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

Zoro leaned against the mast, three swords hanging at his waist. When he heard the word "samurai," his ears twitched slightly.

But he didn't open his eyes; only a barely perceptible smile appeared at the corner of his mouth.

"The currents here are too turbulent; it's impossible to navigate normally."

Nami bit her lip, carefully sensing the surrounding climate, trying to analyze the patterns of the ocean currents.

But each analysis result was overturned by the next wave of even more chaotic ocean currents.

Kin'emon stepped out of the cabin, still wearing the kimono he hadn't changed since returning from Zou Island.

He walked to the ship's side, looking at the huge shadows constantly leaping out of the water, a complex emotion flashing in his eyes.

"We can make use of these koi fish."

"A koi fish?" Luffy jumped to Kin'emon's side and followed his gaze.

On the sea, groups of giant koi are swimming upstream.

Each one was as big as the Sun Lion, its scales gleaming with a pale golden light in the thick fog.

They leap from the depths of the sea, arc through the air, and then crash back into the ocean, splashing white sprays tens of meters high.

"These are giant koi carp unique to Wano Country. Every year at this time, they swim upstream to the inland rivers of Wano Country."

Kin'emon pointed to the giant fish that were constantly leaping out of the water.

"If you grab them, you can go up the waterfall with the ocean current."

"Catching fish?"

Luffy's eyes lit up immediately.

"That's easy!"

Luffy's arms suddenly stretched out, one in each hand, and he accurately grabbed the dorsal fins of two giant koi that had just leaped out of the water.

Its legs stretched out and tightly wrapped around the lion's head at the bow of the ship.

The Sun Lion, being dragged along by the koi, began to move forward at high speed. The ship rocked violently on the sea surface more violently than before, but its direction became clearer.

Directly ahead, there's a waterfall hidden deep in the fog.

"Hold on tight!" Nami shouted to the others on the deck as she clung to the mast.

Franky grabbed the still-dazed Chopper, while Robin used her Flower-Flower Fruit powers to conjure dozens of arms on the deck to grab the ship's gunwale.

Brook plunged the Soul-Slaying Sword into the crack in the deck and gripped it tightly, while Zoro remained leaning against the mast, motionless.

The waterfall is getting closer.

Luffy grabbed the dorsal fins of two giant koi, his rubber arms stretching longer and longer as the koi struggled, while he let out a loud "Wahahaha" laugh.

The thick fog thinned at the edge of the waterfall, and sunlight streamed down from above. Guided by koi carp, the Sunshine Boat swam upstream against the current.

"arrive--!!!"

Luffy released his grip, and the Sun Lion, using its last momentum, surged to the top of the waterfall, flew in the air for a full two seconds, and then crashed heavily onto a patch of water.

Guided by Kin'emon, the group arrived at a secluded port and stopped.

Luffy was the first to jump off the ship, his bare feet touching the sand, hands on his hips, taking a deep breath.

"The air of Wano Country—!"

Everyone was waiting for him to finish his sentence.

"It's no different from other places."

Luffy scratched his head and said with a serious expression.

Zoro disembarked from the ship, carrying his sword, and glanced around at the surrounding scenery.

Near the beach is a desolate sandy beach with coarse sand that is a bit rough on the feet.

In the distance, several factories emitting white smoke could be vaguely seen. The smoke coming out of the chimneys was not black, but a pale grayish-white, almost invisible against the backdrop of the sky.

"Is this the country ruled by Kaido?"

Sanji lit a cigarette, squinted at the factories in the distance, and

"It looks better than I expected."

Kin'emon's expression was somewhat complicated.

His gaze shifted from the factory to the fields, and from the fields to the figures working there.

Then, from that sky, so different from the one in my memory, I moved towards the distant, faintly visible, skull-shaped island.

Robin crouched down and drew a simple map on the beach with his finger.

"The terrain of Wano Country is divided into several regions—Kuri, Udon, Flower Capital, Nozomi, and Hakumai."

According to Kin'emon's earlier description, we should be on the beach in Kuri now.

"Kuri."

Kin'emon clenched his fists, his nails digging into his palms. A complex expression appeared on his weathered face—a mixture of nostalgia, anger, resentment, and a longing suppressed for twenty years.

"The place that Lord Oden ruled back then."

Luffy dusted off the sand and walked over to Kin'emon.

"Kin'emon, that guy named Kaido—he's pretty strong, isn't he?"

"Extremely strong."

Kin'emon's voice was hoarse, each word sounding as if it were carved from his bones.

"He is one of the strongest people on this sea."

Lord Oden also... was defeated by him back then.

Luffy remained silent for a moment.

Just when everyone thought he would say "So what?", he simply grinned.

"Then we should definitely beat him to a pulp."

Let's go back to ten days ago.

Ghost Island, Roy's room.

Luffy's ally, Trafalgar Law, sat opposite Roy, while Kiku leaned back on the armrest of his chair.

His expression remained as calm as ever.

"Roy, you want me to continue my alliance with the Straw Hat Pirates?"

Roy's voice was devoid of emotion, but Roy could read the confusion in his eyes.

"right."

Roy poured Ro a glass of wine; the amber liquid swirled in the glass.

"You and Luffy will challenge Kaido together."

"You want me to confront Kaido head-on?"

Luo picked up the glass but didn't drink it. He simply held it in his hand, feeling the cool temperature of the wine seeping through the glass.

"It's not a challenge, it's a test."

Roy looked at him, his tone serious.

"You've been sailing the high seas for several years now, and the fruits of your labor need stronger opponents to hone them."

Doflamingo was a strong fighter before, but that level of combat might be enough for ordinary strong fighters, but it's not enough for you.

Luo remained silent, waiting for Roy to continue.

"Kaido is one of the strongest warriors on the seas who is currently close to the pinnacle."

His Azure Dragon form, the strength of his three-colored Haki, and decades of accumulated combat experience are things that cannot be caught up with through training.

You have to experience it for yourself to know what the real peak looks like.

Fighting him will allow you to discover your own limits.

Roy picked up his glass and took a sip.

"Furthermore, I will have the Beasts Pirates pretend they don't know you."

"You'll be fighting as an ally of the Straw Hat Pirates, so no one will know about your connection to Honeycomb Island."

Luo remained silent for a long time, watching the wine slowly swirling in the glass.

"OK."

Luo picked up his glass and downed it in one gulp. The wine flowed down his throat, leaving a warm, burning sensation.

"Anyway, I want to see how much of a gap there is between me and the top experts."

He stood up, hoisted the ghostly wailing onto his shoulder, and walked towards the door.

As he reached the door, Roy suddenly called out to him.

"Luo."

Luo stopped and turned his head.

The corridor lights cast half shadow and half light on his face, and his calm eyes flickered slightly in the shadows.

"Don't worry, I'll make sure Kaido goes easy on you. He won't kill you."

A meaningful smile appeared on Roy's lips.

"Thank you very much."
