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

"right!"

Roy clenched his fist, and the vortex of black mist suddenly contracted, condensing into a jet-black energy ball in his palm.

"After Teach dies, this fruit will be mine."

Kaido remained silent for a long while.

He had seen countless Devil Fruit users, fought Whitebeard for decades, and risked his life against Roger.

But he had never seen anyone use the abilities of three different Devil Fruits simultaneously—

Moreover, he used each one with such ease.

"Three hearts? Three Devil Fruit abilities?" Kaido's voice was hoarse and deep.

"It's not just me."

Roy gestured with his chin toward Barrett.

Barrett had been holding back for a long time, and let out a deafening tiger roar, fully unleashing his white tiger form.

The white tiger stripes throbbed violently beneath his skin, and his body was surrounded by awakened flames and black-red lightning.

"Combined!"

The rock strata beneath his feet were drawn by a purple energy, and countless rock fragments transformed into a purple torrent that surged toward Barrett.

In just a few breaths, Barrett's body had swelled to an astonishing size—

A giant white tiger Gundam made of rock and steel.

Then Barrett took a deep breath and activated the power of the Momo-Momo Fruit.

"Momo - 100x Increase!"

The already enormous beast expanded rapidly under the amplification of the Momo Fruit, growing to a terrifying size of tens of thousands of meters in just a few breaths.

The tiger's claws blotted out the sky, and with each breath, they stirred up a hurricane.

The training ground was completely shrouded in the shadow of this behemoth, blocking out even the sunlight.

The three calamities behind Kaido fell silent.

Quinn dropped the cigar he was holding onto the ground without even noticing.

Jack clenched his fists, his palms sweating profusely.

Although Jin's face remained expressionless, his hands, which were always as steady as a mountain, unconsciously tightened their grip on the hilt of his sword.

Katakuri's pupils contracted violently.

His Observation Haki allows him to foresee the short-term future—if this behemoth attacks him, he can withstand a maximum of three moves.

"Hehehehe—"

After a few seconds of stunned silence, Kaido suddenly burst into laughter, the sound so loud it shook the protective walls at the edge of the training ground.

Roy!

You actually managed to do it!

Multiple Devil Fruit abilities!

Three kinds of fruit!

You actually managed to do it!

He grabbed Roy's shoulder in excitement, his rugged face beaming with barely suppressed elation.

"Tell me how you did it!"

What kind of technology is this?

"Can you get me one too?!"

Roy was so struck on the shoulder by the pat that he almost staggered.

Kaido's grip strength is no joke; even Roy in his current state would find it difficult to withstand being held like that.

He pushed Kaido's hand away and rubbed his shoulder, which had gone numb from being patted:

"Calm down. This technology isn't something you can just pass on to anyone."

Kaido's excitement quickly cooled, replaced by an unusual seriousness.

He glanced around, his gaze sweeping over the core members of Hive Island at the edge of the training ground, then said in a deep voice,

"I know what's important and what's not."

If this technology were to get out, world governments would go crazy.

The Five Elders will destroy it at all costs.

"That's why I want you to keep this a secret."

Roy's expression also turned serious.

"This technology is currently only used within Beehive Island."

Apart from us, no one else knows anything about it.

Kaido raised his right hand without hesitation:

"I swear on my honor as Kaido of the Beasts, this matter will never leave my mouth."

I swear on my life.

Jhin, Quinn, and Jack nodded in unison.

Katakuri remained silent for a moment, then nodded slightly.

"it is good."

Roy's expression relaxed.

"Since that's the case, I won't hide anything from you."

The multi-fruit transplantation technology on Beehive Island is available to you and your core staff.

Kaido's eyes shone like two light bulbs: "What are the conditions?"

"No conditions."

Roy said this in a very casual tone, as if it were just a casual remark.

"You and I have been allies for twenty years. And we share the same goal. Twenty years ago, you dared to bet on me."

This friendship is more valuable than any other condition.

The training ground fell silent for a moment.

Kaido looked at Roy, remained silent for about three seconds, and then burst into laughter.

But the laughter lacked its usual arrogance and swagger; instead, it conveyed a rare sense of unbridled joy.

The exhilaration of being trusted, respected, and treated as a true ally.

"terrific."

Kai patted Roy's shoulder hard, but this time the force was noticeably lighter.

"Roy, I've never admired many people in my life. Whitebeard is one, Roger is another."

You're the third one.

Barrett scoffed to himself as the White Tiger Gundam slowly disintegrated, its inorganic contents cascading down and piling back up at the edge of the training field.

The demonstration of capabilities is complete.

Roy turned and called out towards the entrance of the training field.

"Stella! Notify Dr. Gracia to come over."

Gracia arrived quickly.

He briefly explained the precautions for the upcoming transplant experiment to Kaido and the others.

He then led Kaido and the others to the laboratory to collect experimental samples in preparation for the subsequent transplantation.

With the preliminary preparations complete, Roy called Kaido and King to his office alone.

Kaido entered without any ceremony, plopping down on the sofa and making Roy's single sofa creak loudly.

"Is there something you can't say over there?" Kaido asked.

Roy walked to the table and spread out the map of Warhead Island that he had drawn earlier:

"We're leaving for Warhead Island tomorrow to pick up Vegapunk. Do you two want to come along?"

Kaido frowned:

Vegapunk?

That scientist from the World Government?

You managed to win him over?

"Um!"

"He's already packing his bags."

Roy pointed to the location of Warhead Island on the map.

"But there are over a hundred CP members on the island, and Admiral Kizaru is personally overseeing things."

Want to go have some fun together?

Kaido grinned:

"I'm most willing to fight."

but--"

"Roy, what do you plan to have Vegapunk do after you bring him back?"

Just so I can help you come up with a few inventions?

"The first thing I'll do is replicate your Azure Dragon Fruit."

Kaido was stunned for a moment: "Replicate my Devil Fruit?"

"right."

Roy took the pink dragon fruit out of his storage bag and placed it on the table.

"This is a replica of Vegapunk's previous fruit, and its ability is almost identical to your Azure Dragon Fruit."

He has mastered the replication technology; with just your blood sample, he can mass-produce replicas of the Azure Dragon Fruit.

Kaido stared at the pink fruit for a long time, his breathing gradually becoming heavier:

"Mass re-production? You mean—"

"Your Three Disasters, the Flying Six, and even Katakuri and the others can all obtain another Azure Dragon Fruit through multiple Devil Fruit transplants."

Roy put it very bluntly.

"At that time, every member of the Beasts Pirates will have a Mythical Zoan."

Your dream of building the "strongest Zoan-type army" will no longer be a dream.

Kaido suddenly stood up, his eyes burning with an almost fanatical light:

"They all possess Lao Tzu's Azure Dragon Fruit?"

"As long as you're willing."
