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

Roy's idea made Dr. Gracia's eyes widen even more.

A few seconds later, he slammed his hand on the control panel.

"Genius! Captain Roy, you are a true genius!"

"In this way, we've moved the most dangerous 'fusion process' outside the body, letting the clones take the risks instead of us! And..."

Dr. Gracia quickly brought up the computing interface, and after a series of complex operations...

"If cultivation begins from the embryonic stage, multiple bloodlines have enough time to naturally adapt and achieve balance!"

Success rate... Good heavens, the theoretical success rate can reach over 90%!

Kaido grinned.

"Hehehe... Interesting! Let's do it! Just tell me what resources you need, and I'll give you my full support!"

Jin nodded.

"This is the safest option."

"What would a clone be like?" Moria asked curiously, his perspective somewhat peculiar.

"Clonations are bred for experiments and have no self-awareness. Moreover, we can breed multiple clones for backup to ensure that we always have fresh material."

As Gracia explained, he began frantically typing on the console.

"It's technically entirely feasible!"

"We have complete cloning technology, gene samples from three adults, and advanced equipment stolen from Punk Hazard!"

If all goes well, the first batch of 'bloodline fusion embryos' can be cultivated within a month!

He pulled up a complex breeding program,

"The first step is to extract pure gene samples from the three adults;"

The second step involves preliminary 'weaving' at the gene level in vitro to form a stable multiple gene template.

The third step is to implant the template into a blank embryo and begin the cultivation process;

The fourth step is to accelerate the cultivation process by allowing the embryos to grow rapidly in a special culture medium and energy field.

The fifth step is to extract tissue samples for testing after the clones have matured.

Roy carefully examined the plan: "How long will it take to accelerate the cultivation?"

"Under normal circumstances, it takes eighteen years for a person to fully mature."

The doctor provided the data,

"But if we use a high-concentration nutrient solution, we can theoretically reduce the cultivation time to a very short time."

"Then what are we waiting for? Let's get started!" Kaido's eyes lit up.

He could already imagine his subordinates becoming invulnerable to Jin's blades and spears, combined with the immense strength of his own demon race.

When we engage the enemy, they'll be shocked.

"No rush. Let's address a few key issues first."

Roy waved his hand to interrupt Kaido, then looked at the Doctor.

"First, the specific plan for gene 'weaving'. In what proportion and in what way should the Oni, Lunaria, and Hybrid Oni bloodlines be fused for maximum stability?"

"Can the racial characteristics be fully displayed?"

"This requires a lot of simulation calculations."

The doctor brought up the gene simulation interface.

"I will provide a preliminary plan within three days."

"Second, the 'consciousness problem' of clones."

"We are cultivating organ carriers, not complete people."

"I don't want someone who looks like me to be killed or anything like that!"

Roy's expression was serious.

"Doctor, you must ensure that the clone has no self-awareness."

"That's entirely possible."

"We can use 'neural inhibition technology' to block the development of higher brain functions during the embryonic stage."

Such a clone would possess basic vital signs, but would lack consciousness and the ability to perceive pain.

"Third, and most importantly..."

Roy looked out the window.

"It's a matter of secrecy. If this technology were to leak out, the whole world would go crazy."

We must establish the highest level of security measures.

"I'll arrange the base's defense level later. The Beasts Pirates members will increase patrols here; they're not allowed to enter the base without orders!"

Flames rose behind Jin, and he solemnly assured him.

Kaido grinned.

"I'll also send that kid Quinn to protect this place. He's come up with a lot of new gadgets lately, so it'll be good to test them out."

"Quinn? Being the second strongest fighter under Kaido is quite impressive."

Roy thought for a moment and then agreed.

"good!"

"Then it's settled."

In the following days, the research base entered an unprecedented state of activity.

All researchers stopped their current research projects and prioritized working with the doctoral student.

Kaido, King, and Moria provided a large amount of blood.

During this time, Roy also provided his own blood sample, allowing the doctor to prioritize using his genes as the primary source.

Bloodline fusion is performed to create clones.

The PhD student led his team to work day and night to calculate the best gene fusion scheme.

On the evening of the third day, the doctor found Roy with a thick stack of reports.

"Captain Roy, the initial plan is ready."

"Based on your genes, we have identified several of the most stable gene fusion patterns."

"Very good!" Roy praised.

"Doctors, you should begin cultivating them now."

"You decide which model to adopt."

Roy handed the report back to the doctor.

"I'm not as knowledgeable about the scientific details as you are, as long as the final result is safe and effective. But there's one thing to remember—"

Roy looked at the doctor, his gaze serious:

"Regardless of the model adopted, 'controllability' must be the first principle. It is better to have slightly worse results than to risk losing control."

"clear!"

The PhD student nodded emphatically.

"I will start with the most conservative approach and then gradually optimize it after accumulating enough data."

Roy nodded, then turned to look at Kaido and King.

"We shouldn't have anything to do for the next few months."

"You two can stay in Wano Country or return to Raijin Island to continue your training."

Kaido stroked his chin and thought for a moment.

"I'm staying here because the improvements I gained from Thunder Island are no longer significant."

Moreover, bloodline fusion is a major event; I need to witness it personally to feel at ease.

The flames behind Jin flickered slightly.

"I'm also left with the defense arrangements for Ghost Island and the base to be arranged by me."

"Alright then."

Roy agreed, then looked at Gracia one last time.

"Doctor, I'm leaving this to you."

Please let me know if there are any updates.

"Don't worry, Captain Roy!" the doctor assured him, patting his chest.

With everything arranged, Roy led Moria away from the research base.

Instead of taking a boat, the two took to the air—Roy enveloped Moria with his mental energy and flew towards Raiden Isle.

On the way, Moria couldn't help but ask,

"Boss, are you really completely comfortable entrusting such an important experiment to the doctor?"

"Furthermore, Kaido and King are both on Onigashima, where we don't have any significant fighting force. What if they..."

"Trust those you employ," Roy replied calmly.

"The Doctor's loyalty is beyond doubt. And if Kaido and his crew dare to break the alliance..."

"Don't forget, there are still a few members of the Beasts Pirates on Raijin Island, and even Kaido's daughter is there."

Roy looked at Moria,

"Even if Kaido doesn't care about his subordinates, the current Beasts Pirates can't withstand the Roy Pirates' purge."

Roy was quite confident about this.
