In this world, there are being who exist by harming other beings called demons. They exist in many forms.
Blood demons that drain the living of their blood and refine it through Tempering. Bone demons that hollow out bodies and leave them shapeless. Flesh demons that consume everything. Soul demons that devour consciousness and leave walking husks. Plague demons, venom demons,desire demons, flame demons, verdant demons — each one a different horror, each one a different kind of way of survival.
But the most common type — the one ordinary people are most likely to encounter, is the shade demon.
A shade demon has no body of its own. It is a soul without flesh — wandering, formless, hungry. Without a host, it fades. The weak ones dissipate in days. The strong ones can linger for weeks, searching.
Once it finds a host, it doesn't possess. It nests. It weaves its soul into the host's spiritual channels and settles alongside the host's consciousness. At first, they coexist the host is gains knowledge and skills beyond thier understanding, they become a genius overnight. The host might feel a strange presence, a voice that isn't theirs, thoughts that don't belong. They dismiss it. Stress. Illness. Bad sleep.
Then the shade feeds.
Slowly. Gently at first. A sip of spiritual energy here, a thread of cultivation there. The host feels fatigued. Memory gaps. Moments they don't remember. The shade hides the damage — feeds from the inside, leaves the outer structure intact so no one notices. Healers find nothing. Everything looks normal on the surface.
Over months, sometimes years, the feeding deepens. The host's cultivation stagnates, then declines. Their meridians dim. They start forgetting — not small things, but important things. Names of people they've known for years. Techniques they mastered decades ago. The shade consumes spiritual memory along with energy. Every piece it takes carries fragments of the host's self.
The body fails. Hair greys. Skin thins. Eyes dull. They look like they're aging decades in months, but they're not aging — they're being eaten alive. And through all of it, the host's soul is still there. Still aware. Watching through dimming eyes as the shade wears their face, speaks with their voice, lives their life.
Then the host dies. The body collapses. The shade has seconds to find a new host before it dissipates. If no one is nearby, it dies with the body — starved, exposed, pulled apart by the emptiness it created.
If someone is nearby, it jumps. And the cycle begins again. But there is an exception if the host forms a deal with the host before possession then the host may be able to coexist with the shade but has to hunt for it. The host then gains abilities beyond thier cultivation.
The only reliable way to detect a shade demon is a soul-mirror — an artifact that reveals the true soul inside a body. If the reflection doesn't match the face, it's a shade. But soul-mirrors are rare. Only the major demon-slaying sects possess them, and even those sects keep them under heavy guard, distributed to elders and hunting captains, never handed out freely. A small hunter team has no access. An independent cultivator has none. A mid-sized sect might own one, maybe two, brought out only when shade suspicion is formally raised.
Which means most shade demons go undetected for their entire feeding cycle. By the time someone realizes something is wrong with a person, the shade has been feeding for months. Sometimes years. The person standing next to you might be wearing a shade, and you'd have no way to tell.
This was the type of demon people thought Di Yusheng had been possessed by.
Ye Luoxue crouched in the shadow of the sect entrance wall, Yusheng beside her. The corner was narrow, dark, overlooked by no one. Her bystander field did the rest — two figures pressed against stone, invisible to anyone not actively searching.
She watched the entrance. The evening light was thin and grey. A few disciples passed in the distance, heads down, going about their business. Nothing unusual.
Then the old man appeared.
He came from inside the sect, walking with the careful, measured steps of someone whose body wasn't as strong as it used to be. He stopped at the entrance and stood there. Hands at his sides. Eyes on the path ahead. Waiting.
She glanced at Yusheng. His face was blank.
Minutes passed. The light dimmed further. Then a figure appeared on the path — a child. Small, slight, no older than ten. He walked with the casual confidence of someone who knew that nothing in this place could threaten him. His robes were plain, unremarkable, but the way he carried himself made the plainness look like a choice rather than a limitation.
Elder Han bowed. Just slightly — a dip of the head, respectful but not subservient. The boy didn't acknowledge it. Didn't even look at him. He just walked past and stopped a few paces ahead, scanning the sect entrance like he was assessing a building he was considering buying.
Luoxue's eyes narrowed. She pulled up the system.
"Scan him."

[Scan Result]
Name: Lin Xue
Age: 10
Cultivation: Mid Foundation Establishment
Classification: Regressor
Status: Active quest — eliminate target from previous life.
Note: Subject has returned from death. Carries knowledge of future events. Hostile intent directed at a specific individual. Not currently aimed at the host or any designated figure.
Luoxue read it carefully.
A regressor. Someone who had died and come back. A protagonist who carried the memory of another life and had returned to change something — kill someone, save someone, take something that was taken from him. Mid Foundation Establishment at age ten. Either he'd been cultivating since birth in his previous life and carried the foundation forward, or his regression had come with advantages she couldn't see.
The system wanted her to observe. Three hundred surveillance value for simply watching him enter the sect. But this time she intended to do more than watch.
She opened the Surveillance Exchange. Found what she was looking for — a basic bow, functional, no special properties. Cheap.

Surveillance value-10
Item acquired: Bow (standard)
Item acquired:arrow (standard)
The bow materialized in her hands. She held it out to Yusheng.
"Fire it at the boy."
He looked at her.
"Just do it something interesting will happen. Aim for his direction. It doesn't matter if you hit — your cultivation is too low to hurt him if that's what you're worried about."
Yusheng took the bow. He turned it over in his hands once, feeling the weight. Then he nocked an arrow.
Luoxue watched. This was a test — not of Yusheng, but of the system. How does it respond if i bring someone who doesn't exist to use one of it's bows to attack? Is she penalised? Does it count as her attacking? Is it ignored it entirely?
Yusheng raised the bow.
He aimed.
Not at Lin Xue.
Yusheng was turning — slowly, deliberately, the bow tracking away from the boy and toward the old man standing at the entrance. Elder Han. Still waiting. Still facing forward. Unaware.
He pulled the string back. The bow creaked. His Qi moved — everything he had, every thread of cultivation energy in his body, flowing down his arms and into the arrow.Every drop of Qi he possessed, concentrated into a single point.
He was aiming at his forehead.
Luoxue saw it. "Yusheng —"
He didn't look at her.
He breathed in. Deep. Slow. The kind of breath that isn't preparation for a shot — it's preparation for what comes after. The kind that a person takes when they're standing at the edge of something and the only way forward is down.
He let it out.
And something settled. His shoulders. His hands. His breathing. Everything that could shake stopped shaking. Everything that could hesitate stopped hesitating. The breath left him and what remained wasn't doubt, wasn't fear, wasn't grief — it was the quiet, fixed certainty of someone who had already made peace with being wrong.
He released.
The arrow crossed the distance in a heartbeat. Elder Han had no time to react. No Qi barrier to stop it. No awareness that it was coming. The arrow struck him dead center in the forehead and punched through the back of his skull with a sound like a wet crack.
Elder Han dropped.
He didn't fall gracefully. He collapsed — knees buckling, body folding, face hitting the stone path. The arrow shaft protruded from his forehead like a crooked finger. Blood pooled beneath his head, dark and spreading.
Lin Xue spun around. His eyes went to the arrow wound. To the body. To the blood.
"Ha."
The word was quiet. Not shouted. Not panicked. Just a flat, annoyed — the sound of someone who can't believe what just happened.
He drew his sword. The blade was plain steel, unremarkable, but the Qi running through it made the air hum. He stepped forward and drove the sword down through Elder Han's skull — through the arrow wound, through bone, through brain.
The body jerked.
And something moved.
It came from the the head. A dark shape, writhing, pulling itself free from the ruin of Elder Han's body. It was formless, shifting, a mass of shadow and malice that had been wearing a human body for so long it had forgotten its own shape. A shade demon. Torn from its host by the violence of the death, struggling to escape, reaching for anything — anyone — nearby to nest inside.
Lin Xue's sword came down again. The blade, charged with Qi, cut through the shade like fire through paper. The demon shrieked — a sound that wasn't audible but was felt, a vibration in the chest and a pressure behind the eyes — and then it was gone. Shredded. Annihilated. Nothing left but a wisp of darkness that dissolved into the evening air.
Lin Xue pulled his sword free. Flicked the blood off the blade. Then he turned and looked toward the sect entrance wall.
Toward the corner.
Toward them.
His eyes were steady. Calm. The eyes of someone who had done this before and would do it again.
Luoxue didn't move. Her bystander field was still active — she knew he couldn't see her clearly. But he was looking in the right direction. He'd tracked the arrow's path.
She glanced at Yusheng.
He was calm.
Not the blank calm from before. Something different. His shoulders had relaxed. His breathing was even. The tension she'd seen in him since she'd met him — the coiled, waiting stillness — had loosened. Just a fraction. Just enough.
He looked at Elder Han's body on the ground. At the blood. At the space where the shade had been.
Then he looked away.
Luoxue studied his face. There was no grief. No horror. No regret. There was something quieter — a settled feeling, like a question that had been asked a long time ago and had finally been answered.
She didn't understand what she was looking at. Not yet.
For that to happen we have to turn back time
Five years ago.
Elder Han walked towards the cliff at a place known as the black reed ridge.
A place no one went because there was no reason to go there. Nothing to find. Nothing to take. Just emptiness and height and the promise of a very long fall.
He was going to jump.
He had discovered it three days ago. The shade inside him. He'd been feeling it for months — the fatigue, the memory gaps, the sense that something was sitting in the back of his mind watching through his eyes — but he'd dismissed it. Old age. Overwork. The slow decline of a cultivator who'd never broken past the barrier he needed to break past. Normal explanations for something deeply abnormal.
Then he'd tried to meditate and felt it. A presence. Wrapped around his spiritual channels, nestled into his meridians, feeding. Gently. Patiently. Drinking his cultivation one sip at a time.
He was being eaten.
And the thing eating him was patient. It would take months. Maybe years. He would feel himself fading — his strength, his memory, his self — and there would be nothing he could do. The shade had woven itself into him. Removing it would kill him anyway.
So he walked toward the edge. Better to die on his own terms. Better to fall than to fade — to feel himself being consumed day by day, watching through dimming eyes as something else wore his face and spoke with his voice.
He stood at the cliff's edge. The wind tore at his robes. The clouds below were grey and endless.
He closed his eyes.
Lightning split the sky.
Not above him — He stumbled, turned, looked.
A crater. Fresh. Smoke still rising from the scorched earth at its center. And inside it — a baby.
Elder Han stared.
He had no family anymore. All alone in a sect that treated him as a convenient pair of hands — useful enough to keep, not talented enough to invest in. He'd spent his life on the periphery, watching other people have the things he never had. Students with masters. Families with homes. He'd made peace with it. Accepted that his life would be small and quiet and solitary and that when it ended, no one would notice.
He looked at the baby. The baby looked back at him — eyes wide, screaming, alone in the world.
He picked it up.
Not because he wanted a child. Not because he had a plan. Because the boy was alone, and Elder Han knew what alone felt like, and he couldn't walk away from it.
He named the boy Di Yusheng. Took him back to the sect. Raised him.
The first year was fine. The boy was healthy . Elder Han fed him, changed him, rocked him when he cried. It was clumsy work. He'd never cared for a child. But he did it because the boy needed him, and being needed was something Elder Han had never experienced before.
He told himself he would raise the child for a little more untill he was self sufficient then finish what he needed to.
The shade fed quietly. It had time. Its host was cooperative without knowing it — distracted, overworked, attributing every symptom to the demands of child-rearing. The shade drank. Grew. Settled in.
By the time Yusheng was old enough to walk and talk, Elder Han had changed. The warmth was still there — he cared for the boy, fed him, clothed him — but it was thinner. Like a fire burning low. He was quicker to silence. Slower to smile. The patience he'd had in the first year had eroded, replaced by a flat, mechanical efficiency. He did what needed to be done. Nothing more.
Yusheng noticed.
He was young, but he wasn't stupid. He could feel the difference — the way Elder Han's voice changed, the way his eyes drifted, the way he sometimes stood in a room for minutes at a time without moving, as if listening to something no one else could hear.
Yusheng assumed it was because of him. Because he was crippled.
They'd tested his meridians when he was a baby. All open — every single one, fully formed, no blockages. A body any cultivator would kill for. But the body wouldn't move freely. He was a perfect vessel with no way to use it.
A cripple.
Elder Han had been disappointed. He'd tried to hide it, but children see what adults try to hide. Yusheng saw. He saw the way Elder Han looked at him — not with anger, not with disgust, but with something worse. Resignation. The look of a man who had hoped for something and accepted that he wouldn't get it.
Yusheng told himself that was the reason. The change in Elder Han. The coldness. The distance. He was a cripple, and cripples were a burden, and burdens breed resentment.
He believed it for years.
Then he healed.
It happened overnight. During that day he truly thought elder Han would be happy for him but reality was cruel.
Elder Han looked at him and called him possessed.
No acknowledgment. No surprise. No joy. No relief. He looked at Yusheng with anger in fact. Yusheng first believed it was because of the situation he was found in but the doubt started when elder Han neither believed the peak master nor the sect master's words.
Which brought him to the conclusion elder Han wasn't searching for the truth about whether he was possessed he wanted the truth to be he was possessed but why?
It was obvious he wanted Yusheng to undergo exorcism. If he was exercised all that would be remaining is an empty vessel.
For a shade that has already fed once that would be a paradise. Of course that was only a hypothesis but it didn't matter anymore .
He had already decided if elder Han wasn't truly possessed it's a pity he didn't believe in him when it mattered but if he was then the shade won't torment elder Han anymore.
Di Yusheng never expected the chance to come so soon but he made sure not to waste it.
Yusheng would have killed an innocent man.
He accepted that. He'd accepted it before he drew the bow. The suspicion was strong enough. The evidence was strong enough. And the risk of being wrong was outweighed by the risk of being right and doing nothing.
Yusheng had decided which answer he expected.
He was ready to be wrong.
He wasn't.
The shade came out of Elder Han's head. Dark. Formless. Fighting. Lin Xue's sword came down and it was gone.
Yusheng stood in the shadow of the wall and watched the wisp dissolve into the evening air.
Relief.
It wasn't Elder Han. It was never Elder Han. The real Elder Han — the one who had picked him up out of a crater and carried him home — would have been happy when he wasn't a cripple anymore. Would have said something. Would have believed him.
The thing that had worn Elder Han's face for the last three years was dead. The body was on the ground, but it had been a corpse for a long time. Just a body that hadn't stopped breathing yet.
Yusheng looked away from the body.
He felt lighter. Not happy — he didn't think he'd feel happy about this. But lighter. The question that had been sitting in his chest — was answered.
And now Lin Xue was looking at them.
Luoxue was still processing. She'd told Yusheng to fire at Lin Xue. He'd fired at Elder Han instead. An outer elder was dead. A shade demon had crawled out of the body. A ten-year-old regressor had killed it with one strike and was now staring at the corner where they hid.
She looked at him. He was calm. Settled. He'd just killed a person who raised him and acted like it was no big deal. She felt a chill but now that she thought about it.
He'd known. Even Luoxue couldn't tell it was a shade untill it died.
She didn't say anything. There was nothing to say.
Luoxue touched Yusheng's arm.
"Time to go."
They moved.
