Chapter 21: Level -100

The System threw everything at him.

Jin descended through tunnels that had become war zones. Creatures emerged from every surface—not random spawns, but coordinated attacks orchestrated by an intelligence that controlled the very fabric of reality. Wave after wave of monsters, each stronger than the last, each designed to exploit weaknesses that the System had been cataloging since his awakening.

He killed them all.

Pain Drinker converted their attacks into healing. Curse Eater devoured their debuffs. Inverse Domain turned their coordinated strikes into opportunities for growth. And with each kill, his level dropped.

**[LEVEL: -99]**

The notification seemed to mock him. One level from the milestone that would change everything. One death from the threshold that even the System feared.

The next wave was different.

They weren't monsters—they were hunters. Association elites, the best the Council could deploy, teleported directly into the Deep Underground through gate manipulation that must have cost enormous resources. Twenty of them, their levels ranging from 300 to 500, their abilities covering every combat specialty the System recognized.

"Jin Seong-ho." The leader stepped forward—a woman Jin didn't recognize, Level 478, with the cold eyes of someone who'd killed more than she could count. "By order of the World Hunter Council, you are sentenced to immediate termination. Do you have any last words?"

Jin laughed.

The sound echoed off the ancient walls, carrying a quality that made several hunters step back involuntarily.

"Last words?" He spread his arms, inviting attack. "How about these: thank you for coming."

They attacked as one. Twenty coordinated strikes, each designed to exploit a different vulnerability, each carrying enough power to destroy city blocks.

Jin absorbed it all.

The pain was extraordinary—twenty sources of damage crashing into his inverse nature simultaneously, Pain Drinker struggling to convert the sheer volume of incoming force. His HP dropped precipitously, then surged back as the conversion process caught up. His body was torn apart and rebuilt in cycles too fast to perceive.

And his level dropped.

**[DAMAGE RECEIVED: 47,892 HP]**

**[PAIN DRINKER ACTIVATED]**

**[HEALING APPLIED: 71,838 HP]**

**[LEVEL ADJUSTMENT: -99 → -100]**

**[MILESTONE REACHED: LEVEL -100]**

**[NEW ABILITY UNLOCKED: DEATH WALKER]**

The notification came with a surge of power unlike anything Jin had experienced. The world seemed to pause, reality holding its breath as his nature evolved to incorporate the new milestone.

**[DEATH WALKER: Death is no longer a terminal state. When HP reaches zero, consciousness transfers to the inverse dimension. Return to physical existence at will. Each death increases base stats by 5%. No limit.]**

Jin processed the ability's implications through a haze of ongoing combat. He couldn't die. Not in any meaningful sense. Death had become a power source, a transformation mechanism, a door to somewhere else rather than an ending.

The hunters were still attacking, but their strikes felt different now. Less urgent. Less threatening. Jin could see their assault patterns with perfect clarity, predict their movements before they began, understand their abilities better than they understood themselves.

This was what Level -100 meant. This was why the System had been so desperate to stop him before he reached it.

"Enough." Jin spoke the word quietly, but it carried weight that made the air vibrate.

He activated Inverse Domain at full power, stretching it to encompass every hunter in the chamber. Within that space, their abilities inverted. Healing became damage. Strength became weakness. Their carefully coordinated attack became chaos as each member of the team found their powers working against them.

"What—what is this?" The leader stumbled backward, her Level 478 suddenly feeling like a liability rather than an asset. "What have you done?"

"I've shown you what I really am." Jin walked through the domain, untouched by the flailing attacks of hunters whose abilities had turned traitor. "You came here to kill an anomaly. You found something else entirely."

He reached the leader and placed a hand on her shoulder. She flinched, expecting death, expecting some terrible application of his inverse power.

Instead, Jin simply held her in place.

"Go back," he said. "Tell the Council what you witnessed. Tell them that Level -100 is just the beginning. Tell them that every weapon they send makes me stronger, every attack pushes me further down the path they want to prevent."

"They'll never stop hunting you."

"I know." Jin released her and stepped back. "But they should understand what they're hunting. Not a threat to be eliminated, but an inevitability to be accepted. I'm going to reach Level -999 whether they try to stop me or not. The only question is how much damage they cause along the way."

He deactivated the Inverse Domain, letting the hunters' abilities return to normal. They stood frozen, not from any power of his, but from shock at what they'd experienced.

"Run," Jin said. "While you still can."

They ran.

---

The path beyond -100 was different.

Jin descended through regions that no longer resembled tunnels or caverns. The prison's architecture became more apparent with each level lost—walls that weren't walls, spaces that defied conventional geometry, energies that pulsed with purpose.

He was no longer traveling through earth. He was traveling through the prison itself—moving along pathways the containment structure had created, following routes that led toward its heart.

**[LEVEL: -100 → -105]**

**[LEVEL: -105 → -112]**

**[LEVEL: -112 → -124]**

The descent accelerated. Creatures continued to attack, but they were less coordinated now, more desperate. The System's control weakened as Jin moved deeper into territory that existed at the edge of its reach.

And then he encountered the Warden again.

The entity materialized from dimensions that shouldn't have intersected with physical space—that same presence of absence, that hole in existence that defied description.

"Key." The voice surrounded him. "You have passed the threshold we were designed to prevent."

"I have." Jin didn't slow his pace, continuing to move deeper even as the Warden manifested around him. "And I'm not stopping."

"Our nature has been reassessed. Our purpose remains unchanged, but our methods must adapt." The Warden's presence intensified, pressing against Jin from every direction. "Direct confrontation failed. Psychological manipulation failed. The siege failed. The hunter deployment failed."

"You're running out of options."

"We have one option remaining." The Warden's voice flattened—resignation bleeding through. "Integration."

Jin stopped walking. "What does that mean?"

"We are the prison's final defense. We exist to prevent keys from reaching the heart. But our existence is tied to the prison itself—we are as much a part of its architecture as the walls and pathways you have been traversing."

"You're going to merge with the prison? Make it stronger?"

"No. We are going to merge with you."

The attack came without warning—not a physical assault, but an existential one. The Warden's presence began to flow into Jin, trying to integrate with his inverse nature, trying to become part of him in a way that would allow it to control his descent from within.

Jin felt the invasion as a cold pressure in his consciousness. The Warden's intelligence, its purpose, its ten-thousand-year dedication to preventing exactly what Jin was trying to accomplish—all of it was trying to become part of him.

"This is our final strategy." The Warden's voice was inside him now, speaking from a place that Jin couldn't isolate or reject. "We cannot destroy you. We cannot stop you. But we can become you. And once we are integrated, your descent becomes our descent. Your choices become our choices."

"You're going to ride along? Watch from inside while I reach -999?"

"We are going to redirect you. Guide you away from the Creator. Lead you to dead ends and false paths while convincing you that you are making progress." The Warden's presence spread through Jin's mind like frost across glass. "You will descend forever, never reaching your destination, never understanding why."

Jin felt the trap closing around his consciousness. The Warden was ancient, experienced, designed specifically for this purpose. Its integration was flawless—finding cracks in his mental architecture that Jin hadn't known existed, filling them with influence that felt like his own thoughts.

For a moment, he believed it would work. Believed that the Warden would succeed where everything else had failed.

Then he remembered what the Bridge had taught him.

*Your consciousness contains multitudes. If you can learn to invert your own awareness—to turn your perception inside out—you can access states of being that even the Warden cannot reach.*

Jin hadn't fully understood those words when he'd first heard them. Now, with the Warden inside his mind, trying to control him from within, the meaning became clear.

He couldn't fight the Warden's integration. But he could invert it.

Jin turned his consciousness inside out.

The sensation was beyond description—like being everywhere and nowhere simultaneously, like existing as both observer and observed, like becoming the space between thoughts rather than the thoughts themselves.

And the Warden, which had integrated with his normal consciousness, found itself suddenly on the wrong side of reality.

"What—what have you done?" The entity's voice carried confusion for the first time. "We were inside you. We were part of your awareness—"

"You were part of my awareness." Jin's inverted consciousness looked at the Warden from an angle that shouldn't have existed. "But I have more than one awareness. I have the inverse of my awareness. And you integrated with the wrong one."

"That's not—that's impossible—"

"Everything about me is impossible." Jin began to reassert his normal consciousness, leaving the Warden trapped in the inverted space he'd created. "You tried to become part of me. Now you're stuck in a part of me that doesn't connect to anything useful."

"We will escape. We will find a way out—"

"Maybe. But by then, I'll be at Level -999, and none of this will matter."

Jin resumed his descent, leaving the Warden screaming in an inverted prison within his own consciousness.

The final defense had failed.
