The lamp on the desk burned low, its amber spirit-stone glow no larger than a coal, and the corners of the room belonged to the dark. Wind pressed at the east lattice, let go, and pressed again. Beneath the slate floor ran the faint hammer-vibration of the valley's forges, steady as a sleeping pulse. From across the inner courtyard came a thin blended murmur, a few footsteps and low voices carried thin by distance, none of it distinguishable, none of it meant for this room. The cold gathered the smells of the place: dry stone, old ink, mountain wool, and beneath those the bitter residue in the tea cup and the sour trace the poison left in his sweat.
Lu Feng stood near the southwestern corner, his shoulder a hand's width off the granite, and let his body make its nightly report. The cracked dantian kept its wrong warmth under his ribs. A thin high ache strung itself along his meridians. His right forearm trembled, and he closed the fingers into the palm and waited it out. His legs held, provided he asked nothing sudden of them. Upright, tonight, was enough.
The law would run. The last days settled that much: evidence that stood apart and agreed, testimony set down in writing, branches too wary of one another to allow a burial. What walked outside the walls now, flight and debt and patient leverage, no statute reached. Others would carry the reckoning. His own questions were asked, or waited on the forms, and the forms moved at the pace the forms moved. What remained for him stood in this room, in the dark, small enough to hold in two hands.
He could not fight. The practice jian along the south wall asked for a wrist that answered, and his wrist shook. What he owned was a trickle of qi drawn through ruined channels, and two lives of knowledge. Vance's world answered small strength with a tube, a charge, and burning powder, force thrown far and straight from any shoulder trained to hold level. This world offered no powder that Vance knew. It offered qi, and spirit iron that drank qi, and a young smith's hands that knew metal by touch. A rifle built on those terms existed nowhere that either life remembered. That meant only that no one drew it yet.
Vance's first rule of design was to decide the question and then ask the smallest honest version of it. Not a rifle tonight. Tonight, three questions. How much qi could he spend? What would carry it? What would hold it? Everything else waited on those answers, and answers began with measurement.
He walked north along the west wall, palm trailing the cool granite, and lowered himself onto the edge of the ironwood bed. The wool blanket gave off its faint lanolin smell. Door latched, window latched, lamp low: the room held its privacy around him. He set his feet flat on the slate, straightened his spine, and began.
The first measurement was himself. He drew breath low, found the thin current in the dantian, and eased it up through the right arm into the palm. The meridians burned at once, the old wrong heat. He held the trickle steady against it and counted his breaths. At eleven the current stuttered, thinned, and failed. He rested until the ache backed off, then did it again. Nine breaths. A third time, ten. After the third the ache sharpened into something with edges, cold sweat stood on his neck, and he stopped. The poison took its tithe for the work, same as always.
Eleven, nine, ten. That was the budget of him, written in breaths. Before the poison, the same exercise ran much longer and left him warm and hungry. Now it bought ten breaths and a cold sweat. He sat with the number a while and let it be only a number. Vance died at seventy-eight in a veterans' hospital, slowly, of many small failures added together, and spent his last years learning each morning what the day allowed and working inside the allowance. The memory came without bitterness. A body gave what it gave. Pretending otherwise wasted the little there was, and he refused to waste it.
When the sweat cooled he rose and crossed to the south wall, placing each step with the care the night's strength allowed. The jian lay along the wall where it always lay, well-used, its grip worn to the shape of his hand. He wrapped his fingers around the hilt and pushed the trickle in. The steel took it grudgingly. Most of the current slipped off and scattered; what little entered dragged like a man wading against a river. It held nothing at all. Ordinary steel was a road full of holes, and he set the thought aside in words so he would remember to write it down.
The tale has been illicitly lifted; should you spot it on Amazon, report the violation.
The spirit-iron dagger rested a short step east, plain and utilitarian, and he picked it up. The difference came at once. The spirit iron drank. The current left his palm and entered the metal more easily than it moved through his own channels, smooth as water finding its downward course. He fed it four breaths of trickle before the metal would take no more. Full, then. A dagger's worth of spirit iron swallowed four breaths of his best effort and asked for nothing after.
He carried it to the desk. The lamp's light lay low across the scarred ironwood, over the ink stone and the stacked scraps of paper. The glazed tea cup stood where it stood, cold and bitter at the bottom. He worked around its small circle and touched nothing. Testimony, of a kind. He kept it.
The hold came first. He charged the dagger and counted while the fullness in the metal faded: thirty breaths, give or take, before the feel of it went slack. He rested, charged it again, counted twenty-seven. A third charging gave thirty-one.
Then the release. He wet a fingertip, held it a finger-width off the blade's flat, and waited. When the metal finally let go, a thread of cool motion crossed the wet skin, there and gone, the ghost of a breeze. Twice more he charged and waited: once the same faint touch, once nothing he could swear to. He tore a narrow strip from a scrap of paper, held it dangling a finger-width from the blade, and charged the dagger yet again. When the release came, the strip stirred, a small shy shiver, and hung still. Once in three trials, plainly. Twice, maybe nothing.
He wrote all of it down, the stirring and the stillness alike, because Vance's rule was to record what happened and never what was hoped.
He worked slowly, resting between trials, and the night gave him the time. The brush moved in the gaps. In a column on the scrap he set the figures: his budget, eleven and nine and ten breaths of trickle before the tithe came due. The dagger's capacity, four breaths. The hold, thirty breaths, leaking from the first. The release, a thread of moving air felt on wet skin, strong enough to stir paper once in three tries. Small numbers. Honest ones. He leaned his weight into the desk's edge when his legs tired, and read the column back to himself, and found he was not ashamed of it.
A man could build on ten breaths, provided he admitted they were ten.
Then he turned a fresh sheet and began the drawing. He used the dagger's spine as a straightedge and worked in cross-section, the way Vance's old drafting habits worked, showing the inside of a thing that existed nowhere but on the page.
A tube of steel, two chi long, its bore no wider than his little finger, because steel gave strength cheaply and asked nothing of the qi. Behind it a chamber no larger than a walnut, walled in spirit iron thin as a coin, because the night's tests said spirit iron held what steel refused. A gate of spirit iron set against the chamber's mouth, joined to a thumb bar along the ironwood body, so the charge could be let out all at once instead of leaking away across thirty breaths. A cast-iron ball no bigger than a plum stone for the bore.
It was not the rifle. It was the question the rifle would answer first, made small enough to build from one dagger's worth of spirit iron and a few sessions of measured breath.
Across the top of the sheet he wrote the three limits, because limits forgotten became failures. Qi: ten breaths a session, a few sessions a night, no more. Material: one dagger of spirit iron, and everything else steel, wood, and what the tests allowed. Body: he could charge, count, and write, and the poison set the length of every session whether he liked the terms or not.
Along the margin he numbered the questions the sheet could not yet answer. Whether qi released quickly pushed harder than qi leaked slowly. Whether a gate could open fast enough to matter. How many breaths of charge a ball needed to travel the tube's length and strike. Each question small. Each one testable, with paper strips and wet fingertips and counted breaths, repetition on repetition until the numbers stopped moving. Tomorrow's work, and the day after's, and the day after that.
The room stayed what it was, a disciplined young smith's chamber, orderly, ink and wool and cold stone, nothing in it of Vance's world. The sheet on the desk belonged to neither life alone. The smith's hands knew what metal would forgive. The draftsman's habit knew how to put the question on paper. For the first time since he woke in this body, the night held more than endurance.
He set the brush across the ink stone and looked at what the hour made: a column of small honest numbers, a drawing crossed and recrossed with section lines, a list of tests waiting for the light. A rifle it was not. It was the measured, bounded beginning of one, written down where wishing could not inflate it. The wind worked at the lattice. The lamp burned low. Lu Feng set the spirit-iron dagger back along the south wall where it belonged. On the desk, the first schematic held its lines in the amber glow, and the work was begun, bounded and honest and small.
