Garrett found him work on the docks.
Not the real docks — the Tier 4 commercial port where registered freight companies moved dungeon-sourced materials through customs and into the supply chain. The other docks. The unofficial ones along the Tier 5 canal, where barges carried construction debris and recycled monster parts and whatever else the legitimate economy didn't want to touch. The pay was fourteen credits per six-hour shift, no insurance, no contract, and a supervisor named Cho who communicated exclusively through hand gestures and profanity.
Shin carried crates of ground golem stone from barge to truck for six hours. His ribs made their opinion known on every lift. The left side — the side that the Ashburn golem had punched, that had been healing and re-breaking in cycles since Hollowfield — sent specific, articulate messages of protest with each forty-pound crate. He ignored them. He'd been ignoring that rib for weeks, and the rib had accepted this arrangement with the sullen tolerance of a subordinate who'd filed complaints that nobody read.
Fourteen credits. Plus the nine he already had. Twenty-three. Enough for four days of food if he ate like a porter, which was to say barely.
The bus to Block 7 smelled like diesel and someone's fish lunch. Shin sat in the back, hands on his knees, and watched Tier 5 scroll past the scratched window. Pawn shops. Noodle stands. A clinic with a line out the door. Two kids fighting over a ball in an alley, their argument conducted in the high-pitched tactical language of children who'd learned early that volume was a resource.
The calibration disc sat dead in his pocket. He'd tried it three times since the Foundry — held it near mana sources, turned it in sunlight, even brought it close to the broken sword on the theory that residual enchantment energy might trigger something. Nothing. The disc was dark metal and cold weight, a spent battery that had shown him one image and shut down.
A wireframe body. Mana pathways. The structural weaknesses of a humanoid form.
One image. Enough to change how he fought. Not enough to explain why Sato had waited twenty years to hand it to him, or what his mother had been doing with 847 shadow experience in a world that apparently hunted Level 0s, or who "they" were.
Sato hadn't spoken to him since. Two mornings of passing the plastic chair on his way out, two mornings of the old man reading his newspaper or staring at nothing with the cultivated emptiness of someone who'd said what he could say and wouldn't be pushed further. Shin had tried once — "The disc is dead" — and Sato had turned a page and said, "Things are dead until they're not."
Helpful.
The bus dropped him at Block 7 and he walked to the barracks. Changed his shirt. Ate cold rice from yesterday's container. Taped his ribs with the medical tape he'd bought three days ago, wrapping the left side in overlapping strips that compressed the damaged area and turned breathing from a sharp negotiation into a dull one.
He slept from 5 PM to 10 PM. Five hours. Not enough. But enough.
At 10:15, he was over the Tier 5 wall, crossing the waste zone, heading northwest toward a factory that had been dead for thirty years and the thing beneath it that was very much alive.
---
The second night in the Foundry started with a mistake.
Shin dropped through the entrance shaft — fifteen feet, crystal platform, the jar of impact — and moved into the first corridor on autopilot. Same route as last time. Corridor one, left at the junction, corridor three where he'd found two constructs on patrol.
The constructs weren't in corridor three. They were in corridor one. Both of them. Standing in the amber dark twenty feet from the entrance shaft, their featureless heads oriented toward the exact spot where he'd landed.
Null Presence held. The constructs didn't react. But they'd moved. They'd changed their patrol route, positioned themselves near the entrance, adopted a formation that any military tactician would recognize as an ambush posture — two units flanking an access point, waiting.
They weren't waiting for him. They couldn't detect him. But their dungeon core had registered his previous intrusion through the entrance shaft and adjusted the construct patrols to cover it. The dungeon was learning.
Shin pressed flat against the corridor wall and reassessed. The two constructs stood motionless, chest-cores pulsing in synchronized rhythm. Standard C+-rank humanoids — five feet tall, amber crystal, ball-and-socket joints. He could take them one at a time with the lumbar-strike technique. But not two. Not in a corridor this narrow, where a missed strike on the first would alert the second before he could reset.
He circled. The Foundry's grid layout gave him options — parallel corridors connected by cross-junctions, allowing him to approach from the side rather than the front. He took corridor two, moved laterally, and came up behind the pair from their right flank.
The first construct died clean. Lumbar strike — the broken sword's jagged tip punched through the thin crystal of the lower back, fractures spreading, the construct staggering forward as its structural integrity collapsed. Circle to front. Chest thrust. The blade scraped through weakened amber and found the core. Dark. Down.
The second construct turned at the sound of its partner's collapse. Fast. Faster than the ones he'd fought last night — this one's crystal was darker, denser, and it moved with a fluid urgency that the others hadn't shown. Its fist was already swinging before Shin had pulled the blade free.
He ducked. The fist passed over his head, clipping his hair, and the construct's follow-through carried it into a half-rotation that opened its back to him for maybe a second.
Not enough time for a clean lumbar strike. He stabbed anyway — a shallow hit, the worn tip skating across the crystal surface before catching in a seam where two segments joined. The blade bit an inch deep. Not a kill shot. A wound.
The construct spun again. This time the fist caught his forearm — not full force, a glancing impact, but crystal on skin was crystal on skin and the pain was immediate and comprehensive. His grip weakened. The sword almost dropped.
He backpedaled into corridor two. The construct followed, its damaged back leaking amber dust, its movements slightly off-kilter from the shallow stab. Shin watched it approach and noticed something: the construct was limping. Not dramatically — a subtle hitch in its right leg's extension, a compensation pattern in its gait. The lumbar damage had compromised its hip joint on one side.
The construct charged. Shin went low and right — toward the compromised leg — and the construct's swing missed wide as its damaged hip failed to rotate fast enough. He drove the sword into the back of its right knee joint, where crystal met organic connective tissue, and twisted.
The leg buckled. The construct went down on one knee. Its arms still worked — a backhand sweep forced Shin to jump backward — but its mobility was gone. It knelt in the corridor, swinging, a crippled sentry defending a position it could no longer leave.
Shin waited. Circled to its blind side. The construct's head tracked left, tracking vibrations through the floor, and its arm swept in that direction. Shin stepped right. Drove the blade into the lower back, through the fracture pattern from the first strike, and this time the tip reached deep enough to compromise the chest cavity from behind.
The construct slumped. Core dark. Down.
**[Shadow Experience: 586.3/1,000]**
Eighteen per kill. Thirty-six total. He was breathing hard, and the forearm where the fist had connected was already swelling.
Shin leaned against the corridor wall and examined the sword. The jagged tip — his killing edge, the sharp point that the break had created — was visibly shorter. Each thrust against crystal wore it down, rounding the sharp angles, dulling the penetrating edge. Last night the tip had been almost needle-like. Now it was blunted, the point spread into a wider profile that would need more force to achieve the same penetration depth.
He had maybe fifteen more kills before the tip was too dull to punch through crystal at all. Maybe fewer, depending on the thickness of the targets.
Fifteen kills. Two hundred seventy shadow experience. That would put him at 856.
856.
Nine more than his mother.
---
The hours between midnight and 4 AM became a routine that had the shape of a ritual and the texture of a beating.
Kill three was in corridor six. A construct with disproportionately long arms — its reach exceeded Shin's by two feet, forcing him to bait a swing before he could close distance. The lumbar strike landed clean, but the chest thrust was shallow. The construct died slowly, its core dimming in stages rather than winking out, and the final dark took eight seconds of Shin holding the blade in place while the construct's arms twitched and its fingers opened and closed around nothing.
Kill four was in corridor nine, deeper than he'd gone before. The crystal here was older, the amber darker, and the construct was different — shorter, stockier, with crystal armor that was thick enough to be nearly opaque. The lumbar strike bounced. The tip skated across the surface without catching, and Shin had to find an alternate entry point — the armpit, where the arm socket created a gap in the crystal shell. He drove the blade upward through the gap, angled toward the chest core, and the construct died on its feet, toppling forward like a tree cut at the base.
That kill cost him a gash on his left hand. The construct's elbow had caught him during the armpit approach, crystal edge slicing the web of skin between his thumb and forefinger. Not deep. Deep enough to bleed steadily, making the sword grip slick.
He wrapped the hand with a strip torn from his shirt tail and kept going.
Kill five. Corridor twelve. Standard construct, standard technique, clean kill. The sword tip was noticeably duller.
**[Shadow Experience: 622.3/1,000]**
Kill six. Corridor twelve, second construct. This one was patrolling with a gait that was subtly different — slower, more deliberate, its head tracking not in sweeps but in focused stares at specific points in the corridor. As if it was looking for something. As if it had been told to look.
The lumbar strike landed. The construct staggered. Shin circled to the front and thrust for the chest—
The construct caught the blade.
Its left hand closed around the broken sword's shaft, crystal fingers gripping steel, and held. The sword was immobilized. Shin pulled. The construct pulled back. For one absurd second they stood in the amber corridor engaged in a tug-of-war over ten inches of broken steel, and then the construct's right fist came around in a hook that Shin saw too late.
The hit caught him in the ribs. Left side. The taped side. The side that had been cracked and healed and cracked again so many times that the bone was probably more scar tissue than calcium.
The pain was white. Not sharp — white, the color of a noise too loud to have a frequency, filling his entire torso with a single undifferentiated signal that erased everything else. He lost the sword. Lost his footing. Hit the corridor floor on his back and slid two feet on the smooth crystal surface.
The construct stood over him, the broken sword still in its left hand, its right fist raised for a follow-up. The chest core pulsed behind fractured amber.
Shin kicked. Both feet, up and forward, into the construct's damaged lower back. The fractured crystal gave way — chunks separating, falling, the construct's midsection collapsing as the structural damage from the lumbar strike finally exceeded the body's tolerance. The construct folded at the waist. Its torso hinged backward, the spine-equivalent snapping, and it crashed to the floor in two pieces.
The chest core was still lit. The upper body was still moving — one arm pulling the torso forward in a crawl, the other still gripping the sword. A half-dead thing dragging itself toward the vibrations of a prone human with the blind persistence of a machine that hadn't received the command to stop.
Shin grabbed a chunk of broken crystal from the floor. Fist-sized. Dense. He drove it into the construct's chest core like a hammer hitting a nail.
The core cracked. Dimmed. Dark.
Shin lay on the crystal floor for two minutes, holding his ribs and breathing in the shallow, careful sips of someone negotiating with damaged infrastructure. The white pain faded to gray, then to red, then to the familiar sharp ache that he'd been carrying for weeks. Nothing new was broken. The tape had held. But the ribs had taken another impact, and the cumulative damage was building toward something that first aid couldn't address.
He retrieved the sword from the dead construct's grip. The tip was worse. The impact against crystal fingers had chipped the edge further, and the point was now more wedge than needle. He tested it against his thumbnail — dull. A dull blade that needed to punch through an inch of crystal.
Twelve more kills. Maybe ten, if the tip degraded this fast.
He ate half a ration bar — his second-to-last — and kept going.
---
The Foundry had a geography that Shin was starting to map in his head.
The upper corridors — one through ten — held standard constructs. Five-foot humanoids, C+-rank, eighteen experience each. They patrolled in singles or pairs, following routes that covered the corridor grid in overlapping patterns. The dungeon core rotated their routes between sessions, but the overall density was consistent: roughly two constructs per three corridors.
Below the upper grid, a ramp descended to a lower level. The crystal here was denser, the amber darker, and the corridors were wider — ten feet instead of eight. Shin had explored the top of the ramp on night one but hadn't descended. The mana concentration increased sharply at the transition, and the constructs he could see through the translucent crystal walls were bigger.
He wasn't ready for bigger. Not with a dying sword and ribs held together with tape.
But between the upper grid and the lower ramp, in a transitional zone where the corridor layout shifted from tight grid to broader passages, there were alcoves. Carved into the crystal walls — or grown into them, it was hard to tell — with concave surfaces that formed natural seats. Rest points. Whether the dungeon had created them for its constructs or they were an accident of crystal growth, they served as spaces where Shin could sit, eat, and assess without being in a patrol path.
He found one in corridor fourteen, deep in the transitional zone, and settled in. The crystal was warm against his back. The amber light pulsed with the slow rhythm of something breathing.
622.3 out of 1,000. Sixty-two percent. When he'd entered Hollowfield for the first time — a number that felt like it belonged to a different person in a different century — he'd been at zero. Now he was closer to Level 1 than to the start.
And his mother had reached 847.
He turned the number over. 847 out of 1,000. Eighty-four percent. She'd been deep into the grind, further than Shin was now, close enough to the end that the remaining distance must have felt like a held breath. And then they'd found her. Whoever they were. And she'd—
What? Died? Been captured? Sato hadn't said. "They found her" could mean anything from arrest to execution, and Sato's refusal to elaborate was either protection or cruelty, and Shin couldn't tell which.
She'd used the same phrase. "I've been called worse." Said it with the same flatness, probably. The same dead-eyed dismissal of insults that Shin used like armor, that he'd thought was his own invention, a survival tool he'd forged in Tier 5's furnace. But it was hers first. She'd developed it, used it, passed it down through genetics or proximity or whatever mechanism turned a mother's coping strategy into a son's reflex.
He hadn't known her. Didn't remember her. The orphanage records listed his mother as "deceased, no further information," which was the bureaucratic equivalent of a shrug. Twenty years of shrugs, and then an old man in a plastic chair tells you she was the first Level 0, that she got further than you have, that someone stopped her.
Shin pressed his back against the warm crystal and made a calculation that had nothing to do with experience points.
If she'd reached 847 and been stopped, there was a boundary. A tripwire. Some mechanism — System-based, institutional, or human — that detected a Level 0 approaching the threshold and triggered a response. And that mechanism might still be active. Might be watching the same indicators now that it watched thirty-one years ago. Might already be aware that a second Level 0 was grinding in a secret dungeon, climbing toward the number that had gotten the first one killed.
847 wasn't just a milestone. It was a warning.
Shin filed this and stood up. The rib complained. He overruled it.
Two more kills, then he'd climb out and catch the 5 AM bus. Tomorrow was another dock shift. Fourteen credits. Cold rice. Tape and ration bars and the slow accumulation of damage on a body that couldn't afford to be damaged.
He moved into corridor fifteen. Deeper into the transitional zone, where the passages widened and the crystal formations grew thicker and the ambient mana made his sinuses ache.
Corridor fifteen was empty. No construct patrols. The floor was smooth crystal, the walls clean amber, the ceiling a uniform nine feet. Standard Foundry architecture.
Except for the wall.
Shin stopped. Looked left.
The left wall of corridor fifteen, about chest height, bore marks. Not natural marks — not crystal growth patterns or stress fractures or the organic seams where segments joined. These were linear. Parallel. Evenly spaced. Cut into the crystal surface with something harder than fingernails and more precise than monster claws.
Tool marks.
Shin stepped closer. Ran his finger along one of the grooves. The cut was clean — sharp-edged, approximately two millimeters deep, made with a blade or chisel held at a consistent angle. The crystal inside the groove was lighter than the surrounding surface, the fresh-cut amber not yet darkened by exposure to the dungeon's mana-saturated air.
Fresh. Days old. Maybe less.
He counted the marks. Seven parallel lines, about two inches apart, running horizontally across a section of wall approximately eighteen inches wide. Below them, a second set — four lines, shorter, at a different angle. And below that, something that wasn't lines at all but a symbol. A rough shape scratched into the crystal with deliberate strokes.
A triangle. Open at the top. With a horizontal line through its center.
Shin didn't recognize the symbol. It wasn't System notation or Bureau coding or any guild marker he'd seen in his years of carrying equipment through dungeon staging areas. It was crude — made quickly, with a tool that wasn't designed for precision carving — but intentional. Someone had come to this corridor, this specific wall, and left a mark that meant something.
He checked the floor. Scuffed. Faint marks in the crystal dust — not footprints, the dungeon's surface was too hard for impressions, but disturbance patterns. Someone had stood here. Shifted their weight. Knelt, maybe, given the height of the lowest markings.
He checked the adjacent corridors. Fifteen was clean except for the marks. Fourteen — his rest alcove — showed nothing. Sixteen, further into the transitional zone, had—
More marks. Different wall. Same tool. This time just three lines, with a small circle scratched beneath them. A notation. A counting system, maybe. Or waypoints. Someone was marking a route through the Foundry, leaving signs that only someone looking for them would find.
Shin stood in corridor sixteen, in the amber dark, holding his dying sword, and processed the information with the cold efficiency of someone who'd survived twenty years by never assuming he was alone.
The Foundry was not his secret.
Someone else had been here. Recently. With tools and intent and a marking system that suggested not a single visit but a repeated pattern — a person or persons who knew the dungeon existed, who navigated its corridors, who left breadcrumbs in crystal that said I was here and I'll be back.
The scratches were chest-height for an average adult. The tool marks suggested a rigid blade — a chisel or knife, not a sword. The symbol was unfamiliar, which meant it was either personal notation or organizational code from a group Shin didn't know.
He thought about the disc. The map it had shown — mana channels converging on this point, a concentration that the city's sensors didn't reach. Sato had given him the disc and said it had been waiting for twenty years. If Sato knew about the Foundry, others could too. The same mana channels that the disc had tracked were physical features of the earth, detectable by anyone with the right equipment.
And the disc itself — who had made it? For him, Sato said. Specifically for him. That meant an organization. A group with the resources to create calibration technology and the foreknowledge to prepare it for a Level 0 who hadn't been born yet. A group that might also know about a secret dungeon growing beneath an abandoned foundry in the waste zone.
A group that might use a triangle with a line through it as their marker.
Shin memorized the locations. Corridor fifteen, left wall, seven lines and a symbol. Corridor sixteen, right wall, three lines and a circle. He'd check for more on subsequent visits — map the markings, track the pattern, determine whether the marks were old reconnaissance or active monitoring.
For now, the calculations changed. The Foundry wasn't a safe haven. It was a workspace that someone else had claimed first, or at least surveyed first, and Shin was grinding in their territory without knowing the terms.
He climbed out. The waste zone was cold. The wall was cold. The bus was late.
He sat in the back and held the dead disc in one hand and the dying sword in the other and stared at the window where Tier 5 was waking up in the gray light of another morning that didn't care about his math.
640.3 out of 1,000. Four more kills tonight. Seventy-two experience gained across two sessions in the Foundry. At this rate — four kills per night, eighteen per kill — he'd pass his mother's 847 in four more sessions.
If the Foundry was still his in four sessions.
If whoever made those marks didn't come back first.
The triangle with the line through it. Seven parallel marks. Fresh crystal dust in corridors that were supposed to be secret.
Shin closed his eyes. He didn't sleep.
