one piece: gene extraction and fusion system-Chapter 321: Demon Flame Hell

"Hahahahaha."

On the ground, Saya climbed up and laughed excitedly. "Black Crow, do you feel it? This is my ability, hahaha."

"My flames are not only powerful but can also heal injuries and absorb the physical energy of the burned target for my own use," Saya hissed, a crazed smile on his face. "You will never be my match. Die!"

Saya laughed wildly, stepped forward, and the black flames on his body surged. Then he flew into the air, raised his hands, and the flames condensed into three black dragons circling above him.

In the next moment, the dragons roared and rushed toward Mio.

"Indeed a troublesome ability," Mio murmured, covering his left hand with Armament Haki and swiping it at the approaching flames, trying to extinguish them.

But the flames didn't go out.

Unless the ability user was killed, these black flames would continue to burn.

And while they burned, they drained his physical energy and transferred it to Saya.

This ability truly lived up to the mythical beast class—both unique and powerful.

"But your IQ may be a bit lacking," Mio remarked calmly. Armament Haki continued to coat his hand, resisting the burning effect. At the same time, he looked up at Saya and added, "Did you forget what just happened?"

"What?"

Sayar's expression instantly shifted. He seemed to recall something and instinctively activated his Observation Haki at full strength, scanning the surroundings and locking his gaze on Mio.

Mio, noticing the heightened vigilance, sneered with contempt. "No matter how careful you are, it's useless. In my domain, the result is always the same."

Snap.

A crisp snap echoed.

The replacement domain spread instantly.

With a mere thought—

Sayar's wings vanished, and his body plummeted from the sky.

The black dragons he'd summoned with the flames also instantly vanished.

"Damn it, this again!" Saya cursed inwardly, feeling his ability disappear once more and being replaced by some foreign power he couldn't even begin to control.

With a bang, Saya slammed into the ground. His new, unfamiliar ability faded as quickly as it came, and his original demonic power returned.

When he looked up, he noticed the black flames on Mio's hand had vanished.

"This guy's ability..."

Sayar's expression darkened.

It was his first real fight against the Black Crow, but the bizarre nature of Mio's powers had already unsettled him.

The sudden ability changes... the power to swap abilities...

They gave him an ominous feeling.

"Demon Dragon!" he roared. Without delay, Saya conjured black flames in his palm and launched them into the sky. The flames rapidly took shape, becoming a colossal black dragon that roared and dove toward Mio.

As the dragon charged, the air grew scorching.

Black wings extended behind Saya, and he soared into the air. Simultaneously, he formed another weapon—this time, a spear forged from black flames.

"You're destined to be my stepping stone to the throne!"

Mio remained unfazed. Clenching his right fist, he let the devil's power surge. A massive skeletal giant manifested around him, completely enveloping his body.

The towering demon skeleton extended its arm, grabbing the incoming flame dragon and smashing it with a single punch.

But even as the dragon was destroyed, its flames didn't vanish. Instead, they turned into snowflake-like embers that descended from the sky, latching onto the skeletal giant and burning continuously.

Mio ignored the flames. They weren't burning him directly, but rather the energy construct formed by the devil's power. Saya couldn't absorb energy from something that wasn't a living body.

Mio's gaze locked on Saya as the skeleton giant struck out again, aiming to crush him.

"Die, and I will become the new Emperor of the Seas!" Saya bellowed, thrusting his spear forward. As it launched, the spear enlarged, and the black flame tip spun violently like a tornado. freewēbnoveℓ.com

Puff!

The spear clashed with the skeleton giant's fist and actually pierced through, heading straight toward Mio at the core.

"Wishful thinking," Mio said coldly. With a thought, he vanished from inside the giant's body, and the giant dispersed into energy.

In the next instant—

Mio appeared behind Saya, his right fist already drawn back. With all his power focused into one devastating blow, he struck Saya in the back.

Boom!

The overwhelming force smashed Saya into the ground. The entire island trembled, dust rose into the air, and the impact split the ground with deep fractures.

Mio's expression didn't change. He stepped forward and punched again.

Boom. Boom.

The ground shook once more.

Saya's body sank even deeper into the crater.

As Mio was about to deliver another blow, black flames erupted from Saya's body and surged toward him.

Mio disappeared again with a thought, evading the flames.

Saya climbed out of the crater, wiping the blood from his mouth and spitting to the side.

"Black Crow, I admit you've surprised me. Your strength is greater than I expected. But I won't lose."

Taking a deep breath, Saya's wings reappeared, and his entire body was engulfed in black flames again. He began to grow rapidly, transforming in mere moments into a towering demon wielding a massive spear of flame.

At the same time, black flames surged from his body, spreading out across the sky.

In the blink of an eye, he had turned the entire battlefield into a sea of demonic fire.

The temperature spiked drastically.

Even Mio began to sweat under the heat.

He glanced around. Nearly every inch of the space was engulfed in flame, forming a terrifying hellscape.

"Heh."

Mio chuckled softly. He licked his lips, eyes gleaming with excitement—not fear.

"He really is worthy of being a contender for the throne. His strength is genuine. This fight won't end quickly, but that's fine. If he were too weak, it wouldn't be satisfying to kill him."

Buzz—

Mio clenched his right fist. The devil's power surged around him. Armament Haki and dragon power intertwined with it.

The skeletal giant returned once more, enveloping Mio's form. The combined energy forged a massive sword in the giant's hand. With a single swing—

A long, deep crack split the ground beneath them.
