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

Luffy's attacks rained down on Jack like a storm.

In his elastic form, each of his punches is imbued with the compressed elasticity of rubber to its limit and Armament Haki.

The fists flew from different angles, their trajectories so unpredictable that they were impossible to anticipate.

The Mink warriors watching the battle were dumbfounded.

The members of the Musketeer Squad who had just fought Luffy stared wide-eyed—

If this kid had used that state against them, they probably would have been lying on the ground long ago.

But Jack's face still showed no sign of strain.

He stood amidst Luffy's barrage of punches, his two curved swords flashing in a dense, impenetrable manner.

Each parry precisely hit the weakest point in Luffy's punch, the blade clanging crisply under the impact of the fist.

"Is that all?" Jack's tone was full of impatience.

Luffy didn't stop.

His attacks became faster and heavier.

In his fourth gear form, his stamina was depleted very quickly, but he couldn't care less about that now.

He knew that the guy in front of him was unlike any of the opponents he had ever faced before.

Kaido's Pirates, one of the Three Disasters.

Drought Jack.

Bounty: 1 billion Berries.

Enemies of this level cannot be suppressed by brute force.

After throwing countless punches, Luffy finally found an opening.

His right fist bypassed Jack's scimitar from the side and slammed into Jack's shoulder.

"Hit!"

Chopper jumped up excitedly, then looked on in astonishment.

Luffy also looked at his fist in surprise.

His punch, imbued with all his strength, slammed into Jack's shoulder with a dull thud.

But Jack's body remained completely still.

Jack's shoulder muscles only dented slightly before springing back like a spring.

It cannot break through the defense.

Luffy's eyes widened.

He withdrew his fist and saw that the Armament Haki on his fist was still there, but there wasn't even a bruise on Jack's shoulder.

"Finished?"

Jack looked down at Luffy, a ferocious grin spreading across his face.

Before Luffy could react, Jack's scimitar came slashing down.

Luffy's body was slammed hard into the ground.

Soil and gravel flew up, and a large crater several meters in diameter appeared on the ground.

Luffy lay at the bottom of the pit, his Gear Fourth form rapidly deflating after the heavy blow, his body shrinking quickly like a deflated balloon.

"Luffy—!!!"

Chopper and Usopp screamed at the same time.

Zoro and Sanji exchanged a glance, and simultaneously pushed off with their feet.

Zoro drew all three of his swords at the same time, their blades wreathed in a dark sheen from Armament Haki.

Sanji's right foot ignited with the flames of Diable Jambe, the intense heat distorting and blurring the surrounding air.

The two attacked Jack from the left and right.

"Three-Sword Style: Demon Slash!"

"Demon Wind Kick - Level One Meat Grinder!"

Zoro's three swords and Sanji's Flame Kick simultaneously struck Jack's waist and chest.

The blade scraped against Jack's skin, sending sparks flying, while Sanji's flames exploded into a fireball on his chest.

Jack was only knocked back two steps.

He glanced down at the still-burning flame on his chest, then at the three faint white marks on his side, his expression unchanged.

"Two more?"

The arrival of Zoro and Sanji brought about a subtle change in the battle.

Roronoa Zoro's three swords unleashed a dense barrage of slashes in the night.

Every slash landed precisely on Jack's body—neck, joints, abdomen, all theoretically vital areas.

Sanji's Diable Jambe, wreathed in blazing flames, relentlessly kicked Jack's ribs and the back of his knees, each strike accompanied by a dull thud.

But that's all.

The blade struck Jack, producing a crisp metallic clang.

The kick landed on Jack, producing a dull thud like bone hitting a metal plate.

Jack stood between the two men, his face showing extreme impatience, as if he were enduring two mosquitoes buzzing in his ear.

"It's annoying."

The curved blade swept across, and Zoro stepped forward to parry with his own blade, but he was sent flying by Jack's immense strength, crashing into a row of trees.

With a vertical slash of the curved sword, Sanji leaned back to the limit, the blade slicing across his forehead and severing several strands of his golden hair.

When the two regained their footing, they were both breathing heavily.

"What kind of monster is this?"

Sanji wiped the blood from his forehead.

"I kicked him at least twenty times, and he didn't even flinch."

"Even though Ancient Zoan-type Devil Fruit users are known for their defense, this is still terrifying."

Zoro tightened his grip on the Sandai Kitetsu.

"But his hardness—it's not as simple as ordinary Armament Haki."

Just then, Luffy got up from the ground.

The aftereffects of the fourth gear left him sore all over, but the fighting spirit in his eyes remained undiminished.

"Zoro, Sanji."

Luffy flexed his wrists.

"Let's go together."

A slight smile appeared on Zoro's lips.

Sanji threw the cigarette butt on the ground and stomped it out.

"I've been waiting for this for a long time."

The three people moved at the same time.

Luffy charged forward from the front, activating Gear Fourth again, but this time his size had shrunk a bit.

Zoro circled around to the left, wielding three swords in the starting stance of the Nine-Sword Style, targeting Jack's front leg joint.

Sanji dodged to the right, his right foot bursting into flames, aiming for the back of Jack's knee.

Attack from three directions, targeting three vital points simultaneously.

Jack's eyes finally showed a hint of seriousness.

Individually, these three brats wouldn't be enough to fill his teeth, but when they teamed up, they completely blocked all his dodge angles.

But that's all.

Jack took a deep breath and unleashed his full Armament Haki.

A black sheen emanated from his body, forming a layer of armor-like substance on his already hardened skin.

Luffy, in his Gear Fourth "Snake Man" form, slammed his fist into the armor, creating a deafening roar.

Zoro's three-sword slash struck the armor, sending sparks flying.

Sanji's Diable Kick struck the armor, leaving a charred footprint.

The armor remained completely still.

"It's my turn."

Jack's body began to spin.

The colossal creature, ten meters tall, spun rapidly in place, its curved blade forming a destructive storm.

All three were caught in it at the same time.

Luffy was sent flying by the elephant's trunk.

Zoro was slashed back by the curved sword.

Sanji was knocked over by the ivory.

The three people flew backwards in different directions like three bowling pins that had been knocked away, hitting the ground and kicking up three clouds of dust.

Usopp, Chopper, and Nami, who were in the distance, were already too frightened to speak.

"No, Luffy and the others will die if this continues!"

Nami's hand gripping the Clima-Tact was trembling.

"Franky! Robin! Brook! Let's go too!"

Without saying a word, Franky flicked out his iron fist and fired a volley at Jack.

"Weapon in the left hand!"

The shell flew toward Jack, leaving a trail of flame, and exploded in a burst of fire on his body.

Robin crossed his arms and summoned countless arms at Jack's feet, attempting to entangle his legs.

"A riot of flowers, a spider web!"

Brook drew the Soul-Slaying Sword, its blade gleaming with a chilling light.

"Song of Plunder: Blizzard Slash!"
