Elder Sun's study had forty-two books.
Chen Yi knew this because he had counted them on the first visit, catalogued the titles on the second, and was now, on the third visit, sitting in the low chair across the desk with the third volume open to the appendix page while Elder Sun watched him take notes.
He was not supposed to be taking notes. Elder Sun had not said he could take notes. But Elder Sun had also not said he couldn't, and the silence had persisted long enough that Chen Yi had decided to treat it as permission.
"You write quickly," Elder Sun said.
"I don't need to write at all. I remember everything I read." He kept writing. "The notes are for you."
Elder Sun blinked. "For me."
"In case something goes wrong and someone needs to continue the work."
A pause.
"You're ten years old," Elder Sun said, for what was becoming a recurring observation.
"I know." Chen Yi turned a page. "What do you know about the Abacus of All Things?"
The study went very still.
Not quiet — it was already quiet. Still, in a different way. The way places went still when a word was spoken that had weight.
Chen Yi looked up.
Elder Sun's face had changed. Not much — the man was controlled, whatever else he was. But around the eyes something had shifted. Recognition, perhaps. Or the cousin of recognition. Something that knew the name.
"Where did you read that," Elder Sun said.
"I haven't. I calculated to it." Chen Yi set down his pen. "The Compendium's appendix describes the Unified Root cultivation as requiring a mind that doesn't forget, doesn't favor, doesn't fear contradiction. It says in three thousand years no such mind has been documented." He looked at Elder Sun. "It doesn't say why such a mind is being sought. Most techniques don't require a specific type of mind — they're adapted to the cultivator. This one requires the cultivator to be adapted to it. Which means it was designed for something. Something that needs this specific configuration."
Elder Sun said nothing.
"There are three references in the classical texts to an ancient object that optimizes cultivation rather than granting it. All three describe it as primordial — existing before the first cultivators. All three describe it as seeking. Two of the three use the word calculation." Chen Yi folded his hands. "I don't know what it is yet. I'm telling you because if I'm right about what my cultivation is building toward, you should know."
The study held them both.
Elder Sun was looking at him with the expression he'd had on the first day — the one Chen Yi couldn't fully categorize. Like a man seeing something through water. Present but slightly displaced.
"I was a sect elder," Elder Sun said. "Before I came here."
Chen Yi nodded. He'd known — the evidence was in the book collection, the vocabulary, the qi-sight used reflexively in the manner of the trained rather than the naturally gifted.
"I retired because I made a mistake." He said it flatly, without performance. A man stating a fact he had stopped flinching at. "Forced a breakthrough in a promising student. She died. I resigned my position, came here, and decided to spend whatever years I have left being useful to a village that needed a cultivation advisor and had no budget for one." He paused. "I have, in forty years of cultivation study, heard the Abacus of All Things mentioned twice. Both times by people who died shortly after."
Chen Yi absorbed this.
"I'm not going to die shortly after," he said.
"The other two also believed that."
"The other two presumably didn't have three weeks of Unified Root cultivation and a working theory about why the technique is actually survivable." He picked up his pen. "I'm not dismissing the concern. I'm saying the evidence is insufficient to establish a pattern, and the nature of the danger in both cases is undocumented."
Elder Sun stared at him.
"You're infuriating," he said. But it came out sounding almost like respect.
"I've been told." Chen Yi turned to the next page. "Can you tell me anything more about what happened to the other two? The context of when they mentioned it, what they were doing, whether their cultivation path was unusual?"
Elder Sun was quiet for a moment.
Then he reached into his desk drawer and withdrew a small, very old journal.
He set it on the desk between them and did not open it.
"I'll tell you what I remember," he said. "Not from that. Not yet." He folded his hands over the journal. "You earn the rest."
"By doing what?"
"By surviving the examination. By continuing the cultivation. By being here in a year for me to tell it to."
Chen Yi looked at the journal. Then at Elder Sun.
"That's a reasonable condition," he said.
"Thank you for your approval," Elder Sun said dryly.
Chen Yi almost smiled.
He picked up his pen and went back to his notes, and Elder Sun refilled both cups without being asked, and outside the morning moved through the village the way mornings did in places that had decided to keep going, which was quietly, and without hurry, and with a kind of stubborn grace.
