one piece: gene extraction and fusion system-Chapter 215: Unstoppable Hei Yan, The Flame of Death

"Go." On the Black Glory, Mio gestured toward Hei Yan.

Hei Yan nodded immediately, showing his understanding. After following the adults for so long, he had already become adept at interpreting their orders.

Suddenly, Hei Yan leapt lightly into the air, soaring skyward. His feet stepped across the sky as if walking on invisible platforms, swiftly heading toward Crow Island.

"That's... Master Hei Yan!"

"Master Hei Yan has taken action. Those bastards are finished for sure!"

"Tch, I wanna kill too, but there's no command from Master Hei Yan."

Several pirates voiced their thoughts one after another, some even expressing frustration at not being allowed to join the fight.

But then, most of them fell silent in awe.

High in the sky, Hei Yan activated Geppo (Moonwalk), and his eyes shimmered with an eerie glow. As his pupils spun, a massive skeletal giant condensed around his body—Susanoo enveloped him completely.

A moment later, black flames surged around the skeleton and condensed into a pair of massive, flapping black wings. With a powerful beat, he propelled himself toward Crow Island like a divine executioner.

"Is this also Lord Hei Yan's ability? Is he... is he some kind of Mythical Zoan user?" Araki muttered in shock, his eyes wide. The ability was far too mystical to seem real.

Within seconds, Hei Yan had reached Crow Island. His sharp gaze locked onto Kasai Ling, and without hesitation, Susanoo dove with overwhelming might.

Two massive black flame swords formed in Susanoo's hands and swung down with immense power.

"Damn it!"

Kasai Ling, already in his Zoan form—a beastman hybrid of a dog from the Dog-Dog Fruit—was no ordinary opponent. Though just a standard animal-type Zoan, his true strength came from his immense physical prowess and masterful use of Armament Haki.

With both hands shaped like claws, Kasai Ling struck upward, slicing through a barrage of crows as they fell, turning into black feathers and corpses.

But when he looked up and saw the colossal Susanoo charging down on him, his pupils shrank in alarm. He immediately counterattacked, launching a violent air blade from his claws.

Whoosh!

Hei Yan swung Susanoo's sword effortlessly, smashing the air blade to pieces. The black flame sword continued downward without losing momentum.

Kasai Ling sensed an overwhelming danger and dodged with a quick leap.

The ship's deck where he had stood shattered into splinters as the slash hit, engulfed in unquenchable black flames that spread like a plague.

The terrifying display made Kasai Ling's eyes twitch. Deep inside, he began to feel fear... and regret. He realized now how fearsome the Black Crow Pirates truly were. But retreat was no longer an option.

"Bring the ships closer! Kill them all!" Kasai Ling roared, sending out another sweeping claw slash that decimated the nearby murder of crows.

Screams echoed. Pirates fell, one after another, torn apart by Kasai Ling's attacks. But even more enemies remained, and his subordinates obeyed, steering their ships toward the Black Glory.

"You dare approach the adults?" Hei Yan's voice was filled with disdain and bloodlust. Controlling Susanoo, he raised the massive sword and slashed with full force.

Boom—!!

A thunderous explosion rang out.

Susanoo, like a demon god, flew through the air. With one devastating slash, a pirate ship was cleaved in two and erupted into flames and splinters.

Hei Yan's eyes locked onto Kasai Ling again. With a beat of his wings, he charged once more.

Another black flame sword came down.

Kasai Ling felt death looming. The black flames triggered an instinctive terror in him. He dared not block it head-on and dodged once again.

He lunged upward and tried to close in on Hei Yan. With a fierce roar, his claw slashed at Susanoo.

But—

Clang!

His full-powered attack landed... and did nothing.

"What... impossible!" Kasai Ling's eyes widened in disbelief. His strongest strike hadn't even left a scratch.

"Trash," Hei Yan sneered coldly. His kaleidoscope eyes spun ominously. A flame ignited from nothing and wrapped itself around Kasai Ling's right arm—Amaterasu.

"Aaaargh!!"

Kasai Ling screamed in agony.

The black flames bit into his flesh. He quickly tried to extinguish them—coating his arm in Armament Haki and ripping away his burning clothes.

But the flames wouldn't go out.

The fire consumed his Haki defenses as well, digging deeper and deeper into his body, causing unimaginable pain.

Suddenly—

Whoosh!

A sharp air-breaking sound tore through the scene.

Kasai Ling endured the agony and twisted his body, punching backward.

A tentacle, clad in Armament Haki, whipped through the air toward him.

Bang!

He blocked the first.

But schlick—another tentacle emerged from nowhere and pierced straight through his abdomen.

Blood spurted from the open wound.

Pain swept through him like a tide, and he briefly lost consciousness.

Taking full advantage, Hei Yan unleashed more of his terrifying black tentacles.

Puff!

Puff!

Tentacles pierced Kasai Ling's torso repeatedly, each strike more brutal than the last. Blood sprayed across the deck. Before long, Kasai Ling's beastly form collapsed, and he reverted to his human state, gasping and pale, barely clinging to life.

With a wave of his hand, Hei Yan dispelled one of Susanoo's flame swords and reached out with the giant hand, grabbing the dying Kasai Ling.

Then, the black wings flapped again as Hei Yan soared toward the Black Glory.

While flying, he called out loudly, "Hanba, I leave it to you! Finish them quickly!"

Roar—!!

A ferocious roar echoed from beneath the sea.

"What was that...?" Araki's eyes widened as a ripple of excitement passed through him. "That voice... it must be one of the giants of the Black Crow Pirates! Is Hanba finally appearing?!"

He'd long heard rumors of Hanba, the monster lurking beneath the waves, but had never seen him. That moment had finally come.

A shadow emerged on the surface of the ocean.

Then, with an earth-shaking crash, a monstrous figure burst out of the water. Towering, crimson-skinned, and with a face full of rage and savagery—it was Hanba.

With a roar, Hanba raised his massive arm.

Buzz...

An overwhelming Armament Haki burst forth, coating his giant arm like an armor of death.

RUMBLE—!!

The arm came crashing down on a nearby pirate ship.

In an instant, the vessel was annihilated—shattered into debris, reduced to flotsam under Hanba's sheer might.
