Shin didn't go to the docks.
He lay on the cot from 6 AM to 4 PM, not sleeping — not really — but in the shallow half-state that his body defaulted to when the damage was too extensive for full unconsciousness and the stakes were too high for full rest. His eyes closed. His breathing was measured. His hands, re-taped with the last of his medical tape, throbbed in time with his heartbeat like a pair of drums playing the same rhythm at different volumes.
Fourteen credits lost. One day's dock wages that wouldn't be earned, that wouldn't buy food or tape or the bus fare for the route he'd need tonight. The math of skipping work was simple and bad: he had nineteen credits left, which was food for two days if he ate porter-grade, and after that the numbers hit zero. But the math of not skipping work was worse — six hours on the docks meant six hours not sleeping, and tonight's session required a body that could function at combat intensity for four hours without collapsing.
At 2 PM, he ate. Everything. Two ration bars, the last of the cold rice, half a packet of instant noodles that he made with hot water from the barracks' shared kettle. The food sat in his stomach like ballast, heavy and purposeful, and his body accepted it with the graceless urgency of a machine being fueled for a final run.
At 3 PM, he inventoried. Four construct cores — his weapons. The dead calibration disc. The broken sword shaft, still in his belt, still useless, still there because throwing it away would mean admitting that something he'd carried for weeks had no purpose, and Shin was not in the business of admitting things were purposeless until they proved it conclusively. Medical tape: gone, the last roll spent on his hands this morning. Ration bars: gone. Credits: nineteen, which he'd need for bus fare.
At 4 PM, he taped his ribs with strips cut from a spare shirt. Not medical tape — cotton fabric, less adhesive, less compression, but better than nothing against a rib cage that was functioning on reputation rather than structural integrity.
At 4:30, Sato's chair was empty. The plastic seat held an impression where the old man's weight had been, and a half-finished cigarette smoked in the ashtray balanced on the armrest, but Sato himself was gone. Shin couldn't remember the last time the chair had been empty during waking hours. Sato lived in that chair the way moss lives on a rock — gradually, permanently, as if the separation of organism from surface would damage both.
The cigarette was still burning. He'd left recently.
Shin filed this and moved on. Sato's absence was either meaningful or coincidental, and he didn't have the bandwidth to determine which. Tonight was six kills. One hundred and eight experience. The only number that mattered.
He slept until 9 PM. Real sleep this time — four and a half hours of deep, dreamless unconsciousness that his body extracted from the available time like a miner extracting ore from a depleted vein. When the alarm on his phone woke him, the barracks was dark, the other porters were asleep or out, and the night was waiting.

The canal culvert. The cold water. The waste zone.
Shin approached the Foundry from the southeast this time — a different angle than last night's eastern approach, threading through a section of the waste zone he hadn't used before. Chemical storage on his left. A collapsed water treatment plant on his right. The footing was treacherous — chemical residue on asphalt that was slick under his boots, rubble from structural failures that appeared in the dark as sudden obstacles.
The disc was cold. Not warm. Not pilot-light. Cold, the way it had been during bus rides through non-mana areas. Whatever the disc's activation had cost it last night, it wasn't recovered. Dead battery. He was on his own.
He reached the factory complex from the rear again. Climbed through the wall collapse. Crossed the connecting buildings.
The main building's entrance — the one with the hanging door — told him things he needed to know.
The concrete doorstop was in a different position. Last night it had propped the door closed from the inside. Now it sat three feet from the door, on the outside, as if someone had exited the building, moved the doorstop out of the way, and not bothered to replace it. The door hung open on its one hinge, swinging slightly in the waste zone's chemical-tinged breeze.
Boot prints in the factory yard. The two sets from before — the tire-track visitors — and a third set. Newer. Different tread pattern. Smaller print, narrower sole. Someone had come here after the first two, alone, on foot rather than by vehicle.
Three visitors in two days. Reconnaissance was escalating. But the building's interior, as Shin moved through it, showed no surveillance equipment. No cameras on the walls. No motion sensors on the doorframes. No electronic monitoring of any kind. The visitors had looked and left. They were still in the observation phase — studying the site, measuring the crystal growth, determining the dungeon's characteristics before committing resources to a full operation.
They hadn't found the entrance shaft yet. The subbasement access — behind the largest furnace, down the crystal-coated stairs — was hidden behind thirty years of crystal growth and industrial debris. A casual inspection of the ground floor wouldn't reveal it. You'd need to be looking for it specifically, or you'd need to follow the crystal density downward, which required either mana-sensing equipment or the kind of obsessive attention to ambient temperature that Shin had developed over weeks of grinding.
He had tonight. Maybe one more night after that, if the reconnaissance team was slow. But probably just tonight.
Six kills. One hundred and eight experience. Then Level 1, and every calculation changed.
Shin descended.
---
Kill one. Corridor two. Standard construct, standard patrol.
The dead-spot technique worked the way muscle memory works — without thought, without hesitation, the body executing a pattern that the conscious mind had delegated to faster processing. Circle behind. Right shoulder. Chisel into the dead spot. Three strikes.
The crystal at the dead spot parted. The chisel sank. Mana sprayed from the severed channel, amber light leaking from the wound. The construct's arm dropped. Its core flickered.
Circle front. Chest. Two strikes.
Dark.
Fifteen seconds. Shin retrieved his chisel and moved on. The efficiency was almost clinical. No wasted movement. No extended contact. The dead-spot kill was the product of everything he'd learned — the construct anatomy from the disc's wireframe, the seam-targeting from his own experimentation, the mana-flow analysis from the one-second overlay. All compressed into a fifteen-second sequence that turned C+-rank crystal constructs into experience points with the mechanical reliability of a factory process.
Eighteen experience. 910.3.
Kill two. Corridor five. Another standard. Same technique. Fifteen seconds. The shoulder dead spot was consistent — same location, same depth, same vulnerability. The dungeon core hadn't reinforced this one yet.
Eighteen experience. 928.3.
Kill three. Corridor nine. Shin set up behind the construct, positioned the chisel at the right shoulder, and struck.
The chisel bounced.
The dead spot was gone. The crystal at the right shoulder — the specific intersection where two mana channels crossed and created a flow-thin zone — was reinforced. The thinness had been filled in. The channels had been rerouted, their intersection smoothed, the vulnerability eliminated as cleanly as a patch applied to a software bug.
The dungeon core had learned. Not just the seam reinforcement it had been doing — this was targeted. Specific to the dead spot. Specific to the technique Shin had used for exactly two kills, which meant the core had analyzed the damage pattern from those kills and deployed a counter in the span of minutes.
The construct turned. Shin backed off. Reset.
The shoulder was closed. But the dead spot wasn't the only vulnerability he'd seen during the disc's one-second overlay. The mana channels crossed at other points too — the left hip, where channels from the legs met channels from the torso. The back of the neck, where head channels joined the spine-equivalent. Each intersection was a potential dead spot, a place where flow thinning created structural weakness.
If the dungeon core had reinforced the shoulder, had it reinforced the others?
Shin circled the construct. Found its left hip. Placed the chisel.
Struck.
The chisel sank. Not as cleanly as the shoulder dead spot — this intersection was smaller, the thinning less pronounced — but the crystal gave way. Two extra strikes to penetrate, but penetration happened. The construct's left leg collapsed. It crashed to the floor, one-legged, arms swinging.
Chest. Three strikes. Dark.
Twenty-two seconds. Slower than the shoulder kills, but functional. The dungeon core had patched the most obvious vulnerability and missed — or hadn't yet reached — the secondary ones. Shin had maybe three or four kills before the hip dead spot was reinforced too.
Eighteen experience. 946.3.
Kill four. Corridor thirteen. The construct here was one of the rose-crystal variants — the steady-core model he'd first encountered during the disc activation. Shin used the hip dead spot. It held. The kill took twenty seconds.
Eighteen experience. 964.3.
Four kills. Seventy-two experience. Thirty-six to go. Two more constructs.
Shin moved through the upper grid, checking corridors. Empty. Empty. Empty. He'd killed four in quick succession, and the respawn cycle for the upper level was measured in hours, not minutes. The constructs he'd destroyed wouldn't be replaced until well after he needed to leave.
Two more kills, and the upper grid was depopulated.
He went deeper. Into the transitional zone. Past the tool-marked corridors, past the rest alcoves, toward the areas where he'd found constructs on previous sessions. Corridors fourteen through twenty, where the crystal darkened incrementally and the mana concentration climbed.
Corridor fourteen. Empty.
Corridor sixteen. Empty.
Corridor eighteen. Empty. The constructs that had patrolled the transitional zone were gone — killed on previous sessions and not yet respawned. The dungeon core was allocating its respawn resources to the upper grid, where the primary threat had been, and the transitional zone was drained.
One construct. He needed one more kill. Eighteen experience. Thirty-six points between him and Level 1.
Corridor twenty. The boundary. Where the amber crystal shifted to brown, where the tool marks had stopped mid-wall, where the lower dungeon began.
A construct stood at the boundary line.
Not in the amber section. Not in the brown section. On the line itself, positioned with mechanical precision at the exact point where the crystal changed color, as if placed there by a hand that understood the significance of the threshold.
It was wrong.
Wrong height — six feet instead of five, a full foot taller than any construct Shin had fought. Wrong build — broader at the shoulders, thicker at the chest, with arms that were proportioned for power rather than patrol. Wrong crystal — not the warm amber of the upper grid or the rose-tint of the variants, but a deep ochre, the color of old amber buried in earth, dense and light-absorbing in a way that made the construct look like a shadow given form.
And the mana core was wrong. Larger than the standard cores, visible through the ochre crystal as a sphere of concentrated light that pulsed at a rate Shin could count — three pulses per second, nearly vibrating, far faster than the one-per-second rhythm of the C+-rank constructs. The energy output was visibly greater. The light was brighter. The ambient mana around the construct shimmered with excess bleed, creating a halo effect that made the air waver.
A guardian. Not a patrol unit — a fixed sentry, posted at the entrance to the deep level, built from harder material and powered by a stronger core. This was the dungeon's answer to intrusion: not more standard constructs, but a qualitatively different defender at the threshold that mattered most.
B-rank. Maybe B+. Shin had no way to verify, but the gap between this construct and the C+-rank units he'd been killing was visible in every dimension — height, mass, crystal density, core intensity. This was the kind of enemy that required a party of awakened hunters with proper weapons and level-appropriate stats. The kind of enemy that a Level 0 with two construct cores and zero medical tape should walk away from.
Eighteen experience. One kill. The only construct left in a depopulated dungeon, standing at the gate of the deep level like a toll collector for the road to Level 1.
Shin assessed. The dead-spot technique might not work — the ochre crystal was denser, the mana channels presumably reinforced by a core that produced three times the standard energy output. But the construct was humanoid. Same basic anatomy. The same design philosophy that gave the C+-rank units their vulnerabilities should apply to the B-rank guardian, even if those vulnerabilities were smaller and harder to exploit.
Null Presence held. The guardian's featureless head was oriented toward the deep level, watching the brown crystal corridors beyond the boundary. It wasn't tracking Shin. It didn't know he was there.
He circled to its left flank. The hip dead spot — the secondary vulnerability. If the dungeon core had reinforced the guardian's shoulders (likely, given it was a premium defender), the hip might still be thin.
Shin positioned the chisel against the guardian's left hip joint. The ochre crystal was warm under the chisel's point — warmer than the standard constructs, radiating the excess energy of its oversized core.
He struck.
The hammer-core hit the chisel. The impact transmitted through the point and into the crystal. And stopped. The ochre crystal didn't crack. Didn't fracture. Didn't give at all. The chisel's pointed tip had left a white scuff mark on the surface and nothing more.
Shin struck again. Harder. Full shoulder rotation, every ounce of force his battered body could generate behind the hammer-core.
The chisel bit a quarter-millimeter. A chip. A flake of ochre dust that fell to the floor like a discarded eyelash.
The guardian turned.
Its head rotated toward the sound — not the full-body spin of the standard constructs, but a smooth, articulated head turn that was faster and more precise. The featureless ovoid faced Shin. The mana core flared.
And then it moved.
The guardian's fist came around in a hook that was nothing like the standard constructs' swings. This was coordinated. Shoulder rotation driving elbow extension driving fist acceleration, a kinetic chain that produced more force than anything Shin had faced in the Foundry. He saw it coming — years of dodging punches in Tier 5 alleys and weeks of fighting crystal humanoids had given him the ability to read a hook — but his body's response was a fraction too slow, the damaged knee and bruised hips stealing the milliseconds that would have made the difference between dodge and contact.
The fist caught his jaw.
Not a glancing blow. Not an incidental contact during a grappling sequence. A clean, targeted hit to the mandible that snapped his head sideways and sent the world into a white-noise spin of disoriented pain. His teeth clacked together — the lower jaw slamming into the upper with force that the bones weren't designed for — and something in his mouth moved. A tooth. Upper left premolar. The root had loosened in the socket, the impact transmitting through bone to the dental root, and the tooth shifted a millimeter in a direction that teeth should not shift.
His lip split. The inside of his mouth filled with the salt-copper taste of blood pooling between his cheek and gum. He hit the corridor wall shoulder-first and bounced off it, legs operating on reflex, keeping him upright when the rational response was to crumble.
The guardian advanced. Its second punch came faster — a straight jab, not a hook, aimed at center mass. Shin dropped to a crouch and the fist went over his head, cratering the wall behind him. Crystal shrapnel sprayed. A chip caught his ear, opening a cut that bled immediately in the thin-skinned way that ear wounds bleed.
He had to move. The guardian was between him and the corridor behind — retreat meant going past it, which meant going through its striking range. Advance meant going deeper into the transitional zone, toward the deep level boundary, where the brown crystal offered no familiarity.
He went forward. Under the guardian's arm, past its legs, scrambling on all fours because his balance was gone and his jaw was screaming and the loose tooth was sending signals that his brain was classifying as urgent. The guardian pivoted — smooth, coordinated, fast — and its foot came down where Shin's hand had been a half-second before.
On his feet. Behind the guardian now. Its back was to him, the broad ochre shoulders and thick midsection presenting a wall of crystal that his chisel had barely scratched.
The hip hadn't worked. The crystal was too dense, too reinforced by the high-output core. The standard dead spots weren't available. But the guardian was humanoid, and humanoid meant joints, and joints meant connective tissue, and connective tissue was organic.
The seams. Back to basics. Not dead spots — seams. The organic material between crystal segments that held the guardian's body together.
Shin found the left shoulder seam. Wider than the standard constructs' seams — the guardian's larger build meant larger joints, which meant more connective tissue. He set the chisel against it and hammered.
The organic material was tougher than the standards'. Denser. Reinforced. But it was still organic. Still softer than crystal. The chisel bit on the second strike, and by the fourth it was embedded an inch deep in the shoulder joint.
The guardian spun. Left arm — the arm connected to the compromised shoulder — coming around in a backhand. Shin ducked. The arm passed over him. But the chisel, embedded in the shoulder, came with the arm's rotation, and the handle wrenched from Shin's grip.
His chisel was stuck in the guardian's shoulder. His primary weapon, embedded in the joint, rotating away from him as the guardian completed its turn. He had the hammer-core in his right hand and nothing in his left.
The guardian faced him. Both fists raised. Mana core blazing. The chisel protruded from its left shoulder like a bone spur, embedded but not disabling — the joint was damaged but not severed, and the arm still moved, still punched, still functioned at maybe seventy percent.
It charged.
The corridor was nine feet wide. The guardian was three feet across at the shoulders. Shin had three feet of clearance on each side, and the guardian's reach covered four.
He went right. The guardian's fist tracked him — not the left, the right, the undamaged arm — and the punch connected with the corridor wall as Shin ducked under it. Crystal exploded. The wall cracked in a starburst pattern, and Shin felt the shockwave through the floor.
He grabbed the chisel. Both hands on the protruding handle, feet braced against the guardian's hip, pulling with everything his damaged body could produce. The chisel tore free, bringing a chunk of shoulder tissue with it, and the guardian's left arm dropped to half-functionality.
The guardian's right fist caught him in the ribs. Left side. The side that had been damaged since Hollowfield, that had been cracked and taped and retaped and ignored for weeks, that had accepted its role as the body's designated shock absorber with the resignation of a structure that knew it would be rebuilt anyway.
The rib broke.
Not cracked. Not bruised. Broke. A clean fracture — he felt it go, the specific tactile sensation of bone separating that was distinct from all other types of damage, a pop followed by a grinding that was both felt and heard, internal and external simultaneously.
Shin hit the wall. The broken rib rearranged his breathing from voluntary to conditional — inhale was possible if shallow, exhale was possible if controlled, anything deeper was vetoed by a pain response that went beyond negotiation into absolute prohibition.
The guardian stood over him. Six feet of ochre crystal, core blazing, both fists raised. The left arm moved stiffly — the chisel had damaged the shoulder joint — but the right arm was fully functional, cocked back for a strike that would drive Shin through the wall behind him.
He looked up at the featureless head. The blazing core. The ochre crystal that his tools couldn't penetrate and his body couldn't survive.
Eighteen experience. That was all.
The guardian's fist began its descent.
Shin drove the chisel upward, into the space beneath the guardian's chin — the neck joint, the smallest seam, the one place where the head met the torso and the connective tissue was exposed because no amount of crystal reinforcement could eliminate the gap that allowed the head to turn.
The chisel entered the seam. The guardian's fist was still coming. Shin's other hand — the hammer-core, slick with blood from his split knuckles — rose to meet the chisel's butt.
The fist and the hammer fell at the same time.
