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

Traveling to the present day,

He relied on his foresight, his own efforts, and the support of his partners.

It has come a long way to become a dominant force in the new world.

But deep down, a lingering worry remained.

The true monsters of this world, those beings possessing terrifying innate talents...

Characters like Kaido, Charlotte Linlin, and even Luffy in the future... their starting point is, to some extent, the end point that many people strive for their entire lives.

Although the Nen-Nen Fruit has immense potential, and swordsmanship and Haki are steadily improving, if the "innate physical constitution" could be completed...

Roy closed his eyes, quickly weighing the options in his mind.

Risk? The report indicates it has dropped to extremely low levels.

The cost? Aside from resource investment and a period of adaptation, it's almost negligible.

Benefits? Perhaps a comprehensive leap in physical fitness and an enhancement of potential.

More importantly, as the captain and the leader of the group, he had to be the first to try.

This is not only to verify the reliability of the technology, but also to show our partners our stance.

He shared the risks with them and embraced the transformation together.

The decision was made in a matter of seconds.

Roy picked up the encrypted Den Den Mushi and dialed directly into Dr. Gracia's lab's dedicated line.

"Doctor, I've finished reading the report."

Roy got straight to the point.

"Are you sure the technology is mature enough to conduct experiments for us?"

Dr. Gracia's composed voice came from the other end of the phone.

"Captain Roy, based on all the available data and experimental results, yes."

We have eliminated known risks to the greatest extent possible.

Of course, the human body is a complex system, and the final effects and subtle reactions can only be fully confirmed after practical application.

But I can guarantee that I'm 99% confident in its safety.

"Ninety-nine percent..."

Roy pondered for a moment, his fingers unconsciously tapping on the table.

"That's enough. Doctor, get ready. I've decided to be the first to receive a bloodline transplant."

"Really? That's great!"

Dr. Gracia's voice rose instantly, filled with the excitement of a researcher seeing their findings about to be put into practical application.

"I will immediately begin preparing a dedicated laboratory and your exclusive fusion embryo!"

It is expected that two days will be needed for final compatibility tweaks!

"Okay, at your pace."

Roy paused, then suddenly seemed to remember something.

"By the way, Doctor, regarding this technology... has Kaido informed us of it?"

"not yet."

"As you instructed, the core technical details have been kept strictly confidential."

However, the demon bloodline samples and early experimental subjects provided by Mr. Kaido were indeed invaluable.

Roy nodded.

Kaido... this ally, though unrestrained and ambitious,

However, they did provide considerable support in the early stages of the collaboration.

Without the demon bloodline samples and numerous "volunteers" he provided, Dr. Gracia's research progress could not have been so rapid.

Moreover, this technology, which can fundamentally strengthen power,

If this is kept completely from Kaido, it will inevitably affect or even destroy the alliance between the two sides once it is leaked in the future.

Instead of doing that, it would be better to proactively share some of the results, which would not only strengthen the alliance but also bind Kaido more closely to their cause.

"I understand. Doctor, you go ahead and prepare. I'll contact Kaido."

After ending his call with the professor, Roy thought for a moment, then picked up another strangely shaped Den Den Mushi, resembling a dragon's head.

This is an encrypted line directly connected to Kaido.

"Brubrubru... Brubrubru..."

The call connected, and immediately a deafening cacophony erupted from the other end.

There was wild laughter, clinking glasses, and beast-like roars, with the sound of collapsing buildings seemingly in the background.

"Hehehehe! Roy!"

"Why did you suddenly think of contacting me?"

"Is there some good deal coming up again, or are you in trouble and need my help?"

Kaido's rough and bold voice came through the Den Den Mushi.

Roy was already used to his ally's style and calmly said, "Kaido, there's some news I think I should tell you."

"Oh? What news? Tell me quickly!" Kaido seemed interested, and the background noise quieted down a little.

"Dr. Gracia's bloodline transplantation research is nearing perfection."

Roy got straight to the point.

"The technology is basically mature and can be safely applied to strong individuals like us to significantly enhance their basic physical condition and potential."

The other end of the phone went silent instantly.

Even the background noise seemed to have been muted.

A few seconds later, Kaido's voice rang out again, but this time it was no longer drunk; instead, it was filled with extreme focus and excitement.

"What did you say? The bloodline transplant...it's successful? It's usable?!"

"Yes."

"I just finished reading the final report and have decided to be the first to try it," Roy affirmed.

"Ooh lol lol lol lol!!!"

A deafening burst of laughter erupted once more; even through the Den Den Mushi, Roy could feel the surging power and joy.

"Good! Good! Good! I knew I hadn't misjudged you, Roy kid!"

It wasn't a waste of time to support that PhD! They got it done so quickly!

Kaido's excitement almost overflowed from the Den Den Mushi.

"When does it start? I want a transplant too!"

"The bloodline of the Oni race combined with the advantages of other races..."

"Hehehe, I can't wait to see just how strong I can become!"

"I need two days to prepare. The doctor said that my custom embryo needs to be fine-tuned."

Roy calculated the time,

"If you're coming, it should be able to start in three days."

"Three days? That's too slow! I want to fly there tomorrow... no, right now!" Kaido was impatient.

"Kaido, calm down."

Roy said helplessly,

"Preparation takes time and cannot be rushed."

"Besides, don't you need to make some arrangements on your side? Leaving so suddenly, what about the situation on your territory..."

"Territory? Just leave it to Jhin and Quinn! Those small fry can't cause any trouble!"

Kaido seemed unconcerned, but then something occurred to him.

"By the way, you said you wanted to be the first to try it? Are you confident? Is there any danger?"

"The doctor said he was 99% sure. I believe his judgment."

Roy answered,

"Moreover, I tried it myself to set an example for my partners."

"Hmm...that's bold! I like it!"

Kaido gave a thumbs-up.

"Then it's settled!"

"Three days from now, I'll bring Jhin and Quinn over there!"

They both need some improvement!

Especially Jhin, with the blood of the Lunar race and new power...

Mmm, just thinking about it makes me excited!

"Sure. I'll make the arrangements." Roy agreed.

"Alright! See you in three days! Have the Doctor prepare the best embryos! I want the strongest combination!"

Kaido laughed and hung up the phone.

After putting down the Den Den Mushi, Roy walked to the window and gazed at the setting sun, which was already halfway down the horizon, his eyes deep and thoughtful.

Three days later, Beehive Island will undergo a far-reaching "evolution".

His alliance with Kaido may thus enter a new phase.

Next, he needs to tell his friends about it.
