Chapter 1: The Servant of Crescent Moon

The stone wall was cold under Wei Mao's palms.

It was always cold — the outer halls of Crescent Moon Sect never caught the sun, built as they were on the northern face of Mount Cangwu, deep in the shadow of the peak's broad shoulder. Even in summer, the disciples who passed through these corridors pulled their robes tight and hurried along, eager to be somewhere warmer, somewhere the qi was richer and the light kinder.

None of them glanced up.

That was fortunate, because Wei Mao was currently pressed flat against the ceiling, a bucket of grey soapy water hanging from a hook he'd wedged between two ceiling stones, his body defying every reasonable expectation of gravity.

He had been doing this since he was four years old. Crawling on walls. Sleeping wedged into corners near the rafters. Seeing in darkness as though the night itself refused to keep secrets from him. As a child in the orphanage on the outskirts of Liusha Town, the other children had called it unnatural. The matron had called it cursed. One travelling cultivator who'd passed through — a core disciple of some minor sect whose name Wei Mao had never learned — had taken one look at his amber-gold eyes and called it something else entirely.

"Demonic bloodline," the man had said, backing away as though Wei Mao were a lit torch held near dry hay. "Ghost Cat Constitution. Don't bring that near me, boy."

Wei Mao had been seven years old.

He was nineteen now, and he'd heard the words so many times they'd worn smooth like river stones. Ghost Cat Constitution. Demonic bloodline. Not suitable for cultivation. Please leave before we call the sect elders.

Four sects. Four rejections. All before he'd turned seventeen.

Crescent Moon Sect had been his fifth attempt, and they hadn't exactly accepted him either. What they'd done was more pragmatic: they'd seen a boy willing to scrub floors, clean walls, haul water up the mountain, and carry loads that required three people normally — all without a single spirit stone in wages — and decided that was useful enough to tolerate. They hadn't given him a disciple robe. They hadn't given him access to the cultivation halls or the library or the sparring grounds. What they'd given him was a broom, a bucket, and the northern outer hall.

That had been two years ago.

Wei Mao wrung out the rag against the ceiling stones — he'd learned through painful experiment exactly how much water a ceiling could tolerate before it dripped back onto him — and worked the mildew from between the blocks in long, practiced strokes. The sect's outer hall hadn't seen proper cleaning in what smelled like decades. The stone breathed out damp and age and the faint mineral tang of old spiritual energy long since dissipated. There was nothing useful left in these walls. Just history and rot.

He'd cleaned perhaps three feet of ceiling when his fingertips felt it.

Not mildew. Not the rough grain of mountain stone. Something smoother, deliberately so, pressed flat against the ceiling and painted over — once, twice, perhaps a dozen times across however many years — to hide it. His fingers, sensitive enough to feel a spider's thread in complete darkness, traced the outline without him consciously deciding to.

A seam. A rectangular seam, perhaps half a foot long and four inches wide, worked with the precision of a craftsman rather than a mason.

Wei Mao's amber eyes narrowed.

He shifted his weight carefully, redistributing himself across three points of contact instead of two, and worked his fingernails into the seam. The paint was thick — truly thick, layer upon layer of the pale grey mixture the sect used on all their outer walls — and it fought him. He wasn't in a hurry. Nobody came to the northern outer hall before the evening meal, and the evening bell was still two hours away. He worked at it steadily, the way he worked at everything: without drama, without rushing, with the patient persistence that was either his greatest virtue or, as the other servants informed him with frequency, his most irritating quality.

The last layer of paint cracked away in a sheet.

Beneath it was jade.

Not the cheap quarried jade the sect used for minor arrays — this was the real kind, the deep translucent green that seemed to hold its own light, carved into a tablet no larger than a man's palm and etched with characters so fine they might have been made by a needle. Wei Mao's eyes moved across them automatically, grateful now for the one genuine gift his cursed constitution had given him: in near-total darkness, pressed against a ceiling two stories up, he could read every single word.

Nine Lives Immortal Scripture, the first line read. Recorded by the Shadowcat Demon Sovereign in the ten-thousandth year of the Shattered Heaven era. For the inheritor whose blood remembers the void between walls. For the one who crawls where others cannot stand.

Wei Mao stared at the tablet for a very long time.

His bucket dripped once, softly, onto the stone floor below.

Then, with the extreme carefulness of a person who has survived this long entirely through caution, he worked the jade tablet free of the ceiling, tucked it into the inner pocket of his rough servant's robe, painted over the cavity with a spare brush and the grey mixture he kept in a small pouch precisely for situations — well, not precisely for this situation, but for touching up scuffs and scratches that might draw the head servant's attention — and finished cleaning the last three feet of ceiling as though nothing at all had happened.

He came down from the wall as the evening bell rang, collected his bucket, and walked with measured steps back to the servants' quarters.

His heart was doing something it had never quite done before: hammering with something that was not quite fear.

It felt like it might be hope.

The servants' quarters of Crescent Moon Sect were a long stone building pressed against the mountain's flank, divided into narrow cells just large enough for a sleeping mat and a small chest. Wei Mao's cell was at the far end, which the other servants had given him because it was furthest from the latrine and had a gap in the window frame that let in a knife of cold air in winter. They considered it the worst room.

Wei Mao had considered it the best room from the moment he saw it, because the window gap was exactly large enough for a cat — or a person with extremely good spatial awareness — to pass through. He didn't use it often. But he liked knowing it was there.

He sat on his mat with the jade tablet in his hands, the door latched, and read.

The Nine Lives Immortal Scripture was not, as he'd half-feared, gibberish or a trap or the sort of false manual that unscrupulous cultivators sometimes planted to injure those without the sense to verify authenticity. It was structured and coherent in the way that only genuine cultivation texts were — layered, precise, its terminology consistent across every section. He recognised some of the foundational concepts from the scraps of cultivation theory he'd picked up over two years of quietly listening at walls he was supposed to be cleaning.

The core premise was this: most cultivation techniques treated the cultivator's body as a vessel to be filled with spiritual energy, slowly refining it from a weak mortal container into something capable of holding immortal power. The Nine Lives Immortal Scripture treated the cultivator's body as a predator — and specifically, a predator that had already eaten something divine.

The Ghost Cat Constitution, the text explained with a matter-of-factness that made Wei Mao's breath catch, was not a curse. It was not demonic corruption. It was an inheritance — a sliver of bloodline memory from the Shadowcat Demon Sovereign herself, who had not died but dissolved, distributing fragments of her essence into the bodies of mortals across ten thousand years, waiting for one who was both worthy and stubborn enough to find the scripture.

The constitution was a seed, the text said.

The scripture was water.

Wei Mao read through the night without noticing, his amber eyes bright in the darkness, and by the time the dawn bell rang he had finished the first section — the foundation of the First Life — and had already begun to feel the qi in his body doing something it had never done before.

Moving toward him instead of away.
