Death, as it turned out, did not smell like formaldehyd or rotting flesh. It smelled like ozone, burnt circuitry, and the metallic tang of his own blood pooling beneath his shattered spine.
Kang Han-eol lay on the fractured obsidian floor of the 100th Floor Raid Boss Room, his breath coming in ragged, wet gasps. Above him, the ceiling of the 'Spire of Eternal Night' had collapsed, revealing not the sky of Earth, but a swirling vortex of violet and crimson data streams.
"You did well, Scavenger," a voice callously stated.
Han-eol managed to turn his head slightly. Standing over him was a man in gleaming, golden plate armor that reflected no light. Aris, the Guild Leader of 'Celestial Dawn,' the Rank 1 Guild in the world. His face, usually plastered on screens globally as the 'Savior of Humanity,' was twisted in a smirk of pure contempt.
Behind Aris stood the other nine members of the elite raid team. They looked at Han-eol not with sympathy, but with indifference. To them, he was just a tool that had outlived its usefulness.
"The System promised a unique reward for the first person to clear the 100th floor alone," Aris said, balancing his S-Rank holy sword on Han-eol's chest, right over his failing heart. "But you didn't clear it alone, did you? We let you do the dirty work. We let you find the path. We let you clean the bugs."
Han-eol tried to speak, but only coughed up a clotted glob of blood. His unique class, [The Cleaner (Unique-Utility)], was never meant for combat. It was a trash class, the world said. But Han-eol had used it to survive for ten years, from the moment the Great Patch turned Earth into a lethal MMORPG in 2026.
He wasn't strong. He had the base stats of a Level 10 warrior even at Level 90. But he was smart. He noticed things others didn't. He didn't fight monsters; he fought the architecture they stood on. He didn't dodge attacks; he stepped into "safe zones" where the enemy's attack animation couldn't render. He was the master of exploits, the king of cheese.
And that was why Aris needed him. This 100th-floor boss, 'Null, the Void Eater,' was supposed to be impossible. It had an aura that negated all skills. Aris's holy fire, the Mage's meteors, the Assassin's lethal strikes—all useless.
Until Han-eol found the glitch.
In the southwest corner of the boss room, there was a tiny, flickering texture error on the floor. If you stood on it and precisely channeled mana downward at a frequency of 14hz, the boss's negation aura would register you as an ally due to a priority-coding error.
Han-eol had spent three hours maintaining that channel, taking psychic feedback damage that nearly liquified his brain, while Aris and his team—now immune to the aura—slowly whittled the boss down.
And the moment the boss fell, Aris had used his [Shield Bash] skill not on the boss, but on Han-eol, sending him flying across the room, breaking his body against the wall.
"The reward is mine, Han-eol," Aris whispered, leaning in. "A 'World-Rewrite Ticket.' With this, I can become a true God. I don't need a glitch-abuser like you contaminating my new world."
You hypocritical son of a bitch, Han-eol thought. You used my 'contamination' to get here.
Aris raised his sword. "Goodbye, Scavenger. Your garbage life ends here."
The blade came down.
Han-eol felt the cold steel part his skin, crack his sternum, and pierce his heart. Pain, absolute and blinding, flared for a microsecond before deadening into numbness.
[ Warning: HP has reached 0. ]
[ Death is imminent. ]
But Aris had made one crucial mistake. He had killed Han-eol on the exact coordinate where the Void Eater boss had died just moments before. The area was still saturated with unstable, post-boss-death energy data that hadn't been wiped by the System's garbage collection routine.
Han-eol's vision was blurring into black and white. Yet, through the gray haze, he saw it.
Right where his blood mixed with the boss's dissipating ashes, the air itself was flickering. It wasn't a graphical error this time. It was a rip in the game's source code. A 'Null-Byte Zone.'
If I'm going to die, Han-eol thought, a surge of adrenaline bypassing his dead nerves, I'm taking your reward with me.
With his final ounce of strength, using the last point of mana he had, Han-eol activated his Class-specific skill, a skill he had never used because it required a 'fatal system instability' to trigger.
[ Skill Activated: Purge (Lvl Max) ]
[ Target: The reality coordinates you occupy. ]
[ WARNING: This action is irreversible and may lead to data corruption. ]
Han-eol didn't target Aris. He targeted the gap in the world.
Purge.
A shockwave of white noise exploded from his body. Aris's triumphant look turned to terror as the very floor beneath them began to de-rez, turning into blue blocks of void. The golden savior screamed as he fell, not into the floor below, but out of the game's rendering map entirely, deleted from existence.
Han-eol smiled as the white noise consumed him too.
[ Critical Error! ]
[ Core Loop Compromised. ]
[ User data 'Kang Han-eol' is intersecting with a compressed data packet: 'The Save State'. ]
[ Attempting to resolve intersection... ]
[ Error. Error. Error. ]
[ Paradox Detected. ]
[ Activating Emergency Protocol: Rollback. ]
The feeling of being deleted was replaced by a sensation of being stretched through a straw. Time didn't just stop; it rewound. He saw his life play backward—the ten years of suffering, the death of his sister, the day the sky turned blue.
Rollback to last stable configuration.
[ System Announcement: The Great Patch is about to be deployed. ]
[ Current Time: June 1st, 2026. 09:59 AM (KST) ]
[ Please prepare for Initialization. ]
Han-eol gasps, his lungs burning as they inhale air that doesn't smell like ozone. He snaps his eyes open.
He is not in the Spire. He is in a crowded, slightly grimy convenience store in Seoul. The fluorescent lights hum overhead. A teenage girl nearby is giggling at something on her phone. The cashier is lazily scanning a bag of chips.
Han-eol stumbles back, hitting a metal shelf filled with instant ramen. The shelf rattles.
"Hey, watch it!" the cashier barks, looking up.
Han-eol ignores him. He is staring at his hands. They are thin, calloused from hard work, but whole. No scars from goblin claws. No burn marks from rogue mages.
He fumbles in his pocket and pulls out a phone. Not the cracked, reinforced military-grade device he had in the Spire, but a cheap, three-year-old model.
The date on the screen: June 1st, 2026. 09:59:30 AM.
"It... it worked," he whispers, his voice cracking with a mixture of disbelief and sheer, unadulterated relief. The 'Null-Byte Zone' hadn't just deleted him; it had collided with his 'Cleaner' data and triggered a system rollback—a regression. He had gone back ten years, to the exact moment the nightmare began.
His heart pounds against his ribs—a whole heart, unpierced by Aris's sword.
"Aris," he breathes the name, and it feels like venom on his tongue. He remembers Aris's face in those final moments. He remembers the arrogance, the betrayal.
"In this life," Han-eol says, his hands clenching into fists, "you won't even get past the 10th floor. I'm going to take everything you think you're entitled to."
But revenge has to wait. Survival comes first.
He looks at the clock. 09:59:45 AM.
Only fifteen seconds left. In his past life, Han-eol had been here, in this very store, buying bread for his younger sister, Han-ji. When the Initialization hit, the store had been overrun by Level 1 Goblins within minutes. He had survived only by hiding inside the industrial freezer for two days, nearly freezing to death while hearing the screams of the people outside.
He had been weak. He had been a victim.
Not this time.
Han-eol spins around, scanning the store with eyes that had seen a decade of death. He needs a weapon, and he needs it now. He doesn't look at the 'cool' things. He looks for utility.
His eyes land on a display near the entrance. Umbrellas. Cheap, $2 black plastic umbrellas.
The cashier watches him, bewildered, as Han-eol grabs one and rips off the plastic plastic sheath.
"Hey, kid, you gotta pay for tha—"
[ 00:00:03... ]
[ 00:00:02... ]
[ 00:00:01... ]
The hum of the fluorescent lights stops. But the lights don't go out. Instead, they glow with a searing, unnatural blue intensity. Outside the windows, the bright morning sky transforms into a deep, abyssal indigo.
And then, the screens appear.
They are everywhere. In the air, over people's heads, reflecting in the windows. Simple, rectangular blue holographic interfaces with white text.
[ Welcome, Citizens of Earth. ]
[ Current Status: Server v0.9 (Pre-Alpha) – FAILED. ]
[ Status Update: Commencing Patch v1.0 (The Great Patch). ]
[ Deploying Game Mechanics... ]
[ Assigning Baseline Stats... ]
[ Integrating Local Flora and Fauna... ]
A woman near the back screams, her phone dropping to the floor. "What is this? My phone isn't working! What are these screens?"
Panic is immediate. It spreads like a wildfire in a dry forest. People are pushing, rushing toward the door. The cashier is screaming into a landline that is clearly dead.
Han-eol doesn't panic. He feels an icy calm settle over him. He knows what comes next.
[ Tutorial Quest: 'Survival of the Fittest' ]
[ Objective: Survive for 30 Minutes. ]
[ Failure: Death. ]
[ Success: Access to the System Interface. ]
[ Good luck, Players. ]
The sound of shattering glass echoes across the street. And then, the shrieks.
A shadow darkens the convenience store entrance. A creature, roughly three feet tall, with mottled green skin, long pointed ears, and teeth like jagged shards of glass, steps through the doorway. It clutches a rusty kitchen knife. A Lesser Goblin.
Behind it, three more appear.
The customers near the front shriek and bolt toward the back, deepening the chaos. The cashier tries to hide behind the counter.
Han-eol doesn't move. He stands in the center aisle, holding his cheap plastic umbrella like a master swordsman holding a katana. He looks at the first goblin. Over its head, a floating red bar and text appear:
[ Lesser Goblin (Lv. 1) ]
The goblin sees Han-eol. It smirks, revealing rotten gums, and lifts its knife. To the goblin, this human looks identical to all the other soft, screaming sheep it had just slaughtered on the street.
The goblin lunges.
It's an amateurish attack, a direct vertical slash born of raw instinct, not skill. To the ten-year veteran, it's slow motion.
Han-eol doesn't block. He doesn't dodge.
He steps forward.
But not just a forward step. He takes a half-step to the left, angling his body precisely 15 degrees. His left foot lands on a cracked tile on the convenience store floor—a tile he remembered from his previous life, the one where the store's collision map had a pixel-wide discrepancy.
When he lands on that spot, at that angle, while not in a dynamic movement state (like running), the System's physics engine has a rounding error. It fails to calculate his 'physical volume' correctly.
The goblin's knife descends. The rusty blade should have carved from Han-eol's shoulder to his waist.
Instead, the blade, and the goblin itself, passes completely through Han-eol's body.
It's as if Han-eol had momentarily become a ghost.
The goblin, having met zero resistance, is pulled forward by its own momentum. It tumbles past Han-eol, crashing headfirst into the metal display of potato chips. Chips explode in a cloud of salty dust.
[ Alert! An unexpected error has occurred in the 'Physical Collision Box' calculation. ]
[ Recalculating... ]
"Recalculate all you want," Han-eol mutters, gripping the plastic handle of the umbrella.
He doesn't wait for the System to fix the bug. The glitch only lasts for 1.5 seconds.
Han-eol spins on his heel. The goblin is still disoriented, trying to push itself out of a bag of sour cream and onion chips. Its back is exposed.
"This," Han-eol says, the umbrella pointed like a rapier, "is for the freezer."
He doesn't activate a skill. He doesn't have mana yet. He just uses physics.
He performs a simple thrust. But right before the tip of the umbrella makes contact with the goblin's neck, Han-eol does a micro-jump, lifting both feet off the ground for a fraction of a second.
In this Pre-Alpha version of the patch, doing a thrust attack while in a 'Zero-G' state (even the micro-G of a tiny jump) causes the damage algorithm to glitch. It cannot resolve the momentum, so it defaults the attack to have a 'Maximum Velocity' modifier.
It's a glitch he had discovered while fighting harpies in the sky.
The cheap plastic tip of the umbrella hits the goblin's thick neck skin. But with the glitch applied, it doesn't bend or snap. It pierces the flesh as if the umbrella were a high-caliber anti-material rifle round.
KRA-CHAAK.
The umbrella travels completely through the goblin's neck, popping out the other side. Black, tar-like blood sprays all over the chip display.
The goblin lets out a gurgling shriek, its body convulsing before going still.
The chip bags begin to dissolve into white blocks of data as the monster's body de-rezes.
[ You have defeated a 'Lesser Goblin' (Lv. 1)! ]
[ Due to the difficulty gap (No Equipment/No Skills), bonus experience is awarded. ]
[ You have leveled up! ]
[ Your Level has increased from Lv. 1 to Lv. 2. ]
[ 5 Stat Points have been awarded. ]
Han-eol ignores the screens. He rips the umbrella out of the dissolving corpse. The plastic is coated in black gunk, but it's still whole.
The other three goblins have stopped their pursuit of the customers. They are staring at Han-eol, and then at the pile of dissolving pixels that used to be their leader. The initial smirk of dominance is replaced by primal confusion, and then rage.
A human had just killed one of them. And he had done it with a stick.
"Gah-roook!" one of the goblins roars, a signal. All three of them discard their other targets and encircle Han-eol.
They aren't going to lunge one by one. They are going to pack-tactics him. One from the left, one from the right, one from the front.
It's a classic pincer. A guaranteed death sentence for any Lv. 1 player without an area-of-effect skill.
And Han-eol is still technically Lv. 1 in terms of physical ability, despite the level-up notification.
He smirks. Perfect.
He backs up slowly, leading them away from the metal shelves and toward the glass beverage coolers at the back of the store.
"Come on," Han-eol gestures with the bloody umbrella. "I'm right here."
The left goblin yaps and lunges first, aiming low at his legs. A moment later, the front goblin jumps high, aiming for his head. The right one circles to his back.
It's coordinated. Impressive for mere goblins.
Han-eol, however, is not looking at them. He is looking at the glass of the beverage cooler he is standing in front of.
Specifically, he's looking at the reflection. The intersection of his current position, the reflection of the goblin behind him, and the glass's own geometry.
If he was an ordinary player, he would try to parry. He would fail.
But Han-eol is a Scavenger.
He doesn't attack the goblins.
He activates a base stat allocation. It's a mechanic most players won't discover until after the tutorial: you don't need to be in the interface menu to allocate stats; you can do it with a mental command.
All 5 points into Agility, he commands.
A surge of electricity rips through his muscles. It's not a magical effect; it's a raw biological imperative. His brain is now processing time slightly faster, his muscles capable of faster contraction.
With his new Agility, he executes a movement that is physically impossible according to the standard motion engine.
As the left goblin swipes, Han-eol drops into a split. Not a perfect, practiced split, but a brutal, bone-cracking drop.
The goblin's knife misses his leg by an inch.
But the glitch isn't the split. The glitch is what happens after.
Because he put all his points into Agility while performing a maximal extension of his muscles (the split), the system's drag coefficient algorithm fails to apply.
Han-eol uses his hands to push off the floor. The new agility, coupled with the friction glitch, launches him backward at three times his maximum speed. He doesn't slide; he teleports backward.
He zips through the tight gap between the left goblin and the center goblin.
The two goblins, having both lunged with full force, collide. The left one's knife sinks into the center one's stomach. The center one's claws rip across the left one's face.
"GAHHH-RAAAGH!"
They fall to the floor in a tangled mess, stabbing and clawing at each other in a frenzy of friendly-fire panic.
One goblin left. The one who was trying to circle behind him.
This goblin is now staring at where Han-eol was, and then at his two companions mutilating each other. It is utterly lost. Its AI brain is looping.
Han-eol is now standing ten feet away, by the cash register. He has the umbrella. And he has a new target.
Above the cash register, there's a heavy, industrial-grade fire extinguisher mounted to the wall.
Han-eol knows that in this v1.0 patch, 'Object Durability' is glitchy. Environmental objects don't take damage gradually; they have a threshold. If you hit an object with precisely 7.7% of its maximum durability's force, the object won't break—it will launch. The physics engine interprets the force not as damage, but as a directional vector.
Han-eol hurls the plastic umbrella. Not at the goblin, but at the fire extinguisher.
He applies the 'Maximum Velocity' glitch again by jumping and thrusting (throwing, in this case) in a zero-G state.
The umbrella hits the bottom of the fire extinguisher with a deafening CLANG.
The umbrella shatters into a thousand plastic splinters.
But the fire extinguisher doesn't break. It doesn't even dent. Instead, it is ripped from its wall mount and launched across the room like a rocket. A hundred pounds of steel, flying at a hundred miles per hour.
It hits the remaining goblin square in the face.
There is no scream. There is only the wet, crunching sound of a watermelon exploding against a concrete wall. The goblin's entire upper body is vaporized by the force of the 'launched object' glitch. What remains drops to the floor like a sack of garbage.
[ You have defeated a 'Lesser Goblin' (Lv. 1)! ]
[ Critical Hit Bonus XP awarded! ]
The two goblins on the floor, now finally separating, look at their headless companion. They look at Han-eol, who is standing calmly by the register, his hands empty.
They look at the blue screens that are now flickering wildly.
[ Alert! Anomalous player behavior detected. ]
[ Physics Engine stability: 92%. ]
[ 'Developer' eyes are drawing toward the Seoul Sector... ]
For the first time since the tutorial started, the goblins feel a new emotion: Fear. They are not fighting a human. They are fighting something that violates the very laws of the game they were summoned to populate.
They turn. And they run.
The two surviving goblins bolt out of the shattered front entrance, ignoring the other customers, their only instinct now to get as far away from Kang Han-eol as possible.
Silence falls over the convenience store.
The blue, oppressive light from the sky still filters through the broken windows. Outside, the screams are still happening, though they sound more distant now.
The customers in the back of the store look at Han-eol with a mixture of awe and absolute terror. They are all thinking the same thing: Who is this guy? And how did he know to do that?
Han-eol walks past them, his face impassive. He approaches the pile of dissolving chips where his first kill was. Near the dissolving body, something shiny glitters on the tile floor.
A drop. Goblins almost never drop items in the Lv. 1 tutorial. But because he had killed it with no gear and using an 'exploit,' the drop algorithm had triggered a 'Rarity Error.'
It's a ring. A simple, silver band set with a single, pulsing green stone.
He picks it up. A blue interface box appears above it.
[ The Glitched Band of the First Kill (Unique-Bugged) ]
[ Type: Ring ]
[ Requirement: Kang Han-eol ]
[ Description: An item that should not exist. A ring born from the intersection of a rollback state and a system glitch. ]
[ Static Effect: Intelligence +30 (Normal Intelligence for a Lv. 1 player is 10). ]
[ Active Skill: Save Point (Bugged) – Create a fixed save coordinate in reality. If you die within 10 minutes of creating the Save Point, your data is restored to that coordinate with 1 HP and 1 Mana. Use is only possible once per 'Patch' phase. Current state: Unused. ]
Han-eol's hand trembles.
"Intelligence +30..."
This single item has more stat points than Aris had after clearing the 10th floor boss. And that 'Save Point' skill... that wasn't a skill. That was a developer's debug tool. And it was unique to him.
He slips the ring onto his finger. He feels a sudden, profound lucidity. His thoughts are sharper. The details of his previous life are no longer a hazy nightmare; they are as clear as a high-definition movie. He can recall every boss pattern, every glitch location, every secret path Aris and the other Ranker guilds had guarded so selfishly.
"Unique-Bugged," Han-eol whispers, looking at the ring, then looking up at the sky where the massive, indigo-colored 'Developer' eyes were beginning to peer through the atmospheric data streams, watching the "failure" that was the Earth server.
"You called our world a 'failed Pre-Alpha server,'" Han-eol says, addressing the sky, addressing the very developers who had killed humanity with indifference.
"You said you were patching us to fix us."
He clenched his fist, the green stone of the ring pulsing like a heartbeat. A new notification, different from the standard system blues, appeared before his eyes. It was a chaotic, flickering violet.
[ You have acquired a 'Hidden' Class. ]
[ Class Name: The Sovereign of Glitches (Origin-Bugged). ]
Han-eol's smirk returned, cold and terrifying.
"This time," he said to the void, "I'm the one who's going to find the hole in your game. And when I do, I'm not just going to cheat. I'm going to delete the source code."
The tutorial was only just beginning. The first 30 minutes hadn't even passed. But as the screams of the dying world continued outside, Kang Han-eol knew one thing with absolute certainty.
He had already won. He just had to make the developers watch him break their universe, one glitch at a time.
