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

Outside the glass is an underwater world.

The ruins of Wano Country from eight hundred years ago lie quietly on the seabed.

The ancient wooden buildings stand in rows, and the roof tiles still look the same as they did back then.

The direction of the streets is clearly discernible, and one can even see the differences in layout between the townspeople's quarters and the samurai residential areas from back then.

A five-story pagoda stands askew in the center of the complex, its bronze bell swaying gently in the seawater, as if still ringing out eight hundred years ago.

Schools of sea fish swam in the street, swimming in through the windows of this house and out through the roof of that house.

Seaweed climbed all over the walls, turning the entire site a deep green.

An entire ancient city was sealed on the seabed, sleeping for eight hundred years.

Jin stood in front of the glass, his sunglasses reflecting the dim light and shadow of the underwater ruins.

He didn't say anything, but from his slightly forward-leaning posture, it was clear that this usually calm to the point of being cold was also shocked by the scene before him.

"This is the land of Wano from eight hundred years ago."

Roy's voice wasn't loud, but it was clearly audible in the enclosed passageway.

"At that time, Wano Country was built on this seabed plain."

Later, in order to hide the Hades warship, people with certain abilities erected a huge encirclement wall around the island.

The rainwater couldn't drain away, and year after year, the seawater accumulated deeper and deeper, eventually submerging the entire city.

The people of Wano had no choice but to retreat to Mount Fuji and rebuild a new Wano Country inside the surrounding walls.

Roy paused, his gaze passing through the glass and landing on the underwater ruins.

"Kozuki Oden always wanted to open the country, probably because he wanted to break down that encirclement barrier and allow the people of Wano Country to go out to sea freely."

Unfortunately, he never achieved it before he died.

Kaido's voice came from outside the passage, deep and muffled.

"What are you two looking at in there! Come out now!"

Roy and Jhin exchanged a glance, then turned and walked out of the passage.

Kaido crouched in the passageway, his neck stretched out, his rugged face filled with impatience and curiosity.

He was too big to squeeze through the passageway and could only stand outside and stare blankly.

"What's inside?"

"A relic on the seabed."

"The land of Wano from eight hundred years ago is right below there."

Kaido paused for a moment, then grinned.

"Hehehehe!"

"No wonder Kozuki Oden was always thinking about opening the country—it turns out his family was flooded!"

Roy didn't respond to that, but simply patted Kaido's arm.

"Keep going down, Pluto is still deeper inside."

The three continued down the stairs.

The further down you go, the more humid the air becomes.

Water droplets began to seep from the stone wall, and the steps underfoot became slippery.

The beam of the searchlight shone ahead, and the outline of the end of the stairs could be vaguely seen.

Finally, the stairs came to an end.

A massive stone gate blocked the way for the three of them.

The stone gate is about seven or eight meters high, and its surface is covered with cloud-patterned reliefs in the style of Wano Country.

On either side of the door frame stands a stone-carved komainu (guardian dog), its posture menacing, as if warning intruders not to go any further.

Roy reached out and pushed against the stone door.

The stone gate was unlocked, but extremely heavy.

Roy used his telekinetic power to push the stone door inward.

Behind the door is a huge underground platform.

The platform is not large, only a few dozen feet in diameter. The entire platform is suspended in the center of the underground lake, surrounded by dark seawater.

The platform has a low stone railing at its edge, beyond which lies the bottomless water.

The rock walls overhead were inlaid with unknown minerals, which emitted a faint blue glow, illuminating the entire space in a half-light, half-dark manner.

In the very center of the platform stands a huge red stone tablet.

The stone tablet is about three zhang tall. Its surface should have been smooth, but it is now covered with moss and barnacles.

Eight hundred years of damp erosion have left mottled marks on the surface of the stone tablet, but the ancient characters carved on the tablet are still clearly legible.

Historical text.

Kaido's eyes widened the moment he saw the red stone tablet.

"Hehehehe!"

"I never expected there to be another one here! I searched Wano Country for so many years and couldn't find it, only to find it hidden here!"

Kaido strode forward, extended his large, fan-like hand, and patted the stone tablet, causing the moss on it to fall off in a flurry.

Roy walked up to the stone tablet and carefully examined the inscription.

Including this one, he now knows the whereabouts of three pieces of red historical texts.

The Fishman Island map has already been copied, the Wano Country map is right in front of us, and there's another one in Zou.

As for the last piece—he guessed it was most likely in Elbaf, the land of giants.

Roy took out paper and ink for rubbing from his storage bag and began to make rubbings of the text on the stone tablet.

Jin stood at the edge of the platform, looking down at the dark water below.

His Observation Haki detected something below the surface of the water, but the water was too deep for him to see clearly what it was.

After Kaido and Roy finished making the copy, Kaido finally couldn't help but ask:

"Roy, you said Hades is here, but this place is only so big—"

Where is that warship?

Roy carefully put the rubbing back into his storage bag, dusted off the ink on his hands, and walked to the edge of the platform.

"Don't rush."

Roy crouched down, placing his right hand on the stone railing at the edge of the platform.

His mental energy surged from his palm, like an invisible giant net, spreading downwards towards the water's surface.

The water surface remained calm, but both Kaido and King could sense something being disturbed underwater.

Ripples spread outward from the edge of the platform, growing larger and faster.

A moment later, Roy opened his eyes, a smile playing on his lips.

"Found it."

The moment Roy uttered those three words, "Found it," Kaido exploded like a powder keg.

A slap landed on Roy's back with such force that two of the stone slabs beneath Roy's feet cracked.

"Hehehehe!"

I knew you were reliable!

"Forming an alliance with you is the best decision I've ever made in my life!"

Roy stumbled forward after being slapped, then turned and glared at him.

Kaido didn't care at all; his rugged face broke into a wide grin, and his large, round eyes were filled with barely suppressed excitement.

Jin stood to the side without saying a word, but the way he raised his hand to push up his sunglasses revealed that he was not at peace with himself.

Having followed Kaido for so many years, he had rarely seen Kaido so happy.

"Where exactly is Hades? How do we get it up here?" Kaido asked impatiently.

Roy stretched his shoulder, which had been patted so hard, walked to the edge of the platform, and looked down at the dark water below.

"It's right down here."

It's at a depth of about several hundred meters.

The people of ancient Wano Country sank it in an underground dock.

"A few hundred meters? That's easy!"

Kaido rolled up his sleeves, revealing forearms thicker than an adult's thigh.

"I'll just dive down and carry it back up!"

Are you sure?
