Chapter 7 The First Apprentice
Sixth day of seven. Geng’s Remedies, mid-morning.
I went back the next day, and this time I came to teach.
I’d lain awake on the inn’s straw most of the night turning it, not the method, the giving of the method.
There’s a thing that happens to knowledge the moment it leaves your skull and lands in another.
It stops being yours. You can’t un-tell it, can’t recall it, can’t charge for it again.
Every clean process I’d built up the valley floor lived in exactly one head, mine, and a head is a chamber you can keep a price in.
Open it to a second head and you’ve doubled the supply of the rarest reagent I owned, which was the only reason anyone needed me at all.
And I’m about to give it away for free in a shop three streets off a square I can’t outspend.
I’d checked the arithmetic from four directions and it came out the same every time: the smart play was to keep the method locked and sell the pills.
The sum was wrong. I knew it was wrong the way I knew my father had been right and broke anyway.
And there was the other arithmetic, the legal one I kept not looking at.
The clause I’d written to make this lawful, the right to train apprentices on subjects of my own determination, was a sentence in a scroll riding east toward a desk that had not answered.
Until Wen Chao signed it or refused it, it was a proposal, not a shield.
It protected nothing yet. I was about to teach three days ahead of my own permission and bet the whole corridor that a proposal would harden into law before anyone troubled to test whether it had.
So I went back to teach.
Geng was up off his stool before I cleared the doorway, the merchant’s smile starting and stalling when he placed me. “The list-maker,” he said.
“The list-maker. I want to light your cauldron.”
Behind him a younger woman straightened from the back-room doorway where she’d been grinding something in a stone mortar, and stopped.
Thirty, maybe, with the same narrow build and the same ink under the nails, sleeves pinned back off thin strong forearms and a smear of green dye dried along one of them where she’d leaned on the dye-house wall.
She had her father’s reading-squint but none of his tiredness yet; she had the other thing instead, the thing I’d had at twenty-four behind a counter, the held-breath of someone who suspects the world is bigger than the room they’re allowed to work in and is angry about the size of the room.
“My daughter,” Geng said. “Anru. She does the grinding I can’t, my hands shake now. Anru, the man with the list.”
“You said no list,” Geng Anru said to her father, not to me. Her voice was flat and fast. “You said he was talking and nothing came of talking.”
“I changed my mind,” I said. “Talking’s done. Can I see your reagent stock and your one cauldron, and do you have a wall I can write on?”
◆ ◆ ◆
She didn’t trust me, and she was right not to, and I liked her for it.
I had Geng pull every common pill he used to brew before the wholesale floor killed it, and we laid the recipes out on the scrubbed counter, the orthodox versions, the ones the whole corridor brewed the same orthodox way and got the same orthodox yield from.
Then I asked for a stick of his label charcoal and started on the whitewashed back wall, and I taught them to see a recipe the way I’d had to invent seeing it, alone, the year I learned the system wasn’t going to hand me the answer as it handed everyone else.
“Forget the recipe as a list of steps,” I said, and drew.
“A pill’s a molecule that wants to form and a hundred ways it’d rather not.
Draw the thing you’re building, not the things you do.
” A long horizontal line. “Backbone. That’s your base reagent, the spine the whole pill hangs off.
” Circles strung along it. “Ring circles, the active groups, the part that does the healing.” Little hooks off the rings.
“Sidechain hooks, the bits that decide whether the body can use it or just passes it through.” Geng was watching the wall the way a man watches a language he half-remembers.
Anru had stopped pretending not to listen.
“This isn’t how it’s taught,” she said.
“No. It’s how it works. The teaching hides the working so the yield stays scarce.
” I tapped each part again, slower, because the wall wasn’t the lesson, the reading of it was.
“Here’s what I want you to be able to do by the end of this morning.
Not brew my recipe. Read any recipe and tell me where it’s bleeding yield.
The orthodox bone-set you’ve made a thousand times, the one the floor killed, look at it as a drawing.
” I sketched it beside the first diagram, fast, the spine and the rings and the hooks of his own cheap pill.
“Where do you lose it? Where does this fall apart?”
Anru answered before her father, which told me which of them I was really teaching. “The rings.” She pointed, hesitant, then not. “If they set in the soup, half of them form crooked and pass straight through the patient. That’s the mottling. That’s why his come out two colors.”
“That’s why they come out two colors,” I agreed, and watched Geng look at his daughter like he’d never seen her.
“You already knew the symptom. You called it bad bone-ash, or a cold day. It was never luck. It was the rings forming with nothing solid to land on. Everything I teach you this morning is one idea: give the rings a cold spine to land on, and stop losing the crooked half.” I tapped the backbone.
“Here’s the trick the orthodox method throws away.
Heat-delta.” I drew the arrow I’d drawn ten thousand times for an audience of nobody, a small barbed thing pointing up the backbone.
“Where you put your heat and where you pull it. The standard recipe ramps the whole cauldron together, even, like that’s reverent.
You don’t want reverent. You want the backbone to set before the ring circles do, so they crystallize onto a spine that’s already holding still.
Heat the base hard and early. Then, here, before the rings lock,” I drew the second mark, the one that mattered, “thermal-break. You drop the heat off a cliff. Not down. Off. Pull the fire entirely for a count, and the rings precipitate clean onto the cold backbone instead of fighting it in the soup.”
“You’ll crack the cauldron,” Geng said, the flat reflex of a man who’d cracked one.
“You’ll crack it if the iron’s thin. Yours isn’t, I looked, your iron’s old and good, that’s why I’m standing here. Pull the fire for a count of eight, not twelve. I’ll watch the first one with you.”
◆ ◆ ◆
We lit it.
I made Geng do the brewing with his own hands, which was the whole point, and stood at his shoulder doing nothing but reading the cauldron out loud.
If I do it for him, he learns I’m a wizard.
If he does it, he learns it’s a method. His hands shook on the heat-stone and steadied once they had a job.
We used his orthodox bone-set recipe, the cheap one the floor had killed, with the dye-house’s madder sludge worked in as the iron-binding base, because I’d had Anru run two streets to the dye-vat at dawn with a bucket and a face that dared anyone to ask why.
“Backbone’s setting,” I said, hand flat over the rim, reading heat off the air the way I’d taught myself to read a reserve. “Hold it. Hold it. Color’s going from milk to the color of weak tea, you see it? That’s the spine locking. Now, Geng, now, pull the fire.”
He hesitated. Of course he did. Forty years of every master telling him steady heat was virtue, and a stranger telling him to yank it off a setting pill.
His daughter said, “Father,” one word, sharp, and he pulled the firepan clear, and the cauldron’s roar dropped to a tick of cooling iron, and for a count of eight nothing happened, eight seconds of an old man’s whole training screaming that he’d just ruined a brew, and then the surface of it went from weak tea to something with light caught in it, a fine bright precipitate dropping through the cooling slurry like the first frost forming on a window.
Geng made a sound I’d made myself once, behind a counter, alone, the night I first understood the cauldron wasn’t magic, just chemistry that hadn’t been written down honestly.
We pulled eleven good bone-set pills out of a cauldron that had given him seven on his best orthodox day, and they were a grade cleaner besides, denser, the ring-color even straight through instead of mottled.
Eleven for seven. On free madder he’d been pouring in the river for years.
Anru held one up to the window light and turned it, and her flat fast voice had something under it now.
“This is a Pavilion pill. This is better than a Pavilion pill, and it cost us the firewood.”
She set it down very carefully, the way you set down a pellet you are afraid to let yourself want.
“The cooper’s wife,” she said, not to me, to the pellet.
“Two winters ago. Lung-rot. The hall had the pill for it across the square, and she had half of what they asked, and Father brewed her the honest version of what he could afford instead, and the honest version was not strong enough, and we both knew it was not strong enough while we watched her take it.” Her jaw worked once.
“There was a better pill in reach the whole time and a wall of price between her and it. You just put the better pill in my father’s hands for the cost of firewood.
So do not say it cost us the firewood. I know what it cost. It was not the firewood and it was not us. ”
“It cost you the firewood and a count of eight,” I said. “And the heat-delta arrow on your wall. That’s the whole price. Brew it like that from now on and undersell the hall on the honest end again.”
