He rented the unit on a Tuesday, which felt, by that point, like the only day of the week the important things in his life had any interest in happening on.
Day 15. A hundred and fifty Tech Points, climbing the same ten a day it had climbed every day since the number first appeared, and Mohamed had spent the intervening week doing the one part of the project that didn't require the System's permission at all: figuring out where, physically, in the city of Louisville, Kentucky, a man was supposed to put a chemical vapor deposition chamber he didn't own yet.
The apartment was out. He'd known that within an hour of reading the CVD chamber's description a second time — *quartz reaction chamber, gas flow assembly, thermal control schematic* — and had spent one uncomfortable evening running the numbers on what an argon leak, or a furnace fire, or simply the noise of a vacuum pump at eleven at night would do to his lease, his neighbors, and his own continued ability to sleep in the same room as the thing he was building. A one-bedroom off Bardstown Road with vinyl plank flooring and a downstairs neighbor who complained about footsteps was not a laboratory. It was not going to become one no matter how badly he wanted a shortcut.
He looked at three places before he chose one.
A shared makerspace off Frankfort Avenue came first — sixty dollars a month, communal tools, a waiting list for the 3D printers, and, critically, seven other members with keys to the same building. An open floor plan offered no version of privacy for a man who had decided, without quite articulating the decision to himself yet, that nobody could know what he was actually building or why. He left after twenty minutes of the tour, polite, noncommittal, already crossing it off the list before the woman showing him around had finished her sentence about the community potluck.
Then a warehouse subdivision in Portland — industrial, cheap, twenty-two hundred square feet going for four hundred a month, absurdly large for what he currently needed and absurdly inexpensive for what it actually was. Entirely wrong anyway, for a man with a hundred and fifty Tech Points and no real idea yet whether any of this would amount to more than a hobby that quietly emptied his savings account. He didn't need a warehouse. He needed a room with a door that locked.
Poplar Level Road settled it. A Public Storage facility, a row of orange roll-up doors behind a chain-link fence, keypad access, twenty-four hours, no other tenants likely to wander past his door out of curiosity because nobody wandered anywhere in a storage facility — you came, you did your business with your own boxes, you left.
Unit 114 was ten feet by ten feet, climate-controlled in the loose sense that the whole building shared one HVAC system that kept things above freezing and below unbearable, with a single fluorescent tube overhead and a louvered vent near the ceiling that he stood under for a long moment, doing the math on airflow the way he'd once done it for a lab class nine years ago that he'd never expected to need again.
Eighty-nine dollars a month.
He signed the agreement in the front office, a small room with a space heater and a rack of half-empty moving-box supplies, across a counter from a man named Gary who did not ask what he intended to store and would not, Mohamed suspected, have cared much either way.
"Climate control's not exact," Gary said, sliding the paperwork across. "It's not gonna freeze your stuff in January, but don't go storing wine down there thinking it's a cellar."
"I'm not storing wine."
"Most people say that and it's exactly wine." Gary shrugged, entirely uninvested in the outcome either way. "Code's on the sheet. Gate closes at midnight, opens at six. You're not gonna set anything on fire down there, are you?"
"No," Mohamed said, with the specific flat honesty of a man who genuinely believed it and also understood, distantly, that it was the kind of answer every person who eventually did set something on fire had also given.
"Great. Sign here."
He signed. Eighty-nine dollars a month, first and last up front, out of four thousand two hundred dollars that had, until three weeks ago, existed for no purpose he could have named.

He drove to the Home Depot on Bardstown Road that same evening with a list he'd written on the legal pad the night before, standing in the aisle doing arithmetic that had nothing to do with Tech Points at all.
A hollow-core door slab, the cheapest one in the millwork aisle, thirty-one dollars. Two sawhorses, twenty-two dollars each. A roll of outlet-grade extension cord, a work light, a box of basic hand tools he mostly already owned but was missing three specific sizes of, a folding chair.
He stood in front of the door slabs longer than the purchase warranted, running his hand along the hollow edge of one, feeling the lightness of it, and thought — unbidden, the way thoughts arrived at odd moments lately — about his father's workbench, still sitting disassembled in his mother's garage in Shively, four two-by-fours and a laminated top his father had built the summer Mohamed was four years old and left behind, along with most things, when he went to Texas in 2007.
He could have driven to Shively and gotten it. Twenty minutes, a favor from a neighbor with a truck, free.
He didn't.
He wasn't ready yet to explain to his mother why he suddenly needed a workbench, and a hollow-core door on two sawhorses cost fifty-three dollars and required no explanation to anyone, and some part of him — the same part that had learned, at twenty-two, to solve a coffee machine's leak with a dish towel instead of a new seal — had already decided that the cheapest solution that worked was the correct one, at least until he understood what, exactly, he was building toward.
He assembled it in the storage unit that night under the single fluorescent tube, the door slab laid flat across the sawhorses, level enough, sturdy enough, ugly in the specific way that only a piece of furniture built from the wrong materials for its purpose can be ugly.
It was not a lab. He stood back and looked at it — a workbench that used to be a door, in a room that used to hold somebody's Christmas decorations, under a landlord's fluorescent tube, behind a keypad gate that closed at midnight — and understood, with total clarity, that it was not a lab and was never going to look like one no matter what eventually got built on top of it.
But it was his. Eighty-nine dollars a month bought him a door that locked and nobody who cared what was behind it, and having a space — the sheer fact of a space, however unglamorous — felt, standing there at nine o'clock on a Tuesday night with sawdust on his hands, like the actual first rung of the ladder, more than the number in the corner of his vision had ever quite managed to feel.
---
The days after that had a shape to them that he was starting to trust the way you trust a commute you've driven often enough to stop consciously steering through.
Wake. Check the number. Coffee, dish towel, drive, desk, the Ohio Valley numbers that Cincinnati kept getting wrong in the exact same way every quarter, a sandwich, drive home — sometimes straight to the apartment, three or four evenings a week now straight to Poplar Level Road instead, where he'd sit on the folding chair under the fluorescent tube and read whatever he could find about vapor deposition on his phone, since he didn't yet own the blueprint and wasn't going to waste the wait doing nothing.
He learned, in those evenings, that the CVD chamber's basic principle wasn't exotic at all — heat a substrate, introduce a gas, let a reaction deposit a thin film where you wanted one — and that the difficulty had never been the concept. It had always been the precision. Temperature control within a few degrees. Gas flow rates measured in standard cubic centimeters per minute. Tolerances that a university lab achieved with equipment costing more than his entire savings account, and that he was apparently expected to achieve with whatever a blueprint from an impossible System and a Home Depot receipt could produce between them.
He didn't know yet if that was going to work. Nobody did. That was, he understood by day sixteen or so, sitting alone in a storage unit with a laptop balanced on a door-slab workbench, more or less the entire premise of everything that had happened to him since a Tuesday three weeks back — that a great deal of it was going to have to be found out by doing it, and no amount of research on his phone in a folding chair was going to substitute for the moment the blueprint actually arrived and told him what he was really working with.

The gas distributor's office in Jeffersontown was a low brick building behind a chain-link lot full of cylinder racks, and the woman at the counter — a laminated name tag that said DONNA, the same bored competence he remembered from the phone — looked up when the bell over the door rang and did a small double-take that told him she remembered the call.
"Research use," she said, before he'd gotten two steps in. "Argon."
"That's me."
"You get the license?"
He set the printout on the counter — Vance Research, sole proprietorship, forty-one dollars and ten minutes online, the most consequential piece of paper he'd ever produced with that little effort. Donna looked it over with the specific efficiency of someone who had processed a thousand of these and had stopped being impressed by any of them, business or hobby, decades ago.
"All right." She pulled a form from under the counter. "Smallest cylinder we carry is a size 80 — that's about two hundred and fifty cubic feet, should last you a good while if you're not running anything continuous. Rental's twelve dollars a month on the tank, gas itself is around forty. You want a regulator too, or you got one?"
"I need one."
"Everybody needs one the first time." She said it without unkindness, the specific patience of a woman who had watched a great many first-timers walk in not knowing what they didn't know. "Two-stage, get the two-stage, the single-stage ones drift on you as the tank empties and you'll chase your setpoint all day. I'll throw one in for ninety, it's not marked up much past what we pay."
"Two-stage. Yes."
"Delivery or pickup?"
"Pickup. I've got a hatchback, but I can make it work."
Donna looked at him for a moment — not unkindly, just the specific, assessing look of someone deciding how much unsolicited help a stranger deserved — and said, "Bungee cord in the trunk, cylinder valve facing up, don't let it roll. You'd be amazed how many people try to lay these things on their side like a duffel bag."
"I wouldn't have known that."
"Most people don't, till they do it wrong once." She rang him up. A hundred and fifty-one dollars, tank rental and gas and the regulator together, out of savings that were shrinking in a way he'd started tracking on the legal pad with the same discipline he used to track Cincinnati's freight variances. "You said research use. What's the research?"
Mohamed had the answer ready, the same answer he'd given Ray, worn smooth from use. "Materials project. Still figuring out if it goes anywhere."
"That's what they all say." Donna slid the receipt across. "Half my small accounts are exactly that — some guy in a garage or a storage unit with a project he's not ready to explain yet. Come back when the tank's low. We'll swap it."
He drove the eleven miles back to Poplar Level Road with a compressed gas cylinder bungeed upright in the trunk of a Corolla that had never, in eight years of ownership, been asked to carry anything more hazardous than a Christmas tree, and set it in the corner of unit 114 next to the door-slab workbench, and stood there for a moment looking at the two objects side by side — the cheapest furniture in the building supply aisle, and a tank of compressed argon rated for research use — and felt, for the first time since Tuesday three weeks ago, like the storage unit had actually started to look like something instead of nothing.

At work the following Monday, Ray rolled his chair the customary six inches and said, without preamble, "You get the tank?"
"What tank?"
"The gas tank. Argon. I looked it up after you sent me that link, you know. Argon's not the scary one — that's what the lady probably told you too, right? It's welding gas, mostly. Shielding gas. My brother-in-law's got a MIG welder in his garage, uses the same stuff." Ray looked entirely too pleased with his own research. "So what are you welding?"
"I'm not welding anything."
"Then what's the argon for?"
Mohamed considered, for the length of one breath, the actual answer — a nanostructure that didn't officially exist yet, grown under an inert atmosphere from a blueprint handed to him by something that had appeared in his kitchen on a Tuesday morning — and set it aside, the way he'd set aside every true answer for three weeks running.
"Keeping air away from something that reacts badly to air," he said, which was, strictly speaking, not a lie, and had the specific advantage of being boring enough that Ray's curiosity visibly deflated on contact with it.
"Huh. Sounds like chemistry."
"It's a materials thing. Chemistry-adjacent."
"You went to school for that, didn't you. Chemical engineering, or something." Ray said it slowly, like a man dusting off a fact he'd filed away years ago and forgotten he had. "You never use that degree here."
"No," Mohamed said. "I don't."
"Well." Ray rolled back to his own desk, apparently satisfied, or at least satisfied enough to let the subject rest for another few days. "Good you're using it for something. Even if it is just a hobby."
Mohamed didn't correct him. *Hobby* was doing a great deal of quiet work in that sentence, and he was, for now, content to let it.
---
He doubted it that night, alone, in a way he hadn't let himself doubt it yet.
Not the System's existence — that argument had settled itself in the first hour, the hand passing through the text, the internal consistency of a hallucination too disciplined to be one. What he doubted, sitting on the storage unit's folding chair at nine o'clock with the fluorescent tube humming overhead and the argon cylinder standing sentry in the corner, was simpler and older than that, and had nothing to do with anything supernatural at all.
*What if it doesn't work.*
Not the blueprint — he trusted the blueprint would arrive exactly as promised, precise and complete, the way the header text had been precise and complete from the first second he'd read it. What he doubted was himself: whether a data analyst with a chemical engineering degree he'd used exactly zero times in eight years could actually execute what the blueprint handed him, translate a schematic into a working chamber with his own two hands in a rented storage unit, with tools from a bait shop tackle box and a workbench that used to be a door.
He had built nothing with his hands since a senior design project in 2018 that had earned him a B-plus and a professor's mild, forgettable praise. Eight years was a long time to let a set of hands go soft.
He sat with the doubt instead of arguing with it, which was, he was starting to suspect, the only honest way to handle a fear that had a real chance of turning out to be correct. Tomorrow he'd have two hundred points. Tomorrow he'd know, at least, what he was actually being asked to build. Whether he could build it — that was a different question, and no amount of patient arithmetic in a storage unit was going to answer it in advance.
He turned off the work light and locked the roll-up door and stood for a second in the cold March dark outside unit 114, listening to the gate motor cycle somewhere down the row, and thought that this, more than the header text or the floating numbers or any of it, was the actual test the last three weeks had been quietly administering: not whether the world had gone strange, but whether he was still the kind of man who showed up the next morning anyway.
He was. He drove home to find out what tomorrow's two hundred points would actually buy him.
---
By day nineteen he had, arranged along one wall of unit 114: the workbench, the argon cylinder and its two-stage regulator, a folding chair, a work light clamped to a shelf bracket, a box of hand tools sorted into the tackle box, and a growing stack of printed spec sheets for a tube furnace he still hadn't bought.
He had not told Ray any more than the one text about the argon regulators. He had not told his mother anything beyond *a project, still figuring out if it goes anywhere,* the same sentence he'd given Donna, worn into a groove now from repetition, true in the narrowest possible sense and doing exactly the work he needed it to do — closing a conversation without lying outright, which mattered to him in a way he hadn't examined too closely yet but suspected he was going to need to, eventually, once the sentence stopped being sufficient.
He sat on the couch on a Sunday night with the apartment quiet and the water stain shaped like Ohio directly overhead, and did the math one more time, and found himself, for once, not dreading the answer.
**DAILY LOGIN — DAY 19**
**+10 Tech Points**
**Current Tech Points: 190**
Ten more tomorrow. Two hundred. The CVD chamber, the cheapest object in a catalog that had appeared inside his own skull nineteen days ago, finally, after three weeks of patient unglamorous arithmetic, within reach.
He looked at the number for a long time before he turned off the lamp.
"Tomorrow," he said, to the apartment, the way he'd said *okay* to it three weeks before, and went to bed early, and did not, for once, need to run the arithmetic a second time to fall asleep.
