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

The next two days,

The energetic Yamato would appear in Roy and the others' room whenever he had a spare moment.

She was either asking about their adventures or pestering Roy to teach her.

Jin, who was in charge of affairs on Ghost Island, watched as Roy and the others did nothing but cultivate.

This allowed Yamato and Roy to continue their contact.

On the morning of the third day, Roy, who was sitting cross-legged on the training field, suddenly changed his expression, and the steam swirling around him gradually dissipated.

Roy stood up and looked up at the sky in the distance over Ghost Island.

"What's wrong, Roy?" Barrett asked curiously, noticing Roy's strange behavior.

"Kaido is back."

As Roy finished speaking, a dragon's roar echoed across the sky above Ghost Island!

Everyone looked up and saw a colossal azure dragon, nearly a thousand meters long, tearing through the clouds.

It swooped down.

Inside Onigashima, King, who was discussing the mission with Queen, was the first to sense Kaido's presence.

He exchanged a glance with Quinn, spread his wings, and his tall figure flew out from the skull's eye on Ghost Island.

Kaido's blue dragon circled once in the air, then suddenly swooped down, transforming into human form as it approached the ground, crashing down and kicking up a cloud of dust.

Its massive body, over seven meters tall, had a bare upper body covered in scars, a purple belt around its waist, and a huge spiked club in its hand.

"Jin!" Kaido's voice, like thunder, echoed throughout Onigashima.

"Where are those kids?!"

"Boss Kaido, they're training in the training grounds, we..."

"Hmph!" Kaido snorted coldly, and before King could finish speaking, he strode towards the training ground.

In the training ground, Roy and his group had stopped their training and gathered together.

Roy smiled as he watched Kaido approach step by step.

"Kaido of the Beasts! I've long admired your name!"

Kaido stopped ten meters in front of Roy, and the pirates behind him gradually gathered, with King and Queen standing on either side.

The subordinates gradually gathered together, and even Jack and the others who had been training together for the past few days saw that things were not going well and ran to Kaido's back.

The two groups of people were clearly separated.

Yamato was left staring angrily at Kaido.

Kaido's gaze slowly swept over Roy and the others, finally settling on Yamato.

"Yamato, come here!"

"I don't!"

Yamato, holding "A-Jian" in his hand, stared defiantly at Kaido.

"Roy and the others are my friends! And they've been teaching me cultivation these past few days. I won't allow you to hurt them!"

Yamato's words surprised the members of both pirate crews.

Kaido stared intently at Yamato, then suddenly threw his head back and burst into laughter.

"Hehehehe... Interesting! So interesting!"

"Yamato, are you going to disobey my orders?!"

Kaido's laughter abruptly stopped, and his massive body exuded a terrifying pressure, pressing directly towards Yamato.

The air in the training field seemed to freeze, and even Jhin and Quinn subconsciously stepped back.

Yamato gritted his teeth, his face pale, but he still stood stubbornly in place, his hands tightly gripping the spiked club "Ken".

"I...I'm just stating the facts!"

Yamato's voice trembled slightly.

"Roy and his brothers are good people!"

They taught me cultivation, told me adventure stories, and never harmed me! Father, you mustn't hurt them!

These words touched Roy deeply.

Unexpectedly, in just a few days, Yamato developed such a deep trust in them.

Seeing the farce unfolding before him, Roy stepped forward and used Yamato to block Kaido's oppressive aura.

"Alright! Kaido, stop with your pointless probing!" Roy said calmly, looking directly at Kaido.

"We've come here to discuss a collaboration with your Beasts Pirates."

"cooperate?"

Kaido grinned, revealing his gleaming white teeth.

"You bunch of brats, you think you're worthy of discussing cooperation with me?"

"They trespassed on my territory and even dared to challenge me..."

Before he could finish speaking, Kaido suddenly moved!

The massive spiked club "Eight Precepts" came crashing down on Roy's head with a terrifying whooshing sound!

This attack was simple and direct, but its power was so terrifying that it compressed the air into a shockwave visible to the naked eye!

"If you want to cooperate, then let us show you whether we're qualified!"

Barrett roared and instantly entered Demon Mode. His right arm swelled several times its normal size, covered in black and red Armament Haki, and he punched the spiked club!

"Thump—!!!"

The fists clashed, producing a deafening roar!

The terrifying shockwave spread outwards from the point of impact, shattering all the doors and windows of the west wing instantly, and cracking the stone slabs on the ground inch by inch!

The ground beneath Barrett's feet caved in, creating a deep crater, but he withstood the blow, his feet firmly planted on the ground, without taking a single step back!

"It's you again!"

This clash reminded Kaido of his brief encounter with Bullet in the Sabaody Archipelago.

"hey-hey!"

"It's not over yet!"

Barrett grinned dramatically, and his left fist followed closely, slamming towards Kaido's abdomen!

"Bang!"

With a muffled thud, Kaido's massive body retreated rapidly, sliding for more than ten meters, his legs carving two furrows in the ground, but he quickly regained his footing.

He patted off imaginary dust from his body.

"Kid, not bad strength!"

"The same to you!"

Seeing Kaido suddenly attack without warning, Roy understood that if he wanted to cooperate with Kaido, a fight was inevitable.

"Why!"

Roy sighed inwardly, his figure flashing as he stood between the two, interrupting the impending second round.

"Kaido, how about we fight somewhere else?"

"I imagine you wouldn't want to see your base of operations completely destroyed!"

Roy pointed around; the training ground was cracked with countless fissures from the collision, and distant buildings swayed precariously in the aftershocks.

Kaido looked around, grinned,

"Hehehehe... You're right! I don't want to tear my house down!"

He put away his spiked club, his body suddenly expanded, and he transformed once again into a thousand-meter-long azure dragon, soaring into the sky.

"Roy, 'Heavenly Path,' if you want to discuss cooperation, then follow me!"

Watching the azure dragon circling in the sky, Roy thought to himself,

"Looks like Kaido isn't just a mindless brute after all!"

"Boss! Do you need us to come with you?" Tesoro asked anxiously as he gathered around.

Roy looked around and finally settled on Barrett, who was brimming with fighting spirit.

"Alright, Tesoro, Stella, you two stay on Onigashima. Protect our companions. This time, Barrett and I will go together."

"All right."

Tesorosdella nodded to indicate that she understood.

After arranging everyone, Roy and Barrett slowly rose into the air, following closely behind.

Yamato, who wanted to go with them, was grabbed by King and thrown back into the Beast Pirates' camp.

"I have high hopes for Ms. Yamato."

King gave an order to the members of the Beast Pirates, spread his wings, and soared into the sky.
