far—from Epsilon-grade Administrator to now—because I met you, Team Leader. That’s why… I want to stay by your side and continue doing management work with you.”

    “……”

    “I believe that’s directly connected to my goal.”

    Taeseong didn’t know what her ultimate goal was. He could only assume she had personal reasons, but he didn’t pry.

    “Moving forward is your choice. Opportunity may come to everyone, but only those prepared can seize it.”

    “……”

    “Oh Haeyoung. Are you ready?”

    No one knew whether this was an opportunity or a fatal mistake. The choice was hers alone.

    Haeyoung hesitated briefly before answering with a determined expression. It took less than a minute to make a life-changing decision.

    “Yes. I’ll do it.”

    “Good.”

    Both Taeseong and Haeyoung turned to the red switch on the desk.

    Once they pressed it, there would be no turning back.

    They exchanged a brief glance before reaching forward together.

    Click!

    “……”

    “……”

    Nothing happened.

    “Is the entity malfunctioning?”

    “Wait… don’t tell me 500 years already passed?”

    Just as those thoughts crossed their minds—

    The world was swallowed by darkness.

    And then, a strange voice, neither male nor female, echoed inside their heads.

    [Species ‘Human’, Species ‘Unknown’ confirmed.]

    [Adjusting difficulty settings.]

    [Adjustment denied.]

    [Welcome, new challengers.]


    [Time Limit: 700 Years]

    Oh Haeyoung opened her eyes in a space shrouded in darkness.

    “700 years…? The containment report clearly stated 500 years… Why?”

    All around her was nothing but darkness. No matter how she turned her head, she saw nothing.

    There was nothing here.

    A vast, empty space.

    A void filled only with darkness.

    The moment she recognized this, chills ran down her spine. She felt like she had been left alone in the middle of an endless ocean.

    “…….”

    The thought of having to endure this place for 700 years sent waves of fear through her.

    Now she understood why the administrators who had taken on this entity’s management had suffered mental collapse.

    “Assistant Manager Oh Haeyoung.”

    Lee Taeseong’s voice echoed from within the darkness. But she couldn’t pinpoint where it was coming from.

    It seemed to come from her left—then from her right. From above—then from below.

    In a space where even her sense of direction was absent, Oh Haeyoung suddenly feared she might simply disappear.

    That she would be swallowed by the darkness and forgotten—that even the existence of “Oh Haeyoung” would be erased.

    “Administrator Oh Haeyoung.”

    “Team Leader!”

    No response came.

    She couldn’t tell if she was lying down or standing, if she was facing forward or to the side—nothing made sense.

    “Oh Haeyoung.”

    Only Lee Taeseong’s voice echoed emptily through the void.

    At that moment—

    Fwoosh!

    Brilliant blue flames ignited all around, illuminating Oh Haeyoung’s vision, which had been consumed by darkness.

    “There you are.”

    “Team Leader!”

    Before she knew it, she had thrown herself into Lee Taeseong’s arms. She didn’t know how much time had passed, but to her, it had felt like an eternity.

    [1 Year Has Passed.]

    Lee Taeseong spoke calmly.

    “One year has already gone by.”

    “…One year? Are you saying we found each other here after an entire year?”

    “That seems to be the case.”

    Her sense of time was completely shattered.

    To Lee Taeseong, it hadn’t even felt like a full day.

    But to Oh Haeyoung, it felt like at least 50 years had passed.

    “Did you train in the meantime?”

    Oh Haeyoung looked at him in disbelief.

    “Train?”

    Lee Taeseong’s expression was one of pure matter-of-factness.

    “Of course. Wasn’t that the reason we came here—to get stronger?”

    “Wait… You’re telling me you’ve been training this entire time?”

    Lee Taeseong nodded.

    “Obviously.”

    Even while searching this vast space for Oh Haeyoung, he had taken every opportunity to train.

    That was the purpose of entering this place, after all—to use his time as efficiently as possible.

    “Hahaha! That’s so like you, Team Leader!”

    Finally, some of her tension seemed to ease, and she laughed.

    “You never know what might come at us, so it’s best to keep training while we’re still in our right minds. I’ll be watching, so summon the power you received from the Guardian Dragon.”

    “Yes!”

    Oh Haeyoung’s eyes turned golden.

    Drawing upon the energy within her, golden lightning flared across her body.

    Crackle. Crackle.

    Lightning flickered wildly around her, like a shimmering mirage. The fact that it wasn’t fully controlled was clear.

    Lee Taeseong observed and offered his advice.

    “Start by gathering the energy in one place.”

    “Got it!”

    Oh Haeyoung focused on condensing the lightning at her fingertips. It wasn’t as easy as she thought, but time was something they had in abundance.

    Even as she failed repeatedly, she refused to give up, trying again and again.

    While Oh Haeyoung trained, Lee Taeseong sat cross-legged, lost in thought.

    Drawing from his memories, he deeply contemplated the sword techniques he had come to understand.

    Sometimes, he would rise and swing his sword.

    Other times, he moved his hands as though they were blades.

    “So, this is how it’s done…”

    .
    .
    .

    [5 Years Have Passed.]

    At last, Oh Haeyoung succeeded in controlling the lightning across her entire body.

    “Team Leader! I did it! I finally managed it!”

    “Then let’s move on to the next stage—”

    Lee Taeseong abruptly stopped mid-sentence and turned his head.

    From deep within the darkness, a figure approached.

    A man, steadily drawing closer.

    “Dark Lord… Why are you here?”

    One of the Three Gods of the Eastern Continent.

    A man who held the title of the Sole God.

    Heavenly Demon-Slaying Blade—Han Yugwang.

    The one called the Greatest Blade Under Heaven walked forward, his piercing eyes gleaming coldly.

  • A doomsday-level returnee devours calamities Chapter 108

    Taeseong, who was carefully observing Park Ilhwan on the TV, soon realized what it was.

    ‘A fake.’

    He wasn’t sure if it was a doll, an android, or a doppelganger, but one thing was clear—it was an imitation of Park Ilhwan.

    How did he know? It was simple.

    Because Taeseong couldn’t see the crystal.

    Throughout their time together, he had always seen the crystal embedded in Park Ilhwan’s forehead. He had never bothered to touch it, simply because he never needed to consume it.

    To Taeseong, Park Ilhwan was nothing more than a worm, not even worth feeling hunger for.

    ‘Does he think there’s no need to personally expose his son’s death?’

    Whether it was to prevent stock prices from crashing or for some other reason, it was undoubtedly a cold-blooded decision.

    “Time to go if you’re done eating, oppa.”

    “Yeah.”

    Finishing his preparations for work, Taeseong stood up and left with Sooah, heading toward the tree.

    Various employees from different departments greeted him as they passed through the corridor.

    “Good morning, Manager Lee Taeseong.”

    “Nice to see you, Manager Lee Taeseong!”

    “If you ever have the chance, please visit our Management Team 2 sometime! It would be an honour to work with you!”

    In the past, their gazes had been mixed with awe and curiosity, but lately, more and more people were looking at him with genuine respect. Of course, a few held jealousy and envy in their eyes, but none openly expressed it.

    Before they knew it, Sooah and Taeseong had arrived at the entrance to Management Team 4’s office. Just as Sooah was about to enter, Taeseong started nagging. From his perspective, she was like a child standing too close to the water’s edge.

    “When handling Delta-grade entities, don’t go in alone. Always go in as a group. Stick to the safer ones whenever possible. I know you want to get stronger, but don’t rush it. Your top priority is always safety. Never forget that, Sooah.”

    “I got it, I got it. Oh, by the way, Mangtae Harabeom and the Hong Kong Granny told me to say hi to you. And Eight-footed Ghost has been making a fuss about wanting to see you too. You should stop by sometime. After all, she came all the way from Japan just for you… It feels bad that you haven’t even seen her once. Even I feel guilty just watching.”

    “…Alright.”

    After returning to the Korea branch, Sooah had been working as part of Management Team 4. Everyone—Lee Eunha, Sooah, Taesan, Go Young-hee, and Oh Haeyoung—were doing their best to become stronger. It was all in preparation for joining Management Team 0, which Taeseong was set to lead.

    “And you, oppa, take care of yourself! Just because you can regenerate doesn’t mean you should be reckless! Pain still hurts, you know! See you later!”

    “Yeah. Take care.”

    After seeing Sooah off, Taeseong headed straight for the branch director’s office. By now, walking there felt natural to him.

    At the elevator, Secretary Chae Yumin, who worked for Park Woo-man, was waiting. Upon spotting Taeseong, she gave him a silent bow.

    “Follow me.”

    “Yes.”

    Under her guidance, he arrived at the branch director’s office. Park Woo-man, who had been sitting at his desk, stood up and moved to the sofa, handing Taeseong a cup of instant coffee and a cigarette.

    The two men lit their cigarettes in silence, sipping coffee as smoke curled between them.

    “……”

    “……”

    It was Park Woo-man who broke the silence first.

    “Taeseong.”

    He wasn’t addressing him as ‘Manager Lee Taeseong,’ as he usually did. Taeseong replied calmly.

    “Yes, Director.”

    “I told you to keep things within reason, but you went and caused a massive incident.”

    “…Things just turned out that way.”

    “Just turned out that way? That’s hard to believe… Killing or crippling South Korea’s high-ranking officials wasn’t enough, so you went ahead and killed the second son of Ilseong Group—and even gifted his head to their chairman?”

    Taeseong took a sip of his coffee, his voice low.

    “That’s right.”

    With a troubled expression, Park Woo-man rubbed his bare forehead.

    “And you completely wrecked their research facility? Do you even realize how much that thing was worth?”

    “Well… things just turned out that way.”

    “You little—”

    Sizzle.

    The end of Park Woo-man’s cigarette burned away with a faint hiss. He exhaled a long breath of smoke before stubbing it out in the ashtray. Then, he spoke quietly.

    “The entity Harin introduced—was that your doing?”

    “Yes. I gave her my business card.”

    “I’ve never seen an entity walk in on its own before.”

    “Well, we would’ve had to capture him eventually anyway. Think of it as one less job to do.”

    “You sure talk smooth.”

    “What happened to her?”

    “For now, she’s in temporary isolation. She seems to be a pretty strong entity, so we’ll process her according to protocol. If she shows promise, we might use her as a manager.”

    “I see.”

    Park Woo-man wore a troubled expression. Taeseong knew the reason for that—most of his concerns revolved around him.

    “The relationship between Ilseong and us is both simple and complicated. In the past, things were different, but now, we can’t afford to take them lightly. At least, that’s the stance of the Korea branch.”

    “…I understand.”

    Park Woo-man looked into Taeseong’s eyes.

    Though his crimson pupils remained as calm as a still lake, Park Woo-man knew that within them, a raging lava flowed beneath the surface.

    And if that lava were to erupt, even he wouldn’t be able to contain it.

    “You have no intention of stopping here, do you?”

    “If I were going to stop, I wouldn’t have started in the first place.”

    Delivering Park Ilhwan’s severed head to Park Ilwang, the chairman of Ilseong Group, had been a declaration of war.

    A message:

    Prepare yourself.

    Next time, I’m coming for your head.

    “…Do you really have to go that far? The one responsible for your revenge is already dead.”

    “The chairman is just as guilty. Park Ilhwan may have been the one who wielded the sword that killed my parents, but it was the chairman who put that sword in his hands. Besides, even if I stop, they won’t.”

    Park Woo-man nodded silently. He agreed.

    “I met with Ilseong’s chairman yesterday.”

    “What kind of man is he?”

    After a moment’s hesitation, Park Wooman finally responded.

    “A lunatic with grand ambitions.”

    “……”

    “But he’s an idiot with that much ability.”

    Though he used the word “idiot,” the fact that he acknowledged the man’s abilities meant that even Director Park Woo-man held him in high regard.

    “Taeseong.”

    “Yes.”

    “I know how strong you are. Given some more time, I might not even be able to stand against you.”

    “……”

    Taeseong didn’t bother with false humility. He thought so himself.

    “But Ilseong is not an opponent to be taken lightly. Ranking among the top ten corporations in the world… you know what that means without me spelling it out. The head of such a group has his sights set on you. He’s persistent, and he will press you with every means at his disposal.”

    “Yes.”

    “I can only help you within ‘Tree.’ Don’t act recklessly, believing in your own strength. You may come out unscathed, but if you want to protect those you care about, you need to be even more cautious.”

    His words carried sincerity.

    Coming from someone who wielded karma as his power, they felt even heavier.

    “I’ll keep that in mind.”

    “Good. You can go now.”

    Taeseong rose from his seat and exited the director’s office. Park Woo-man let out a deep sigh as he stared at the spot Taeseong had just vacated.

    He’d finally found someone he liked, only for that person to rampage around like a mad dog, stirring up trouble everywhere.

    Nothing in life ever went smoothly.

    “My head’s going to explode.”

    As he cautiously ran a hand over his remaining hair, Park Woo-man felt a strong hunch that he would soon be swept into an even bigger storm.


    Walking through the corridor after leaving the director’s office, Taeseong spotted a familiar face.

    From a distance, Oh Haeyoung saw him and began jumping up and down, waving enthusiastically.

    “Taeseong—no, Team Leader Lee Taeseong! Hehe, it’s been a while!”

    “What are you doing there, Section Chief Oh Haeyoung?”

    She was standing in front of the isolation chamber containing a Gamma-grade entity.

    “Well, um…”

    Oh Haeyoung had been promoted to Delta-grade in recognition of her contributions during the Japan assignment. But that wasn’t enough. The condition Taeseong had set for her was to reach Gamma-grade. Since her return, a week had already passed, leaving her only three weeks to meet the requirement.

    “I was debating whether or not to take on this entity’s assignment.”

    Taeseong frowned. It didn’t make sense to hesitate over an entity assignment.

    “What entity is it?”

    “The Gamma-grade hazardous entity ‘Voice of the Mind.’”

    “……Voice of the Mind?”

    She had received a dragon’s pearl from the guardian dragon but had yet to fully harness even 10% of its power. As the deadline was nearing, her anxiety grew.

    There wasn’t enough time.

    So she had come up with this idea.

    It was a notoriously dangerous entity among senior managers. Uniquely, it wasn’t a living being.

    Though suspected to have a form of self-awareness, ‘Tree’ classified it as a tool-type entity rather than a life-form.

    Then why was it considered so dangerous? Because of its unique characteristics.

    “Five hundred years?”

    “Yes. That’s what the report says. Anyone trapped inside the mental world created by the ‘Voice of the Mind’ must fight against their subconscious, which intermittently manifests for five hundred years.”

    That was why it had such a fearsome reputation.

    Anyone who entered its domain would be trapped in an artificial world for a staggering five hundred years, battling their own subconscious as it took various forms.

    No one knew when or how these manifestations would appear. Some might go five hundred years without encountering anything, while others might be forced to fight nonstop for the entire duration.

    And the entity’s most terrifying trait?

    Once the assignment was complete, the assigned manager would lose all their memories of the experience.

    “What’s the point, then?”

    “They may lose their memories, but the experiences they gain there remain imprinted on their body. If they can endure it, they grow drastically stronger. There are senior managers who took on this entity and saw dramatic improvement. Of course… there are also cases where things didn’t go so well.”

    No matter how strong-willed a person was, most couldn’t endure five hundred years of psychological torment without their mind shattering.

    Even if they couldn’t remember, a broken mind didn’t recover.

    However, for those who survived, the rewards could be immense.

    They would either come out as an empty husk or immeasurably stronger.

    It was truly a double-edged sword.

    Understanding the situation, Taeseong gave a slight nod before waling forward and pushing open the isolation chamber door.

    “……Team Leader?”

    Haeyoung looked at him anxiously, but Taeseong grabbed her arm and pulled her inside.

    “Don’t be afraid. I’ll go with you.”

  • A doomsday-level returnee devours calamities Chapter 107

    The Head of Ilseong Group, Park Ilwang.

    A strange box, crafted from a special material, was placed in front of his residence. When a security guard checked its contents, he immediately called for the chief of security. It was beyond his authority to decide what to do.

    The security chief, who arrived with an irritated expression, fell silent for a long time after seeing what was inside. However, no matter how much he thought about it, the moment he laid eyes on the contents, the answer was already decided.

    After much deliberation, the security chief picked up the unidentified box and made his way to the room of Ilseong Group’s leader, Park Ilwang.

    Knocking cautiously, he spoke with the utmost politeness.

    Knock, knock.

    “Chairman, this is Chief of Security Ha Seung-won. May I enter?”

    Though this wasn’t his first time here, he couldn’t help but feel tense every visit. This was the leader of Ilseong Group—the core of this country’s power.

    Ilseong was the pillar of South Korea. And Park Ilwang was Ilseong itself.

    “Come in.”

    Opening the door, Ha Seung-won stepped inside and bowed at a ninety-degree angle.

    “Good day, Chairman.”

    “Skip the greetings.”

    The man seated at the desk looked, at most, in his mid-forties. Yet, his voice bore the weight of a life filled with experiences.

    His name was Park Ilwang. A true giant, responsible for the fate of South Korea.

    His broad shoulders, thick eyebrows, sharp nose, and piercing gaze gave him the formidable appearance of a tiger.

    His eyes locked onto Ha Seung-won.

    Despite being a towering figure himself—standing at 2.2 meters with an imposing physique honed by years as a mercenary—Ha Seung-won flinched instinctively under Park Ilwang’s gaze. It was an automatic, primal response.

    “That box—is that why you’re here?”

    “…Yes, sir.”

    Park Ilwang gestured with his hand.

    It meant, bring it to me.

    Ha Seung-won, tense, handed over the box. With hands as large as pot lids, Park Ilwang opened it.

    “……”

    At that moment—

    Ha Seung-won instinctively shut his eyes.

    Not because he didn’t want to see what was inside, but because he didn’t want to meet the gaze of the man before him.

    It was a reaction born from primal fear.

    However, he couldn’t keep his eyes closed forever. Slowly, he cracked them open and peeked ahead.

    Park Ilwang’s lips curved into a smile.

    “Hahaha!”

    The sight sent an even deeper chill down Ha Seung-won’s spine.

    And for good reason.

    Inside the box was nothing but the severed head of his second son, Park Ilhwan.

    ‘He’s… laughing? After seeing his son’s severed head?’

    Only Park Ilhwan’s head lay inside, its cut surface continuously flickering with blue flames.

    “Chief Ha.”

    “…Yes, sir.”

    “This is my son’s head, isn’t it?”

    At that moment, Ha Seung-won racked his brain for the best possible answer.

    Yet, no matter how much he thought, no suitable response came to mind.

    So he simply told the truth.

    “Yes, sir.”

    Upon hearing that, Park Ilwang burst into even louder laughter.

    His voice was so powerful that everything in the room—furniture, decorations, even the walls—began to crack and shatter.

    “Hahahaha!”

    Ha Seung-won, now wrapped in a protective aura, stood frozen like a stone statue.

    Moving recklessly in this moment would be a death sentence.

    “…Interesting. How very interesting.”

    “……”

    “Seung-won.”

    “Yes, sir.”

    “Prepare the car.”

    “Where should I take you, sir?”

    “I need to visit an old raccoon I haven’t seen in a while.”


    Meanwhile, in Seoul.

    Park Woo-man, accompanied by his Beta-ranked aide, was heading toward a traditional Korean restaurant.

    Stepping out of the car, he grimaced before entering the establishment.

    “Wait here.”

    “Yes, sir.”

    Creak.

    Park Woo-man opened the door and took a seat.

    Across from him sat Park Ilwang, a man whose fierce aura resembled that of a tiger.

    “It’s been a while.”

    “Yes, it has.”

    This was a meeting between the Head of Ilseong Group and the Director of Tree’s Korea Branch.

    They exchanged formal greetings before silently picking up their glasses.

    Without clinking them together, each drank on their own.

    No words were spoken as they downed five consecutive shots.

    Then, Park Woo-man finally broke the silence.

    “You must be quite free these days, Chairman of Ilseong.”

    “Free? Hah… The man who oversees the world’s economy being told he’s free? That’s not even funny. I suppose your senses have dulled with age.”

    “Is that so?”

    Park Woo-man poured himself another drink and downed it. Then, he met Park Ilwang’s gaze.

    “Let’s get to the point.”

    Park Ilwang smirked.

    “Hand over Administrator Lee Taeseong.”

    Park Woo-man slowly ran a hand over his bald head before shaking his head.

    “I can’t do that.”

    “That man killed my son. And he didn’t stop there—he deliberately sent his head to mock me. And yet… you expect me to tolerate it?”

    “…I’ll have a word with him about that.”

    Park Ilwang let out a hollow laugh at those words.

    A murderous aura flared in his eyes.

    “You’re going to reason with him? That’s it?”

    Park Woo-man responded firmly.

    “Handing him over is impossible.”

    “And why is that?”

    “He’s been designated as a candidate for the next branch director.”

    Hearing that, Park Ilwang muttered in disbelief.

    “A manager named Lee Taeseong is a candidate for the Korean branch director?”

    “That’s correct.”

    Their gazes clashed.

    Neither spoke, but they understood each other’s thoughts perfectly.

    “So, it’s not a lie.”

    “Why would I need to lie? What am I afraid of?”

    Park Ilwang’s expression hardened at those words.

    That last remark was particularly irittating.

    “…You’ve always been like this. Living off Ilseong’s money while acting as if you’re something more.”

    “And isn’t that because we actually are something more? Chairman, whether young or old, you’ve always lacked self-awareness.”

    “Perhaps it’s your branch that lacks self-awareness, not Ilseong.”

    Park Woo-man scoffed.

    “Chairman. Oh, our great chairman. I understand you have an inferiority complex, but you should pick your battles. The Tree Korean branch existed long before your company even started running convenience stores. Do you really think all of this growth was purely your doing?”

    Park Ilwang reacted similarly.

    “Fine. You’re not wrong. I won’t deny that Ilseong benefited from your help. But you’re mistaken about one thing. It wasn’t just ‘us’ receiving help—we helped ‘each other.’ We were business partners, not a master-servant relationship. So why do you keep crossing the line?”

    “…”

    “Mr. Park Wooman, whose head is completely bald?”

    “C-crossing the line, huh…”

    “Branch director. Do you really think Ilseong is tied solely to the Tree’s Korean branch? Our headquarters may be in Korea, but Ilseong’s main base is in the U.S. The U.S. Can you handle that?”

    Park Woo-man silently stared at the man before him.

    Even before taking his position as Ilseong’s leader, he had shown hostility toward Tree.

    From his father’s and grandfather’s generation, he had despised bowing his head to Tree.

    So, when he became chairman, he rapidly expanded Ilseong through exceptional skill and charisma, to the point that…

    ‘It became one of the top ten mega corporation in the world. A corporation powerful enough to stand its ground against us.’

    Park Woo-man spoke.

    “You talk as if you’ve actually met the U.S. branch director. But you haven’t even seen his nose, let alone his face, have you?”

    “…”

    “What? Did I hit the mark?”

    Park Ilwang asked confidently.

    “Do you really think I haven’t met him?”

    “Yes. I’m certain.”

    “That’s why you’re doomed to fail.”

    “Sure, sure. Keep bluffing.”

    Having actually met the U.S. branch director, Park Woo-man was convinced.

    No matter how powerful Ilseong’s chairman was, he would never be able to meet that man.

    And yet, why did he look so confident?

    The Park Ilwang he knew was someone who displayed his emotions easily.

    That made it all the more puzzling.

    His face radiated certainty and confidence.

    It kept raising more questions.

    ‘No way…? Did he actually meet him? No. That’s impossible. It can’t be…’

    Park Ilwang was the first to rise from his seat.

    “You’re still as unreasonable as ever.”

    “If you keep running your mouth, you won’t live long, Chairman.”

    “If you’re so confident, why don’t you kill me right here and now?”

    Park Woo-man clicked his tongue in exasperation.

    “Tch. Seriously.”

    Ignoring him, Park Ilwang opened the door.

    Before leaving, he added one last remark.

    “Branch director. I will handle Manager Lee Taeseong in my own way.”

    Rattle!

    Clack.

    The door shut.

    “That son of a bitch… I can’t even kill him for real.”

    —Should I go kill him now?

    “Forget it. He’s not someone you can kill just because you want to.”

    —Understood.

    Staring at the dining table for a moment, Park Woo-man picked up his chopsticks and began eating again.

    “Showing off just because he has money. What a dumbass.”

    With delicious food and alcohol still left, he grinned, remembering the arrogant fool who had just stormed out.

    “…Money really is nice.”

    As he picked up a piece of sashimi, Park Woo-man thought about Lee Taeseong.

    He had told him he’d let it slide as long as he kept things reasonable, but he never expected him to go this far.

    Not only had he killed Ilseong’s second son, but he had also gifted the severed head to the father!

    “Hahaha! That lunatic Lee Taeseong. That absolute madman. That total maniac.”


    The next morning.

    After waking up, Taeseong casually ate breakfast while watching TV.

    “…”

    “Oppa, what’s wrong?”

    Thinking he was still half-asleep, Lee Taeseong rubbed his eyes.

    But no matter how much he rubbed them, the man on the screen remained the same.

    For a moment, he doubted his own vision.

    “Sooah, is that guy on TV really Park Ilhwan?”

    “Yeah. Ilseong Group’s second son, Park Ilhwan.”

    Shockingly, the man giving an interview on TV was Park Ilhwan.

    The very same man who should have been dead was now alive and well, speaking before the cameras.

    “…”

    “You’ve been acting weird since earlier. What’s going on?”

    Lee Taeseong fell into deep thought.

    ‘I definitely killed him. But then… what the hell is this? Could it be…?’

  • A doomsday-level returnee devours calamities Chapter 106

    Lee Taeseong tormented Park Ilhwan the entire way back to Tree.

    Thanks to possessing a fifth-generation nanomachine, Park Ilhwan never actually died despite the relentless torment.

    His vitality was astonishing.

    “Please… stop…”

    After creating a massive crater on an empty plot of land, Taeseong maximized his ability with Pure Flame, manifesting a domain of fire that evoked the image of a superheated hell.

    He threw Ilhwan into it and observed.

    Trapped in an artificially created inferno, endlessly wandering, his figure was nothing short of pitiful.

    Discussions about the most painful kind of agony in the world were quite active, and among them, one was always mentioned—burning pain.

    The agony of flesh being scorched.

    It drove people insane.

    Even the strongest individuals would last less than five minutes before begging to be killed—that was the nature of burning pain.

    However, Park Ilhwan could not die so easily.

    Despite his entire body melting away, he wandered through the hellfire Taeseong had created like a specter possessed by vengeful spirits.

    His mind had already collapsed, and only the primal instinct to survive kept his body moving.

    “Aahh! Aahh! Aahh! Aahh! Aahh! Aahh! Aahh! Aahh! Aahh! Aahh! Aahh! Aahh!”

    He endlessly repeated his cries of pain as he continued climbing the pit.

    The crater wasn’t particularly high, so with enough effort, he felt like he might be able to climb out.

    A sliver of hope that he could escape this place tormented him without end.

    But as long as Lee Taeseong was there, no matter what he did, even if the sky collapsed or the Earth perished, he would never escape.

    Taeseong did not miss a single moment of the scene unfolding before his eyes.

    Even as he witnessed a sight so horrific that any ordinary villain would grimace, his expression remained unchanged.

    Guilt? He felt none.

    Regret? Of course not.

    It must be painful. It must be agonizing.

    But so what?

    This was just an outlet for his rage.

    No matter how much that bastard suffered, no matter how much he despaired, his dead parents would not return.

    So this was a separate matter.

    He was simply unleashing his fury upon him.

    Taeseong was keenly aware of this fact.

    “Ilhwan. The fire play is over. Now, let’s go play in the water.”

    Taeseong pulled Ilhwan from the flames, his face two-thirds melted away.

    A loud hissing sound erupted as scorching heat radiated from Ilhwan’s body, but the freezing energy surging from Taeseong’s own body instantly neutralized it.

    Soon, Ilhwan was restored to his original state, and his hazy eyes met Taeseong’s.

    “…I’m… sorry… It was all… my fault…”

    His speech was slow and slurred, as if his mind had been broken.

    Taeseong smiled.

    Lately, he had been smiling more than ever before.

    “It’s okay, Ilhwan.”

    “Pl…ease… s-stop… I’ll… do whatever… you want… S-so… so please…”

    “You’re talking too much, Ilhwan.”

    Taeseong shoved his hand into Ilhwan’s mouth, grasped his tongue, and yanked it out.

    “@!$@#%#$^”

    Ilhwan convulsed violently, spewing incomprehensible gibberish.

    His eyes rolled back, leaving only the whites visible, and his body trembled as if performing a frantic breakdance.

    Knowing that leaving him like this would only lead to more noise, Taeseong froze him once again.

    Then, like cradling a precious doll, he tucked Ilhwan under his arm and spread his wings while soaring into the sky.

    Whoosh!

    His massive wings flapped powerfully before he came to a halt in midair.

    Then, he melted Ilhwan and tossed him into the middle of the ocean.

    Splash!

    “It’s time for underwater combat, Ilhwan.”

    Of course, he couldn’t allow Ilhwan’s legs to remain intact, so he tore them off and infused fire and ice into the wounds.

    If the nanomachines inside his body could speak, they would have cursed him out with every curse imaginable.

    —You absolute bastard of an owner! Try taking care of this body properly! No matter how many times I heal it, there’s no end to this! You incompetent fool! Why don’t you just drop dead already?!

    As the cool seawater touched his skin, Park Ilhwan regained some clarity and desperately moved his body.

    However, with both legs missing, swimming was far from easy.

    “……!”

    Even the nanomachines seemed exhausted, as the cold infused into his lower body slowly crept upward.

    He struggled, trying to move his gradually stiffening body.

    ‘Damn it… What the hell am I doing here…? How did it come to this…?’

    His lungs filled with water.

    Agony.

    He couldn’t breathe.

    Yes.

    Maybe it would be easier to just die.

    ‘Kill me, you bastard. See you in hell.’

    Just as his consciousness faded, leaving himself to everything—

    “Gasp!”

    Fresh air rushed into his lungs.

    For the first time in a long while, he tasted Earth’s fine dust—no, oxygen—and it was unbelievably refreshing.

    As he was pulled from the water, Taeseong spoke in a low voice.

    “Did you enjoy the swim?”

    Ilhwan spat out a glob of blood-tinged spit toward Taeseong’s face and muttered through clenched teeth.

    “You sick bastard… Just kill me already.”

    But before the spit could even touch Taeseong’s face, it froze mid-air and fell into the ocean as an ice crystal.

    Even after all that torture, Ilhwan still had defiance in his eyes.

    His mental fortitude was truly remarkable.

    “I can’t do that.”

    Before Ilhwan could say anything else, Taeseong threw him back into the sea.

    This time, he removed his arms as well.

    And so, the cycle repeated.

    Taeseong continued the process until Ilhwan’s mouth no longer opened so easily.

    The words he once screamed—”Kill me, you bastard!”—soon turned into “Please, kill me.”

    By the end, he repeated, “I beg you, please kill me,” like a broken record.

    “It’s not time yet, Ilhwan. Stay with me.”

    “……”

    His eyes were open, but they were empty, lifeless like those of a dead fish.

    Just in case, Taeseong ignited Pure flame over Ilhwan’s right eye, putting on a small fireworks display.

    No reaction.

    His limp body was like a corpse, though he was still breathing.

    Taeseong shouted in panic.

    “Ilhwan! No! You can’t die yet! I still have so much to do with you!”

    His voice was filled with a sorrow as if mourning a comrade-in-arms.

    If his allies saw this scene, they would have been horrified.

    He shook him, struck him, did everything he could—but there was no response.

    “Hmm… This won’t do…”

    Clicking his tongue, Taeseong finally pulled out a drop of the divine tear he had once used on Yeo Gilsoo and dripped it into Ilhwan’s mouth.

    It was a waste, but he couldn’t let him die just yet.

    Gulp.

    As the liquid forced its way down his throat, Ilhwan’s dead eyes slowly regained their light.

    And the first thing he saw upon waking was, of course, Lee Taeseong.

    Then, he promptly fainted again.

    “……”


    Tree Korea Branch

    Upon arriving at the dormitory, Lee Taeseong headed straight to the room where Kim Minji was staying.

    As he opened the door and entered, Kim Minji, who had been hanging from the ceiling watching TV, was startled and turned to look at him.

    [L-L-Lee Taeseong!?]

    “You seem to be enjoying yourself.”

    [Haha… I was waiting for you.]

    “You knew I was coming?”

    At his question, Kim Minji pointed at the TV. It was broadcasting the events Lee Taeseong had caused in bold headlines.

    “Serial assaults on politicians and prosecutors… Who is the culprit?”

    “South Korea cheers for a serial killer… Is he a ‘Dark Hero’ or an ‘indiscriminate murderer’?”

    Fortunately, the news of Park Ilhwan, the second son of Ilseong Group, going missing had not been reported.

    “Are they deliberately suppressing the media?”

    Well, it didn’t matter to Taeseong. He had already prepared for all possible outcomes when he started this.

    The thought of Park Woo-man, likely scratching his already balding head in frustration, crossed his mind, but he dismissed it.

    “Here’s your present.”

    Taeseong opened a subspace and pulled out the frozen body of Park Ilhwan. Kim Minji’s eyes widened, and a fierce killing intent erupted from her entire being.

    Of course, it wasn’t enough to pose a threat to Taeseong, so he merely observed her in silence.

    […You really brought him.]

    “Yeah. I was going to deal with him anyway, but I thought of you and brought him along.”

    [Really… Thank you.]

    “No need for thanks. I’m getting my payment in return.”

    [Ah… Right. Even so, thank you.]

    Kim Minji walked over to the kitchen, reached up to the top shelf, and retrieved an old sword, handing it to him.

    [Here. This is an heirloom that’s been passed down in my family for generations.]

    Taeseong accepted it and gave a small nod.

    “I’ll be outside. Do as you wish. Just keep him alive—I still have use for him.”

    [Understood. Really, thank you.]

    “…Enough with the thanks. You might need this.”

    [What is it?]

    “A lie detector. I don’t need to explain how it works, do I?”

    […Thank you.]

    Taeseong tossed Pinocchio onto the floor and left the room. He also made sure to freeze the entire room to contain any noise.

    It was his way of showing consideration.

    Leaning against the wall, Taeseong fell into thought.

    “Does that bastard even know what repentance is?”

    He shook his head.

    No.

    He wouldn’t.

    Taeseong was sure of it.

    Even if Hell were real and Park Ilhwan ended up there, he would never truly repent.

    He might say the words.

    “I’m sorry.” “I was wrong.” “I’ll never do it again.”

    But those wouldn’t be sincere.

    They’d just be empty words spoken to escape pain.

    People like him never change.

    That was the conclusion Taesung had reached after observing him.

    Ilhwan had begged for mercy, pleaded for it to stop, even asked to be killed.

    But never—not once—had he genuinely sought forgiveness for his crimes.

    He wasn’t the type to feel guilt in the first place.

    So, Taeseong didn’t even expect it.

    That wasn’t why he had done all this, anyway.

    How much time had passed?

    Lost in his thoughts, he eventually realized that the room had gone completely silent.

    “……”

    After a moment of hesitation, Taeseong opened the door and stepped inside.

    Kim Minji stood there in a daze, staring at him, blood-red tears streaming down her face without pause.

    Taeseong asked quietly,

    “Is it over?”

    […Yes.]

    Her voice was filled with sorrow, yet there was a hint of relief.

    “What did he say?”

    […He said he killed my mother in a fit of rage. And he killed my father because he kept getting in the way.]

    “A waste of a human being.”

    [A hopeless piece of trash.]

    After a brief silence, Kim Minji carefully spoke.

    […What will you do now?]

    Taeseong answered without hesitation.

    “I’ll kill him.”

    [I see… Then please make it as painful as possible. I don’t care about repentance.]

    “I’ll do my best.”

    [Thank you for everything.]

    With those final words, Kim Minji’s body began to fade away.

    “Take care.”

    […If I see my father, I’ll tell him about you.]

    “Alright.”

    Kim Minji gave a faint smile before disappearing completely, as if she had never been there.

    Taeseong stared at the empty space for a moment before shifting his gaze to the crumpled body of Park Ilhwan on the floor.

    His expression twisted in irritation as he muttered,

    “I told her to keep him alive… She really left nothing but a heartbeat.”

  • A doomsday-level returnee devours calamities Chapter 105

    The astonishment was evident on Taeseong’s face as he looked at Abidos, whose upper body had been severed in two.

    “…Regeneration ability?”

    Vein-like strands stitched together the bisected torso without pause, rapidly restoring it to its original state. Rising to his feet, Abidos spoke with a bewildered expression.

    “What was that sword just now? Was it too fast for my eyes to follow…?”

    His artificial eye could normally track speeds beyond human perception, even predicting attack trajectories and possible movements in real time.

    But just now, his eye had failed to keep up. That had never happened since arriving in this world. Realizing his opponent was no ordinary foe, Abidos retrieved a syringe from his coat and injected it into his arm.

    The drug heightened his nervous system, providing a significant boost—but its toxicity was lethal, meaning he only used it when he was prepared to die.

    However, Abidos had a sixth-generation nanomachine embedded in his body. Thanks to it, he possessed unparalleled regeneration abilities and was unaffected by poisons.

    Abidos vanished.

    Whoosh!

    Less than a second later, his prosthetic hand lunged toward Taeseong’s side with overwhelming speed. Yet, Taeseong easily evaded it and sliced off both of Abidos’s arms.

    Gazing at his severed limbs on the ground, Abidos murmured with curiosity.

    “Astonishing. I don’t think I’ve ever encountered a human of this caliber, even among Awakened ones…”

    His mind rapidly accumulated real-time data on Taeseong. But no matter how many simulations he ran, he could not visualize a scenario where he emerged victorious.

    ‘Even after injecting the stimulant, the gap in skill is still this vast? Just who is this man…?’

    Abidos abandoned the fight.

    He wasn’t the kind of person who foolishly clung to battles he couldn’t win. Raising his remaining arms, he signaled his surrender.

    “You are strong. I now understand that I cannot defeat you. Though I was the one who attacked first… would you spare my life? If you do, I will do anything.”

    Watching from behind, Park Ilhwan shouted in fury.

    “You’re begging for your life? Are you out of your damn mind?! Hey, Abidos! Are you joking right now?! Huh?! Who the hell told you to surrender without the client’s permission?! Stop spouting nonsense and kill that bastard! Kill him now!”

    But Abidos remained unmoved, maintaining his stance of surrender. There was no point in dying before he even had the chance to return home.

    Seeing his lack of intent to fight, Taeseong asked calmly,

    “You’re a Transmigrator too?”

    “I am.”

    “If your goal is to return home, then you chose the wrong partner.”

    “What do you mean?”

    “You didn’t come here with the Tree?”

    Abidos muttered the word.

    “The Tree…”

    The Tree’s administrators had once come looking for him, but Park Ilhwan had dismissed them before any real conversation took place. As a result, Abidos had never spoken directly with them.

    “They did come, but I never had the chance to speak with them properly.”

    “The Tree has other transmigrator like you. People from different worlds. I can’t say the Tree is entirely trustworthy, but if your goal is to return to your original world, you’d have a better chance with them than with that lunatic.”

    “…Thank you.”

    “I’ll make use of your debt later.”

    Abidos nodded.

    Taeseong walked past him, approaching Park Ilhwan.

    As Taeseong slowly advanced, Park Ilhwan stumbled backward, his voice cracking with terror.

    “S-Shit! D-Don’t come any closer! Stay back, you monster!”

    “I told you to hide well. But in the end, I still found you.”

    Taeseong smirked.

    Park Ilhwan trembled. To him, Taeseong no longer seemed human. Everything he had planned, every scheme he had meticulously crafted, had been reduced to nothing by this one man.

    It was something that should have been impossible.

    “Abidos! Abidos! You useless piece of shit! Why are you just standing there?! Kill him! Kill that bastard! Don’t you want to go home?! Don’t you?!”

    His desperate screams echoed in the room.

    But Abidos still showed no intention of fighting. If anything, he seemed to regard Taeseong with growing favor.

    “Park Ilhwan. Are your eyes just for show? Even after witnessing his strength firsthand, you still expect me to fight him? Are you telling me to commit suicide?”

    “I don’t care if you kill yourself or whatever—just protect me! You worthless bastard!”

    Abidos sighed and leaned against the wall, staring at Park Ilhwan with pity.

    Amused by the spectacle, Taeseong spoke.

    “This must be your real body. Judging by how desperately you’re begging for your life.”

    “……”

    “You were running your mouth just a moment ago. What, cat got your tongue?”

    “Listen, you son of a bitch. I admit you’re strong, but you’re still just one guy. If you don’t want to dig your own grave, get on your knees and beg for forgiveness. Do you even understand who you’re dealing with? You’re messing with Ilseong. Ilseong! The pillar of South Korea!”

    Taeseong inwardly chuckled.

    Even in this situation, Park Ilhwan still had the audacity to spew insults. That level of nerve was, at the very least, commendable.

    “Oh, right. You’re the great second son of Ilseong Group.”

    “That’s right! So if you—”

    Slash!

    It happened in an instant.

    Taeseong swung Sisan Hyulhae five times in quick succession.

    Park Ilhwan hadn’t even seen it happen. Even Abidos’s artificial eye could only track three out of the five strikes.

    Blood gushed as Park Ilhwan’s arms were diced into pieces.

    “Gyaaahhhhhh!”

    His agonized screams filled the air.

    Taeseong watched him thrash in pain with an expressionless face.

    “……”

    But then, to his surprise, Park Ilhwan’s arms began regenerating at an alarming speed.

    “You can regenerate too?”

    Park Ilhwan glared at him in silence.

    Abidos, ever observant, explained from behind.

    “It’s nanomachines.”

    “Nanomachines?”

    “I have sixth-generation nanomachines, while that bastard has fifth-generation ones. His can’t regenerate at a molecular level, but they’re still decently functional.”

    “So he has a regeneration ability, after all.”

    “That’s right.”

    Upon hearing those words, Taeseong’s face lit up with a genuine smile.

    “What a relief. Truly a relief.”

    Abidos and Park Ilhwan, witnessing that expression, simultaneously felt an indescribable terror. Chills ran down their spines, and their hair stood on end.

    ‘This is a man I must never make an enemy of.’

    ‘Shit. That lunatic… What the hell is going through his mind…?’

    Taeseong abruptly turned his head toward Abidos and asked,

    “What’s your name?”

    “Problem-solver Abidos.”

    “Does ‘Problem-solver’ count as part of your name? That’s unique.”

    “No, that’s…”

    Abidos, looking dumbfounded, was about to explain but quickly gave up. Taeseong reached into his coat and pulled out a business card, handing it over.

    [Team Leader Choi Harin, Information Team 2]
    HP: 010 – XXXX – XXXX

    “Abidos.”

    “This is…?”

    “If you’re interested, contact this number and say that Manager Taeseong referred you. A little power struggle is fine, but it would be wise not to be too hostile. That place is filled with monsters even worse than me.”

    “…Thanks.”

    Abidos left without another word.

    Now, only Taeseong and Park Ilhwan remained.

    Clatter.

    Taeseong tossed the blood-soaked Sisan Hyulhae onto the floor.

    “…!”

    Park Ilhwan’s eyes widened at the sight. More than confusion, an overwhelming sense of dread washed over him.

    “Why… why would you drop your sword…?”

    “Why do you think?”

    As Taeseong stepped closer, Park Ilhwan instinctively swung his fist.

    Thud.

    Taeseong caught it effortlessly and twisted it in the opposite direction.

    Crunch.

    “ARGHHHH!”

    With a slight increase in pressure, Park Ilhwan’s arm bent like a twisted rag—and was promptly torn off.

    However, thanks to the miraculous regeneration of his fifth-generation nanomachines, it fully restored itself within about three seconds.

    “The technology is impressive. If you have enough money, even abilities like these are within reach, huh? Were the puppets you controlled also enhanced by this?”

    “I-I…”

    Before Park Ilhwan could even stammer out a response, Taeseong ripped off his arm again.

    Then it regenerated.

    He tore it off again.

    Then it regenerated.

    And again.

    Taeseong’s expression remained utterly emotionless. Like a child casually plucking the wings off an insect, he repeated the same action over and over.

    Minutes passed.

    It was a pain unlike anything Park Ilhwan had ever experienced.

    To him, it felt like four agonizing hours had gone by. But in reality, it had been less than ten minutes.

    The empty room echoed with the eerie, wet sounds of human flesh being torn apart—sounds that should never exist.

    The reason Taeseong discarded his sword was simple.

    He wanted to inflict pain in a more primal manner.

    The rage he had built up over time wasn’t even a tenth released yet.

    What Park Ilhwan didn’t realize was that Taeseong was an extremely petty man.

    He never forgot favours or grudges.

    No matter how trivial they were.

    “…P-please… s-stop…”

    “Have you ever stopped just because someone begged you to?”

    Of course, he hadn’t.

    “You wouldn’t have.”

    Taeseong’s crimson eyes burned with intensity.

    The torn flesh where Park Ilhwan’s limbs used to be was now engulfed in azure flames.

    A battle between regeneration and destruction.

    The nanomachines in his body worked tirelessly to restore their host, while Taeseong’s flames ravenously consumed his flesh.

    Time is always relative.

    For Park Ilhwan, time had effectively stopped.

    He was trapped in an endless cycle of pain, suffering through an eternity of torment.

    But what he failed to realize was that his true agony was only just beginning.

    As his mind crumbled under the unbearable pain, Taeseong’s voice rang clear in his ears.

    No matter how much he suffered, that voice remained sharp, precise.

    “You have no idea… how lucky you are.”

    “…”

    “That your body contains nanomachines.”

    “…”

    “Because it means… I can make you suffer endlessly.”

    Park Ilhwan finally lost consciousness.

    Taeseong encased him in ice, then opened a dimensional rift and tossed him inside.

    Within that void, Yeo Gilsoo was still undergoing endless cycles of regeneration and destruction.

    Though, by now, he no longer resembled a human.

    If one had to describe it, he was nothing more than a lump of flesh—clumped together like clay.

    The experiment results…

    “Successful.”

    Leaving behind the research facility, now engulfed in towering flames, Taeseong walked toward the woods.

  • A doomsday-level returnee devours calamities Chapter 104

    The research facility was fortified to such an extent that calling it Impenetrable would not have been an overstatement.

    As Taeseong walked down the fancy white hallway, gates slammed down in front and behind him, sealing off his path.

    Boom!

    “Quick response.”

    Taeseong found himself trapped in an enclosed space, cut off from all sides by the heavy gates.

    A sharp hissing sound followed, and a deadly poisonous gas was released into the air.

    “A biochemical weapon.”

    It was an extreme toxin, one that not even a gas mask could fully purify. Originally developed for war, its lethality was so overwhelming that it had been outright banned by international wartime conventions.

    But when Taeseong swung his sword, the gate before him was sliced apart like tofu, and in the same motion, he ignited a spark that detonated the toxic gas.

    Boom!

    A massive explosion erupted with such intensity that the walls themselves began to melt.

    Yet from the thick smoke, Taeseong emerged unscathed, his footsteps steady.

    [Intruder detected! Prioritizing target for elimination!]
    [Intruder detected! Prioritizing target for elimination!]
    [Intruder detected! Prioritizing target for elimination!]

    A chorus of mechanical voices rang out.

    Taeseong, intrigued, observed the combat androids now blocking his path.

    Hundreds of them filled the corridor.

    They bore a striking resemblance to humans, but they were not living beings.

    “To think such advanced androids existed… Fascinating.”

    During his time as a soldier, Taeseong had encountered military drones and combat androids before, but he recalled that none had ever achieved the level of efficiency needed for actual battlefield deployment.

    However, the androids before him radiated a presence far beyond anything he had seen.

    Their primary weapon was a plasma blade, an energy-dense weapon of immense lethality. As he observed their intimidating display, Taeseong couldn’t help but admire their craftsmanship.

    “If androids of this caliber were mass-produced, countless soldiers’ lives could be spared.”

    Tat-tat-tat!

    Kicking off the ground, Taeseong dashed forward, dashing across the walls as he plunged into the center of the android swarm.

    [Exterminate! Exterminate!]
    [Prioritize target elimination!]

    Programmed solely for slaughter, the machines lunged at him with perfect precision, swinging their plasma blades.

    “As expected of killing machines, they aim straight for the vitals.”

    They moved as if sharing a single mind, far surpassing even the most highly trained soldiers.

    Unlike humans, these machines did not experience fear.

    A soldier, no matter how seasoned, would inevitably feel terror upon witnessing a comrade’s head explode beside them.

    But these androids did not falter.

    Even as their own were cut down, their limbs crushed, their heads severed, they continued to pursue their single objective—eliminating their target.

    Mindless killing machines.

    That was their sole identity.

    Even as the relentless assault raged on, Taeseong charged forward, unstoppable.

    There was no doubt that these machines were formidable weapons, but the gap in power was absolute.

    With each swing of Sisan Hyulhae, his blade sent out shockwaves of cutting force, shredding everything in its path.

    He was a force of carnage, a demon in battle.

    [Adjusting Delta’s combat level to red-tier threat.]

    [Switching to self-destruction mode.]

    The androids, collapsing like autumn leaves, abruptly altered their strategy.

    Recognizing that they were incapable of eliminating the target through conventional means, they opted for mutual destruction—by detonating their own power cores.

    [3… 2… 1…]

    BOOOOM!

    Hundreds of androids simultaneously self-destructed.

    Even a single one could annihilate an entire area.

    The resulting chain explosion was cataclysmic.

    The facility’s reinforced walls, constructed of special materials, collapsed under the sheer force.

    As the smoke and debris settled, Taeseong rose from the wreckage, casually dusting himself off.

    “That one actually stung a little.”

    His body was covered in scorch marks, but within moments, he was fully healed.

    [……]
    [……]

    Without hesitation, Taeseong surged forward once more.

    No matter how many waves of lethal androids they threw at him, nothing could stop him.

    Had these machines been human, they would have long since abandoned the fight and fled in terror.

    “This time… they’re not even human.”

    He had likely reached the central area of the facility by now.

    Taeseong came to a stop, taking in the grotesque beings blocking his path.

    A chuckle escaped him.

    Before him stood a procession of unnatural creatures—freakish merging of flesh.

    A man stitched together from various corpses, his body an abomination of mismatched limbs.

    A towering figure with three faces and six arms.

    It was as if he had stumbled upon a deranged circus of chimeric monstrosities.

    [Grrr…]
    [Kill… Must… Obey… Master’s orders…]
    [Dad… Mom… I miss you…]

    A wave of disgust washed over Taeseong.

    These were not beings born of their own will.

    They had been artificially created by someone for a specific purpose.

    That was the root of the revulsion he felt.

    “Don’t live as puppets.”

    Taeseong stepped forward.

    A wave of freezing energy radiated from his body, spreading in an instant.

    CRACK!

    Before the chimeras could react, they were frozen solid—transformed into ice sculptures.

    Given their grotesque forms, it resembled some kind of twisted Halloween festival held in a frozen kingdom.

    As Taeseong walked past them, the frozen statues shattered into fine ice particles, fluttering to the ground like snowflakes.

    “Ilhwan, come out, come out, wherever you are.”

    He had been muttering those words the entire time he advanced.

    He was certain that his target was watching him.

    Just as Taeseong predicted, at the far end of the research facility, inside the control room, Park Ilhwan was watching everything unfold.

    Driven to a frenzy, he screamed.

    “Shit! Shit! SHIT! What the fuck is that crazy bastard?!”

    “FUCK! What the hell is that monster?! How the hell is he still alive?! Why won’t he just die?! He’s classified as Delta-tier, goddammit!”

    Even though he was witnessing it with his own eyes, he couldn’t comprehend it.

    Taeseong’s sheer combat prowess had far exceeded any conceivable limits.

    His overwhelming power instilled a primal fear in Ilhwan—someone who had never once felt intimidated before.

    “FUCKING HELL! WHY WON’T HE JUST DIE?!”

    Every trap in the facility.

    Every combat android, engineered for the sole purpose of killing.

    Every chimera, painstakingly created for Ilhwan’s personal use.

    And even an army of mercenaries.

    The entirety vanished in vain.

    ‘Does this even make sense? How can this be real? How is a mere Delta-grade administrator that strong? Is Delta just a cover? Then Gamma? No, could it be even higher? Beta-grade? Are all of the Beta-grade administrators from the Tree this powerful?’

    Whatever the case, Lee Taeseong’s strength defied common sense.

    Even after an explosion capable of wiping out an entire village, he remained unscathed. When he wielded his ominous, blood-soaked sword, walls made of ultra-high alloy were sliced apart like tofu.

    And on top of that, he seemed to have awakened two different abilities, freely wielding both ice and fire.

    “Shit. I can’t accept this. That bastard thinks he can look down on me just because he has some measly power? Saying, ‘Ilhwan, come out, come out, wherever you are’—what, is he mocking me?”

    Muttering to himself, Park Ilhwan tilted his head back, staring at the ceiling before bursting into wild laughter.

    “Keuhaha! Lee Taeseong, you fucking bastard. A worthless piece of shit like you? You think you can stand against me? Do you even know who I am? I’m the second son of Ilseong Group! Do you really think a worm like you can take me down?!”

    Taking a deep breath, Park Ilhwan then spoke toward empty space.

    “Abidos.”

    As if pulling back a curtain, a man appeared from thin air.

    His massive frame was scarred by a grotesque disfigurement, as if half his face had melted away. His right arm and right eye were not flesh but artificial replacements, crafted with advanced technology far beyond what was currently available.

    Using light refraction, he had rendered himself invisible, wearing a cloak that manipulated nanoscale distortions to make his entire body vanish from sight.

    “You called?”

    “Take the job.”

    “Ninety-two more to go.”

    Abidos, the hunting dog.

    He was a Transcender, a fixer from a dimension similar to Earth. Against his will, he had been forcibly transported to this world. In order to return to his own, he made a contract with Park Ilhwan.

    The terms were simple.

    Abidos would act as Park Ilhwan’s hunting dog, fulfilling one hundred requests. In return, Park Ilhwan would use all his resources to find a way to send him back.

    If, after completing one hundred tasks, a way home was still not found…

    Abidos would kill Park Ilhwan.

    That was their agreement.

    “Eliminate Administrator Lee Taeseong. Bring his corpse before me.”

    Abidos gave a slight nod.

    Just then—

    Boom!

    The doors to the control room were violently torn off their hinges. Lee Taeseong had arrived.

    “Found you, Ilhwan.”

    Step. Step.

    His blood-red eyes locked onto Park Ilhwan.

    For a moment, terror seized him, but he forced himself to suppress it. Instead, he clapped his hands together and shouted confidently.

    “Yeah. Fuck. Taeseong, I’ll admit it. You’re goddamn strong. I recognize that. Truly impressive.”

    “……”

    “But you know what? No matter how much you struggle, you’ll never catch me. Do you know why? Because, my dear trash, you were born a fucking loser. That’s just the way it is. Filthy beggars like you always overreach, thinking you have a chance, but in the end, you all get crushed. That’s how the world works.”

    Taeseong, his eyes blazing, slowly advanced.

    “That’s why your parents died the way they did.”

    Bang!

    With a sonic boom, Lee Taeseong’s figure vanished.

    Simply pushing off the ground created a deafening shockwave.

    Extreme high-speed movement.

    He reappeared behind Park Ilhwan, swinging his sword, Sisan Hyulhae.

    Clang!

    Abidos intercepted the strike with his artificial arm, sending a powerful shockwave rippling through the room.

    ‘Fast reaction.’

    The moment was so fleeting that Park Ilhwan hadn’t even realized his throat had nearly been sliced open. But Abidos had managed to track Taeseong’s movement and block him in time.

    “What are you? You seem different from the others.”

    “I’m a fixer.”

    “A fixer? I’m an administrator.”

    A monstrous aura of bloodlust surged from Sisan Hyulhae.

    It condensed into the blade, distorting the very air around it.

    In a flash, Taeseong thrust forward and swung.

    “My job is to deal with scum like you.”

    Abidos upper body was cleaved in two.

  • A doomsday-level returnee devours calamities Chapter 103

    Somewhere underground, in a hidden research facility.

    A man sat before a massive monitor, observing Lee Taeseong.

    His name was Park Ilhwan, the second son of Ilseong Group, the most powerful corporation in South Korea.

    As he watched the screen, he burst into laughter, clutching his stomach as if he had just heard the funniest joke of his life.

    “Puhahahaha! Look at that idiot’s face. Acting all high and mighty, and now he’s completely out of it. Just blanked out!”

    Park Ilhwan nudged a nearby researcher’s shoulder as he laughed hysterically. The researcher forced a smile and replied,

    “Haha! Indeed, sir. Fools like that always overstep their bounds.”

    “Right?”

    “Absolutely.”

    “But… who the hell are you?”

    The researcher, caught off guard, stammered.

    “…Excuse me? You called for me, sir—”

    Slap!

    Ilhwan’s palm cracked across the researcher’s face, whipping his head to the side. A few teeth went flying.

    Yet, despite the pain, the researcher forced another smile and turned back toward him.

    Still smiling, Park Ilhwan spoke.

    “Listen up, you little shit. Who told you to nitpick my words?”

    “I… I apologize.”

    “Hah… Lately, these worms keep thinking they can crawl up the ladder. Stay out of my sight before I decide to kill you. Got it?”

    “…Yes, sir.”

    The researcher bowed politely before hurrying away. He knew better than to linger—Park Ilhwan was the kind of lunatic who would actually kill him.

    With an amused smirk, Ilhwan turned back to the monitor.

    His grin widened as he continued watching Lee Taeseong.

    It had been a long time since anything had piqued his interest. Life had grown boring. Dull.

    But Taeseong… Taeseong was a delightful little anomaly.

    ‘A manager of Tree, huh…’

    Ilhwan was one of the few outsiders who knew about the existence of “Tree.”

    Of course, he had only learned of it through his father, who had given him a brief explanation. The details—how large the organization was, the extent of its influence—had only become clear to him later.

    A memory surfaced.

    You reckless fool. It’s not time yet. Don’t touch Tree.

    Why not?

    Are you really that incapable of figuring it out on your own? What a dimwit… If only you were half as competent as your siblings… Tch.

    Ilseong Group is South Korea’s number one conglomerate. A top-ten global giant. Are you really afraid of some nobodies?

    Nobodies? Hah! You brain-dead idiot. No wonder you lost the succession race. What do you even plan to do with that dull gaze of yours? If you don’t want to lose your last remaining foothold, stop running your mouth and stay put. Even my patience has its limits. Understood?

    Ilhwan never understood.

    His father, the most arrogant, powerful man in the world, had taken a defensive stance.

    Ilhwan never felt any familial affection toward the man, but he had respected him as a person.

    That greed, that ruthlessness, that unwavering decisiveness—Ilhwan wanted to inherit all of it.

    Yet, as far as he was concerned, “Tree” was nothing more than a group of superhumans leeching off their money.

    ‘No matter how strong they are, what can they do without financial backing?’

    Another reason for Ilhwan’s arrogance? He himself was an Awakened.

    Not just a rich brat—he was a chosen rich brat.

    Born with a diamond spoon in his mouth.

    Blessed with supernatural abilities.

    It was only natural for his pride to soar.

    Unlike most Awakened, who suffered traumatic events during their awakening, Ilhwan had it easy.

    From the very moment he awakened, Ilseong Group had provided full support.

    While others endured hardship, Ilhwan walked a golden path.

    His ability? Puppeteer.

    He could create and control dolls.

    The stronger he became, the more dolls he could command, and the stronger they grew.

    The “Ilhwan” that had gone to the villa?

    That had just been one of his dolls.

    He had never been in any real danger.

    That was why he had been so fearless.

    Ilhwan smirked as he switched on the mic, addressing Taeseong directly.

    “Keukeke… What’re you gonna do, huh? What can you even do, you little bitch?”

    Ah.

    This was exhilarating.

    He couldn’t understand why those idiots feared Tree so much.

    ‘My old man’s just a toothless tiger now. Just wait. I’ll take your throne soon enough.’

    To be fair, Ilhwan acknowledged that Taeseong was stronger than expected.

    Surviving that level of bombardment.

    Slaughtering all those mercenaries like they were nothing.

    That had caught him off guard.

    But so what?

    No matter how strong an individual was, what could they do against overwhelming financial power?

    Ilhwan understood better than anyone: an individual could never defeat an organization.

    As he watched Taeseong’s expression darken, his own grin widened.

    The mad dog, running around for revenge, was now lost in despair.

    Yes.

    He had to feel hopeless.

    He had to be overwhelmed.

    But what could he do?

    This was reality.

    A shiver of excitement ran through Ilhwan’s body.

    This thrill—this joy—was precisely why he couldn’t stop toying with these worms.

    “Oh, this is fucking hilarious. Look at that rotten expression. Hey, don’t kid yourself. You awakened your abilities one day and thought you were the protagonist of some comic book? You think you’re the main character of a novel or something? Wake up, Taeseong! Huh? You’re not the protagonist. You’re just a supporting character, existing only to prop up the real leads in this world.”

    After letting it all out, he felt refreshed.

    ‘Can’t you at least shed a tear?’

    He wanted to see that arrogant bastard break down and cry.

    How could he make it happen?

    ‘Ah! Should I kill his only remaining younger sister? Just killing her wouldn’t be fun… Yeah! I should tear her apart limb from limb, wrap her dismembered corpse in her own entrails, and send it to him as a gift!’

    A truly demonic thought.

    At that moment—

    Taeseong, on the monitor, was smiling.

    What the hell? That’s not the reaction I expected.

    His mood soured instantly. He wanted to see the bastard despair…

    Why was he suddenly grinning like that?

    Had he lost his mind?

    Well… yeah, that made sense. Humans often broke down in the face of overwhelming fear.

    It wasn’t like he hadn’t seen it before.

    Thinking of it that way, it was understandable.

    “Did he go insane? What’s so funny—”

    In that instant—

    He felt as if Taeseong, through the monitor, was looking directly at him.

    His glowing red eyes burned like the sun, and a chilling unease surged through him.

    “Found you, you rat.”

    The moment those words left his lips, the monitor went gray.

    Bzzzt—

    Only the sound of static echoed.

    Taeseong had destroyed the drone.

    Park Ilhwan’s expression twisted.

    “‘I found you’? You fucking bastard. What a bluff.”

    …Like he even knows where this place is.

    A strange discomfort crept over him, but he forced himself to brush it off.

    Only a handful of people within Ilseong Group even knew this location existed.

    How could some mere Administrator possibly find it?


    Taeseong soared through the air, black wings spread wide, the sound of wind roaring in his ears.

    At such high speeds, it felt as if a storm was raging inside his head.

    “That must be the place.”

    After destroying the drone, Taeseong had set off without hesitation.

    What Park Ilhwan failed to consider—

    Taeseong had already suspected that Ilhwan was an Awakened, thanks to his earlier conversation with Kim Minji.

    He hadn’t responded to Ilhwan’s taunts because he had been focusing all his efforts on tracking his location.

    Though he didn’t know the exact nature of Ilhwan’s ability, the moment he saw green blood spurting from what appeared to be Ilhwan’s body—

    Taeseong honed his senses to the extreme, tracing the faint energy thread leading back to him.

    Even for Taeseong, this was no easy feat—it required immense concentration.

    But he had succeeded.

    Roughly 400 kilometers away, he could feel the presence.

    “…So that’s why he was so confident?”

    To his surprise, Ilhwan’s energy signature was coming from beneath the ocean.

    The research facility had been built underwater, ensuring that no one would ever find it.

    Suppressing the rage boiling inside him, he steadied his breathing.

    Then, without hesitation, he dove into the sea.

    Following the faint energy signature like a guiding beacon, he swam deep into an underwater cave.

    Breaking the surface, he slicked back his wet hair and muttered,

    “Phew. It’s been a while since I went diving.”

    His body was more than capable of surviving over an hour underwater, but something about being submerged brought back memories of his military days.

    As he moved deeper into the cave, an enormous gate—easily over five meters tall—came into view.

    [NO ENTRY]

    Various warning signs were plastered across it.

    Like the security facilities of Tree, it was designed to open only through multiple layers of authentication.

    “Iris scan, fingerprints, voice recognition… and who knows what else? What a pain.”

    Taeseong had no intention of wasting time on authentication.

    Drawing Sisan Hyulhae from his waist, he clenched his grip.

    His muscles bulged explosively, and in the next instant, his blade cut through the gate in a single diagonal slash.

    Kwoom!

    At the same time—

    Ear-splitting sirens blared, and an automated warning resounded throughout the facility.

    [INTRUDER DETECTED! INTRUDER DETECTED! UNKNOWN ENTITY DESIGNATED AS CODE NAME ‘DELTA.’ INITIATING PLAN C! INITIATING PLAN C!]

    Taeseong walked through the destroyed gate, a grin twisted with madness spreading across his face.

    “Come out, come out, wherever you are.”

  • A doomsday-level returnee devours calamities Chapter 102

    A luxury black sedan was heading toward Sokcho, Gangwon Province.

    At the wheel was Lee Taeseong.

    His destination was a villa in Sokcho, where Park Ilhwan was hosting a secret party.

    Ring! Ring!

    The phone rang.

    “Hello.”

    —”Team leader! Where are you going now?! Don’t tell me… you’re heading to Ilseong Group’s second son? Please, tell me it’s not that!”

    “That’s right.”

    —”Ha… I understand how you feel, but how about stopping here for now? This has gotten way bigger than we expected. The director—no, the branch chief—is furious!”

    “I already settled things with the branch chief when I returned from my assignment in Japan.”

    —”He probably didn’t expect it to escalate this much! Do you know how many high-ranking officials you’ve turned into cripples? More than twenty! Do you realize that twenty people are down because of you?! Thanks to you, South Korea is in complete chaos!”

    “You’ve worked hard. Take care of the cleanup, Chief Choi.”

    Click.

    Taeseong hung up and calmly pressed down on the accelerator.

    Ilseong Group was so influential that no one would dispute it as the pillar of South Korea.

    There was even a joke that the country’s name might soon be changed from “South Korea” to “Ilseong” due to the corporation’s overwhelming power.

    It wasn’t an exaggeration to say that every electronic device used by South Korean citizens belonged to Ilseong Electronics.

    Refrigerators, laptops, desktops, TVs, smartwatches, smart rings, and even electronic cigarettes.

    Because of this, conspiracy theories circulated in online communities, claiming that Ilseong Group possessed every bit of personal information about South Korean citizens.

    Whether that was true or not was something only Ilseong’s insiders would know.

    Taeseong parked near the villa and surveyed the area.

    True to its reputation as the site of Ilseong Group’s second son’s secret party, there were well over fifty security guards in the vicinity.

    Taeseong released a hint of killing intent.

    Yet, strangely, none of the guards collapsed.

    According to past data, even a minute amount of it should have been enough to knock out regular people.

    Some even sensed the malice and started scanning their surroundings.

    ‘Not ordinary people, then.’

    As expected, they were not.

    Each of them possessed the combat ability of at least a Delta-ranked manager.

    They had been dispatched from organizations specializing in security, the very ones Choi Harin had mentioned before.

    However, the difference in level was glaring.

    Up until now, Taeseong had been adjusting his strength to deal with regular people.

    If they thought that was his full power, they were gravely mistaken.

    The moment he released his energy more aggressively, all fifty guards collapsed instantly.

    He stepped inside the villa.

    Yet, contrary to the gathered intelligence, he couldn’t sense any presence inside.

    “…….”

    And then—

    BOOM!

    A deafening explosion erupted as the villa detonated.

    Flames engulfed the entire structure, and his ears rang from the blast.

    Even while his entire body was swallowed by the fire, Taeseong remained calm, analyzing the situation.

    ‘Was this a trap?’

    The explosion was powerful enough to erase the entire villa.

    Yet, Lee Taeseong walked out unscathed.

    He didn’t even need to use his regeneration—his Ignost Flames were more than enough to block the damage.

    Then—

    Clap! Clap! Clap!

    A slow, deliberate applause echoed.

    “How impressive. You survived that explosion.”

    Taeseong’s gaze snapped toward the source of the voice.

    “…Park Ilhwan.”

    “This is the first time we’re meeting face-to-face, isn’t it? Manager Lee Taeseong.”

    Just as Taeseong knew Park Ilhwan’s identity—

    So too, did Park Ilhwan know his.

    ‘So it was all planned from the start?’

    Taeseong swept his gaze around and let out a small scoff.

    A hundreds-strong force encircled him.

    This plan would have been impossible unless they had anticipated his arrival.

    And every single one of them exuded an aura surpassing Delta rank.

    ‘Some of them might even be Gamma-rank…’

    The fact that multiple private organizations could field such forces was unsettling.

    From the very beginning, Park Ilhwan had prepared this place as Taeseong’s grave.

    “You knew I’d come here.”

    “Pfft. Of course I did. You’ve been running around raising hell. If I didn’t know, I’d be a complete idiot, wouldn’t I?”

    “You killed a few vermin and started thinking you could mess with Ilseong?”

    Though his high-end sunglasses concealed his eyes, Park Ilhwan’s smirk was visible.

    It was a mocking grin.

    Taeseong’s gaze sharpened.

    “I’ll give you credit for thinking ahead.”

    Then—

    His crimson eyes flashed ominously.

    “But did you really think this would be enough to handle me?”

    Park Ilhwan mocked.

    “Where the hell does that confidence come from?”

    That was the last conversation they had.

    As if the word “confidence” had fired the signal flare, the mercenaries surrounding Taeseong simultaneously unleashed their attacks upon him.

    Puh-puh-puh-puh-bang!

    The bombardment, reminiscent of modern warfare, concentrated solely on one man.

    The sky was filled with bullets, and all manner of weapons rained down like a storm.

    Jumping into the air, Taeseong drew his sword from subspace. The crimson-stained Sisan Hyulhae cut through the barrage of shells, but with their overwhelming numbers, it was impossible to block them all.

    Watching the scene, Park Ilhwan smiled with satisfaction.

    He was already convinced of his victory.

    “Hahaha! You dumb bastard! You look great!”

    However, as Taeseong spun his body and swung Sisan Hyulhae, a storm of bloodthirsty slashes burst in all directions.

    “He survived that?”

    Shlaaaash!

    In an instant, the bodies of the numerous mercenaries were shredded apart. Each time the merciless red blade touched them, their bodies were torn like paper.

    Some, realizing the disparity in power, attempted to flee, but a black wolf emerged from the shadows, crushing their skulls.

    “Arghhh!”

    “What… what the hell is this?! This isn’t what we were told!”

    “Take down that wolf first!”

    In less than a minute, the mercenaries were annihilated.

    The severed limbs scattered across the ground leaked blood, pooling into dark puddles.

    The name Sisan Hyulhae (Mountain of Corpses, Sea of Blood) was no empty title. The surrounding area was now a literal sea of corpses.

    The bloodstained blade shrieked in delight.

    Having tasted blood, the sword demanded more.

    Understanding its intent, Taeseong answered inwardly.

    Wait. I’ll soon give you the most delicious prey.

    Step. Step.

    Taeseong calmly walked out from the mountain of corpses, his presence resembling that of a grim reaper.

    His red eyes gleamed ominously, and a chilling aura of murderous intent radiated from his entire being.

    Despite this, Park Ilhwan didn’t even blink as he looked at Taeseong.

    “Well, damn… They all died? Do you know how much money I spent on this? Tsk.”

    His reaction was unexpected. Taeseong narrowed his eyes in suspicion.

    All his forces were just wiped out, yet he’s still relaxed?

    Does he still have another card up his sleeve?

    The only conclusion was that he had something left to rely on.

    Otherwise, such confidence would be impossible.

    “If you have a hidden card, you’d better show it now.”

    Hearing that, Park Ilhwan mimicked Taeseong’s words in a mocking tone.

    “‘If you have a hidden card, you’d better show it now.’ Damn, this bastard always acts so dramatic. Where the hell did you get trained? Why are you posing so much? You’re about to die anyway.”

    “……”

    “People who act cocky like you always end up dead. Look at your parents. They kept running their mouths, so I had them killed. If you’re just a bug, act like one. Hm? Know your place and live accordingly. Why do you keep trying to climb up? You don’t even realize that the only reason you’re living comfortably is thanks to Ilseong?”

    Ilhwan openly mocked.

    At his words, a visible aura of murderous intent surged from Taeseong’s entire body, instantly consuming the surrounding area.

    His aura was so intense that merely touching it was enough to tear everything apart, as if struck by a blade.

    Park Ilhwan was no exception.

    Simply being exposed to Taeseong’s killing intent caused blood to trickle from various parts of his body.

    “Wow. Holy shit. This is insane. I might piss myself in fear. There’s no way you’re just a Delta-class. At least Gamma-class, upper rank. Damn those assholes. How dare they try to deceive us?”

    As Taeseong took a step forward, the ground cracked beneath his foot.

    One step.

    Two steps.

    Finally standing right in front of Ilhwan, Taeseong spoke in a low voice.

    His expression was twisted with rage, his face resembling a vengeful deity.

    “Because you were born with a silver spoon in your mouth, you think you’re something special? Do you look down on those less fortunate than you?”

    “Yeah. So what? I am something special.”

    “…Get ready. I’ll show you exactly who you messed with.”

    “Bullshit—”

    Boom!

    Taeseong’s punch struck with such force that even the air pressure alone caused Park Ilhwan’s head to explode.

    A fountain of blood sprayed in all directions—

    But something was off.

    The blood—

    Was green.

    Before Taeseong could grasp the situation, a voice came from a hovering drone.

    It was Park Ilhwan’s voice, laughing mockingly, clearly enjoying himself.

    “Puhahahaha! You dumbass! Did you really think I’d die that easily? Huh? You think the world is that simple? Do you really think the number-one conglomerate in Korea, Ilseong, is that weak?!”

    Taeseong silently glared at the drone.

    As if savoring the moment, Park Il-hwan’s laughter echoed through the speakers.

    “Kehehe. What are you gonna do by staring? Hm? What can you even do, you loser?”

    Just by listening to his voice, it was obvious how much he was enjoying himself.

    “……”

    “Man, this is hilarious. Look at that rotten expression of yours. Hey, do me a favour and stop deluding yourself. Just because you awakened some abilities one day, you think you’re some kind of comic book protagonist? That you’re the main character of a novel? Get real, Taeseong! Hm? You’re not the protagonist. You’re just a side character, existing only to support the real main players of this world.”

    “Haha.”

    “Have you gone crazy? Why are you laughing all of a sudde—”

    At that moment—

    Taeseong cut him off with a meaningful smile.

    “Found you, you rat.”
