Cosmic Ruler - Chapter 519

Chapter 519: Fate XXXVIII
The sky cracked, the land trembled, and the very essence of this new world shifted as Aiden and the Firstborn clashed with full force.

For the first time, Aiden wasn’t just fighting to test someone.

He was fighting to push himself.

And the Firstborn?

It wasn’t just adapting anymore.

It was challenging him.

Every strike Aiden launched, the Firstborn met head-on.

Every counter it made, Aiden adjusted in an instant.

But something was different now.

The Firstborn’s movements no longer mirrored Aiden’s.

It had begun to create its own style.

Its void blade shifted between forms, changing mid-attack, feinting, overwhelming, disrupting rhythm.

Aiden dodged, twisted, and countered, golden energy flaring with every movement.

Damn.

This thing is evolving faster than anything I’ve ever seen.

But that only made him grin.

Because, for the first time in a long time—

He felt exhilarated.

The Awakening of the Firstborn

The Firstborn’s form stabilized even further.

Its body, once shifting and undefined, now held a solid presence.

Not fully human.

Not fully divine.

Something entirely new.

Its eyes—once empty—now glowed with its own light.

And in that moment, Aiden knew—

This wasn’t just an opponent.

This wasn’t just a test.

This was the first rival of his new reality.

The Firstborn’s voice rang out, steady and certain.

“You are strong, but I will surpass you.”

Aiden grinned.

“Then come and try.”

They moved at the same time.

The air cracked apart as they met in the center, golden energy and void energy colliding in an explosion that shook the entire realm.

And at that moment—

The Firstborn unleashed something new.

A technique Aiden had never seen before.

A move that belonged to no one but itself.

“Void Rebirth.”

Aiden’s eyes widened.

The Firstborn’s blade vanished for an instant—then reappeared behind him, as if reality itself had reset.

—𝘊𝘙𝘈𝘊𝘒—!

Aiden barely managed to twist away, golden flames bursting from his body to absorb the attack.

But the moment he dodged—

The Firstborn was already attacking again.

Faster.

Sharper.

Its strikes now impossible to predict.

Aiden laughed.

“Now you’re getting serious.”

And he stepped forward, golden light igniting across his entire body.

“Then I guess it’s time to show you what I can really do.”

The sky ripped apart, the newborn land trembled, and the very fabric of this reality twisted under the force of their battle.

Aiden burst forward, golden flames surging as he met the Firstborn’s strike head-on.

Their clash sent shockwaves tearing through the world, reshaping mountains and carving new landscapes with every exchange.

For the first time, Aiden wasn’t holding back.

And the Firstborn?

It wasn’t just reacting anymore.

It was forcing him to adapt.

The Evolution of Combat

Aiden dodged as the Firstborn’s Void Rebirth activated again—its blade vanishing and reappearing from impossible angles.

But Aiden had already seen through it.

—𝘍𝘞𝘖𝘖𝘖𝘚𝘏—!

He twisted his body at the last second, golden energy surging as he countered with a technique of his own.

“Void’s tricky, but let’s see how you handle this—”

His hand shot forward, gripping the air itself.

“Gravity Collapse!”

—𝘊𝘙𝘈𝘊𝘒—!

The Firstborn froze for a split second as the space around it compressed, pulling it inward.

Aiden didn’t hesitate.

He closed the distance instantly, golden flames wrapping around his fist as he launched a devastating strike.

“Let’s see how you evolve from this!”

—𝘉𝘖𝘖𝘖𝘔—!

The hit landed.

The Firstborn was blasted back, crashing into the newly formed mountains, sending shattered rock and energy waves spiraling outward.

Aiden exhaled, shaking his fist.

“Damn. That actually hurt my knuckles.”

But before he could finish his thought—

The dust erupted.

A dark flash tore through the air—

And the Firstborn reappeared.

Faster.

More precise.

And for the first time—it was smiling.

“I understand now.”

Aiden’s eyes narrowed.

“Oh?”

The Firstborn’s void energy pulsed, stabilizing further.

And then—

It did something new.

It reached out—not just physically, but conceptually.

It was no longer just learning from Aiden’s movements.

It was stealing his concepts.

Aiden’s golden flames flickered—

And for the first time—the Firstborn’s own energy changed.

The void around it crackled with golden embers.

A perfect fusion of Aiden’s power and its own.

Aiden grinned.

“Well, damn.”

“You just stole my power.”

The Firstborn raised its blade, now glowing with golden fire and shifting void energy.

It had taken everything it learned—and evolved past it.

Aiden rolled his shoulders, excitement flashing in his eyes.

“Guess I’m gonna have to get creative, then.”

They charged at each other again.

And this time—

It wasn’t just a battle.

It was the beginning of something far greater.

The battle escalated, tearing across the newly formed landscape, shaping the world with every clash.

Aiden moved first, golden flames igniting around his body as he shot forward.

The Firstborn matched him step for step, its own energy—a fusion of void and stolen golden fire—surging in response.

Their movements blurred across the battlefield, too fast for anything to keep up.

Each clash of their blades reshaped the sky.

Each impact carved mountains into existence.

Each counter, dodge, and strike rewrote the very laws of physics in this reality.

And Aiden couldn’t stop grinning.

It’s not just keeping up anymore.

It’s pushing me.

No… it’s surpassing me.

A New Power is Born

The Firstborn’s form had changed.

Its once-undefined features were now distinct.

No longer just a shifting entity.

No longer just a mimic.

It had taken Aiden’s golden energy, fused it with the void, and transformed it into something unique.

“You said I stole your power.”

The Firstborn raised its sword, its void energy now burning with a brilliant, otherworldly light.

“But it is no longer yours.”

Aiden chuckled, shaking out his wrists.

“Damn. Now that’s what I like to hear.”

For the first time—

The Firstborn was no longer learning from Aiden.

It was creating something entirely its own.

And then—

It attacked.

—𝘍𝘞𝘖𝘖𝘖𝘚𝘏—!

The Firstborn vanished, reappearing instantly behind Aiden—

Its sword now carrying something new.

A concept Aiden had never seen before.

“Voidfire Rend.”

The moment the words left its mouth—

A blade of pure severance slashed toward Aiden, burning with both destruction and rebirth at once.

A power that didn’t just cut.

It erased and remade in a single motion.

Aiden’s instincts screamed.

I can’t block that.

He had only milliseconds to react—

So he did what he did best.

He adapted.

—𝘊𝘙𝘈𝘊𝘒—!

At the last second, he twisted his body, golden flames exploding from his palm.

“Primal Shift!”

Instead of resisting the attack, he flowed with it.

His body bent with the force, golden energy redirecting the impact instead of meeting it head-on.

The Firstborn’s attack sliced through empty air—

And Aiden countered instantly.

“Golden Fang!”

A single devastating punch landed square in the Firstborn’s chest, sending a shockwave through its body.

—𝘉𝘖𝘖𝘖𝘔—!

The Firstborn was blasted backward, skidding across the battlefield before landing gracefully, voidfire still flickering around it.

And then—

It laughed.

Aiden blinked.

Then he grinned.

“So, you’ve got a personality now too, huh?”

The Firstborn tilted its head, eyes burning with new understanding.

“I was born to be your reflection.”

“But now, I am something else.”

Its form solidified completely.

A being that was once undefined—

Now stood with absolute certainty.

“I am more than just Firstborn.”

“I am the one who will stand as your equal.”

Aiden exhaled, golden flames rising as he took his stance once more.

“Then show me.”

They moved at the same time.

And with that—

The battle entered its final stage.
