One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

The group left the casino and arrived at the vast desert outside the rain-soaked land.

Under the blazing sun and amidst the swirling yellow sand, the Sand-Sand Fruit user was perfectly positioned to unleash their full power.

"Who wants to go first?"

Crocodile threw off his cloak, puffed on a cigar, and said arrogantly.

"cut!"

"How arrogant!"

Tesoro stepped forward, curling his lip in disdain.

Seeing this, Crocodile stopped talking and transformed his hands into sand blades, slashing straight at Tesoro.

"Whoosh~"

Tesoro dodged the attack like lightning, and then struck back with a bolt of lightning.

The two moved at high speed through the desert, where sand and lightning intertwined.

Roy carefully observed Crocodile's fighting style and soon discovered something unexpected—Crocodile...

Rock Dale can actually use two types of Haki!

Although his Armament Haki is still very rudimentary, and his Observation Haki is only at a beginner level.

But this does prove that Crocodile is talented.

"strangeness……"

Roy murmured,

"Now that you've already mastered Haki, why didn't you use it when you fought Luffy?"

Could it be that Crocodile's resolve was shaken after his failed challenge against Whitebeard?

They pinned all their hopes on finding the ancient weapon "Pluto".

Without the heart of a strongman, one's domineering aura naturally diminishes or even disappears.

On the battlefield,

Tesoro and Crocodile are locked in a fierce battle.

Crocodile leveraged the desert environment to maximize his advantages.

It can transform and manipulate sand at any time, forming sand whirls and sand blades with fierce attacks.

Tesoro's lightning is even more powerful in the arid desert.

Each lightning strike blasts a deep, charred crater into the sand, filling the air with ozone and the smell of burning.

"Sandstorm!"

Crocodile clasped his hands together, and a massive sandstorm rose from the ground, sweeping towards Tesoro.

This technique is not only incredibly powerful, but it also allows the user to continuously absorb sand grains in the desert to grow stronger.

Tesoro's eyes narrowed, and he raised his hands high: "Thunderous Welcome - Thousand Birds!"

Countless bolts of lightning struck down from the sky, converging into a giant lightning bird that swooped down towards the Sand Tornado.

The two forces collided in mid-air, producing a deafening roar.

Lightning and sand intertwined, and the entire desert trembled.

Barrett, who was watching the game, stroked his chin.

"This sand crocodile is quite capable; its Logia-type ability definitely gives it an advantage on home turf."

Hawkeye watched calmly.

"Tezzolo didn't use his full strength."

If his Rumble-Rumble Fruit were to unleash its full power, this level of sand wouldn't be enough to stop it.

Indeed, Tesoro was only using the basic techniques of the Rumble-Rumble Fruit in the fight.

The true power of the Rumble-Rumble Fruit has not yet been revealed.

This was something Roy had specifically instructed him to do before setting off.

This is mainly to demonstrate strength and intimidate Crocodile, not to kill him.

On the battlefield,

Crocodile grew increasingly alarmed as the fight progressed.

He had thought he would have an absolute advantage in the desert, but the speed and power of the lightning user in front of him exceeded his expectations.

What made him even more uneasy was that his opponent seemed to be handling the situation with ease and had not yet used his full strength.

"The Desert Sword!"

Crocodile's right arm transformed into a giant sand blade, slashing towards Tesoro.

This attack was extremely fast and covered in Armament Haki, so ordinary Devil Fruit users wouldn't have time to transform into their own element to dodge.

But Tesoro merely chuckled, his body dissipating into lightning before reforming a dozen meters away.

"Too slow."

Tezzolo shook his head.

"Your Haki training is still incomplete, and your Observation Haki can't predict my movements."

Crocodile gritted his teeth, a sense of humiliation welling up inside him.

He roamed freely in the first half of the Grand Line. When has he ever been looked down upon like this?

"Don't look down on people!"

Crocodile placed his hands on the ground.

"The Cycle of Erosion!"

Centered on him, the desert began to change dramatically.

The sand became drier and sharper, the ground cracked rapidly, and the moisture was completely drained.

Change the environment to make the entire area Crocodile's home ground.

Tesoro sensed a sharp decrease in moisture in the surrounding air, which affected the conduction of lightning.

He frowned, knowing he couldn't continue playing this game.

"That's about it."

Tesoro clasped his hands together, lightning flashing in his eyes.

"Let me show you what real lightning is."

"Billion-Volt Thunder Dragon!"

A colossal dragon composed entirely of lightning soared into the sky from behind Tesoro, its body crackling with raging arcs of electricity.

The longan fruit resembled two thunderballs, radiating a chilling aura.

This is a technique Tesoro developed during his training on Raijin Island, combining the power of the Rumble-Rumble Fruit with his control over it.

Crocodile's expression changed drastically; he could sense the terrifying energy contained within the thunder dragon.

If hit, even a Logia-type elementalist would be severely damaged!

"The Desert Diamond Sword!"

Four enormous sand blades rose from the ground, slashing at the Thunder Dragon in a crisscross pattern.

This is Crocodile's strongest attack to date, with the sand blade covered in dense Armament Haki.

Rumble—!

Lightning collided with the sand blade, unleashing a blinding light.

The desert was blasted into a giant crater with a diameter of 100 meters, and the shock wave leveled the surrounding sand dunes.

When the smoke cleared, Crocodile knelt on one knee, panting heavily, blood trickling from the corner of his mouth.

His four sand blades were all shattered, while Tesoro's thunder dragon, though much dimmer, still hovered in mid-air.

High judgment.

"Shall we continue?"

Tesoro dispelled the thunder dragon and dusted off the sand.

Crocodile struggled to his feet, his eyes filled with resentment.

But he knew he had already lost.

Playing on home soil in the desert, they gave it their all, but couldn't even force the opponent to reveal their trump card.

"Step back, Tesoro," Roy's voice came.

Tesoro nodded and transformed into lightning, returning to Roy's side.

Crocodile clenched his fist as he watched Roy approach.

"They've changed the person."

Roy nodded to Barrett.

"you go."

Barrett grinned and strode towards Crocodile.

"Kid, that's enough warm-up. Now I'll show you what a real fight is like."

Before Crocodile could react, Barrett had already vanished from the spot.

It's not about shaving, it's about pure speed!

The next instant, Barrett appeared in front of Crocodile, his fist, covered in Armament Haki, aimed straight at his face.

too fast!

Crocodile barely managed to become an elemental, but Barrett's fist seemed to have anticipated his movements.

The trajectory changed the instant he transformed into an element, and it struck him squarely in the chest.

boom!

Crocodile flew backward like a cannonball, carving a furrow tens of meters long in the desert.

He coughed up a mouthful of blood and felt that at least three of his sternum bones were broken.

"Is this your Observation Haki?"

Barrett scoffed.

"Too weak. True Observation Haki allows one to foresee the future and see through everything."

Crocodile struggled to his feet, pressing his hands to the ground: "Sandstorm!"

A sandstorm swept up from the sky, obscuring the view.

But Barrett simply closed his eyes and unleashed his full Observation Haki.

"Found it."

Barrett flashed into the sandstorm.

Crocodile was hiding in the sandstorm, preparing to launch a sneak attack, but he didn't expect Barrett to find his location directly.

"Finger Pistol - Overlord Haki Enveloping!"

Barrett thrust out a finger, its tip wreathed in dark, domineering energy and crimson lightning.

The attack was as fast as lightning, and Crocodile had no time to dodge it.
