Dimensional Keeper: All My Skills Are at Level 100 Chapter 1287 Killing Demon Kings!

"Damn…" Max muttered, his voice filled with shock. The sheer durability of the demon king's physical form was far beyond what he had anticipated. However, he had no luxury to linger on that thought.

The third demon king launched an immediate assault. A volley of arrows, glowing with a sinister black light, materialized out of thin air and streaked toward Max in a rapid barrage. Their velocity was so extreme that they seemed to outrun time itself. Max swung his blade repeatedly, his movements clean and swift as he intercepted every projectile. Upon making contact with his sword, the arrows dissolved into a dark, swirling mist.

"Die!" a deep, guttural roar followed a heartbeat later.

The fourth demon king manifested right in front of Max. His arms became a blur, unleashing a tempest of motion. Within a single second, he threw over a hundred punches, each one saturated with lethal intent. This barrage of strikes originated from every conceivable angle, creating a terrifying illusion of countless fists closing in on Max at once.

Max met the ferocity with his own. His sword was infused with the fifth level concept of severing, the blade flashing incessantly as it parried every incoming blow. Sparks flew with every clash, and the entire dome shuddered under the weight of the resulting shockwaves.

Bang. Bang. Bang. Bang.

The rhythmic sound of metal meeting fist thundered through the sealed arena like a drum inside a stone chamber. Max sharpened his focus to a razor's edge, blocking every attack with flawless precision. Suddenly, a fierce red light erupted within his eyes.

The Storm King’s inheritance surged once more, its power expanding with violent force. Heaven’s Wraith was triggered, and crimson lightning snaked around Max’s limbs like wild, electric serpents. His aura reached a new peak as he channeled every drop of that energy into his blade.

He swung.

Sky Shattering Sword Art — Heaven Defying Sword.

This technique merged the absolute power of the fifth level severing concept with the crushing strength of the Storm King’s lightning inheritance. A brilliant arc of pure destruction fell upon the fourth demon king. Having just finished his barrage, the demon barely had a moment to breathe before the counter-strike arrived.

The blade moved with such blinding speed that the demon king couldn't even raise his arms to defend himself.

In one clean, fluid motion, the sword sliced through his torso.

A heavy silence gripped the air as the demon king’s massive frame split down the center. The two halves hung in the air for a fraction of a second before crashing into the ruined earth with a dull, lifeless thud. The severing concept had not merely destroyed his flesh; it had sliced through his very essence, making any hope of regeneration impossible.

Max stood tall, wreathed in crackling lightning, his sword vibrating with leftover energy. One demon king was already dead.

"How dare you kill my brother?" the first demon king bellowed. His voice carried a depth of rage that caused the spatial dome itself to tremble. His fury distorted the air, and the ground cracked beneath his feet as he lunged forward, throwing a punch that was significantly heavier and more powerful than his previous efforts.

His aura exploded violently, saturating the dome with the suffocating pressure of the fifth level concept of strength. With eyes burning with murderous bloodlust, every muscle in his giant body pulsed with destructive intent as he charged directly at Max.

Max watched the approach with cold indifference. As the enraged demon king reached him, Max slowly returned his sword to its sheath and raised his right hand. A calm, mocking smile played on his lips. He tightened his fist and called upon the power of the first divine vein of the Seven Divine Veins: the Vein of Origin.

As that power woke up, an ethereal sensation washed over him. It felt similar to the rush of his Draconic Essences, yet it was fundamentally different—purer, deeper, and far more ancient. The Vein of Origin throbbed within his body, charging his fist with a force that went beyond the limits of mere biology.

A grin widened on Max’s face as he felt the energy crest. "Come then," he whispered, his voice tinged with growing excitement as the power peaked. "Take this." Without a moment's hesitation, Max drove his fist forward, meeting the descending blow of the furious demon king head-on.

Bang.

The impact unleashed a violent shockwave that rippled through the entire dome. The outcome was decided the instant their knuckles met. Max’s punch held such irresistible force that the first demon king’s fist was instantly vaporized into a spray of blood and bone fragments.

The demon king’s arm twisted into a gruesome shape from the force, and his entire body was launched backward at a terrifying speed, flying away even faster than he had originally charged.

Max didn't let the chance slip by. Red lightning flared around him as he tapped into the Storm King’s inheritance again. His form blurred and vanished, only to reappear instantly in front of the demon king, who was still tumbling through the air from the previous punch.

The demon king’s eyes bulged in terror as Max appeared before him, appearing perfectly composed despite the chaos of the fight.

Max gripped his sword with both hands, focusing every bit of his available power into a final strike. This wasn't the wide-range, explosive blast he had used before. This was a concentrated, refined, and deadly blow—the absolute peak of the Sky Shattering Sword Art.

Sky Shattering Sword Art — One Sword: All Conquered.

The blade swept down in a single, elegant motion. There was no thunderous roar or blinding flash of light. Instead, it carved through the atmosphere with a terrifying silence, so sharp that space itself seemed to bend around the edge. The simplicity of the move masked a level of lethality that eclipsed every other attack Max had used during the battle.

Slash.

The first demon king’s massive body didn't just split in two; it disintegrated into a thousand fragments. The severing concept worked in perfect unison with the divine vein and the storm inheritance, creating a cut so absolute that it severed the demon king's very soul. His body vanished in mid-air, turning into dust that faded away before it could even hit the ground.

The entire exchange had taken only a few seconds.

Another demon king was gone. Max stood there completely unscathed, his sword shimmering with an aura so potent that the remaining demon kings felt a cold shiver deep within their ancient souls.
