I Reincarnated as a Demon King,I Will Kill Everything

Smoke lingered. Silence—then a subtle electric hiss crept from the black crater I had just blasted.

ZRAK… ZRAK… ZRAK…

I turned sharply. The ozone stings my nose again. At the bottom of the crater, lightning fragments gathered like an angry beehive, weaving themselves into a lightning cocoon. The surrounding rocks melted, then floated, held in place by an electromagnetic field that had appeared out of nowhere.

Rena—still kneeling beside me—looked up, her breathing heavy.

"My Lord, he—"

"I know. Take three steps back. Recover your breath," I said flatly, without looking away.

The cocoon cracked.

CRACK! CRACK! CRACK!

Lightning exploded in all directions. Darrius emerged—no longer fully human. His skin was like bluish jade, his veins transformed into pulsating streaks of lightning. His eyes were two swirls of light, without pupils. In his chest—where he had thrust the spear—a lightning-wheel-shaped spear core spun, replacing his heart. The remains of the ancestral spear blade had fused together as a right arm bone, extending like an organic spear emitting wild ions.

Elrodan and Garruk, still at the edge of the field, froze for a moment.

"He truly has surpassed the threshold," Elrodan hissed.

Garruk gritted his teeth. "The final vessel."

Darrius raised his head. His voice was no longer human—part echo of thunder, part hiss of electricity.

"I have abandoned flesh and blood," he murmured. "All that remains is the sky spear."

I grinned faintly. "Interesting. Show me, Darrius—how many minutes you can buy with your life."

He raised his spear-arm. The horizon flashed. The air between us collapsed, the lines of space trembling.

[NAIBATA LONGGUR – FINAL VESSEL]

[HEAVEN-SUNDER LANCET]

Darrius vanished from sight—appearing right in front of me, faster than any lightning I'd seen. His spear-arm cut through the air, leaving a trail of ions that burned my skin. I raised Noa Genesis, parrying with an iron palm.

KRAAANG!

Our impact shattered the remains of the house into dust. Electricity coursed through my Overlord armor, trying to shock my soul from within. Noa grunted heavily from within the gauntlet.

"The current goes straight to the spiritual core. Careful, My Lord."

I twisted at the waist, countering with a right hook.

[DEMON HAND]

[BOOST]

The blow struck the side of his lightning helmet—Darrius's body was sent flying—but the ions condensed, regaining momentum, and he spun in the air, landing without losing speed. His spear sliced ​​through, two consecutive thrusts—one to the neck, one to the heart.

I hunched my shoulders, shifting a sharp half inch—letting the spear tip graze the armor without penetrating. Rainbow-black sparks erupted from Noa Genesis.

Darrius didn't stop. He merged with the lightning, transforming into a streak of light that bounced three times in the air—right, up, behind—before locking onto my position from a blind spot.

"Nice speed," I said quietly. "But I can still read it."

I kicked the ground.

[GRAVITY FIELD – POINT LOAD]

Gravity clamped down on his path—for a flash—just enough to create friction. The lightning faltered for a split second—an opening he wouldn't get again.

I swung straight.

[FOREFIST PUNCH] + [BOOST]

The fist struck—but the core in his chest spun, breaking the force, then deflecting my blow aside like a current swallowing a rock.

Darrius's eyes blazed. "You can't kill a spear. I'm not the target, I'm the trajectory."

In the distance, Elrodan loomed, the moon runes piling up again. Garruk raised his axe, lava dripping down in a torrent.

Time was running out. Darrius was burning away his remaining life. I could feel it—the false heartbeat in his chest was beating faster and faster. If left unchecked, he would blow up this entire plain along with his spear-heart.

I took a half step forward. The aura of darkness and moon rolled like a storm. Noa Genesis pulsed, the first jewel blazing.

"I've seen enough."

My wings spread.

"Darrius. Your finale. My finale too."

[ANNIHILATOR – BLACK MOON DRIVE]

Noa's roar resonated, heavy as a gong.

[BOOST ×2]

Darrius brought his spear down—ions screamed, the sky split.

ZRAK—!

We both vanished, then reappeared on the collision course. Darrius's celestial spear thrust straight; my fist—[ANNIHILATOR – BLACK MOON DRIVE]—hissed like a singularity being forced into birth.

[BOOST ×2]

Noa thundered in my gauntlet.

The impact extinguished the color. Sound vanished for a split second—then nature returned with a deafening bang. CRACK! His lightning ions shattered, the trajectory he called "eternal" crumbling under the weight of the black moon. I turned my shoulder, shifted the thrust line a finger, and struck his chest squarely at the spinning core.

CRACK!

The lightning wheel on his chest shattered; wild lightning erupted like a burning beehive.

Darrius froze. The light in his eyes flickered, his thunderous voice low.

"I… trajectory…" he whispered brokenly.

"Too much friction," I replied flatly.

I plunged Noa Genesis' palm into the center of his chest.

[SOUL CLAMP]

The gauntlet's pillars snapped shut like a dragon's jaws. With a single pull, the spear's core ripped from his lightning flesh, creaking like broken cosmic teeth. Darrius's body crumbled into charged fragments, then extinguished… like lightning that reached the earth too late.

Noah's heart throbbed with satisfaction; a single gem on his knuckle glowed electric blue, absorbing the remaining charge.

"Lightning charge integrated. Resistance increased. Piercing power: increased," Noah reported, his voice heavy.

I held my breath for a moment. "One done."

Garruk roared—his lava axe already hovering overhead.

[VOLCANIC CLEAVER]

The ground split open in a fiery red. Rena leaped across, her two dark swords clashing with the magma blade. CLANG! A blast of heat swept out, but Rena twisted at the waist and pressed from the blind side.

Elrodan behind her lit a moon sigil. Armless, he wove a spell with runes swirling around his body.

[MOONLIGHT VOLLEY]

Dozens of arrows of light emerged from the air, swooping toward Rena and me at once.

I raised my left hand.

[GRAVITY FIELD—WIDE]

The battlefield tilted to my will: heavy for Garruk and Elrodan, light for Rena. The moon arrows curved, Elrodan's line of fire arcing before sinking into the ground far from its target.

"Enemy calibration complete," Noa murmured. "Friendly mark marked."

"Take Elrodan," I said to Rena without turning. "Garruk is mine."

Rena nodded.

[CHAOS DOMAIN]

blossomed from her feet—a dark dome that muted holy effects for precious seconds. She broke through the rain of light, her two swords slicing through Elrodan's sigil like water.

I was already in front of Garruk. The giant axe fell—

I leaned back half an inch, letting the blade graze my Overlord helmet, then struck him in the solar plexus with a [FOREFIST PUNCH] pumped with [BOOST].

BOOOM!

Garruk took seven steps back, his wild eyes wide. He swung horizontally; I ducked, guided the axe past, and grabbed the handle near his palm—[GRAVITY PIN]—the weight instantly attached to the weapon. The next swing faltered, opening a gap in his ribs.

I threw a combination: liver–solar plexus–chin. The axe fell halfway, but Garruk, stubborn as a mountain, charged forward, his forehead like a steel anvil.

THOK!

My body was pushed away. He lunged, trying for a death hug.

"Close range? Wrong opponent."

I brought my palm to his chest. [BLACK MOON DRIVE – SHORT BURST].

DUUM!

Garruk's chest sank in, the lava on his axe blade suddenly extinguished by the energy vacuum. He staggered, coughing up hot blood.

On the other side of the field, Rena danced in the white rain. Elrodan summoned a pillar of light.

[ECLIPSE PILLAR]

The sacred pillar plunged down, nailing the ground.

Rena bounced off the shadow wall—[VOID PARALLEL]—her two swords crossing, cutting the pillar into shards that were immediately consumed by the darkness of the Chaos dome. She slipped to Elrodan's side, her blade sweeping across the runes surrounding the hero's body.

"Bring it down," Rena whispered.

CRACK!

A circle of runes shattered—the moon arrow dimmed.

Elrodan hissed, stacking new sigils through gritted teeth. "You think your darkness can swallow the moon? I named the light."

"I don't swallow," Rena replied flatly. "I extinguish."

She brought her elbow down on the base of Elrodan's neck—[HELL GATE—LOCK]—a brief stun, enough to close the distance again.

Garruk roared, forcing his axe up. "I—CLEAVE—YOU—!"

The axe descended; I crossed my arms—Noa Genesis shrieked, absorbing the force of the fall—then twisted at the waist and locked the axe handle with a brief [SOUL CLAMP]. The iron fibers roared—CRACK!—the handle cracked.

"Down."

I pushed his shoulder—[GRAVITY KNEEL]—his knee slammed into the ground.

His right fist swelled with the black moon.

"Sleep, Ironfist."

[DRAGON SHOT]—a compressed version—exploded point-blank into his face.

CRAK-BOOM!

Garruk bounced, hitting a boulder, sinking into it. He was still breathing—stubborn. Good. I wanted him to see what happened to his friend.

I turned quickly.

Rena was already behind Elrodan, the blade of darkness pressed against the back of his neck, the dome of Chaos still suppressing the light. The runes around him flickered, groping for their way out.

"Let him stand." I walked closer. Elrodan looked up, his moon-like eyes full of revenge—and something akin to desperation.

"Two choices." I held up two fingers. "Kneel or I'll make you follow Darrius."

The sky responded with a heavy silence. In the distance, Garruk's body crawled, Elrodan held his ragged breath, Rena waited for one word from me to cut.

Noa whispered from the gauntlet, calm and cold.

"Target lock. Orders, My Lord?"

I smiled faintly. "We end—starting with the archer without a bow."
