The neon sign of the "Gwangmyeong 24-Hour PC Cafe" flickered with a dying buzz, casting a sickly green light over the rain-slicked pavement. Jin-ho stood in the shadow of the alleyway, his hoodie pulled low. To the world, he was just another exhausted college student or a runaway. To the sensors of the Seoul Hunter Association, he was a "Zero-Point" ghost.
He checked his cracked smartphone. 4:15 AM.
The "official" gates were guarded by Guild-sanctioned security teams and high-resolution mana-scanners. A Level 19 with a hidden S-Rank signature would trigger every alarm in the district. But Jin-ho wasn't looking for an official gate. He was looking for a "Leaking Fissure."
In the outskirts of the city, where the skyscrapers gave way to rusted factories and crumbling apartments, the fabric of reality was thinner. Small, E-Rank fissures opened constantly—too weak to be a threat, too small to be profitable for the big guilds.
[The Eye of the Void: Active]
Jin-ho's vision shifted. The world turned a desaturated grey, but pulsing through the brickwork of an abandoned textile factory was a jagged, electric-blue vein of energy.
Found you.
He hopped a chain-link fence, his new Agility stat making the three-meter jump feel like stepping over a curb. Inside the factory, the air was thick with the smell of motor oil and ancient dust. In the center of the floor, a vertical tear in space hummed with a low, predatory vibration.
[Notice: You are entering an Unregistered Fissure.]
[Difficulty: D-Rank (Mutated)]
[Warning: No Extraction Point detected. Clear the Boss to exit.]
Jin-ho didn't hesitate. He stepped into the blue tear.
### The Iron Hive
The transition was instantaneous. The factory floor vanished, replaced by a labyrinth of metallic tunnels. The walls weren't stone; they were composed of interlocking copper plates and humming brass pipes. Steam hissed from overhead vents, smelling of ozone and sulfur.
[New Territory: The Copper Labyrinth]
[Monster Type: Mechanical-Insectoid]
Jin-ho reached into his pocket. He didn't have his daggers—they were slag. Instead, he pulled out a pair of heavy-duty industrial rebar cutters he'd taken from a construction site. They were crude, heavy, and lacked any magical conductivity.
It doesn't matter, he thought. The System will make them work.
From the darkness ahead, a mechanical clicking sound echoed. It started slow, then accelerated into a frantic skittering. Out of the shadows emerged a "Copper Scuttler"—a creature the size of a wolf, with six serrated legs made of sharpened brass and a glowing red orb for a head.
[Target: Copper Scuttler (Level 12)]
[Threat: Minimal]
The monster lunged, its metallic legs sparking against the floor. In the past, Jin-ho would have died instantly. He wouldn't have even seen the movement.
But now, the world was slow.
He watched the Scuttler's trajectory. He could see the tension in its hydraulic joints. He could see the "Neural Core"—a pulsing violet spark deep inside the red orb.
Jin-ho didn't dodge. He moved forward.
He swung the rebar cutters. He didn't use mana; he used Internalization. The golden aura flared from his palms, flowing into the rusted iron of the tool. The rebar cutters didn't just hit the monster; they sheared through the brass armor as if it were warm butter.
CRACK.
The red orb shattered. The Scuttler's legs gave out, its internal gears grinding to a halt before exploding in a shower of sparks.
[Experience Gained.]
[Level 19: 12.5% -> 13.8%]
Jin-ho didn't stop to celebrate. The sound of the explosion had alerted the hive. From the vents, the walls, and the ceiling, dozens of red orbs began to blink into existence.
"Good," Jin-ho whispered, a dark thrill racing through his blood. "I need the XP."
### The Aurelian Dance
For the next hour, Jin-ho became a whirlwind of golden light.
He stopped thinking about his movements as "combat." It was more like a rhythmic calculation. The System fed him data—wind resistance, joint durability, mana-density—and his body responded with a precision that was almost terrifying.
He took a hit to the shoulder from a larger "Brass Soldier," a humanoid machine with a steam-powered mace. The impact shattered the skin, drawing blood, but Jin-ho barely felt it.
[Passive Skill: 'Pain Suppression' (Temporary) has been activated.]
[Condition: Adrenaline Peak.]
He spun, driving the blunt end of the rebar cutters into the Soldier's chest.
BOOM.
The golden shockwave blew the monster backward, its chest cavity caving in.
Jin-ho's breathing was heavy, his t-shirt soaked in sweat and black oil. He felt the Level Up notifications stacking in the corner of his eye, but he ignored them. He was chasing a specific feeling—the moment when his "Sync Rate" would tick upward.
[Sync Rate: 2.1% -> 2.2%]
It was too slow. At this rate, it would take years to reach his full potential. He needed something stronger. He needed to push the System until it screamed.
He reached the center of the Labyrinth—a massive boiler room where the pipes converged into a pulsating, metallic heart. Standing before the heart was a monster that didn't belong in a D-Rank fissure.
[WARNING: Boss Entity Detected.]
[Name: The Great Gear-Warden]
[Rank: B (High)]
[Current Win Probability: 14%]
The Warden was fifteen feet tall, a colossus of brass and steam. Its "head" was a massive clock face, and its "arms" were heavy industrial pistons. It didn't skitter; it walked with the weight of an earthquake.
"Fourteen percent?" Jin-ho spat blood onto the metallic floor. "That's more than I had yesterday."
### Overclocking
The Warden raised a piston-arm. The air hissed as steam built up in its chambers.
WHAM.
The floor where Jin-ho had been standing a millisecond ago was flattened. Jin-ho was already in the air, aiming for the Warden's clock-face. But the Warden was fast—it swatted him out of the sky like a fly.
Jin-ho slammed into a cluster of hot pipes. He felt a rib snap. His vision blurred.
[Health: 22%]
[Warning: Critical Damage to Internal Organs.]
Not enough, Jin-ho thought, his fingers digging into the metal. I gave those levels to Mom so she could live. If I die here, it was all for nothing.
He looked at the Warden, which was charging its steam cannons for a finishing blow.
"System," Jin-ho croaked. "Whatever 'Overdrive' you have... give it to me. All of it."
[Warning: Manual Overclock will cause permanent cellular damage.]
[Do you wish to proceed?]
"Do it!"
[Initializing... 'Aurelian Overdrive' (Level Max - Forced).]
[Sync Rate: 2.2% -> 5.5% (UNSTABLE)]
The world didn't just slow down; it stopped.
The steam escaping the Warden's vents froze in mid-air. The sparks from the grinding gears hung like diamonds in the darkness.
Jin-ho's skin began to glow, not with the faint aura of before, but with a blinding, incandescent white-gold light. His hair stood on end, arcs of blue lightning dancing between the strands.
He didn't run. He ignited.
He was a golden streak. He hit the Warden's leg, and the brass shattered. He hit the Warden's arm, and the piston melted. He was moving so fast that the friction of his passage began to heat the air in the room to a plasma state.
The Warden tried to track him, its clock-face spinning wildly, but it was fighting a ghost.
Jin-ho appeared directly in front of the Warden's core. He didn't use the rebar cutters. He balled his fist, the golden energy condensing into a point of infinite density.
"Equivalence," Jin-ho whispered.
[Skill: 'The Great Equalizer' - Kinetic Transfer.]
He punched the core.
The sound wasn't an explosion. It was a vacuum. For a split second, all sound in the factory vanished as the kinetic energy was transferred from Jin-ho's soul into the Warden's frame.
Then, the world returned with a roar.
The Warden didn't just break; it disintegrated. The fifteen-foot colossus was reduced to metallic dust in a single heartbeat. The shockwave blew the roof off the textile factory, sending a pillar of golden light into the early morning sky.
### The Quiet Aftermath
Jin-ho collapsed.
The Overdrive vanished, leaving his muscles feeling like they were filled with broken glass. He lay on the cold, oily floor of the factory, staring up at the hole in the roof. Rain began to fall, cooling his scorched skin.
[Boss Slain.]
[Calculating XP...]
[Level 19 -> 20... 25... 28... 30.]
[You have reached Level 32.]
[Hidden Stat 'Sync' has reached 6.0%.]
[New Skill Unlocked: 'Inventory - Sub-Space.']
Jin-ho closed his eyes, his chest rising and falling in shallow gasps. Level 32. In one night, he had surpassed the average B-Rank hunter.
He felt a weight in his hand. He looked down. The rebar cutters were gone—vaporized. In their place was a single, glowing blue crystal.
[Item: Core of the Gear-Warden (Rank B).]
[Market Value: 150,000,000 Won.]
"One hundred and fifty million," Jin-ho laughed, a dry, hacking sound. "Mom... I can pay for the whole floor now."
But as he sat up, his "Eye of the Void" flickered.
Through the hole in the roof, he saw them. Two figures standing on the edge of the neighboring skyscraper. They weren't wearing hunter gear. They were wearing black, formal suits, and they were holding devices that pulsed with a familiar, golden light.
They weren't looking for monsters. They were looking at him.
[System Warning: High-Level 'Architects' detected.]
[Estimated Combat Capability: Error.]
[Recommended Course of Action: Escape.]
Jin-ho stood up, his legs shaking. He didn't have his daggers. He didn't have his energy. But as he looked up at the watchers on the roof, he didn't feel afraid.
He felt a cold, sharp hunger. "Is that all you've got?" he whispered to the shadows.
He reached into the air, and for the first time, his "Inventory" opened—a shimmering rip in reality. He placed the Gear-Warden's core inside and stepped out of the factory ruins, disappearing into the Seoul morning before the Association helicopters could arrive.
The Porter was dead. The Glitch was active. And the world was finally starting to notice.
