The B-rank Tunneler had dug itself a nest sixty feet below street level.
Raze found the entrance where Kira had indicated — a service shaft that led to abandoned subway maintenance tunnels, which led to a natural cave system that shouldn't have existed beneath a major metropolitan area. The dungeon breaks were reshaping the city's underground geography, creating new spaces where reality bent to accommodate things that didn't belong in the human world.
He descended in darkness, Darkvision rendering the lightless tunnels in perfect clarity. The air grew warmer as he went deeper, thick with the mineral smell of fresh-carved rock and something else underneath — the organic musk of a creature that had claimed this space.
The Tunneler's mana trail was obvious to his enhanced senses. A residue of displaced earth-affinity power, marking the walls where the creature had passed. It glowed faintly in Raze's thermal vision, a warm signature that led him through increasingly narrow passages until the tunnel opened into a chamber the size of a basketball court.
The Tunneler was waiting.
**[THREAT DETECTED: EARTH TUNNELER — VARIANT: SIEGE TYPE]**
**[Rank: B]**
**[Skills: Earthmeld, Tremorsense, Stone Armor, Burrow Strike]**
**[Behavior Note: This variant is semi-sessile. It creates a nest and defends it. It does not pursue targets that retreat.]**
**[Recommendation: Retreat and report to Hunter Response for coordinated assault.]**
The creature was beautiful in the way that efficient killing machines are always beautiful — form following function with absolute precision. Roughly twice the size of the Ironhide Boar, with a body designed for digging: segmented armor plating, massive forelimbs tipped with crystalline claws, a blunt head that could punch through concrete like butter. Its eyes were vestigial, barely visible dots on the armored snout. It navigated by sensing vibrations through the stone.
Which meant it knew exactly where Raze was standing.
The Tunneler didn't charge immediately. It shifted its weight, armor plates grinding against each other, and tracked his position with an awareness that had nothing to do with sight. Raze could feel its attention like pressure against his skin — the predatory focus of something that had killed dozens of creatures in its domain and was calculating whether this intruder was worth the effort.
He was counting on that calculation.
B-rank creatures were intelligent enough to assess threats. They didn't attack blindly — they evaluated, strategized, looked for weaknesses. Which gave Raze time to evaluate in return.
Stone Armor would be the main problem. The Tunneler's plating wasn't just thick; it was actively reinforced with earth mana, harder than anything his current offensive capabilities could punch through. The only vulnerable points were the joints between plates — small gaps that allowed movement but created openings.
Hit the joints. Avoid the burrow strike. Don't let it meld into the stone or he'd lose tracking.
Simple, in theory.
The Tunneler moved.
Not a charge — a sink. Its body dropped into the rock floor like the stone was water, surface rippling as it vanished from sight. Tremorsense would let it track him from below. Burrow Strike would bring it up beneath his feet, claws first, with enough force to bisect a car.
Raze didn't wait for the attack. Shadow Lunge activated, folding him across the chamber to a different position, and he landed on a stone outcropping as the Tunneler erupted where he'd been standing. Crystalline claws tore through the air, trailing rock fragments and frustrated violence.
The creature howled — a subsonic rumble that Raze felt in his bones rather than heard. It sank again, faster this time, and he shadow-stepped again, staying one jump ahead of the burrow strikes.
He couldn't keep this up forever. Shadow Lunge had limited uses per hour, and the Tunneler wasn't tiring. It would eventually catch him, and Stone Armor meant he couldn't hurt it in a straight fight.
But Raze wasn't fighting fair.
He let the next burrow strike come close — closer than comfortable — and activated Iron Skin the moment the claws connected. The impact was staggering, like being hit by a truck wrapped in knives, but his reinforced dermis held. The claws scored lines across his arm rather than removing it entirely.
The Tunneler paused. Its vestigial eyes couldn't see, but its tremorsense could read the feedback from its own claws. It had struck, and its prey hadn't died. That was new information.
In that moment of reassessment, Raze attacked.
Not with hands or weapons — with Pack Command. The skill pulsed outward, carrying the weight of an alpha predator's dominance, and slammed into the Tunneler's consciousness like a hammer. Submit. Recognize superiority. Bow.
The effect on a B-rank creature was different from the Ironhide Boar. The Tunneler didn't collapse into submission. But it flinched, just for a second, its movements stuttering as competing instincts fought for control. Defend territory versus acknowledge dominant predator.
That second was enough.
Raze shadow-stepped to the Tunneler's back, found the gap between armor plates at the base of its skull — every creature had a vulnerable spine — and drove his fingers into the joint with all the strength his consumed cores could provide.
The Tunneler screamed. Not subsonic this time — a full-voiced shriek of pain and rage that echoed through the chamber. It thrashed, trying to shake him loose, and he held on with grip strength that tore his own muscles and healed them in the same motion. His hand found the nerve cluster he was looking for and crushed.
Paralysis spread from the wound. The Tunneler's thrashing weakened, became twitching, became stillness. It collapsed against the chamber floor, armor plates rattling, and its subsonic rumble dropped to something almost pitiful.
Raze climbed off its back, breathing hard. His arms ached. Iron Skin had held, but the force had still transmitted through — bruises were forming beneath the reinforced dermis, and his healing factor was working overtime.
The Tunneler wasn't dead yet. Its eyes — those tiny vestigial dots — seemed to find him somehow. There was something in them that might have been understanding.
"Sorry," Raze murmured, and meant it. He killed to eat, not for pleasure. The hunger didn't care about the suffering of its meals, but he still did. Maybe that was the 85% Human Purity talking.
He snapped the creature's neck and waited for the core to form.

**[SKILL ABSORBED: Earthmeld — Phase through stone and earth for limited periods]**
**[SKILL ABSORBED: Tremorsense — Detect vibrations through solid surfaces within 50 meters]**
**[SKILL ABSORBED: Stone Armor — External plating manifests during combat (WARNING: Visible mutation)]**
**[SKILL COMBINATION DETECTED: Iron Skin + Stone Armor = FORTRESS BODY — Internal and external reinforcement layer. Approaching B-rank physical defense.]**
**[HUMAN PURITY: 85% → 82%]**
Three percent for a B-rank. Higher than ideal, but the skill combination made it worthwhile. Fortress Body would let him tank hits that would have been lethal before. And Earthmeld combined with Shadow Walk opened tactical options he hadn't considered — moving through stone as easily as darkness.
The integration pain was more intense this time. Raze bit through his jacket, tasting leather and blood as his bone structure shifted to accommodate the new density requirements. His skin crawled as the Stone Armor traits wove themselves into his physiology, creating latent armor plates that would manifest only when activated.
When the process finished, he stood in the Tunneler's nest and took inventory.
Sixteen cores consumed. Eighty-two percent Human Purity. Twenty-one skills, with six combinations. He was stronger than any C-rank hunter and could probably match a B-rank in direct combat now, depending on the matchup. His physical abilities were approaching the limits of what could be explained by normal awakening.
The next step was obvious: he needed higher-quality cores. B-rank was his current tier. A-rank would push him further. And somewhere out there, S-rank creatures waited — power sources that could elevate him beyond the hunter classification system entirely.
But getting access to A-rank cores meant getting access to A-rank dungeons. And A-rank dungeons were strictly controlled by the major guilds and government agencies.
He needed an inside track.

Kira's dead drop system was exactly as paranoid as she'd described: physical notes hidden in specific locations, coded messages that required pre-shared context to decode, and absolutely no digital footprint. She'd clearly spent three years assuming the Association was monitoring her communications.
The first note was waiting in a hollow brick behind a convenience store in Hongdae:
**Good hunt? The tunnels should be quiet now. Association already wrote off the Tunneler as "presumed eliminated during break response." You're welcome for the cover.**
**More importantly: I found something. Cross-reference your files if you have any — the name "Director Morrow" comes up in a lot of aberrant disappearances. Hunter Services Internal Security. He's running some kind of quiet program, and nobody knows the full scope except people at his level.**
**I'm digging deeper. Dead drop location two in 48 hours.**
**Stay hungry. K.**
Raze memorized the note and destroyed it, grinding the paper to dust between fingers that could now punch through concrete. Director Morrow. The name meant nothing to him directly, but the pattern Kira was describing — aberrant disappearances, internal security, quiet programs — matched the threat she'd outlined at the café.
The Association wasn't just watching aberrants. They were collecting them.
The question was what for.
He left the convenience store area and headed for his apartment, moving through late-night streets with the easy gait of a predator who knew nothing here could threaten him. It was a dangerous mindset — overconfidence killed more hunters than lack of skill — but the city felt different now. Smaller. Less threatening.
He was growing past it.
His apartment building materialized from the urban darkness, a twelve-story tower of anonymous residences. Raze entered through the service entrance, took the stairs to his floor, and approached his door with the automatic caution of six months of hiding.
The caution saved his life.
His enhanced senses caught the wrongness before he touched the handle — a foreign mana signature inside his apartment, faint but present. Someone had been here. Someone who left traces.
Raze stepped back from the door. His eyes adjusted, shifting to thermal vision, and he scanned through the walls. No heat signatures inside. The intruder was gone.
But they'd left something behind.
He entered carefully, Iron Skin and Stone Armor primed, ready for anything from a trap to an ambush. The apartment looked undisturbed — same sparse furniture, same bare walls, same minimal personal effects. Nothing moved.
On his kitchen counter, where nothing had been when he left, sat a small package wrapped in brown paper.
No note. No identifying marks. Just a box, about the size of a fist, sealed with ordinary tape.
Raze picked it up. Light. Something inside rattled slightly — solid, crystalline. His hunger surged, recognizing the signature before his conscious mind could process it.
A core. Someone had left him a core.
He unwrapped the package with fingers that trembled from something other than fear.
Inside was a monster core he'd never seen before — deep purple, almost black, with swirling patterns that suggested a creature from a dungeon tier he had no business encountering. The mana emanating from it was dense, intoxicating, unlike anything in his experience.
And attached to the core was a small card with handwritten text:
**A gift from an admirer. Eat well, little eater.**
The hunger screamed at him to consume it immediately. To take this power, whatever it was, and add it to his growing arsenal.
But something in the phrasing made him pause. Little eater. The specific word choice. The deliberate delivery.
Someone knew what he was. Someone with access to cores that shouldn't exist outside of high-tier dungeons. Someone who wanted him to eat this particular offering.
Raze looked at the core. The core seemed to pulse in response.
The trap was obvious. The bait was irresistible.
Tomorrow, he'd decide what to do about it. Tonight, he'd sleep with the core locked in a drawer and the hunger howling at the edges of his dreams.
