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

Roy glanced at him sideways, his tone slightly mischievous.

"You are a Zoan-type Devil Fruit user. Dive into the sea a hundred meters deep and carry a warship that is dozens of times larger than a warship."

"Do you want to go and die, or do you want to be a ballast for Hades?"

Kaido froze.

Devil Fruit users must not touch seawater; this is an ironclad rule.

Although he was tough and thick-skinned, he still sank to the bottom if he fell into the sea.

"What should we do then?"

Kaido frowned.

"We can't possibly break through the encirclement wall of Wano Country, can we?"

Although breaking through the encirclement wouldn't be difficult for Lao Tzu with his strength, it would take too much time.

Furthermore, without that natural barrier, the navy and other emperors' fleets can freely enter and exit Wano Country—this is not a good thing for my territory.

Roy shook his head: "There's no need for that."

He raised his hands, palms down, aiming them at the dark surface of the water beneath his feet.

His psychic power surged forth from his body, penetrating the water's surface with remarkable precision and extending into the depths of the ocean.

This time, the amount of psychic power output was greater than ever before, and Kaido and King, who were standing next to him, could clearly sense that invisible power was rapidly expanding.

The water surface began to tremble.

At first, there were only fine ripples, then violent splashes, and finally the entire underground lake boiled.

White waves burst open on the water's surface, as if some enormous creature was awakening from the depths.

Roy closed his eyes and enveloped every inch of the warship that had been sleeping for eight hundred years deep in the water with his mental power.

Then a thought struck him.

The water surface suddenly exploded.

A huge black shadow slowly rose from the bottom of the water.

The bow was the first part to emerge from the water.

It was a massive, breathtaking metal ram, shaped like a dragon's head, with a dark red pearl held in its open mouth.

The surface of the ram showed no signs of rust and gleamed with a cold metallic luster under the glow of the pale blue fluorescent light.

Then there's the hull.

The black metal hull emerged from the water inch by inch, and seawater poured down from the deck like countless waterfalls cascading down at the same time.

The ship's sides were densely packed with three layers of cannons, each of which was larger than Kaido's head.

Behind the cannon muzzle, one can vaguely see a complex mechanical structure. It has never seen sunlight in eight hundred years, yet it still maintains its complete form.

The ship rose higher and higher until it was completely above the water and came to a steady stop at the edge of the platform.

Looking up from the platform, the warship resembles a black fortress floating on the water.

Even though Roy had previously used his telekinesis to probe Hades' size, he still couldn't help but gasp when he saw it with his own eyes.

too big.

It's really too big.

The Ark Maxims, placed next to this Pluto ship, would look like a small sampan.

The entire warship is hundreds of meters long from bow to stern, and its deck is wide enough to accommodate tens of thousands of people for drills at the same time.

The widest beam on the hull is so thick that three people holding hands cannot wrap their arms around it.

Three main masts stand on the deck, their height reaching straight up to the fluorescent minerals at the top of the rock face.

Although the sails hadn't been used for eight hundred years, the canvas was still neatly tucked under the mast, and the material didn't look like ordinary cloth, but rather had a faint metallic sheen.

What's most eye-catching is the main cannon at the bow.

The cannon's caliber was ridiculously large; a small sailboat could be shoved right into its muzzle.

The cannon was entirely black, with its surface covered in dense patterns. These patterns did not appear to be mere decorations, but rather resembled variations of some kind of ancient script.

The structure connecting the gun mount and the deck is extremely complex, with gears, levers, and buffer devices layered one on top of another, making it look like the gaping mouth of a sleeping steel behemoth.

Kaido looked up at the main cannon, his mouth agape wide enough to fit a gourd of wine.

"Is that a cannon?"

He pointed his thick finger at the muzzle of the main cannon.

"With this caliber—how big must the shells be?"

"I suspect it doesn't fire any live ammunition at all."

Roy walked to the bottom of the main gun and reached out to touch the ancient inscriptions on the surface of the barrel.

"These patterns and the historical text of Skypiea use the same writing system."

Look here—

He pointed to a regular groove around the base of the cannon barrel.

"This structure is not for loading live ammunition."

It's more like some kind of energy transfer device.

If my judgment is correct, this main gun is not firing cannonballs, but some kind of energy attack.

The power—destroying an island with a single shot—is probably not an exaggeration.

Kaido's gasp echoed through the empty underground space.

He patted Roy on the shoulder, repeating the same phrases over and over: "Good stuff," "Worth it," "You made a killing."

Roy slapped Kaido's hand away and jumped onto the deck of Pluton first.

The deck feels completely different to the touch compared to ordinary wood.

The deck material of this warship is not wood, but a composite material made of some kind of metal and wood fiber.

Its surface has a fine texture, which makes it extremely slip-resistant, and it has not rotted at all in the past eight hundred years.

Jin jumped onto the deck, crouched down, and tapped the deck surface with his fingers, his brows furrowing slightly behind his glasses.

He had never seen this material before, nor did it resemble any known shipbuilding technology.

Kaido was the last to jump up.

His weight, combined with the impact of his landing, kept the deck completely still.

Given Kaido's size and weight, he could easily stomp through the deck of an ordinary warship.

But Pluto's deck didn't even tremble, its sturdiness was terrifying.

The three walked along the deck toward the cabin.

The secondary guns on both sides of the deck were lined up one after another, so densely packed that it would take quite a while just to count how many guns there were.

Each secondary gun has a control switch on its mount similar to that of the main gun, and its operation doesn't seem complicated.

After crossing the wide deck, the three arrived at the cabin entrance.

A huge metal door blocked their way.

The gate was about five meters high and wide enough for three carriages to drive in side by side. It was made entirely of the same black metal as the ship's hull.

There were no handles or keyholes on the door, only an ancient character engraved in the center that matched the pattern on the main cannon.

Roy reached out his hand, about to push the door open.

A mechanical sound suddenly rang out.

The sound wasn't loud, but it suddenly exploded in the underground shipyard that had been silent for eight hundred years, making it sound particularly jarring.

"Unauthorized personnel have entered the premises. Unauthorized personnel, please leave immediately."

Kaido and King stopped in their tracks at the same time.

Roy withdrew his hand, a hint of surprise flashing in his eyes. Eight hundred years had passed, and this warship was still able to passively defend itself?

The announcement was repeated twice more, for a total of three times.

Then, tiny points of light lit up on the walls on either side of the metal gate.

The dots of light were neatly arranged on the wall, like some kind of small launch port.

Each point of light was rapidly charging, changing from dark red to bright red, and then from bright red to dazzling incandescent white.

Kizaru's laser.

The thought flashed through Roy's mind.
