Reborn As a Villain Son With The Strongest Wife

◇◇◇

The Beast Evolution Stone pulsed in my hand.

Raw, unfiltered energy flowed through my body, linking directly to Ironhorn's soul.

He let out a deep, rumbling breath—

His massive body trembling, golden veins of power crackling across his hide.

[ Ironhorn is ready for Evolution. ]

A smirk formed on my lips.

"Then let's begin."

◇◇◇

An Evolution Unlike Any Other

Celestia tilted her head, golden eyes sparkling with amusement.

"Ara~ Are you sure you want to do this here?"

I glanced around.

The Ashen Caverns were still unstable after our battle.

The ground was cracked, molten heat rising from the depths.

The air hummed with lingering energy from the Evolution Stone.

But I had no time to waste.

Rael Ascarion would bond with his Sacred Griffin in two weeks.

If I wanted to keep up—

I needed Ironhorn's evolution now.

I placed the Evolution Stone on Ironhorn's forehead.

FWOOSH!

A pillar of golden light erupted, swallowing Ironhorn's entire body.

The cavern shook, dust and debris falling from the ceiling.

And then—

A system notification appeared.

[ Ironhorn is undergoing Forced Evolution. ]

[ Warning: This process is irreversible. ]

[ Will you proceed? ]

I didn't hesitate.

"Do it."

◇◇◇

The Evolution Process

Ironhorn's body began to change.

His muscles expanded, bones cracking and reforming.

His golden horn grew longer, pulsing with raw energy.

His once-dark hide turned a deep obsidian black, with glowing golden runes forming across his body.

Celestia's eyes widened slightly.

"Oh my~ This isn't a normal evolution…"

I narrowed my eyes.

She was right.

This wasn't just a rank-up.

Ironhorn was breaking through a limit—

Becoming something beyond ordinary beasts.

And then—

The system gave the final notification.

[ Evolution Complete. ]

The golden light shattered, revealing Ironhorn's new form.

◇◇◇

Ironhorn, the Indomitable Rhino

Ironhorn stepped forward.

The cave rumbled beneath his weight.

His massive frame was now covered in obsidian armor with golden streaks running through it.

His horn had doubled in length, glowing with immense power.

And his eyes—

They burned with intelligence and fury.

[ Ironhorn has evolved into the Indomitable Rhino. ]

A Mythical-Class Beast.

Not just a stronger version of his old self.

He had transcended.

Celestia's lips curled into a smirk.

"My, my~ With this, you've officially entered the realm of monsters, darling~"

I clenched my fist.

This was it.

The first step toward breaking fate itself.

I looked at Ironhorn—my first beast, my partner.

"Let's show the world what true power looks like."

And with that—

The era of the Indomitable Rhino had begun.
