Cosmic Ruler - Chapter 521

Chapter 521: Nihlus
Nihlus, The Challenger

For the first time, Aiden felt the pressure.

Nihlus was more than a rival now.

He was matching him.

Step for step.

Strike for strike.

And not just because he was adapting—

But because he was creating.

Aiden barely dodged as Nihlus’s sword shifted mid-swing, expanding and fracturing into a thousand voidfire shards that launched in every direction.

Aiden twisted his body, golden energy exploding outward.

“Primal Shift!”

His power compressed and detonated, vaporizing the incoming projectiles—

But Nihlus was already behind him.

“Void Requiem.”

A blade of pure severance slashed down.

Aiden had only an instant to react.

He raised his arm, golden energy flaring—

—𝘊𝘙𝘈𝘊𝘒—!

The force sent him crashing into the ground below, carving a massive crater into the land.

For the first time in this battle—

Aiden was the one sent flying.

The Thrill of the Challenge

Aiden lay there for a moment, feeling the impact echo through his body.

And then—

He laughed.

Loud. Wild. Unrestrained.

“Now THAT’S what I’m talking about!”

He stood, flames roaring around him, his golden energy burning hotter than ever.

“I was starting to think I’d never have a real fight again.”

Nihlus descended from above, his voidfire pulsing with power.

“You will not be disappointed.”

Aiden grinned.

His eyes burned.

His aura flared.

This wasn’t just another battle anymore.

This was a fight that would define the future.

A duel between the first two beings of this new world.

And neither intended to lose.

They charged at each other once more—

And the battle truly began.

The battlefield warped as Aiden and Nihlus clashed once more, their strikes carrying such force that the laws of this reality bent to accommodate them.

The ground beneath them no longer existed as mere terrain—

It was shaped by their presence, their will.

Mountains rose and fell with every impact.

Suns ignited and collapsed in the distance, formed from stray embers of Aiden’s golden flames.

The void itself shuddered, pulsing in rhythm with Nihlus’s abyssal energy.

This was no longer a simple battle.

This was the forging of a legend.

And neither side was backing down.

A Clash Beyond Limits

Aiden dodged a voidfire slash, twisting midair as golden flames coiled around his arm.

“Solar Rupture!”

He threw a punch so powerful that space itself shattered outward, sending shockwaves across the horizon.

Nihlus vanished in an instant, his presence flickering out of existence—only to reappear behind Aiden.

“Singularity Rend.”

His blade swung downward, severing the very concept of distance, erasing the space between them.

Aiden barely had time to react.

Instead of dodging—

He countered with force.

—𝘊𝘙𝘈𝘊𝘒—!

Their attacks collided, causing an explosion so vast that the sky split apart, revealing the empty nothingness beyond.

For a brief moment—there was nothing but silence.

Then—

The world reassembled itself, adapting to the scale of their battle.

And both warriors stood, unscathed, grinning.

The Birth of True Combat

Aiden wiped a bit of dust from his shoulder, his golden aura flaring back to full strength.

“Not bad. You’ve got some real force behind that blade now.”

Nihlus, for the first time, let out a small chuckle.

“You are the one who forced me to evolve.”

“And I am not finished yet.”

Aiden’s eyes narrowed in excitement.

“Then keep going. Show me what happens when you stop following and start leading.”

Nihlus Breaks Through

Something shifted.

Nihlus’s void energy, once a swirling, chaotic force, suddenly stabilized.

It was no longer just destruction.

No longer just adaptation.

It had become absolute.

For the first time, Aiden felt it.

A power that wasn’t trying to match his own—

A power that wasn’t learning from him—

But a power that was truly independent.

Nihlus raised his blade.

And the moment he did—

Everything around them ceased to move.

The stars froze in place.

The winds vanished.

The ground stopped trembling.

For a split second—there was no reality.

Only Nihlus.

“Oblivion’s Dominion.”

The void expanded, no longer an abyss—

But a realm of his own making.

Aiden exhaled.

He’s not just fighting anymore.

He’s creating his own laws.

A grin spread across Aiden’s face.

“Now we’re talking.”

A Duel That Will Shape the Future

For the first time—

Two beings in this reality had created something unique.

Aiden’s golden flames—pure, untamed creation.

Nihlus’s void—absolute dominion over the unknown.

This battle was no longer just about strength.

It was about who would define the world itself.

And neither would back down.

They charged one last time—

And the world trembled under the weight of their clash.

The entire realm trembled, the battle between Aiden and Nihlus reaching a level beyond anything ever witnessed.

This wasn’t just a test of strength.

This was a battle between two forces that had stepped beyond limits.

Aiden, the Architect of this world, the one who carved creation into existence.

Nihlus, the Firstborn turned Challenger, the one who sought to forge his own dominion.

Their strikes no longer just shook the world.

They shaped it.

Reality Itself Fights to Keep Up

Aiden’s golden flames blazed, burning brighter than ever.

“Celestial Inferno!”

He launched forward, his fists striking with enough force to collapse entire star systems.

But Nihlus stood unshaken.

His void energy stabilized further, his aura pulsing like a heartbeat.

“Oblivion’s Requiem.”

His blade swung once.

And in that instant—

Everything vanished.

Not just space.

Not just matter.

But the very concept of resistance.

Aiden felt it—

The sensation of a force that didn’t just erase, but remade everything it touched.

For the first time, he realized—

Nihlus was no longer following him.

He was creating something of his own.

This isn’t just destruction.

This isn’t just creation.

This is something entirely new.

Aiden grinned.

“That’s what I like to see!”

Breaking Past The Final Barrier

They moved again.

Faster.

Beyond light.

Beyond space.

Beyond even time itself.

Every strike reset the battlefield.

Every counter reshaped the skies.

There was no more hesitation.

No more learning.

This was pure combat.

The Moment of Decision

For the briefest second—everything stopped.

Aiden and Nihlus stood across from one another, their bodies burning with power, their gazes locked.

Both understood.

This next attack would decide it.

Not who was stronger.

Not who was superior.

But who would shape the foundation of this new world.

Aiden clenched his fist.

Nihlus tightened his grip on his sword.

They moved.
