It happened at lightning speed that even Long Shenyu curled his brows.
The energy he had sensed beneath the surface erupted.
It came through the earth like tendrils — thick ropes of alien Qi that burst from the soil in explosive geysers of dirt and stone, each one targeting a fleeing Sky Lord heir with a precision that could not be accidental.
Luo Cangxuan saw it coming. His sword flashed — Nine Severing Qi condensing into a desperate horizontal slash that cut through the first tendril. Two more burst from the ground behind him. He twisted, parried, severed one. The third wrapped around his ankle and yanked him downward with a force that cratered the earth around him.
He managed to activate a signal talisman. A burst of coded Qi erupted skyward from his hand — a distress beacon, the kind that would carry across domains and alert his sect's nearest watchtower that an heir was dying.
Su Ran, Wei Jinhai, and Zhong Tielan did the same. Three more signal talismans blazed to life, each launching their emergency frequencies into the sky. Four pillars of light — red, white, black, and crimson — streaked upward and vanished into the clouds.
Then the tendrils killed them.
It was not slow. The strange energy wrapped around the four injured Sky Lord heirs with the methodical efficiency of a predator that had cornered its prey and saw no reason to prolong the engagement. Qi was drained. Cultivation bases were consumed. The light left their eyes as the energy streams were recalled from their corpses. Four heirs of upper Noble Domain powers corpses littered across the ground.
Silence returned.
Long Shenyu stood in the centre of the carnage and looked at the disturbed earth where four people had been alive seconds ago.
His Dragon Soul sensed the energy going back underground in an arranged pattern.
He grew even more curious.
Mei Qingxue stood beside him, her face pale, her silver-bright eyes wide.
Shen Lanyue stood on his other side, her composure intact but strained.
Ning Huang remained in the centre of the crater field, her spear still in her hand, her Aurora Judgment Lightning flickering along its length in diminishing arcs. She was staring at the disturbed earth with the sharp, evaluative focus of a woman who understood that what had just happened changed everything she thought she knew about this location.
And from the ridge above, looking down at all of them with an expression of pure, unbridled contempt, Long Shenyin laughed.
The sound was disdainful. Cold. Aimed directly at Ning Huang with the precision of a thrown blade.
"So this," she said, voice carrying cleanly over the ruined ground, "is the famous war-heiress?"
Her lip curled.
"Six people pressed you, and you still needed the field itself to finish the job." Her gaze drifted once over the corpses, over the blood, over the smoking craters. Then it returned to Ning Huang's face. "Weak."
No one moved.
Long Shenyu, standing a short distance behind them, simply sighed.
Ning Huang lifted her head.
There was no visible flinch. No outward sign that the insult had landed.
But the temperature in the air around her changed.
Long Shenyin noticed it and, naturally, kept going.
"You do have barely passable lightning," she said. "I'll give you that. Clean enough. Sharp enough. Better than the usual self-important trash that comes out of thunder sects."
She tilted her head a fraction.
"But barely passable means nothing. If I were in your place, corpses would have hit the ground long before my spear arm got tired."
There was no posturing in Long Shenyin's voice. No effort to provoke for the sake of amusement alone. She meant every word. In her eyes, Ning Huang had not fought brilliantly against impossible odds. She had merely taken too long.
Ning Huang's grip tightened around her spear.
The sound was small. Barely audible. Leather pulling tight against polished wood.
When she spoke, her voice was low and cold enough to cut.
"You killed a distracted man from a blind angle," she said, "and now you bark from a ridge like a stray beast. Do you mistake that for skill?"
Mei Qingxue drew a breath and held it.
Shen Lanyue's eyes flicked to Long Shenyu, already measuring whether he would intervene.
Long Shenyin smiled.
It was a bad smile. The kind that never promised mercy.
"Then come show me yours."
The world narrowed.
Ning Huang's heartbeat changed.
To ordinary ears, it was nothing. To cultivators with real perception, it was the first drumbeat of a storm front gathering behind mountain clouds.
The Thunder Empress Heart-Vein answered her anger.
Thump.
Heaven and earth energy in the surrounding field quivered.
Thump.
Aurora Judgment Lightning flared brighter, pouring from her like imperial law made visible. It was no longer the measured lightning she had used while conserving strength against six opponents. This was something else. Pride given force. Fury given structure. Humiliation fed into discipline until it sharpened rather than scattered.
Her body did not tense.
It aligned.
The Heaven-Coronation Lightning Canon circulated through her meridians with the smooth, merciless precision of a palace execution order. Judgment-light coiled down the length of her spear. Layer after layer of radiance condensed around the blade-tip until the weapon looked less like steel and more like a decree from heaven compressed into a killing line.
And at that moment, Ning Huang vanished.
Radiant Step Through Empty Skies left only a white-gold streak over the broken field, so fast that the torn ground below split open again from the pressure of her passage.
To Mei Qingxue and Shen Lanyue, it looked like judgment itself had chosen a direction and moved.
To Long Shenyu and Long Shenyin, it was fast—
but not fast enough.
She appeared at the base of the ridge in the same breath.
Her spear thrust forward.
It was a beautiful attack.
That was the first thing even Long Shenyu admitted.
Nine layers of lightning spiraled over one another around the spearhead, each layer thinner, denser, more refined than the last. The outer arcs were bright and imperial, full of the suppressive authority Heaven's Edict Thunder Palace was feared for. The inner arcs were quieter and deadlier, so condensed they hummed instead of crackled, carrying the execution-intent of Aurora Judgment Lightning straight toward the body's most important points.
The slope below the ridge split apart.
Stones burst into powder.
The charged air whined around the spear like a blade being drawn through the throat of the world.
Ning Huang's eyes burned.
"Kneel!"
Long Shenyin did not move away.
A sane fighter would have dodged. A cautious fighter would have shifted footing, broken the angle, tested the line, given ground before retaking it.
Long Shenyin did none of that.
She stepped into it.
One step.
One hand rose.
Only one.
Black Qi rushed over her fingers in a thin, dense layer so compressed it did not spread outward. It darkened the very air around her hand. Crimson-black lightning crawled beneath her skin like veins of living destruction. Her Primordial Asura Dragon Blood answered Ning Huang's imperial fury with something older and crueler—battle instinct stripped of all ornament, slaughter intent honed until it was cleaner than art.
Then she attacked.
There was no grand technique name.
No wide wave of force.
Just a short, brutal diagonal cut of her hand through the air.
It was horrifying precisely because it looked simple.
Her hand descended, and the world split with it.
Ning Huang's layered spear-line met that black-red edge and came apart at once. The first layer of verdict lightning ripped open. The second shattered. The third through seventh collapsed in a chain reaction as if the attack had found the exact weak seam running through all nine layers and driven a knife into it. The spear's forward authority died mid-thrust. Its coherence broke. The imperial decree turned back into lightning.
Too late.
A crescent of destruction, born from Long Shenyin's hand, punched through the broken line and slashed across Ning Huang's upper body.
Blood burst into the air.
Ning Huang was thrown backward hard enough to tear trenches through the slope. Her shoulder split open. The line ran across collarbone and side, ripping cloth, skin, and Qi-armor alike. Her fingers nearly lost the spear. She hit the earth, skidded, and would have gone down entirely if she had not rammed the butt of her weapon into the ground and forced herself to stop by sheer will.
Silence hit the field like another impact.
Even Ning Huang froze for a heartbeat.
She had attacked with all of her anger, all of her discipline, all of the murderous pride Heaven's Edict had hammered into her since childhood.
Long Shenyin had answered with one hand.
One movement.
Nothing more.
Ning Huang lifted her head slowly.
Shock was there.
Only for an instant, but it was there.
Long Shenyin stepped off the ridge.
She did not jump. She descended.
The motion was light, almost graceful, but there was something blade-like in it anyway, as if the air parted for her because it feared being cut if it resisted. She landed on the broken slope and walked forward through the settling dust with blood-dark lightning crawling lazily over one arm.
Her eyes were brighter now.
Interested.
"Much weaker than your mouth," she said. Her voice was mild. That made it worse. "But your expression did improve."
Ning Huang's teeth clenched.
She rose.
Not easily. Not cleanly. But she rose.
Blood darkened half her upper robe. The wound was serious. A normal Sky Lord would already be calculating retreat, suppression, recovery. Ning Huang planted the spear beside her, forced her spine straight, and stared at Long Shenyin as though pain were an insult she would deal with later.
"Again," she said.
Long Shenyin's gaze sharpened.
Until then, despite everything, there was some brutal interest. Curiosity. The contempt of someone deciding whether an opponent deserved a second strike.
But the next move in her eyes was not a lesson.
It was death.
Black-red destruction lightning wound around her arm in a tightening spiral. It did not flare brightly. It condensed. The pressure of it was ugly, intimate, and vicious, the kind of force meant to go through flesh, meridians, dantian, all the things that mattered, and leave a body alive just long enough to understand what had been taken.
Mei Qingxue went pale. "She's really going to kill her—"
"She was always going to," Long Shenyu said.
And then he moved.
No one saw the start.
One moment Long Shenyin was lifting her hand to end Ning Huang where she stood. The next, Long Shenyu was between them.
The timing of it was obscene.
He entered at the exact convergence point of Long Shenyin's strike, where all that condensed slaughter-force came together into one killing line. Two fingers rose. Calmly. Casually, almost. He caught the core of the descending attack at the instant it became most dangerous.
The collision detonated outward.
Cracks raced through the ground beneath his feet in a spiderweb pattern. Stone fragments jumped into the air. Wind blasted out in a ring and threw dust in every direction. Mei Qingxue had to shield her eyes. Shen Lanyue's robes snapped around her legs.
Long Shenyu's robe fluttered once.
That was all.
He did not sink into the ground. Did not give an inch. His expression did not change.
Long Shenyin stared at him.
"Move."
Long Shenyu ignored her first.
He turned his head and looked at Ning Huang.
She was still standing. Barely.
Blood at her collar. Blood at her side. Blood on the fingers wrapped around her spear. Her breathing had lost its earlier smoothness. Her pride had not. If anything, being overwhelmed had only set it burning harder. She hated the wound. She hated being outclassed. She hated even more that someone had stepped in before the outcome finished itself.
Long Shenyu looked at her and smiled.
Not mockingly.
That was what caught her off guard.
There was amusement in him, yes. Shamelessness too. But not ridicule. Not pity. Just a maddening, easy calm, as though the violence around him were only one part of what he was paying attention to.
"I saw her first," he said. "I like her. I can't let you kill her."
That hit harder than the strike had.
Ning Huang stared at him.
For the first time since the battlefield came into view, true confusion crossed her face.
He had shattered the common sense of combat once already. A mere Origin Core cultivator had torn a Sky Lord apart as if realm difference were a rumor. That alone was enough to crush a disciplined mind. But now, after stepping between two killing blows, when any reasonable man would have offered some grand justification—alliances, strategy, sect politics, hidden calculations—
he said that.
Plainly.
As if it were the most natural explanation in the world.
Heat touched Ning Huang's face before she could stop it.
She felt it immediately and hated it with a purity rarely reserved for enemies.
Mei Qingxue pressed her lips together, and despite the tension still gripping the field, the smallest helpless smile appeared at one corner of her mouth. Shen Lanyue let out a very quiet breath through her nose and looked away on instinct, like someone who had seen this exact brand of nonsense before and resented being unsurprised by it. Still, when her eyes slid back to Ning Huang and caught the flush under all that blood and fury, something in her gaze sharpened.
Ning Huang recovered by attacking the only target available.
"Who asked for your protection?"
Long Shenyu's smile widened slightly.
"You didn't."
Then he added, with unbearable ease, "I decided."
That somehow made it worse.
Before Ning Huang could answer, Long Shenyin gave a disgusted click of the tongue.
"You're still doing this?" she said. "Even after everything? Still dragging women into your path like tools and calling it cultivation?"
Long Shenyu finally turned.
His smile remained.
But it changed.
It did not disappear. It simply lost warmth and gained edge.
"You still think you understand my methods because you saw the old version of them." His eyes moved over her once, calm and insulting in equal measure. "That alone tells me how far behind you are."
Long Shenyin's expression hardened.
The air around her grew sharp enough to sting.
Long Shenyu kept speaking. No one in either life had ever been better at finding the precise point where his sister's patience ended, and her temper began.
"My path changed." He shrugged. "Yours didn't. You found one answer when you were younger and worshiped it hard enough to mistake stubbornness for depth."
A pulse of black-red lightning snapped from Long Shenyin's sleeve and blew a groove into the ground.
He went on anyway.
"Hit harder. Then harder again. If that fails, use more killing intent and glare like it's philosophy." He looked almost bored. "Loud. Direct. Predictable."
That did it.
Long Shenyin attacked without another word.
No taunt. No warning. No wasted motion.
Her strike drove straight for his centerline, angled with the exact malice required to cripple cultivation even if the target survived. Black destruction lightning screamed around her arm. The force behind it was so vicious that even Ning Huang, wounded and furious as she was, felt the chill of it in her bones.
This was not sibling bickering.
This was lethal.
