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

"Let's stop the ship here."

Roy ordered the Ark Proverb and the speedboat to stop on the sea not far from the island.

From this distance, one can clearly see lightning striking the sea surface, creating streaks of electric shock.

Activate the defensive mode of the "Proverb" and connect it to Kaido's ship.

The two ships were steadily moored on the turbulent sea.

"Everyone, prepare to log in!"

Roy was the first to float up, his mental energy enveloping his companions on the Proverb, and they flew towards the island.

Kaido laughed and transformed into a blue dragon, grabbing several young people on the speedboat with his dragon claws and following closely behind.

Two groups of people landed one after the other on the rocks outside Thor Island.

"Crackling sound—!"

The moment their feet touched the ground, tiny arcs of electricity shot out from the rocks, sending a shiver through everyone.

"Wow!"

Savi let out a strange cry and almost jumped up.

Enel and Pea also grinned.

Moria's massive body trembled slightly, his Shadow-Shadow Fruit powers being significantly suppressed in this environment.

Vera's face turned pale, but she gritted her teeth and stood firm.

Of the group, only Tesoro opened his arms wide, feeling the raging lightning energy in the air.

"Hahaha..."

"I'm finally back!"

On the Beasts Pirates' side, Jack grunted, but managed to hold on.

Runti and her brother Paget supported each other, while Maria gracefully adjusted her posture.

But her slightly trembling calves betrayed her.

Yamato adapted surprisingly quickly, only frowning slightly before curiously looking around.

"Hehehe! This is a really nice place!"

Kaido reverted to human form and landed, feeling the violent lightning energy in the air, his eyes filled with excitement.

"In this kind of environment, my physical body should also be tempered!"

The flames behind Jin rose slightly, seemingly absorbing free-floating ions in the air.

"The lightning power here... is very pure."

Roy looked around at everyone and began assigning tasks:

"Everyone, first get used to the outer area."

"I will also divide the island into suitable gravity zones according to the intensity of the lightning."

"Each of you should find a suitable area to cultivate in, and don't overexert yourselves!"

"Stella, Enel, Pea, Charon, Moria, and Vera, your primary objective should be to master the restoration of life."

"Savi and Tezolo, you should not slacken your training progress in returning life."

Roy gave the two of them a subtle look.

Savi and Tezzolo nodded to indicate that they understood.

As for Barrett and Hawkeye, given their talents, mastering Life Return shouldn't be too difficult for them.

Kaido and the others looked puzzled as to Roy gave them his instructions.

In the eyes of Kaido and King, returning life was nothing more than a trivial skill.

I really don't understand why Roy wanted his crew to learn this skill first.

Roy glanced at the puzzled Kaido and the others, but showed no intention of explaining, even though the two sides had formed an alliance.

But it's best to prioritize providing the best resources to one's own people, since who knows when the alliance might break down?

Always having a backup plan is the safest approach.

Looking at Jack, Maria, Ulti, Page One, and others from Kaido's camp,

After a moment's thought, Roy decided to teach the group some of the Six Styles and the two-color Haki techniques.

After all, he had promised to help Kaido improve the strength of his subordinates, so it wouldn't be right to do nothing.

Thinking of this, Roy waved to the four of them.

"Jack, Maria, Rumti, Page One, come here. I will teach you some cultivation methods."

The four of them were delighted to hear this. They still vividly remembered the scene when Roy taught Yamato the training method at the training ground.

How could they possibly let such a good thing slip by? The group quickly stood in front of Roy, looking at him expectantly.

Roy touched the foreheads of the four men one by one with his fingers, demonstrating the Six Powers of the Navy and the training methods for dual-color Haki, following the flow of their spiritual energy.

It entered the minds of several people.

Kaido looked at the four people who had stopped standing there with a puzzled expression, then turned to look at King beside him.

"Jin, what are they doing?"

"I'm not entirely sure either, but that's how Yamato was taught training techniques by Roy back then."

"Did Yamato learn those strange martial arts techniques in the same way?"

Kaido narrowed his eyes, watching his four young subordinates remain motionless.

He could vaguely sense a faint energy fluctuation emanating from Roy's fingertips, but he couldn't quite place what it was.

Even with his Observation Haki, he couldn't fully capture it clearly.

"Giggle..."

A glint of light flashed in Kaido's eyes as he murmured to himself.

"Roy, the 'Heavenly Way', your methods are becoming more and more surprising."

A few seconds later, Jack and the other three opened their eyes one after another, their faces showing a mixture of shock and excitement.

"What...what kind of technique is this?!"

Jack clenched his fists, feeling the unprecedented martial arts techniques in his mind—Shave, Moonwalk, Finger Pistol, Tempest Kick, Iron Body, Paper Drawing. Each move was exquisite, and when combined with the use of domineering energy, they were simply killing moves tailor-made for battle.

Runti even jumped up.

"Sis, I've learned it! Hahaha, these hand-to-hand combat techniques are perfect for my headbutts!"

Page One stood there thoughtfully, his hands unconsciously mimicking the gesture of a finger gun.

Although Maria appeared calm on the surface, the glint in her eyes betrayed her inner excitement.

Roy withdrew his finger and said calmly,

"These are the Navy's advanced physical techniques, the 'Six Styles,' as well as the basic training methods for dual-color Haki. They should be helpful to you Zoan-type Devil Fruit users."

"Navy stuff?"

Kaido raised an eyebrow and grinned.

"Roy, you even managed to get your hands on this? If the Navy found out, they'd be furious."

"It's not a secret."

"With your abilities, it shouldn't be difficult for you to get it."

Roy glanced at Kaido and calmly replied.

"Besides, this is just the basics. The truly powerful are always those who use skills."

Kaido snorted, but did not object.

In his view, power is power, and there is no distinction between good and evil. As long as it makes his subordinates stronger, he doesn't care about their origins.

"Buzz—!"

After imparting the techniques, Roy activated the gravity field.

An invisible force spread out from Roy, enveloping the entire Isle of Thor.

From the outermost layer to the core, gravity increases according to the intensity of the lightning—1-5 times the gravity in the outer layer, 6-10 times the gravity in the middle layer, and 10-20 times the gravity in the inner layer.

As for the edge of the core lightning pool, only Tesoro can stay there for a long time without being affected.

After arranging everything, Roy gave another reminder.

"Alright, now everyone find a suitable area to begin your cultivation."

"Remember, act within your capabilities and don't be reckless. I will divide the island into gravity zones, and you can choose whichever you prefer."
