The pain was a constant, throbbing echo in the hollow where her right eye used to be.
Lin Xiao lay on the cold stone floor of her cell, a rough bandage soaked in medicinal paste pressed against the ruin of her socket. The cavern's healer—a silent, gaunt man with fingers like bird bones—had stitched the torn flesh and packed the wound with herbs that smelled of bitter earth and decay. "It will fester or it will heal," he had said, his voice devoid of empathy. "If you live, you keep the patch. If you die, I take it back."
Survival. It was the only law she understood now, carved into her bones over the past weeks. But this… this was different. The world had narrowed, literally. Her depth was gone, flattened into a single plane of vision. The left side of her face was a landscape of swollen, fiery agony. Every heartbeat was a drum of pain.
But beneath the pain, colder and harder, was memory.
*Gao's brutish face, twisted in a sneer. The shock of impact as his thumb dug deep, past bone, into soft tissue. The world dissolving into red, then black. The feel of the rock in her hand. The wet, final sound it made against his skull.*
She had killed. Not in the anonymous chaos of a training brawl, but face-to-face, with intention. And the overseer had looked at her with something akin to approval. *"The whetstone has broken. The blade remains."*
A week passed in a blur of fever and fitful sleep. On the eighth day, the pain receded from a roaring fire to a dull, persistent ache. The healer changed her bandage, revealing the ruined socket now covered by a puckered, angry scar. He handed her a strip of dark, rough-spun cloth.
"Cover it. The sight unsettles the others."
She tied the patch in place, the world narrowing further still. When she stood, the floor seemed to tilt. Her balance was off, her perception skewed. She stumbled against the wall, breathing hard.
*Adapt or die.*
She repeated it like a mantra. She would learn this new way of seeing. She would make it her strength.
That afternoon, the overseer gathered the survivors of the latest "culling" spar. Of the twenty new recruits, twelve remained. Lin Xiao stood among them, her posture straight despite the dizziness. Beside her, she felt more than saw Nie Luo's quiet presence. He had survived his own match with a bruised rib and a cut above his brow, but his eyes were clear, watching everything.
"You have passed the first threshold," the overseer barked, his scarred face impassive. "You have shed blood. Your own, or another's. This grants you a privilege." He gestured to a hulking guard who pulled open a heavy iron door set into the cavern wall, one that Lin Xiao had never seen used. "Beyond this door lies the Archive. A repository of… discarded knowledge. You may enter for one hour each week. You may not remove anything. What you learn there is your own affair. Let it make you sharper, or let it be your distraction. I do not care."
One by one, the survivors were ushered through. Nie Luo gave her a barely perceptible nod before he disappeared inside. When it was Lin Xiao's turn, she stepped across the threshold and into another world.
***
The Archive was not a library as she had imagined from her mother's tales. There were no polished shelves or scroll racks. It was a natural cavern chamber, vast and damp, its ceiling lost in shadow. The air was thick with the smell of mildew, old parchment, and stone dust. Makeshift shelves—planks laid across jagged rock formations—were crammed with scrolls, loose folios, and even stone tablets. Many were water-damaged, torn, or crumbling. Piles of discarded texts lay mouldering in corners. The only light came from a few sparse, faintly glowing moss patches on the walls and a single shaft of pale grey light from a crack high in the ceiling—the barest hint of the outside world.
It was a graveyard for secrets.
A few other trainees were already there, moving with the wary silence of scavengers. She saw the hulking boy who had broken his opponent's arm, cautiously examining a diagram of a bear-hugging technique. A wiry boy with a split lip was tracing characters on a water-stained page.
Lin Xiao moved deeper into the chaos, her single eye struggling to adjust to the gloom. Her feet were silent on the uneven floor, a habit born of survival. She ran her fingers over cracked leather scroll cases, their inscriptions faded. She saw titles in a dozen different styles: *"The Meridian-Shattering Fist of the Stone Tiger Sect," "Five-Poison Needle Treatise," "Discourse on the Ghost-Walking Step."*
They were techniques from sects she'd never heard of, captured as spoils of war, traded, or stolen. This was the Midnight Blade Castle's true treasure trove—not gold, but the plundered knowledge of their enemies and allies alike, deemed imperfect, heretical, or simply too dangerous for formal study, but too valuable to burn.
Her heart beat faster. This was opportunity. This was a weapon her father could not control.
She found a secluded niche behind a towering stalagmite, where the light from the moss was a little brighter. There, piled haphazardly, were several scrolls on anatomy and Qi flow. She unrolled one carefully. The diagrams were intricate, showing the body's meridian network. Another, more fragmented, discussed "pressure points of ephemeral effect," targeting not the body, but the flow of energy itself to cause paralysis or internal disruption.
The concepts were alien, dangerous. They spoke of attacking from within, of severing the connections that made a body move, a heart beat, a mind command Qi. It was a ruthless, surgical form of violence. A ghost's violence.
A whisper of movement made her look up. Nie Luo stood there, holding a small, rolled parchment.
"You look… focused," he said softly, his voice barely disturbing the thick air.
"There is knowledge here," she replied, her own voice hoarse from disuse. "Not just brute force."
He nodded, crouching beside her. He was a year older, fourteen to her thirteen, with a lean, observant face and dark eyes that missed little. His black hair was tied back simply, and the new scar above his brow gave him a slightly severe look. "I found a treatise on basic trap detection. Du Kang will want to see it." He gestured with his chin toward a smaller boy with clever, darting eyes who was enthusiastically examining a scroll full of mechanical diagrams. Du Kang waved back with a grin that didn't quite reach his nervous eyes.
"We should share what we find," Nie Luo continued. "Three sets of eyes are better than one. Especially now." His gaze flickered to her eyepatch, not with pity, but with cold assessment. "You will need to compensate. These texts on anatomy… they might hold a key. Understanding how the body is connected could help you predict movement in your new field of vision."
His practicality was a balm. He didn't offer sympathy; he offered a strategy.
"And this," he said, unrolling the parchment he held. It was a crude, hand-drawn map of the cavern complex, with notes on guard patrols and supply schedules. "It was tucked inside a manual on logistics. Someone else tried to plan an escape once."
They shared a look that spoke volumes. Escape was a dream for another day. For now, survival meant arming themselves with every scrap of knowledge they could find.
Lin Xiao returned to her scrolls with renewed determination. As the hour waned, she pieced together fragments from three different sources. One mentioned a "Severing Palm" technique from a defunct sect called the "Veiled Dagger Brotherhood," designed to disrupt tendon and ligament with a precise burst of internalized Qi. Another, a philosophical text on "The Illusory Self," spoke of the mind's control over the body's energy, and how that control could be… interrupted. A third, a badly damaged scroll with singed edges, had a passage that made her blood run cold:
*"…and thus the highest mastery is not over the flesh, but over the will. The *Soul-Chain Art* of the Western Reaches speaks not of binding the body, but of anchoring to the consciousness itself, turning the enemy's own spirit into his cage. Such arts are forbidden, for they leave no scar upon the skin, yet shatter the palace within…"*
The words were cryptic, more allegory than manual. But the concept lingered—a form of attack that targeted the very seat of control, the will. It was a terrifying, intimate form of power. She committed the phrase "Soul-Chain" to memory, a strange and unsettling piece of a puzzle she didn't yet understand.
As the guard's call echoed through the chamber—*"Time! Out, now!"*—Lin Xiao carefully re-rolled the scrolls, marking their location in her mind. She had found her path forward in this abyss.
The cavern's darkness no longer felt just like a prison. It felt like a womb, and she was forging herself anew within it, one stolen secret at a time.
