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

Gracia immediately perked up when he heard Luo say that.

He pulled a folder from under the lab bench and slammed it on the table:

"It's all ready!"

Everything from the culturing process of the cloned heart to the ratio of postoperative anti-rejection drugs is here.

I also specifically noted the special situations that users of the Op-Op Fruit might encounter when using it—

Although I lack practical experience with surgical fruits, based on theoretical calculations,

"Your abilities may encounter problems during organ replacement; a simulation exercise should be conducted beforehand."

As the doctor spoke, he pulled out a fist-sized human model from the drawer. The model had three small hearts of different colors embedded in its chest cavity, which were held together by springs and clips.

He picked up the model and waved it in front of Luo:

"Look at this."

The three hearts are arranged in a triangle in the chest cavity, connected in parallel by the aorta, and each heart beats independently.

The reconstruction of the circulatory system was the most complex part of the entire surgery. I conducted three simulations using the seventh experimental subject before finding the optimal vascular layout.

If you were to operate it, you should be able to shorten this process to—”

"Ten minutes."

Luo interrupted him.

"A heart replacement can be done in ten minutes."

The transplantation of the two additional hearts, along with the reconstruction of the circulatory system, can be completed within half an hour.

"The power of the Op-Op Fruit, is it really that exaggerated?" the doctor murmured.

"The fruits of the surgery are in my hands; I can do more than you know."

Luo leaned the Ghost Cry against the edge of the lab table, took off his coat and tossed it onto the back of the chair, then turned his head slightly toward Luo.

(Please remember the website 20 ...

"Roy, are you the first one to be in charge?"

"certainly!"

"You and the doctor should discuss it as soon as possible."

"Next, I'll have the members undergo black beard gene implantation, followed by heart transplants!"

"No problem, Captain!" Gracia and Luo exchanged a glance and agreed at the same time.

.................................................. .........................................

The underground laboratory on Beehive Island, 3 a.m.

Dr. Gracia had been working for twenty hours straight, but he was more excited than ever.

A thick stack of gene sequence reports lay on the lab table, each page worn rough from being flipped through so many times.

"The last batch of black beard gene embedding surgeries have been completed."

He spoke to Roy and Luo, who were standing opposite him at the lab table, his voice hoarse but filled with barely suppressed excitement.

"In three days, all the core members of Beehive Island successfully had their genetic sequences embedded in Blackbeard's.

The rejection response was almost zero, and the gene fusion rate was all above 99.9%.

Luo leaned back in his chair, his fingers tapping lightly on the scabbard of the Ghost Cry sword.

He barely left the lab for the past three days, and the successive gene insertion surgeries gave him a deeper understanding of the significance of his work.

Multiple fruit ability transplantation.

If this gets out, the entire ocean will go crazy.

"Thanks for your hard work."

Roy took the final report from the doctor, flipped through a few pages,

"What's the status of readiness for the cloned heart?"

"All ready."

Gracia pressed a button on the control panel, and one side of the laboratory wall rose up.

Behind the wall, dozens of cloned hearts were neatly arranged, each heart immersed in a pale green nutrient solution and connected to an extracorporeal circulation system through tiny tubes.

"As per your request, the first batch of fifteen cloned hearts has been prepared, with two hearts in each set."

All the hearts were cultured using your individual cells, with a perfect DNA match, so there will be no rejection.

Roy closed the report and turned to look at Roy.

"The heart transplant will begin tomorrow morning."

Luo, are you ready here?

Luo opened his eyes, his pupils reflecting the stark white light of the laboratory.

"I have fully mastered the technology of heart connection."

A heart replacement takes ten minutes.

A complete three-heart transplant, including circulatory system reconstruction, can be completed within half an hour.

No need for open-chest surgery, no need for stitches, and no bleeding.

Trafalgar Rodden paused, his tone unusually serious:

"But there's one thing I must make clear beforehand—while the Power of the Op-Op Fruit can achieve non-invasive transplantation, my power will directly contact your internal organs during the surgery."

If any of you experience an instinctive rejection reaction during the surgery, even just a momentary muscle tension, it could lead to failure of the blood vessel connection.

"So?" Roy asked.

"Therefore, the surgery must be performed when you are completely relaxed and completely trust me."

Even the slightest lack of trust could lead to surgical failure.

The lab was silent for a few seconds.

Roy suddenly smiled, put the report on the table, and patted Roy on the shoulder.

"Luo, do you think we wouldn't trust you?"

Luo was silent for a moment, then lowered his head, a barely perceptible smile appearing at the corner of his mouth.

"Then there's no problem."

The next morning, the core members of Beehive Island gathered in the underground laboratory.

Barrett, Tesoro, Hawkeye, Crocodile, Yamato, Lucci, Saviour, Burgess, Red Earl Redfield, and others...

All the core combat forces on the island have arrived.

The laboratory was packed with people, and the atmosphere was much more somber than usual.

These usually ruthless and decisive powerful individuals were now silent, their gazes shifting back and forth between Roy and Roy.

"I'll go first."

Barrett was the first to speak, leaning against the wall with his arms crossed.

"I'm tough and resilient, I can withstand anything that happens."

Let Lao Tzu be the guinea pig.

"It's not your turn."

Tesoro leaned against the other side of the lab bench, golden arcs of electricity flickering twice on his fingertips.

"My Rumble-Rumble Fruit allows my body to become elemental, so even if there are any accidents during the surgery, I can protect myself immediately."

It would be more reasonable for me to be the first.

"In that case, my Sand-Sand Fruit ability will also work."

Crocodile, with a cigar dangling from his lips, exhaled a smoke ring, his tone as languid as ever.

"alright."

Roy's voice wasn't loud, but the entire laboratory fell silent instantly.

Roy stood up from the lab bench, walked over to Roy, took off his shirt, revealing his muscular upper body.

The light shone on him, illuminating the crisscrossing battle scars.

"Let me go first."

Roy's tone was calm, but every word carried an undeniable weight.

"The risks of this surgery are unknown."

Although Blackbeard's gene sequence has undergone three months of in vivo testing, no one can guarantee whether there will be any hidden defects when transplanted into us.

If even I don't dare lie down on it, why should you believe me?

"Besides, with my mental strength, my Mind Fruit can detect any abnormalities during the surgery immediately."

Roy turned around, his gaze sweeping over everyone present.

"Keep a close eye on them."

This is the key for our Beehive Island to surpass the World Government and the Four Emperors, and truly dominate this ocean.

And I—will be the first to grasp this key.

As soon as he finished speaking, a powerful aura of domineering power erupted from his body.
