The air didn't just turn cold; it curdled.
The tribal scavengers, the Ghost-Pale Bone Eaters—froze mid-lunge. Their jagged stone knives hissed against a translucent shimmer of jade light that had surged from Lei Ze's chest. The Jade Sun Pagoda, buried deep in his spiritual marrow, wasn't letting them through.
One of the creatures hissed, a sound like dry husks rubbing together. "Can't... touch."
"Take him," another rasped, his eyes fixed on Lei Ze's throat. "Kill him later. Feast."
Ying Hua's eyes flickered open. The world was a smear of gray and orange. Her head throbbed with the rhythm of a war drum, every pulse sent a spike of nausea through her gut. She remembered the throne room, the violet smoke, and the sickening crack of the Jie Clan's arrival. After that, nothing.
She squinted. Lei Ze was sitting there, a statue in the center of a circle of monsters.
She tried to stand. Her knees buckled once, twice, before she caught her weight against a damp trunk. Her palm began to hum, a faint emerald Qi bleeding through her skin.
"Hey!"
The Bone Eaters spun. Their joints popped and groaned with every movement, like old floorboards.
"Who is this one?" the leader stepped forward, his four arms twitching. "Beautiful... supper."
Ying Hua didn't like the way he said supper. She straightened her back, pulling what was left of her sect's authority around her like a tattered cloak.
"Leave him," she said. Her voice was thin but sharp. "Go back to the dirt you crawled out of."
The creatures shared a look, a chorus of clicking teeth. They didn't bother responding. The leader gestured with a bone staff, and three of them scrambled up the trees, vanishing into the canopy with unnatural speed.
Ying Hua took a breath. It tasted like ash. She didn't wait.
She vanished.
A soft gasp rippled through the clearing. Then, a wet, heavy crunch. One of the Bone Eaters plummeted from the branches, its skull hitting a rock with enough force to spray the moss crimson. The head didn't just break; it folded inward.
The others shrieked, jumping back toward their leader.
"Who is she?"
They didn't get an answer. A translucent blade, forged from pure Qi, tore through the throat of a second scavenger. Ying Hua reappeared for a split second, pulling the blade free before shoving it through the creature's back. Its heart hit the dirt with a dull thud.
The remaining two broke. They scrambled over each other, frantic to reach the treeline.
Ying Hua was faster. She moved through the shadows of the high branches, a predator in silk. She dropped onto the next one, driving her blade through the top of its head and down into the gullet.
The leader's legs gave out. He collapsed, his heart pounding so hard his chest rattled. He couldn't see her, but he could hear the soft, deliberate crunch of leaves getting closer.
"Please," he wheezed. "Spare... life."
The invisible blade hovered inches from his eyes. Ying Hua stood over him, her hand raised to finish the stroke.
Then, a bolt of red lightning, oily and violent shattered the air. It struck the Qi blade, snapping it like glass. Ying Hua stumbled back, a thin line of blood blooming on her hand where the feedback had bitten into her.
She became visible, her chest heaving.
Lei Ze walked toward them.
The aura rolling off him was wrong. It was a suffocating mix of black and crimson, a heavy, demonic pressure that made the forest feel small. Ying Hua's breath caught.
She remembered him, the boy from the frozen river but the person standing there now was a stranger.
"A demon," she whispered, backing away until her spine hit a tree.
Lei Ze exhaled, a plume of dark mist. He looked down at his hands. The Three Cores were stabilizing, but the dark core was winning. It was louder than the others.
He stepped past her. The sheer weight of his Qi made her skin prickle.
"I'm not a demon," he said. It was a soft whisper, almost a secret.
He knelt in front of the shivering scavenger.
"Where is it?" Lei Ze asked. "The City of Iron Shadows? Where do the Dark Lords gather?"
The creature didn't hesitate. It pointed a trembling finger toward the east, toward the jagged, lightless horizon of the Wanyong Province.
Lei Ze stood, folding his hands behind his back. The dark aura didn't fade; it just settled.
"Go," he ordered.
Ying Hua found her voice. "What? They tried to kill you!"
Lei Ze turned. His eyes were cold, but there was a flicker of something human behind the gold-and-black swirl. Ying Hua felt a heat creep into her cheeks that had nothing to do with the fire. She tucked a loose strand of hair behind her ear, her gaze dropping.
"I said go," Lei Ze repeated.
The creature scrambled away, but it didn't get far.
A mass of light purple and oily black smoke dropped from the sky like a falling mountain.
The scavenger was jerked upward, hanging in mid-air as if an invisible rope had found its neck. It kicked twice, a frantic, useless dance, before its body went limp.
It hit the ground with a sickening squelch.
Ying Hua stepped closer to Lei Ze, her hands tight. "What is that?"
Lei Ze didn't move. He stared at the settling smoke, his face hardening into a mask of stone.
"The Black-Bone King," he said.
The name felt like a curse in the cold air.
The cold didn't just bite; it settled into the marrow. Lei Ze let out a long, slow breath, the mist from his lungs curling toward the slumped body of the scavenger. He stepped back, his shoulder brushing against Ying Hua's. The contact was brief, a sudden heat through the layers of silk, but he felt her tense.
"Stay close," Lei Ze said. His voice was a dry rasp, barely audible over the wind. "He's dangerous."
He adjusted his stance, moving an inch away. The space between them felt heavier than the contact had. Ying Hua stared at the spot where his arm had been, her fingers curling into her palms. She looked like she wanted to say something, or perhaps strike him, but she settled for a rigid, prideful silence.
She took a step forward, her chin lifted, heading straight for the swirling purple haze.
Lei Ze's hand shot out. He caught her wrist, the grip tight and unyielding, and yanked her back until she hit his chest.
"What do you think you're doing?" he hissed near her ear. The weight of his internal cores was a physical pressure now, making his teeth ache. "You want to die?"
Ying Hua wrenched her arm free. She didn't look at him, but the flush on her neck wasn't from the cold. She crossed her arms, staring down the clearing at the shape forming in the smoke.
The Black-Bone King didn't walk so much as he glided, the purple mist acting as a shroud. He stopped. His head tilted at a sharp, unnatural angle, his gaze fixing on Lei Ze.
Lei Ze didn't move. He stood with his hands at his sides, his face a mask of blank, stubborn innocence. It was a lie, and they both knew it.
The distance was twenty paces. Then, it was zero.
The King moved with the smoke. One moment he was a silhouette; the next, he was a freezing weight behind Lei Ze's shoulder. Long, obsidian-sharp nails pressed into the fabric of Lei Ze's robe, catching on the skin.
Lei Ze turned his head slowly. He was looking into eyes that held a thousand years of slaughter and a very specific kind of loneliness. The kind that came from being the last. From being the boy who watched the Shèng Tiān Fǔ Sect—the sun-sovereigns of the six continents burn his heritage into ash while he hid in the soot.
"What do you want, King?" Lei Ze asked.
The figure hesitated. The title hit him like a physical blow. No one called a demon a King anymore; they called them vermin.
Suddenly, the air in the clearing buckled.
Inside Lei Ze's spiritual sea, the black tide of Kūn Zhān's energy went feral. It lunged at the golden anchors of the Pagoda, thrashing with a sudden, violent recognition. The pressure was too much. Lei Ze's knees hit the dirt with a wet thud. He coughed, a spray of dark, iron-tasting blood hitting the moss.
"What did you do to him?" Ying Hua was there, her hands on his shoulders, her face twisted in a snarl directed at the demon.
The Black-Bone King didn't answer. He was staring at the aura bleeding out of Lei Ze's pores. It was a jagged, red-black Qi, pulsing with the cadence of a heart that should have been dead for an eternity.
The King's hand trembled. The nails retracted.
"Dad?" the demon whispered. The voice was hollow, breaking like dry glass. Tears welling in eyes that hadn't felt moisture since the massacre. "Is that... you?"
Lei Ze forced his head up. His vision was swimming in red, the demonic core in his chest roaring so loud he could barely hear his own thoughts. He looked at the creature, the terrifying prince of smoke and saw the terrified child underneath.
"Lord Kūn Zhān's son?" Lei Ze wheezed.
The connection was a live wire between them. The heir of the smoke demons and the vessel of the Demon King's fragment.
