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

The Ark Proverb flew in the clouds for a full day and night.

Roy stood at the bow of the ship, holding a permanent pointer that pointed directly at the entrance to the Grand Line—Reverse Mountain.

"Boss, are we really not going to travel through the Calm Belt?"

Tezzolo leaned against the ship's railing, toying with a gold coin in his hand.

"Why bother with all that trouble? Why not just let the Ark Proverb fly over there?"

Roy glanced at him: "What do you know? Only those who traverse upside-down mountains are proper pirates."

"Exactly!"

Yamato hopped over, carrying a spiked club, his eyes shining like light bulbs.

"I've wanted to try climbing Upside Down Mountain for a long time."

"I heard the water flows like a waterfall, rushing up and then rushing down!"

Pea's face paled: "Rushing...rushing down?"

"What are you afraid of!" Yamato put his arm around Pea's shoulder. "Roy's here!"

Roy smiled, activated his telekinesis, and the Ark Maxim began to descend slowly.

The golden hull of the ship pierced through the clouds, and the view on the sea gradually became clearer—

In the distance, a vast red earthen continent stretches between the sea and the sky, like an endless red wall.

The Upside-Down Mountain is embedded in this wall, with five huge waterways flowing down from the top of the mountain, causing seawater to flow backward and creating a spectacular sight of flowing upstream.

"Wow—" Yamato's mouth dropped open. "This is Upside Down Mountain?"

Savile, Charon, and Bages all crowded to the side of the ship, craning their necks to look ahead.

Enel floated in mid-air, slung his golden staff over his shoulder: "Yehahaha, this is the first time I've ever seen Upside Down from the sea!"

Kazami sat cross-legged on the deck, his hand on the hilt of his sword, expressionless, but his eyes were glancing in that direction.

Barr scratched his head sheepishly. "Captain, with this upward current, won't the boat capsize?"

"It can't be turned over," Roy said calmly. "Everyone's standing firm."

As soon as he finished speaking, the Ark Proverb landed steadily on the sea.

The moment the boat hit the water, the spray from the waves splashed all over Savi's head and face.

"Pfft—" Savi wiped his face. "Boss! Couldn't you be a little gentler?"

Roy ignored him, using his telekinesis to propel the boat toward the Upside-Down Mountain Waterway.

As you approach the waterway entrance, the current begins to become rapid.

The Ark Maxim was like a golden leaf, pulled by a tremendous suction force, rushing towards the upstream waterway.

"It's here, it's here, it's here!" Yamato jumped up and down with excitement.

The bow suddenly lifted, and the entire ship charged upwards along the almost vertical waterway!

Water surged from both sides, splashing onto the deck like a torrential downpour.

Pea clung tightly to the railing, her little face pale, her eyes tightly shut.

Yamato stood at the bow of the ship, arms outstretched, roaring, "Hahahaha! Awesome! So awesome!"

Enel floated above the ship, waved his hands, and clouds surged from his palms, swirling around the ship.

To prevent the ship from crashing into the surrounding rock walls.

Seeing this, Tesoro's body crackled with electricity, propelling the Ark Maxim to a sudden increase in speed—whoosh!

The ship broke through a giant wave, splashing water all over Savi's head and face.

"Hello!"

"Tezzolo!"

"You did this on purpose!" Savi roared.

"Hehe! I didn't do it on purpose!" Tesoro chuckled, looking smug.

Savi was so angry that he wanted to rush up and punch him, but the boat rocked again, and he staggered a couple of steps, almost falling over.

Charon grabbed him and said, "Stop fooling around, stand still."

Luo stood at the ship's side, gripping the railing tightly with both hands, his eyes showing a mixture of tension and excitement.

He grew up in Beihai and had never seen anything like it before.

The waterways of Upside Down Mountain are like stairs leading to the sky.

The moment Ark Proverb reached the summit, the entire ship took to the air.

At that moment, everyone saw it—five waterways converged at the top of the mountain, forming a huge cross.

The seawater gathers here, then splits and flows down to the seven directions of the Grand Line.

"So beautiful..." Pea murmured as she opened her eyes.

The next second, Ark Maxim plunged headfirst into the descending waterway and plummeted downwards!

"Aaaaaahhhhhh—" Pea screamed.

"Hahahaha—" Yamato laughed wildly.

"Yehahaha—" Enel laughed even harder.

Roy stood at the bow of the ship, his telekinetic powers steadily supporting the hull, a smile playing on his lips.

This kind of excitement is much more interesting than flying in the sky.

The Ark Proverb burst out of the waterway and glided smoothly into the sea above Twin Capes.

The ship was still rocking slightly when Yamato jumped onto the gunwale, hands on his hips: "That was so much fun! Let's do it again!"

"No!" Pea's legs went weak.

Roy ignored them, his gaze fixed on the sea ahead.

There, the sea is rising.

It wasn't a wave—something enormous was rising from the water.

"All personnel on high alert."

Roy's voice wasn't loud, but everyone heard it.

Yamato immediately gripped his spiked club, while Savi and Burgess stood on either side of the ship's gunwale. Enel floated into the air, his golden staff held horizontally in front of him.

Kazami stood up and placed his hand on the hilt of his sword.

Baal picked up an iron ingot, ready to smash it at any moment.

The sea level rose higher and higher, forming a huge water bubble. Then—

boom--!!!

A giant black whale burst out of the water!

The whale was ridiculously large; the Ark Maxims looked like a leaf in its presence.

Its forehead was covered with crisscrossing scars, like a huge net.

Seawater cascades down its body, forming waterfalls.

It raised its head and let out a long, mournful cry.

"Moo————"

The sound was deep and desolate, echoing across the sea and making everyone's chest feel heavy.

"So...so big..." Pea tilted her head back, her mouth wide open enough to fit a fist.

Yamato gripped his spiked club tightly: "Is this guy an enemy?"

Roy shook his head: "No."

He had seen this whale before—in the original story.

Laboon, the island whale, is a member of the Rumbar Pirates.

In order to wait for its master's return, it crashed into the red earth for fifty years, leaving it covered in scars.

The mournful cries still echoed across the sea.

Lab's huge eyes stared blankly in the direction of Upside Down Mountain, as if he were waiting for someone.

Luo frowned.

His Observation Haki sensed that there was a life force within Labun.

"Boss!"

"There's someone inside its body."

Tesoro's Observation Haki also sensed the anomaly.

Roy nodded: "I know."

He raised his hand and used his telekinesis to probe into Labu's body.

Sure enough, in the stomach area, there was a modified space—there were lights, tables and chairs, and even a few potted plants.

"Mr. Crocus,"

Roy's voice entered Laboon's body through telekinesis.

"Come out and meet the guests."

A moment later, Rab's enormous mouth slowly opened. An old man wearing a floral shirt and round-framed glasses walked out.

His hair was gray, but he stood ramrod straight, holding a newspaper in his hand, his expression as calm as if he were taking a walk in his own yard.

"What's all the noise about?"

The old man walked to the top of Labu's head, sat down cross-legged,

"I was just thinking of taking a nap."
