There was a faint metallic taste in the air, like biting down on a copper coin. I stood at the registration desk, studying a row of faintly glowing jade rings beside it — monitoring rings, which, once worn, could not be freely removed. This was the Resonance Institute's Grade E sector, but it looked more like a hospital crossed with a prison: walls of smooth grey-white stone, polished enough to reflect; jade panels set into the corridor walls at regular intervals, their surfaces dense with inscribed runes, gold thread tracing their edges in a slow, continuous current. Coming in, I'd glanced at the herb garden through the window and estimated the medicinal reserves by seventeen years of apothecary habit — enough for approximately three hundred people for three months — then returned my attention to the notice board.
The notice board held a sheet titled *Grade E Research Subject Conduct Regulations*. Article Three, printed in red: *Cultivation is prohibited without authorization. Violation will result in forced closure of the aether-resonance channel.*
"You're reading that too?"
The voice came from beside me. I turned. A girl stood there, her sleeve cuffs dusted with dried mud, a small white flower — no larger than a thumbnail — pinned in her hair. She spoke with her hands moving symmetrically at her waist, as though measuring something.
"I'm Lin Wanzhao. Botanist." She smiled — the corners of her mouth moving first, her eyes catching up half a beat later. "They brought me in because I found a plant that doesn't appear anywhere in the Heavenly Dao fate-thread registry. Genetic mutation, they called it. The plant was growing deep in an abandoned ore shaft — it should have died long ago by any reasonable calculation. It hadn't. The pattern of its leaf veins is completely unlike any standard spirit herb."
I looked at the mud on her sleeve. "That sounds like me," I said. "I'm the mutation in the human population."
Lin Wanzhao laughed out loud. The small white flower trembled in her hair. "You say what you mean." She leaned closer and lowered her voice. "Though here, that's not a bad thing. Grade E is actually the lenient tier — communal housing, one approved outing per month, as long as you wear this." She pointed at the monitoring ring. "Grade D and above is worse. Core Formation cultivators get individual chambers, one exit per year. Higher than that — Nascent Soul is full confinement. Spirit Transformation is permanent confinement. The celestial-born First Seat's quarters are reportedly under restricted-zone sealing. Theoretically, even Companion Bond exemption doesn't apply."
"Companion Bond exemption?"
"If a Companion Bond is formed and the resonance verification passes, the radiative damage drops below the safe threshold." Lin Wanzhao sketched something in the air with her hands. "The verification is nearly impossible to falsify — a failed attempt injures the soul. So most people would rather stay confined." She paused. "For us Grade E subjects, it's mainly an observation period. Three months. No cultivation during that time — they need to confirm our 'mutations' won't trigger aether-resonance destabilization."
The registrar behind the desk handed me a jade ring. I took it. The moment it touched the skin of my wrist, a faint vibration passed through — something scanning beneath the surface. The ring cinched itself closed automatically, a band of pale blue light tracing its edge.
"Follow me. I'll take you through the research sector." The registrar was a middle-aged cultivator, his tone as flat as a list being read aloud. "The celestial-born First Seat is not in the Grade E main sector today. Your timing is fortunate."
The eight of us followed him into the corridor. It was long, lined on both sides with sealed stone doors, each marked with a number and carved runes. The metallic quality in the air grew heavier. Breathing, I registered a mild pressure in my chest — the sensation of moving through water. Lin Wanzhao walked beside me, her fingers working unconsciously at the dried mud on her cuff.
A few doors down, the people ahead began to falter.
First: a young man in a blue-grey changshan. His steps lurched. He reached out and caught the wall. Then the girl beside him flushed red, fine beads of sweat appearing at her hairline. The floor vibrated — a steady frequency that climbed from underfoot up through the ankles, leaving them numb.
"What's happening—" someone rasped.
The young man pressed his hand to his head and sank down, a suppressed sound escaping his throat. The monitoring ring on his exposed wrist had shifted from blue to a sharp, alert red. The registrar spun around. His face had changed. "Back up. Everyone back up—"
He was too late. Someone else collapsed, their body striking the stone wall with a dull impact. The vibration intensified. The runes on the walls flickered on and off, like a loose connection. I stood where I was and watched, one by one, as those around me bent double, crouched, crumpled — the flush spreading across their skin with speed, as though something invisible was burning through them.
I felt nothing.
The pressure that had been sitting in my chest since I entered the corridor had, if anything, eased slightly. I looked down at my hands. Normal color. The monitoring ring was still pale blue. I made a fist. My fingers moved without resistance.
Lin Wanzhao was sliding down the wall. I crossed to her and caught her arm. The monitoring ring at her wrist was red. In the few seconds I held her, the red faded — gradually back to pale blue. She didn't notice.
I looked up. At the far end of the corridor, a figure had appeared.
He stood there, upright, nearly a full head taller than most people. The light from the jade panels along the walls fell across him — not soft, but a cold metallic gold, like liquid metal in motion. He wore a dark ink-grey changpao, the fabric showing fine texture in the light — not decorative pattern but formation arrays woven into the cloth itself. His hair was gathered at the crown with a jade pin, a few loose strands falling along the side of his neck.
He stopped. He looked at the people collapsed on the floor.
His gaze moved across them — the ones crouching, the ones braced against walls, the ones down entirely — and came to rest on me.
I was the only one still standing.
The corridor was very quiet. Quiet enough that I could hear my own breathing. In, out. In, out. Normal rhythm.
I was still holding the registration form I'd just collected. The corner had been creased in my grip, the edge curling. He walked toward me. The young man in blue-grey at his feet sank another inch. One step. Two. Three — then he stopped.
I measured it later. Exactly three feet.
He looked at me.
I looked at him. Not at his full face — my gaze stopped at the edge of his collar, where gold resonance marks extended from beneath the fabric and moved slowly beneath his skin. The marks gave off a cold light. Close up, that light pulsed faintly — the rhythm of something breathing. His complexion was pale, the particular pallor of someone long kept from sunlight. His lips were pale too, nearly white.
"You're unaffected?" he said.
Not loud. Very clear. Even spacing between each word.
"I'm unaffected," I said.
He looked at me for a long time. His gaze settled on my face, and his eyes held nothing — like something not quite in focus. The only sounds left in the corridor were the strained breathing of those on the ground and the faint hum of the runes flickering on the walls. The resonance marks at his neck slowed — and in the same instant, the runes on the corridor walls slowed with them, their frantic flickering settling into a gentler pulse. He didn't notice it.
I did.
He spoke. His voice was low.
"Fate-blank."
I hadn't yet worked out what he meant by that when there was movement behind me. Lin Wanzhao pushed herself off the ground, arms shaking. Her face was white, but she could stand. The jade ring at her wrist had returned to pale blue. She looked at the man. Then at me. Her lips moved and produced nothing.
The registrar struggled upright too, and bent toward the man. "First — First Seat — how did you—"
"Passing through." The man's gaze finally left my face. He scanned the people on the floor. "Take them to the medical chamber. Early-stage aether erosion. There's still time."
The registrar acknowledged the order immediately and began helping people up one by one. Lin Wanzhao came to my side and grabbed my wrist — her fingers cold, still faintly trembling. She brought her mouth close to my ear and said four words under her breath:
"He is reading fates."
I looked at her. Her eyes were level. The specific levelness of someone confirming what they already suspected. She let go of my wrist and went to help the young man in blue-grey who was still crouched on the floor.
I looked back toward the far end of the corridor.
The man was still standing there. Three feet. He hadn't moved closer. He hadn't left. He was looking at me again — this time at my wrist, the one with the monitoring ring. Still pale blue. Against a corridor full of red alerts, it was conspicuous.
I raised my hand and looked at the ring. Then at him.
"Is there somewhere to eat nearby?" I asked.
The outer edge of his brow dropped a fraction — a very small movement. Then it was gone.
"Yes," he said. "East corridor, end of the hall, turn left."
"Thank you."
I folded the creased registration form in half, tucked it into my sleeve, and turned east. My footsteps struck the flagstones and sent clear echoes down the corridor. The runes at the far end were still red. He had not left.
I didn't look back.
The dining hall was at the end of the east corridor, a small placard hanging at the door, the characters neat:
*Spirit Meal Set — Grade E Research Subjects: Complimentary.*
I pressed my fingers against the herb packet in the depths of my sleeve pocket.
*Master said: brew it yourself.*
Spirit Meal Set — Grade E Research Subjects: Complimentary. I counted the herb packets remaining in my sleeve. Eleven days' worth.
That was enough.
