Skill Tree Chronicles: One Piece

The midday sun blazed relentlessly, casting a scorching brilliance across the battlefield.

"INTRUDERS! DIE!"

Jack and Shen Yuan stood across from each other, eyes locked in grim silence.

"Jack," Shen Yuan said coolly, "still Kaido's lapdog?"

Jack gritted his teeth. "Damn brat! Starting off with insults already?!"

He didn't want to be here. He had already voted against this raid internally. But duty—no, loyalty—kept him grounded.

Still, Jack's fury ignited, and with a bellow, he transformed in an instant into a towering mammoth, surging toward Shen Yuan with unstoppable force!

Shen Yuan stood his ground, smirking faintly.

Behind Jack, Speed tensed with excitement, reaching for her bow to fire a quick arrow—only to feel a sharp gust of wind blow past!

The golden blade of a halberd roared like a predator, slicing down toward her mount's head.

"W-What?!"

Speed gasped.

"BASTARD! SHEEP HORNS!"

Sicilian's subordinate, Sheepshead, activated his Zoan powers, morphing his arms into curled ramming horns and charging forward!

"One-Sword Style: Black Rain!"

A sleek arc of sword light carved through the air—Sheepshead's horns were severed instantly, and blood sprayed in a fan-shaped burst.

At the same moment—

Enel's halberd pressed coldly to Speed's throat. His expression was dead serious.

"Move even slightly, and I'll take your head."

Speed froze in terror, letting her weapon drop.

Sheepshead writhed on the ground, screaming.

Tashigi stepped forward, adjusting her glasses with a metallic glint and placing her blade to his neck.

The Beast Pirates minions behind them trembled at the brutal efficiency.

Meanwhile—

In Shen Yuan's palm, a massive ivory tusk spun slowly, blood glinting on its edge.

He gazed at Jack, smiling with curious amusement.

"You damn little—!"

Jack clutched his face—his left tusk had been broken off.

"I'LL KILL YOU!"

With rage exploding, Jack raised his spiked kanabo and roared.

"HAAAGH!!"

Pfffssht—!

Shen Yuan hardened the stolen tusk with Busoshoku Haki, plunging it into Jack's chest with terrifying force.

Blood sprayed. Jack staggered.

"These tusks are more useful than I expected," Shen Yuan muttered.

Then, like a flicker of light, he vanished—reappearing instantly above Jack's head!

"Your death is here."

At that critical moment—

A burning black figure dove from the sky, foot blazing:

"FLAME EMPEROR!!"

BOOOM!!

The two silhouettes clashed midair with seismic force.

"How do you compare to that old man—Whitebeard?"

Jhin faltered—what the hell did that mean?

"You kill Jack, and Lord Kaido will chase you to the ends of the sea!"

Shen Yuan's expression hardened. His kick intensified.

After the collision, the two landed and separated. Jhin touched down first—calm, focused.

Clad in obsidian armor, long blade at his hip, and a halo of fire circling his head, he was unmistakable.

Lunarian.

"You're from the Lunaria Tribe, aren't you?" Shen Yuan asked.

Jhin's face twisted. "Shut your mouth. DIE!"

Although still wounded, Jack transformed once more into mammoth form, snarling with bloodlust.

In the blink of an eye, Jhin and Jack formed a pincer maneuver.

"Two-on-one?" Shen Yuan said, scoffing. "Why not call Kaido too?"

The commanders exchanged glances—Murder him.

"MAMMOTH CHARGE!"

Jack barreled forward. Jhin unsheathed his burning katana and launched.

"Then let's play!"

Shen Yuan flung his cloak aside—a striking white uniform underneath, tailored like a Marine's, but with a unique white sigil embroidered over the heart: Bai Tuan.

"BRAT!!"

SHHHHH—BOOM!

Jhin's burning slash collided with the Heaven-Swallowing Grid sword.

At the same time, Shen Yuan turned and lashed out with a devastating kick.

Jack was hurled meters away, crashing into the dirt in a heap.

Jhin drew back, wary.

"Shen Yuan... Why would the Bai Tuan target us, the Beasts Pirates?"

But then—dark mist crept in like a tide.

Jhin's instincts screamed. He spun, ready to take flight.

But red eyes were already locked onto him.

"Didn't you hear me?" Shen Yuan said coldly.

"I said, why not call Kaido?"

FLASH!

SHUNK!

A blade pierced through Jhin's abdomen.

"GAHHH—!"

Blood gushed from his mouth.

He stumbled backward, dropping to one knee, vision blurring.

"Damn it… I haven't even seen… Kaido-sama become Pirate King…"

Jhin collapsed, trembling, bleeding out.

"BROTHER JHIN!"

Jack's howl was primal.

He coated his mammoth frame with blackened Armament Haki, charging again.

"YOU'LL DIE HERE!"

Shen Yuan calmly pulled his blade free from Jhin's corpse.

Dark mist surged again.

"CRACK!!"

Jack's other tusk shattered cleanly.

A deep slash opened along his spine—seething with ghost-like black aura.

"URGHK!!"

Jack vomited blood, his Zoan transformation collapsing into his base form.

He squirmed helplessly in the dirt.

"Just trash."

Shen Yuan sheathed his sword with a click.

He glanced down at the crumpled commanders, smirking.

"What a waste."

[Mission Complete: Defeated Jack and Jhin. Level +1 → Level 94.]

"Not bad."

He clenched his fist and looked to the sky.

Something massive approached…

Far above, Kaido's expression twisted.

Sweat glistened down his scaled brow.

Two of his Commanders—their life cards were burning.

"YOU DAMN BRAT—YOU DIE HERE!"

Kaido roared in his dragon form and accelerated through the sky!

Meanwhile, Shen Yuan sat cross-legged, calmly munching on an apple beside the fallen bodies.

He opened his system interface.

Shen Yuan exhaled softly.

Still no Devil Fruit…

What a pain.

"I heard Admiral Kizaru's at Marineford…"

His eyes narrowed slyly.

"Maybe I'll drop by and 'borrow' that Sparkle Fruit someday."

From the side, Jhin—bound to a tree like a trophy—struggled to speak.

"Kaido… will avenge us… He'll… rip you apart…"

Tashigi and Qiong froze, images flashing in their minds.

This moment… felt like CP9 all over again.

"Oh?" Shen Yuan tilted his head.

"I sure hope Kaido shows up. Wouldn't want to miss the main course."

He grabbed Jhin by the throat and whispered.

"Believe me… I'm more than ready."
