Skill Tree Chronicles: One Piece

On an unknown island,

At this moment, Shen Yuan and Whitebeard stood face to face.

"Gurarara! Are you ready, little brat?"

With those words,

Before Shen Yuan could respond, a terrifying wave of Haoshoku Haki (Conqueror's Haki) suddenly burst out from Whitebeard!

Shen Yuan instantly responded, releasing his own formidable aura to clash head-on!

Black and white Haki surged through the air, violently colliding—causing the trees around them to tremble and sway!

"Gurarara! Come at me!"

Whitebeard lifted his naginata, Murakumogiri, and leapt high into the air.

He swung down ferociously at Shen Yuan!

Shen Yuan drew his Heaven Devouring Sword, meeting the strike directly.

The two locked into a powerful clash!

Brilliant Haoshoku Haki sparks in the form of red-black lightning cracked and snapped between them!

"What a monstrous clash," someone watching murmured as the intensity of the battle escalated.

Shen Yuan broke the clash,

Reaching out to grab Whitebeard's neck—only for Whitebeard to casually knock his hand aside.

Then, Whitebeard's fist shimmered and compressed the air—Gura Gura no Mi!

A quake shockwave exploded forward like a thunderstorm!

Shen Yuan's Kenbunshoku Haki (Observation Haki) sensed the danger in time,

He shifted with Soru, dodging the full force of the quake punch and retaliated with a rising uppercut!

Whitebeard tilted his head—bam!—the fist grazed his face!

"Bring it on!" Whitebeard shouted, and the two began a brutal, close-quarters exchange!

The impact of their fists echoed across the island, along with fierce shouts!

"Brat! That all you got?"

"You too, old man!"

A massive shock burst out!

Whitebeard's Murakumogiri came crashing down again, coated in Busoshoku Haki (Armament Haki), overflowing with raw power.

It aimed directly at Shen Yuan's head!

His face hardened.

He immediately cloaked it in Haki—bam!

"Guhh!" Blood sprayed from his mouth!

But he endured the hit and returned with a thunderous punch to Whitebeard's face—like a launched cannonball!

Clang!

Fist and blade clashed again, red lightning flared violently!

"Still sturdy, old man!"

Shen Yuan smiled despite the pain. His Undying Vajra Physique rapidly regenerated his internal damage.

With the Heaven Devouring Sword resting behind his back, he launched a blazing whip-kick, slashing Whitebeard's cheek!

"Ugh!"

Whitebeard staggered several steps back, blood seeping from the corner of his mouth.

"Well done. Gurarara!"

Whitebeard plunged Murakumogiri into the ground and extended both arms—

CRACK!

Space itself fractured. He pulled the air as if tearing reality.

"Try this!"

The ground beneath Shen Yuan's feet vibrated ominously—it wasn't just tremors, but dimensional disruption!

"So this is the World's Strongest Man..."

Shen Yuan took to the sky using Geppo (Moonwalk), kicking downward repeatedly.

Whitebeard stepped forward—

BOOM!!

The ground shattered. A massive quake surged through the island, tearing it apart!

With a roar, Whitebeard launched himself skyward, Murakumogiri back in hand, and slashed at Shen Yuan!

Clang!

Under his sharpened Kenbunshoku Haki, Shen Yuan foresaw the trajectory.

He used swordsmanship to counter—yet even still, the aftershock sent him flying over ten meters!

This was Shen Yuan's newly developed advanced Observation Haki, a form of Future Sight.

He called it: "Future Trial and Error."

He could simulate future decisions, adjusting his choices mid-battle.

Now he had a decision to make—

To wound Whitebeard, he needed a trump card!

"Enough warm-up."

He drew the Heaven Devouring Sword, as black and crimson demonic energy erupted from it.

From behind him, two ethereal apparitions manifested—

One representing Life.

The other representing Death.

"Ghostly Three-Sword Style—Threefold Encirclement!"

The apparitions moved with him, surrounding Whitebeard.

All three raised their weapons high—gathering destructive energy.

BOOM!!

The impact this time dwarfed all previous clashes!

A shockwave burst forth, flattening trees, smashing boulders, turning terrain into rubble!

Whitebeard responded with quake punches—shattering the black mist!

"Ghuhh!!"

Still, the two ghostly figures slashed across his chest—leaving deep, bleeding wounds!

Whitebeard's grin didn't falter.

He'd seen cursed swords, sure—but this one? This was something new.

"This blade... is it already a Kokuto?" (Supreme Grade Black Blade)

A youth wielding something like this?

It was shocking. And terrifying.

Whitebeard furrowed his brows, gripping his blade tighter.

BOOM!!

They clashed again—both ghostly avatars thrown back.

Both fighters remained locked in a deadly gaze.

Blood streamed down Whitebeard's abdomen.

"Hahahaha! Still with me, old man?"

Shen Yuan's body was beaten, torn—though his Immortal Physique mended slashes quickly, the internal quake damage lingered like shattered glass inside.

It felt like his insides were being churned into milk-soaked cookies.

"Cough... cough..."

Whitebeard wiped his mouth, blood trickling from his teeth.

In the distance, Shen Yuan stood with his sword on his shoulder, eyes like burning stars.

"You're a cocky brat, huh?"

Whitebeard grinned, ignoring the wounds.

"Let's see how much more you've got!"

Elsewhere, the members of the Shen Yuan Adventure Group watched, stunned.

Completely stunned.

"What a monster brawl!!"

Enel clenched his fists, thunder sparking off him—he looked like he wanted in!

"Unreal!"

Marco forgot his wounds, watching intently.

Now, both combatants sheathed their weapons.

They understood that another blade clash might kill them both.

Bang!

Shen Yuan launched a punch into Whitebeard's jaw—knocking him back a few steps!

"BRAT!!"

Pow! Whitebeard counterpunched Shen Yuan's face with a backhand!

"Ora ora ora ora!!"

Shen Yuan retaliated with a barrage of rapid-fire punches!

The ping-pong of fists echoed louder than cannonfire.

"Damn it, Lao Deng! Take this!!"

Whitebeard stood unmoving, letting Shen Yuan's punches hit his torso!

After a few seconds—

"My turn!"

WHAM! A punch knocked Shen Yuan's head to the side!

"Then take mine!!"

Shen Yuan reeled back—then slammed a blow like a crashing meteor!

"Justice from the heavens!"

Like a tiger pouncing, the force of his punch shook the air!

"Hmph! You brat—it's my turn again!!"

And so they brawled—a turn-based fist-fight between monsters!

---

"What do we do about this...?"

Vista looked to Marco.

Marco's expression darkened.

"...You want to try stopping them?"

Vista shivered.

"Nope."

"Then shut up and count the rounds."

Vista wisely stayed silent.

"Take my uppercut!!"

Whitebeard roared, sending Shen Yuan rocketing into the sky!

"Lao Deng, quit copying me!"

Shen Yuan dropped like a meteor—

"Heaven-Falling Fist!!"
