Deshi was talking to someone who didn't belong.
Shin saw it from thirty meters out — the distance between the bus stop and the barracks entrance, a stretch of packed dirt that he'd walked a thousand times without noticing anything worth noticing. But Deshi was standing outside the supply container, the one he'd converted from porter storage into his little markup empire, and next to him stood a woman whose posture told a story that her clothes were trying to deny.
The clothes said civilian. Dark jacket, gray slacks, nothing branded or distinctive. But the boots were wrong. Clean leather, recent sole, the kind of footwear that cost more than Deshi's monthly take. And her posture — spine straight, weight centered, shoulders back in a way that wasn't casual. That was trained. Military, security, or awakened service. Nobody in Tier 5 stood like that unless they'd been taught to stand like that somewhere else.
The woman saw Shin coming. Or rather, she registered movement on the approach road and made a decision — the kind of quick, calibrated decision that involved assessing a threat level and choosing a response. She turned to Deshi, said something short, and walked away. Not hurried. Controlled. She crossed the scrap yard lot and turned the corner toward the main road before Shin reached the barracks.
Deshi watched her go. His hands were doing things — adjusting the collar of his jacket, touching the back of his neck, picking at the cuff of his sleeve. The inventory of fidgets that people who aren't good liars run through when the lie is fresh.
"Hey, man." Deshi's voice was a half-step higher than its resting pitch. He smiled. The smile had too many teeth in it. "Good shift?"
Shin stopped in front of the supply container. He didn't look in the direction the woman had gone. Looking would signal that he'd noticed, and signaling was a currency he couldn't afford to spend.
"Who was that?"
"Who? Oh — supplier. New tape source, actually. She's got medical-grade stuff coming in from a Tier 3 factory outlet. Better adhesive, waterproof backing. Thought I'd see if the price worked."
A supplier. Who wore hundred-credit boots and stood like she'd been through combat posture training.
"Good price?"
"Still negotiating, you know how it is." Deshi laughed. The laugh was a beat too late and a note too loud, the kind of laugh that existed to fill space where confidence should have been. "Might have some in stock by next week. You want me to save you a roll?"
"Sure."
Shin walked inside. Changed his shirt. Unwrapped the cloth from his hands, washed them in the shared bathroom — cold water turning pink as it ran over split knuckles and the palm wound that had become a permanent feature of his left hand's geography — and re-wrapped with the last of his current tape. He had one roll left. He'd bought three rolls from Deshi four days ago.
Three rolls of medical tape. Two packs of ration bars. A box of heavy-gauge rubber bands that Shin used to strap the construct cores to his palms during kills. And a question, asked casually between purchases, about where a person might find a hand chisel in Tier 5.
He'd asked that question six days ago. Deshi had said he'd look into it, asked what kind of work needed a chisel, and Shin had said "night work" and left it at that. Night work. In Tier 5, "night work" covered everything from warehouse security to illegal salvage to things that nobody discussed in daylight. It was supposed to be a non-answer. A conversational dead end.
Except Deshi was the kind of person who noticed patterns, because noticing patterns was how you ran a supply business in the margins. You watched what people bought, how often, in what quantities, and you built a picture of their needs that let you stock the right inventory. Deshi knew that Shin bought medical tape in bulk — more than a dock worker should need. He knew Shin bought ration bars — portable food, the kind you eat when you're away from the barracks and can't cook. He knew Shin had asked about chisels and specified heavy-gauge, the kind rated for stone or hard material.
Medical tape. Portable food. A stone chisel. Night work.
Deshi wasn't smart enough to know what the picture meant. But he was smart enough to know that the picture was worth something to someone, and two hundred credits — if that was the number — was more than Deshi made in two weeks of supply-container markup.
Shin lay on the cot. Stared at the ceiling. Counted.
Not rust spots. Variables.
---
He waited until Deshi left for his evening shift — dock work, the late rotation that Cho ran for porters who preferred the smaller crowds and the quieter supervisors. Deshi walked out at 6 PM, duffel bag over his shoulder, heading toward the Block 4 bus stop with the easy stride of a man whose conscience was padded with two hundred credits of someone else's money.
The supply container was locked. Deshi's lock — a combination padlock, mid-grade, the kind sold at any Tier 5 hardware stall. Shin knew the combination because he'd watched Deshi open it twice, standing at the angle where the dial's numbers were visible, storing the sequence in the same part of his brain that stored dungeon layouts and construct patrol patterns.
He wasn't proud of this. But pride was a luxury. Shin hadn't had it since the night the System assigned him zero stats.
The lock opened. The supply container was small — six feet by eight, shelves along three walls, stacked with the inventory of a man who'd figured out that Tier 5's misery was a reliable market. Medical supplies on the left: tape, gauze, antiseptic wipes, cheap painkillers in blister packs. Food in the center: ration bars, canned goods, instant noodle packets. Tools and miscellaneous on the right: work gloves, boot laces, flashlight batteries, a rack of utility knives.
Shin didn't touch the inventory. He was looking for paperwork. Deshi was old-fashioned — he kept handwritten records because he didn't trust phones and didn't own a computer. The records lived in a metal box under the bottom shelf, the kind of lockbox you'd keep cash in, except Deshi kept it unlocked because nobody in the barracks robbed the supply guy. The supply guy was infrastructure. You didn't steal from infrastructure.
The box contained a ledger. Spiral-bound, cheap, with Deshi's cramped handwriting filling pages of columns: item, quantity, buyer, date, price. A business record of every transaction conducted through the supply container for the past three months.
Shin flipped to the recent entries. Found his name. The entries were clinical — Deshi's handwriting was accountant-neat despite the cramped size.
*Shin K. — 3x med tape (heavy) — 12 cr — Feb 8*
*Shin K. — 2x ration bar (10pk) — 8 cr — Feb 8*
*Shin K. — 1x rubber band (hvy gauge, box) — 3 cr — Feb 9*
*Shin K. — inquiry: hand chisel (stone grade) — no stock — Feb 9*
*Shin K. — 2x med tape — 8 cr — Feb 11*
*Shin K. — 1x ration bar (10pk) — 4 cr — Feb 12*
Six entries. A purchase history that, to anyone who understood the language of survival logistics, told a specific story. Someone who was getting hurt regularly. Someone who ate away from home. Someone who worked with stone and needed tools designed for hard material.
Below the last entry, in different ink — blue, where the ledger entries were black — a note. Not in Deshi's handwriting. Smaller, more precise, with the particular uniformity of someone who'd been trained to write clearly.
*Subject: Shin Kaida, porter, Barracks 7-C*
*Purchase pattern: medical supplies (heavy-grade, bulk), portable rations, tool inquiry (chisel, stone-grade)*
*Activity window: nighttime (confirmed via barracks exit logs — exits 10-11 PM, returns 4-6 AM)*
*Probable trajectory: northwest, waste zone sector (per directional analysis of transit card usage)*
*Active night access confirmed. Waste zone trajectory probable.*
*Payment: 200 credits. Follow-up contingent on location confirmation.*
The note was on a separate piece of paper, folded and tucked into the ledger at the page where Shin's entries appeared. The paper was good stock — heavier than what you'd find in Tier 5, with a slight texture that suggested stationery from Tier 3 or above.
Shin read it twice. Folded it back into place. Closed the ledger. Replaced the box. Locked the container.
He stood in the yard between the barracks and the supply container, in the evening light that turned Tier 5's concrete and scrap metal into something that looked almost warm, and processed the information.
Deshi had sold him out. Not maliciously — Deshi wasn't the kind. Deshi was the kind who saw two hundred credits and made the calculation that every Tier 5 resident made when survival math overrode loyalty math. The woman had come asking about unusual purchase patterns from the porter barracks. Deshi had checked his ledger, found the pattern, and named a price. Business.
Two hundred credits to confirm that a porter named Shin Kaida was buying medical supplies and stone tools and leaving the barracks at night. Two hundred credits and a follow-up payment contingent on "location confirmation."
They didn't know where he went yet. The transit card analysis — his bus card, the cheap rechargeable that logged pickup and drop-off points — showed him heading northwest toward the waste zone, but the card stopped logging when he left the bus network. They had trajectory, not destination. Direction, not coordinates.
The woman wasn't Bureau. The Bureau had access to transit records directly — they wouldn't need to buy them from a porter's supply hustle. And Bureau operatives wore Bureau-adjacent clothing: dark gray, functional, standardized. The woman's clothes had been deliberately non-institutional. Blending in. Trying to look like a Tier 5 civilian and almost succeeding, except for the boots and the posture and the handwriting that was too precise.
Not a guild. Guild scouts wore insignia — required by law, the Hunter Registration Act mandating visible guild affiliation for any operative conducting field intelligence. No insignia meant either illegal operation or non-guild.
Something else. A third category that Shin didn't have a name for.
Sato's words: *The ones I'm talking about don't carry notebooks.*
The mystery researcher in Ashburn had carried a notebook. The woman outside the barracks hadn't. Different people. Different organizations. Converging on the same target from different directions.
Shin went inside. Ate cold rice. Taped his hands. Waited for 10 PM.

Night six. The Foundry. The grind didn't stop because the world was closing in. The grind was what made the world's closing-in survivable, because the grind had a number attached to it, and numbers were the only honest thing Shin had left.
766 going in. Three kills tonight. Fifty-four experience. That would put him at 820. Twenty-seven from his mother's line.
The first construct was in corridor three, a standard model, and Shin took it down with the chisel-and-hammer technique in forty seconds. Approach from behind. Set the chisel-core against the lower back. Three hammer strikes to drive it through — he was stronger now, not in stats but in technique, the economy of motion that turns a six-hit sequence into a three-hit sequence through better angle selection and more committed force transfer. The lumbar crystal cracked. Circle front. Chest. Four strikes. Core dark.
His right hand was learning. The knuckles had scabbed over the scabs, building a crust of damaged skin that served as crude armor. The split fourth knuckle had closed under fresh scab tissue that was thicker than the original skin, a callus-in-progress that turned what had been an open wound into a functional striking surface. The body adapting. Not well. Not cleanly. But adapting, the way Tier 5 bodies adapted to everything — through scar tissue and repeated abuse until the damaged part was tougher than the original.
Eighteen experience. 784.
The second construct was in corridor eleven, a variant with slightly longer legs that gave it a faster patrol speed. Shin matched it, set up behind it, and began the sequence. The chisel slipped on the first strike — the construct's crystal surface was smoother than average, and the chisel-core's pointed end skated across it rather than biting. He adjusted. Found a seam between crystal segments where the organic connective tissue created a slight depression. Placed the chisel there. Hammered.
The chisel drove through the seam rather than the crystal — punching through organic material into the construct's interior, bypassing the amber shell entirely. The damage was different: instead of fracturing the lumbar crystal, the chisel had penetrated the connective tissue and disrupted the joint's internal structure. The construct's hip separated. Its legs went in different directions. It crashed to the floor, upper body still functional, arms swinging, head scanning.
A downed construct was still dangerous — the arms could sweep the floor in arcs that covered four feet in each direction. But it was immobile. Shin circled to the front, staying outside arm range, and when the arms committed to a left sweep, he stepped inside on the right and drove the chisel into the chest.
Three strikes. Mana core. Dark.
That kill was cleaner than any he'd managed. The seam-targeting — going through organic tissue instead of crystal — was faster, quieter, and required less force. The constructs' crystal armor was their defense, but the joints between segments were organic, and organic material yielded to the chisel-core without the need for hammering through amber.
New technique. Better than lumbar fracturing. Joint disruption — targeting the connective tissue between segments, collapsing the construct's mobility before going for the core. It required finding the seams, which were visible on the standard models as thin dark lines between crystal segments, but on the thicker variants the seams were harder to locate.
Eighteen experience. 802.
Shin sat in his rest alcove in corridor fourteen and ate a ration bar. The number sat in his vision like a road marker. 802. Forty-five to 847. Two and a half kills.
His mother's number was coming. Not in days — in kills. Two more constructs and he'd be standing at 838, and the third would push him past 847 into territory she'd never mapped. Into the unknown beyond the line where a Level 0 had been found and stopped and—
He didn't know. That was the core of it. He didn't know what had happened to her at 847. Killed? Captured? Contained? The word "found" could mean any of those, and Sato's silence on the specifics was either mercy or strategy and Shin couldn't afford to mistake one for the other.
What he could calculate was this: if 847 was an alarm line — a System-monitored threshold that triggered when a Level 0's shadow experience reached a certain percentage — then he was two kills from tripping it. And if the alarm was still active, still monitored by the same mechanism that had detected his mother three decades ago, then two kills from now, something would change.
Maybe nothing would happen. Maybe the alarm had been decommissioned. Maybe his mother's detection had been human, not systemic — a person watching, not a machine monitoring — and the 847 was just the number where her luck ran out.
Or maybe two kills from now, the System would register a shadow experience accumulation in an entity classified as Level 0, and a notification would appear in some database that Shin couldn't see, and someone — or something — would start looking for the source.
The third construct was in corridor eighteen. A standard model. Shin took it down with the seam-targeting technique — hip joint, three strikes, collapse, chest, four strikes, dark. Clean. Forty seconds.
**[Shadow Experience: 820.3/1,000]**
Twenty-seven to 847.
Shin climbed out. Waste zone. Wall. Bus.
---
The barracks at 5 AM. Deshi's supply container was closed, locked, the same as when Shin had left it. Deshi's cot was empty — still on his dock shift, or staying somewhere else. Maybe spending the two hundred credits. Maybe meeting the woman with the clean boots. Maybe doing whatever Tier 5 entrepreneurs did when the profit margin on betrayal exceeded the profit margin on medical tape.
Shin sat on his cot and laid out the variables.
Deshi knew his purchase pattern. The woman knew his schedule and his general direction of travel. The transit card data said northwest, waste zone. The follow-up payment was contingent on location confirmation — meaning they didn't have the Foundry yet, but they were looking.
Timeline. The woman had visited Deshi recently — today or yesterday, based on the fresh ink of the note. The follow-up would require surveillance: someone watching Shin leave the barracks, tracking his route over the wall, following him through the waste zone to the Foundry. That took resources. People. Equipment. Time to set up.
If they started surveillance tonight, they'd need at least one night of tracking to confirm the destination. That gave Shin tomorrow night — maybe — before the location was compromised.
Two nights. He needed ten more kills to reach 1,000. At three per night, that was three more sessions. But if the Foundry was compromised in two—
He'd need to accelerate. Four kills per night instead of three. Maybe five, if the seam-targeting technique held up and the constructs didn't upgrade faster than he could adapt. Five kills in one session would bring him to 910 tomorrow and 1,000 the night after.
Two nights. Ten kills. A body that was reporting damage at every joint and a clock that had just started ticking because a man named Deshi had looked at two hundred credits and decided that Shin's secrets were worth less than six weeks of dock wages.
Shin didn't blame him. Blaming Deshi would require investing emotional energy in a transaction that was, from Deshi's perspective, perfectly rational. Two hundred credits was real money. Shin's privacy was an abstraction. In Tier 5, real money beat abstraction every time, and Shin would have calculated the same odds if the positions were reversed.
What he calculated now was different. Not anger. Logistics.
He needed to change his route. Not tonight — tonight was done. Tomorrow. Different bus. Different time. Leave from a different section of the wall, approach the Foundry from the east instead of the northwest. Confuse the trajectory data. Make the surveillance harder.
He needed to strip his purchases from Deshi's records. Not possible — the ledger was Deshi's, and stealing it would alert Deshi that Shin knew. Better to leave it. Let the woman think her intelligence was intact while Shin changed the variables underneath it.
He needed to move faster. The Foundry was a finite resource — not because the constructs would run out, but because the window of secrecy was closing. Every hour spent not grinding was an hour the woman's people spent setting up their watch.
Shin rewrapped his hands. The tape was almost gone. He'd need more, and he couldn't buy from Deshi anymore, which meant finding another source, which meant spending time on logistics instead of grinding, which meant—
The disc was warm.
He stopped. His hand was on the calibration disc in his pocket, reaching past it for the construct cores, and the disc — dead for days, dark and inert since it had shown him the mana-pathway image — was warm.
Not hot. Not blazing. Just warm. Body temperature, the way it had been when Sato first handed it to him. The amber zero on its surface was dark, but the metal itself had a faint sheen — not glowing, not active, but not dead either. A pilot light. Something in standby.
He held it in his palm. The warmth didn't change. Didn't pulse. Just sat there, steady, like a hand pressed against his through a wall.
The disc had activated near dungeons before — warming as he approached mana sources, cooling as he moved away. But the barracks was nowhere near a dungeon. The nearest mana source was the Foundry, miles away across the waste zone.
Unless the disc wasn't responding to external mana. Unless it was responding to internal mana — to Shin's own accumulation, 820 shadow experience worth of kill-energy stored in a body that the System called zero but that the disc, apparently, measured differently.
Or unless the disc was responding to something else entirely. Something that the word "calibration" implied: an alignment process, a tuning, a synchronization that happened not when the disc was near mana but when the disc's owner reached a specific state.
820 out of 1,000. Eighty-two percent. Approaching the threshold. Approaching 847.
The disc sat in his palm, warm and patient, measuring something he couldn't see.
