Chapter 79: Zero Point

Dying felt like falling asleep in a bathtub full of ice water.

Jin's HP counter ticked through single digits while Do-yun's hand cooked the skin off his throat. The numbers meant less than the sensation—a pulling at the center of his chest, like gravity had decided his ribcage was the lowest point in the universe. Everything rushed inward. His vision narrowed to a pinhole. Sound became distant, muffled, the way voices sounded through a closed door in a house you were leaving for the last time.

Do-yun was saying something. Jin couldn't hear it.

**[HP: 3... 2... 1...]**

**[WARNING: LETHAL THRESHOLD]**

**[ANOMALY RESPONSE: INITIATING]**

**[ERROR: DEATH PROTOCOL NOT FOUND FOR NEGATIVE-LEVEL ENTITY]**

**[ERROR: ERROR: ERR—]**

Zero.

Jin's heart stopped. His lungs locked. His brain, deprived of oxygen for exactly 1.7 seconds, began the cascade shutdown that every living thing experiences when the machinery of life grinds to a halt.

Then something happened that the System couldn't classify.

The inverse energy that lived in Jin's cells—the wrongness that made him what he was, that turned damage into healing and weakness into strength—had nowhere left to go. With his body shutting down, the conversion engine at his core hit a dead end. Pain Drinker had nothing to feed into. His constitution had no vessel to sustain.

So the energy went out.

It wasn't an explosion. Explosions were dramatic, directional, understandable. This was more like a hiccup in the fabric of reality—a bubble of inverted physics that expanded from Jin's body at the speed of thought and popped after covering a radius of maybe five meters.

Inside that bubble, for one-third of a second, everything worked backwards.

Do-yun's fire froze. The heat became cold so intense that ice crystallized on his knuckles, and the hand gripping Jin's throat spasmed open as the thermal shock hit nerves designed for burning, not freezing. The gravity manipulator, still recovering on the ground nearby, suddenly weighed nothing and drifted upward a meter before the effect collapsed. The blade user's weapon rusted through decades of corrosion in an eyeblink, crumbling to orange dust.

And Jin's heart, which had stopped, started again. Not because it was supposed to—because in an inverted bubble, stopping meant starting.

He dropped from Do-yun's grip like a sack of wet cement.

The concrete was blessedly cold against the burns covering his chest and arms. Jin lay there for one full second, cataloguing damage: third-degree burns on sixty percent of his torso, crushed windpipe partially reconstructed by the inverse pulse, multiple lacerations still bleeding, one eye swollen shut. His HP had reset to something above zero—not much, maybe forty or fifty points—but enough. Pain Drinker had reengaged and was frantically converting the residual burn damage into trickles of healing.

Do-yun staggered back, staring at his frost-burned hand. "What the fuck was that?"

Jin didn't explain. Couldn't, actually, because his throat was a tube of raw hamburger and speaking required muscles that weren't currently functioning. Instead he rolled onto his stomach, got his hands under him—the burned palms screaming as they took his weight, Pain Drinker gulping down the fresh pain—and crawled.

Not heroic. Not dramatic. He crawled across the alley like a man dragging himself out of a car wreck, leaving a smear of blood on the concrete behind him.

"Shoot him," Do-yun said. His voice had lost the restaurant-reservation smoothness. Something had rattled him—the inverse pulse, the impossibility of it, the moment where his fire had turned to ice. "Kill him before he does that again."

Footsteps behind Jin. Running. He could hear them through the ringing in his ears—boots on pavement, the click of a weapon being readied, someone's breathing harsh and fast.

The loading dock door was three meters away. The sub-basement stairs were beyond it. Three meters. He could do three meters.

Something hit him in the back. A mana bolt—concentrated, Level 60-something, designed to punch through barriers. It went through the leather jacket and into the muscle between his shoulder blades, and the pain was a white spike that drove the air from Jin's reconstructed throat.

Pain Drinker took it. Converted it. The healing flowed downward, reinforcing his legs, feeding his arms. Jin used the burst to lunge forward, grabbed the door frame, and pulled himself through.

More impacts. Someone's ability hitting the door frame behind him, blowing chunks of concrete into the air. A gust of heat as Do-yun threw fire that splashed against the loading dock wall and ran down it like burning water.

Jin fell down the stairs.

Not intentionally. His legs gave out on the second step and he tumbled the remaining twelve, each impact a gift of pain that Pain Drinker processed greedily. By the time he hit the sub-basement floor, he'd gained back enough HP to stand.

So he stood. And he ran.

---

The tunnels were dark and they stank and the walls were slick with condensation that had been building since the Japanese occupation, and Jin loved them with the desperate gratitude of a drowning man who finds a rope.

He ran with one hand on the wall for guidance, his one functional eye adjusting to the darkness, his burned skin sticking to his ruined jacket with every stride. Behind him, the sounds of pursuit—Do-yun's squad entering the sub-basement, voices bouncing off concrete, the glow of someone's light ability pushing shadows ahead of them through the tunnel.

They were faster than him. Healthier. They hadn't been cooked alive two minutes ago.

But they didn't know the tunnels.

Jin did. Four weeks of hunting Grey-Class down here had given him a mental map that no GPS could match—every junction, every collapsed section, every spawning point where dimensional energy pooled thick enough to birth monsters. He cut left at a junction the Iron Wolves would have to guess at, then right through a narrow passage where the ceiling dropped low enough to force him into a crouch.

The pursuit sounds faded. Not gone—Do-yun wasn't stupid, and he had enough hunters to split up and cover multiple routes—but farther. Buying time.

Jin kept moving. The burns on his chest cracked and wept with every step, each fresh spike of pain feeding Pain Drinker enough to keep his legs working. A horrible economy: his injuries were the fuel that kept him mobile, which was what the System had always intended, or never intended, or—

He heard them before he saw them.

Voices ahead. Low, urgent, the controlled panic of people trying to be quiet while also trying not to die. A child whimpering. Someone shushing. The scrape of feet on wet stone.

Jin rounded a bend and found the Forgotten.

They were bottlenecked at a junction where the main southern route had collapsed—a wall of rubble and broken pipe that blocked the passage completely. Sung-joon stood at the front of the group, tablet glowing in the darkness, trying to calculate an alternative while thirty scared people pressed against his back.

"Route two is gone," Sung-joon said when he saw Jin. Then he looked at Jin properly, and the tactical assessment in his eyes gave way to something closer to nausea. "Jesus. Your skin—"

"Doesn't matter. What routes are left?"

Sung-joon swallowed whatever he'd been about to say about Jin's appearance and pulled up his map. "One. The eastern branch. It connects to the old drainage canal under Yongsan, but—"

"But it goes through the Grey-Class spawning zone."

"Yeah." Sung-joon looked at the crowd behind him. Thirty people. Children. Elderly. Baek Yuri with her useless healing sparks. Won-shik with his structural sense that was currently screaming about load-bearing weaknesses in every wall around them. "We can't take non-combatants through a monster spawning zone."

"We can if I go first."

Min-ji pushed through the crowd. She'd been in the middle of the group, treating a twisted ankle on one of the older members. When she reached Jin, her clinical mask held for exactly one and a half seconds before fracturing.

"Your dermal layers are—have you been—" She reached for his arm, then pulled back, her hands hovering over burns she couldn't treat. Couldn't touch. Because her healing would hurt him, would invert and become damage layered on top of damage already there. The one person in the group trained to treat injuries, and she was the one person whose treatment would make it worse.

Her hands shook. Just slightly. Just enough for Jin to notice.

"I need you to not heal me," Jin said. "Specifically. If you could also not look at me like that, I'd appreciate it."

"Like what?"

"Like I'm one of your patients."

"You're not my patient. You're an idiot with third-degree burns across most of his upper body who's about to volunteer to fight monsters in a tunnel." Her voice cracked on the last word. She caught it, rebuilt it, pressed on. "What's your current HP?"

"Higher than it was five minutes ago." Which was technically true.

"That's not an answer."

"It's the one I've got. Let's move."

---

The eastern branch narrowed after the first hundred meters, the ceiling dropping and the walls pressing close enough that the larger Forgotten members had to turn sideways. The air changed too—thicker, warmer, carrying the fungal smell that Grey-Class spawning zones always produced. Dimensional energy collected in these dead-end passages the way water collected in low ground, and where dimensional energy pooled, things grew.

Jin went first. Always first. The burns on his body were Pain Drinker's ongoing buffet—every flex of damaged muscle, every brush of ruined skin against his jacket, every step that jarred the hairline fracture in his left wrist generated pain that the ability converted into sustenance. He was, in a grotesque way, running on his own suffering. A perpetual motion machine powered by injury.

The first Grey-Class was a Tunnel Mite—blind, the size of a large dog, all mandibles and segmented legs. It lunged from a crack in the wall and latched onto Jin's already-burned forearm.

The bite was deep. The mandibles punched through damaged tissue and hit bone. Jin's vision whited out for half a second, and Pain Drinker responded with a conversion surge that flooded his system with restored HP. He grabbed the Mite's head with his free hand and twisted until the chitin cracked.

The body dropped. The bite wound sealed over—not fully healed, but closed enough to stop the bleeding.

Behind him, someone gagged. One of the Forgotten members who'd never seen him fight. Never watched the wrongness of it up close—a man walking into damage like it was a warm shower, bleeding and healing in the same breath, treating mortal wounds as fuel.

"Keep moving," Sung-joon said to the group. Steady. Professional. Only his grip on the tablet betrayed him, knuckles white against the screen.

More Mites came. Jin killed them in a haze of pain and conversion, each fight restoring a bit more of what Do-yun had burned away. His body was a patchwork—new skin growing over burns, bruises fading under fresh bruises, the cellular reconstruction happening in real-time in ways that made biological sense only if you read the physics backward.

He'd cleared maybe two hundred meters of tunnel when he found Kim Jae-min.

The kid had fallen behind the main group. He was pressed against the tunnel wall in a gap between support beams, his arms wrapped around his knees, his body shaking in the particular rhythm of someone who was trying very hard not to make noise while also failing at it.

His sound-mimic ability was misfiring. Fragments of noise leaked from his mouth without his permission—a car horn, half a sentence in a woman's voice, the crack of Do-yun's fire against the warehouse wall, all played at random volumes that bounced off the tunnel walls.

Jin stopped walking.

For a long moment, neither of them moved. The rest of the Forgotten continued ahead, unaware, their shuffling footsteps fading around the next bend. A dead Tunnel Mite lay between Jin and Jae-min, its mandibles still twitching.

"They have my sister," Jae-min said.

No preamble. No excuse. Just the words, dropped into the darkness like stones into water.

"Her name is Jae-eun. She's fourteen." His voice was thin, the words tumbling out between involuntary sound bursts—a door slamming, a snippet of a pop song, the screech of subway brakes. "The Iron Wolves picked her up three months ago. Before I even joined you. They said—they said if I didn't tell them where the Forgotten were meeting, they'd register her as a defective. Force-awaken her. You know what happens to force-awakened kids."

Jin knew. The survival rate for forced awakenings in minors was around thirty percent. The ones who survived usually came out damaged—glitched abilities, chronic pain, psychological breaks that never fully healed. The Association officially condemned the practice. Unofficially, the black market for forced-awakening services thrived.

"I didn't want to," Jae-min said. He was crying. The tears caught the faint glow of residual dimensional energy in the tunnel, tracing wet lines down a face too young for the guilt it carried. "I kept thinking, maybe this time they'll let her go. Every time I gave them something, they said, 'One more. Just one more location.' And every time I believed them because I had to, because if I stopped believing them then my sister was—"

His ability misfired again. Do-yun's voice, played back at full volume: *"Your little friend Jae-min says hello."*

The echo rolled down the tunnel. Jae-min flinched like he'd been slapped.

Jin sat down on the tunnel floor across from him. The concrete was cold and wet and his burns protested the contact, and Pain Drinker ate the protest, and the whole stupid cycle continued. He was so tired. Not the physical kind—the kind that sleep, even if it didn't drain him, would never fix.

"Three months," Jin said.

"Y-yeah."

"The Hapjeong raid. The Yongsan supply cache. The meeting point in Gwangjin."

Jae-min nodded to each one. Each nod was a confession that cost him something visible—his shoulders curling inward a little more, his frame shrinking, as if the admission was physically compressing him.

"Park Dae-sung," Jin said. "The man they captured at the peace offer ambush."

Jae-min's face collapsed. "I didn't know they'd take anyone. They said—they said they just wanted to scare you. Show you the Association was serious. I didn't know—"

"Dae-sung had a wife. She died in the First Gate Break, but he had a photograph he kept in his jacket pocket. He showed it to everyone, even if they'd already seen it fifty times." Jin didn't raise his voice. Didn't need to. "He's in a cell somewhere, if he's still alive. Because you made a phone call."

Jae-min's mouth opened and a sound came out—not his, not anyone's—a raw, broken noise that his ability generated from whatever emotional frequency he was broadcasting. It filled the tunnel for three seconds, a wail that wasn't quite human, and then cut off.

"I know," Jae-min whispered. "I know what I did."

Jin looked at the kid. Twenty-two years old. An ability he couldn't control. A sister he couldn't protect. Faced with an impossible choice—betray the only people who'd accepted him, or condemn a fourteen-year-old to a forced awakening that might kill her.

The anger was there. Jin could feel it in the place where his scar lived, a heat that had nothing to do with Pain Drinker. Dae-sung. The Hapjeong raid. The four dead Forgotten members whose names he carried like pebbles in his shoes.

But the anger sat next to something else. Something that looked a lot like recognition.

Because six months ago, before the Forgotten, before any of this, Jin had been a defective in a goshiwon room with no future and no friends and no reason to believe that his life would ever matter. If someone had come to him then and said, *Betray these strangers or watch someone you love suffer*—

He wasn't sure he would have chosen differently.

"Get up," Jin said.

Jae-min looked at him.

"We're not done moving. Get up. Stay with the group. Don't talk to anyone about this."

"What are you going to—"

"I don't know yet." The honesty surprised them both. "Your sister is leverage. If I kick you out, the Iron Wolves keep her and they've lost their inside man, which means they have no reason to keep her safe. If you stay, I can't trust anything you say. Both options are garbage." Jin stood, his knees cracking, his burns pulling. "So we're going to find a third option. But not tonight. Tonight, we survive. Get up."

Jae-min got up. His legs barely held him. A fragment of someone else's laughter spilled from his lips—a woman's laugh, bright and careless, from some conversation his ability had recorded days or weeks ago. The sound was so wrong in this context that it hit like a slap.

They walked. Jae-min's shoulders shook the entire way. Jin's didn't, but only because the burns had stiffened the muscles too much for involuntary movement.

---

The drainage canal exit opened onto a concrete embankment along the Yongsan riverfront at 4:17 AM.

Thirty people spilled out of the tunnel in various states of terror, exhaustion, and injury. Baek Yuri had caught a Mite bite on her calf during the last stretch—Won-shik had stomped the creature to death with a construction boot while everyone else was too panicked to act. Two children clung to their mothers. An older man Jin knew only as "Uncle" sat on the embankment and stared at the river with the empty expression of someone whose capacity for new experiences had been fully overdrawn.

Sung-joon did a headcount. Thirty-one out, thirty-one accounted for. No one left behind. No one lost.

Min-ji moved through the group with a first-aid kit and an efficiency that turned triage into a kind of choreography. She reached Jin last.

"Sit down."

"I'm fine."

"Your left ear is partially detached, your burn coverage exceeds forty percent, and you're standing in a posture that suggests at least two cracked ribs. Would you like to revise your assessment?"

Jin sat.

She worked in silence, cleaning what she could clean, bandaging what she could bandage, carefully avoiding any use of her healing ability. The gauze stuck to his burns and every tug pulled a fresh thread of pain that Pain Drinker quietly consumed. It was the closest thing to intimacy they'd shared in weeks—her hands on his damaged body, treating him with the one skill that was useless on him, substituting basic first aid for the ability that would have healed anyone else in minutes.

"The inverse pulse," she said, wrapping his forearm. "When your HP hit zero. What was that?"

"I don't know."

"Has it happened before?"

"No." Jin watched her work. Precise. Careful. Hands steady again, the earlier crack sealed over with professional focus. "My HP hit zero and instead of dying, my inverse energy went outward. Like a—I don't know. Like a bubble."

"Inverted the local physics within its radius?"

"For about a third of a second, yeah."

"That's not Pain Drinker. That's something else." She tied off the bandage. Her fingers lingered on his wrist for a moment longer than the dressing required. "Something new."

"Something I can't control."

"Yet." She released his wrist and sat back. "I want to run tests. When we're somewhere stable. If we're ever somewhere stable again."

"I'll pencil you in."

The faintest trace of a smile crossed her face. Gone before it fully formed, but there.

Jin looked back toward the tunnel entrance, then south across the river where Mapo-gu's skyline was a dark silhouette against a sky just beginning to think about dawn. Somewhere in those streets, Hwang Do-yun was searching for a trail. The Iron Wolves had lost their quarry tonight, but not their appetite.

They would come again. Soon. With better preparation and worse intentions.

And somewhere in their custody, a fourteen-year-old girl named Kim Jae-eun was waiting for a brother who couldn't save her by himself.

Jin closed his eyes. Pain Drinker hummed along his nerve endings, converting the last of his burns into a warmth that was almost comfortable. His body was healing. His situation was not.

**[EXPERIENCE ACCUMULATED: 1,847 XP]**

**[LEVEL DESCENT: -22 → -23]**

**[PAIN DRINKER: LEVEL 4 → LEVEL 5 (CONVERSION RATE +8%)]**

Level -23. Stronger. Closer to whatever waited at -25.

Two levels away from Curse Eater, and he didn't even know what that meant yet. The System's descriptions were always written for ascending levels—*unlock new ability, gain power, grow stronger*. For Jin, every milestone was a descent. A going-down instead of going-up. A falling that looked like flying if you squinted hard enough.

He opened his eyes. Dawn was starting, pale and gray, turning the river the color of old steel.

Beside him, Jae-min sat apart from the group, hugging his knees, his lips moving silently. No one had spoken to him. No one knew to.

Jin watched him for a long moment, then looked away.

Thirty-one people. One traitor who was also a victim. Zero safe houses.

He pressed his thumb into the scar on his chest and started thinking about third options.
