Dimensional Keeper: All My Skills Are at Level 100

"Die!" The furious roar of the four demon kings shook the entire spatial dome as they launched their assault simultaneously.

The death of Balthazar, who had been their most promising disciple and the one they had groomed to surpass even themselves, ignited a rage so intense that the atmosphere warped around them.

Their killing intent surged like a tidal wave, and their bodies moved with frightening coordination. The grief of losing Balthazar mixed with their hatred for Max, creating a murderous aura that made the entire space vibrate.

The first demon king reacted faster than the others. He pressed his feet into the cracked ground, and the impact sounded like thunder. The ground beneath him caved in, forming a deep crater as he propelled himself forward like a compressed spring being released. His massive body shot through the air with explosive force, and the earth shattered behind him.

In the next instant, he appeared before Max, and as he arrived, his power erupted outward. The fifth level concept of strength radiated from his body in violent waves. Every muscle in his form swelled with destructive energy as he drew back his arm and delivered a fist strike capable of pulverizing mountains into sand.

Max reacted instantly. He shifted the sword in his right hand to his left hand with a swift motion. His right fist clenched tightly as he gathered all the Draconic Essence within his body and focused it into that single strike.

His scales glowed beneath his skin for a brief moment as pure draconic might surged through his arm. When the demon king's fist descended upon him, Max punched forward with everything he had, meeting force with force.

Bang.

The impact was colossal. The ground beneath them collapsed entirely, forming a crater that grew larger with every moment the two forces clashed. Shockwaves rippled outward, shaking the entire spatial cage.

Dust and debris exploded upwards like a volcanic eruption. The destructive force that radiated from their clash pulverized everything in its vicinity. A heartbeat later, one figure was flung across the dome with immense speed, carving a long trail of destruction through the air.

It was Max.

He shot backward like a cannonball, and the only thing that stopped him from being smashed into the barrier was his quick instinct. He stabbed his sword downward into the ground with his left hand, using it as an anchor to slow his momentum.

The blade screeched along the fractured earth, sparks flying everywhere as Max finally came to a stop. He stood still, breathing heavily, his fist slightly trembling from the raw force he had just endured.

"What immense strength…" Max muttered, shock filling his eyes. He had expected the demon kings to be strong, but not this strong. The first demon king's fist had nearly shattered his arm. The brutal force behind that strike was far beyond anything the peak Divine Rank demons he fought earlier could generate. This was a different level entirely.

But as he took a breath and thought more deeply, he understood. These demon kings were not true residents of the mortal realm. They were beings from the Divine Realm, entities who had lived long enough to comprehend higher laws. In the mortal realm, where the ceiling of power restricted them, the highest they could manifest was the fifth level concept. For them to have reached it was not surprising. It was, in fact, expected.

Max tightened his grip on his sword. The realization brought clarity rather than fear. He had already accepted that this battle would not be simple. These were beings who had clashed with divine beasts and survived. The fact that their full power was restricted did not make them any less dangerous.

And yet, Max did not step back. His eyes sharpened as the other three demon kings closed in with killing intent boiling in their veins.

Max steadied his breathing as the four demon kings regrouped, each preparing to launch a coordinated attack. His Three Dimensional Body scanned their movements with ease, capturing every shift of muscle, aura fluctuation, and intent. It was as though time slowed around him, allowing his senses to dissect the battlefield with perfect clarity.

His eyes swept across the four demons, noting the distinct concepts that radiated from each one.

The first demon king surged with the fifth level concept of strength, his body crackling with raw destructive force. The second demon king radiated a similar intensity, but his aura pulsed rapidly and unpredictably, marking him as the wielder of the fifth level concept of speed.

The third demon king emitted a deep, devouring darkness, revealing mastery over the fifth level concept of darkness. The fourth demon king, however, released a strange, abnormal aura. Max could not immediately identify it, and that uncertainty made the fourth the most dangerous.

Rather than risk being caught off guard, Max chose to target the second demon king first, the one with the concept of speed. Eliminating him would reduce the unpredictability of the battlefield significantly.

"Die!" all four demon kings roared together. Their combined killing intent surged, filling the spatial dome with pressure so heavy that the air itself seemed to shrink. Their bodies blurred into motion as they converged upon Max with deadly precision.

Despite their speed, Max remained perfectly calm. The fury of four ancient demon kings crashing toward him did not shake his composure. He merely exhaled and summoned the power of the Storm King's inheritance.

A sudden burst of red lightning flickered around his body, wrapping him in a storm of crackling energy. The aura of Extreme Speed surged through him, bending space slightly around his form. Then his figure vanished from the demon kings' sight. He was no longer standing where he had been a heartbeat ago.

He reappeared directly in front of the second demon king, sword raised high, its blade glowing with thunderous intensity. With a single motion, Max unleashed the Heaven Piercing Thunderclap Sword.

Bang.

The impact sent the second demon king flying backward like a missile. His massive form tore through the ground, skidding across shattered stone until he crashed into a distant wall of the spatial dome.

But even after such a powerful strike, the demon king rose. Max stared in disbelief as he saw only a shallow gash across the demon king's chest. The sword technique combined with Extreme Speed should have carved through almost anything, yet here it barely broke the skin.
