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

Roy gestured for Barrett to put Yamato down, then walked over and knelt down in front of her.

"Yamato, why did you come all alone? Does Jin know?"

"Brother Jin doesn't know, I snuck out! I heard you guys are really powerful, I wanted to come and see for myself!"

"You're their captain, right? Jack said you're very strong."

"Can you teach me how to defeat my father?"

Looking at Yamato blinking his eyes, Roy gave a wry smile.

"I don't know either, we'll only know after we play it."

"But why did you want to defeat Kaido?"

Roy's question silenced Yamato for a moment.

She lowered her head, her small hands unconsciously gripping the spiked club tightly, her eyes becoming complicated.

"Because...my father..."

Yamato's voice grew softer and softer.

"He's always sabotaging things, always bullying the weak, and forcing me to do things I don't want to do... I don't like that."

"Is this why you want to become stronger?"

"Mmm." Yamato nodded repeatedly.

Roy looked at Yamato, feeling a mix of emotions.

In the original work, it was under these circumstances that Yamato saw Oden dare to rebel against Kaido, and that's when she began to admire Kozuki Oden and identify herself with Oden.

Furthermore, after obtaining Oden's diary, he even wanted to open Wano Country to the world in Oden's will.

And now, the seed of rebellion against Kaido seems to have taken root and sprouted in her heart.

It has to be said that this father and daughter are both stubborn, and Roy has no words to praise Kaido's parenting style.

"All right......"

"Yay! Let's get started." Yamato happily grabbed Roy's hand and started to walk outside.

Caught off guard, Roy nearly stumbled from her pull. After regaining his balance, Roy was astonished.

It's no wonder he has Kaido's bloodline; he possesses considerable power at such a young age. The bloodline of the Oni clan is truly terrifying.

This made Roy increasingly interested in Yamato.

Yamato hasn't met Kozuki Oden yet; in fact, she's the one who came to him of her own accord.

If trained properly, he will become a powerful general in the future.

This might be an opportunity...

Roy looked at the Yamato before him, pondered for a moment, but quickly dismissed the idea.

If we simply kidnap Kaido's daughter, given his personality, he'll definitely go insane, and any further cooperation will be out of the question.

This is not conducive to Roy's next plan; let's take it slow and make contact first.

"What's wrong?"

Seeing that Roy didn't go out with him, Yamato turned his head and asked in confusion.

Roy ruffled the white-haired loli's hair with a hint of annoyance. He really didn't know what kind of guy Kaido was like.

How did you raise such a thick-skinned daughter?

"Yamato,"

Roy straightened the little girl's position.

"Becoming stronger takes time and effort; it's not something that can be done overnight. Besides, you're still young, so you should focus on building a solid foundation first."

"I already have a basic understanding! Brother Jin taught me a lot! But I want to learn even more!"

Yamato raised his spiked club and looked at Barrett.

"That big guy is amazing! He knocked Jack out with one punch! I want to learn that kind of boxing!"

Upon hearing the term "uncle," Barrett's forehead veins bulged: "I'm only 17! Call me brother!"

"Okay, Uncle!" Yamato readily agreed.

Barrett: "..."

Everyone couldn't help but laugh.

Roy chuckled, "Yamato, if you want to learn, you can come to the training ground every morning, and I'll guide you through some basics."

"Really?!" Yamato's eyes lit up. "That's great! Thank you!"

She excitedly spun around the room, when suddenly she saw the unfinished roast meat on the table, and her stomach growled.

Stella smiled and handed her a new plate of roast meat:

"Eat up, you'll have the energy to train."

"Thank you, sister!" Yamato took the food and began to eat heartily.

Everyone smiled as they watched her wolf down her food.

This daughter of Kaido is not quite what I imagined.

After breakfast, Roy brought Yamato to the training ground.

At the training ground, Jack and the others were already doing their morning exercises. They were all taken aback when they saw Yamato coming over with Roy.

"Miss Yamato?" Junti looked at Yamato with Roy. "What's wrong...?"

"I've come to cultivate with Brother Roy!"

Yamato announced loudly, waving his spiked club.

Jack and the others looked at each other in bewilderment.

Didn't Brother Jin say not to mess with the Roy Pirates? What's wrong with Miss Yamato...?

But considering that Kaido was already on his way back, and that King seemed to have reached some kind of agreement with Roy, they felt relieved.

Roy looked at the four children in the room. Besides Jack, whom he had met yesterday,

The remaining ones should be three of the future Flying Six. To be honest, they are all guys with good potential.

"Let's begin."

Yamato tugged at Larroy's sleeve.

"Don't rush," Roy smiled, crouched down, and touched Yamato's forehead with his finger.

A training method containing the Six Styles of the Navy entered Yamato's mind.

"What are you doing?!"

The four members of the Beasts Pirates exclaimed in surprise upon seeing Roy's strange actions, and moved swiftly to stop him.

Roy withdrew his finger, turned to the side, and pointed his index finger at the four of them.

"Command - Set!"

Jack, Maria, Rumti, and Page Van were immediately frozen in place, unable to move.

Jack, the oldest among them, was even more horrified. Roy's incomprehensible attack reminded him of the irresistible pressure he felt when facing Governor Kaido.

"take it easy."

Roy withdrew his finger, and the four of them immediately regained their mobility.

"I'm just teaching some basic cultivation methods."

Roy looked at Yamato, who had opened his eyes.

"How are you feeling?"

"Wow...that's amazing! I've never seen these techniques before!"

Yamato processed the sudden influx of information into his mind, his eyes gleaming with excitement.

"This is the Navy's Sixth Style," Roy explained.

"Advanced physical skills of the World Government Navy. While not exactly a top-tier technique, it's very useful for building a solid foundation."

"Great, let's get started now!"

Seeing the happy little girl, Roy smiled and nodded, though he wasn't sure if she understood.

"good!"

"But I must warn you, my training is very tough, and you can quit at any time if you can't keep up."

"I'm not afraid!" Yamato shouted.

"Let's begin then."

Roy spread his arms, and an invisible gravitational field enveloped the area.

The release of mental energy raised the gravity to the limit that everyone could adapt to, not even sparing Jack and his group of four.

As soon as Roy finished speaking, Jack and the others felt a sudden heaviness in their bodies, as if a mountain had been placed on them.

"What...what is this?!" Runti gritted her teeth, struggling against the weight on her body.

Yamato also felt a sense of heaviness, but her eyes were full of excitement: "This is so interesting! Brother Roy, will this make me stronger?"

"certainly."

Roy nodded.

"Training in a gravity environment can greatly improve physical fitness, but it is important to proceed gradually and not rush it."

Jack and his three companions exchanged glances, noticing that the Roy Pirates had already begun training on their own initiative.

He understood immediately. No wonder the Roy Pirates were so strong; they had been training in this kind of environment all along.

Immediately, they stopped hesitating and began their physical training.

Throughout the training field, painful groans and heavy breathing echoed.
