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

Kaido, King, and Queen all stopped in their tracks at the same time.

Even Roy, who already knew the situation, was still shocked when he saw this scene again.

The incubation chamber on the left side of the passageway contains the "human" appearance.

They look exactly like the core members of the Roy Pirates!

Barrett, Hawkeye, Tesoro, Crocodile, Kuma, Cyrus, Savi, Enel, Pea, Charon, Yamato, and even Stella and Scarlett... Except for Roy himself (whose original embryo is in the laboratory further inside), almost everyone here has a "clone"!

The incubation chamber on the right side of the passage corresponds to the main officers of the Beasts Pirates!

Besides Kaido, King, and Queen, there are also Jack, Ulti, Page One, and Maria, these are the core members of the Beasts Pirates!

The "clones" were not completely still; their chests rose and fell slightly with the flow of nutrient solution, as if they were breathing gently.

The body's muscle lines are smooth and perfect, and there is a faint glow flowing under the skin, revealing a vigorous vitality and a sense of hidden power.

Most notably, aside from a few clones of individuals like Kaido, King, Moria, and Kuma who possess special bloodlines,

The physical characteristics of most other clones underwent subtle and harmonious changes!

Some of them have faint, keratinous patterns on their skin that resemble those of the demon race.

A faint, flame-like glint occasionally flickers across the ends of some hairs or beneath the skin (a characteristic of the Lunaria race).

Some skeletons appear more robust and powerful than their original form (a characteristic of the Bakania people)...

However, these abnormal characteristics are not abrupt; rather, they seem like natural expressions that were originally hidden deep within the genes and are now being optimized and activated.

It blends perfectly with the overall appearance of the clone, even adding a strange sense of beauty and power.

"This...this is..."

Even the well-traveled Kaido stared wide-eyed at this moment.

He carefully examined the "embryos" that looked identical to his subordinates but exuded a different aura.

Jin's pupils contracted slightly, his attention particularly drawn to the embryos glowing with the faint light of the Lunaria flames.

Quinn even took off his cigar, opened his mouth wide, and his eyes behind his glasses were filled with the burning brilliance of a mad scientist seeing a perfect creation.

As you can see,

Dr. Gracia's voice, tinged with pride, echoed through the quiet corridor.

"These are the 'bloodline fusion embryos' that I have carefully nurtured for you all!"

He walked up to a culture chamber labeled "Tezzolo," and reached out to touch the cool glass as if admiring the finest work of art.

"Previous test subjects, due to technical limitations..."

Significant physical changes often occur after transplantation.

Moreover, one can only inherit a portion of, and only the explicit, bloodline abilities; the potential is locked, preventing it from reaching its most perfect state.

The doctor turned around, his gaze sweeping over Roy and Kaido's group of four:

"But these embryos now are completely different!"

"We use the somatic cells provided by you as a blueprint, and use them as the 'main framework'."

Then, they selected from Kaido's Oni bloodline, Mr. Jin's Lunaria bloodline, and Mr. Kuma's Bakania bloodline.

The most essential, stable, and universally applicable gene fragments.

"Through the original 'bloodline factor targeted chimerism technology',

We will perfectly embed these optimized alien genes into key and complementary positions in your main gene chain, just like assembling the most intricate building blocks.

The entire process is completed in the early stages of cell division, ensuring the natural and coordinated development of the embryo throughout its life cycle.

The doctor pointed to those embryos:

"So what you're seeing isn't a simple 'piecework monster,'"

Instead, it is a 'new human' embryo that naturally grows towards a more optimized and stronger direction from the very beginning of life!

They possess an appearance highly consistent with your original forms, while harmoniously incorporating the superior traits of three unique bloodlines!

"After transplantation, these superior traits will not immediately manifest as exaggerated 'abilities'."

That would actually cause physical strain and instability.

They will deeply integrate into your body's foundation in the form of 'potential'!

Dr. Gracia became more and more excited as he spoke.

"This means that after the transplant, you all need to train your muscles and develop an imposing aura, just like you would train your muscles."

Through long-term, systematic, and high-intensity training, we can gradually "awaken" and "unearth" these dormant potentials!

As the training progresses, the terrifying regenerative abilities and physique of the Oni race, the physical defenses and fire affinity of the Lunaria race, and the immense strength of the Bakania race...

These abilities will gradually emerge in a way that best suits each individual's unique characteristics.

And ultimately reach or even surpass the strength of the original bloodline holder!

"Moreover, because of the perfect fusion that begins in the embryonic stage,"

There will be no malignant changes in appearance, and the rejection reaction is almost zero!

This is the evolution of life, a ladder to a higher level of life!

The passageway was completely silent.

Kaido, King, and Queen were all stunned by the detailed explanation and the perfect embryo before them.

They can sense the life fluctuations contained within those embryos, which are of the same origin as themselves but are even more profound and pure.

Roy took a deep breath and looked at Dr. Gracia:

"Doctor, so you mean, after transplanting the 'optimized bloodline' provided by these embryos..."

By diligently training, we can steadily acquire the core advantages of three special bloodlines.

And there are no side effects, right?

"Theoretically, yes!"

Dr. Gracia nodded vigorously.

"Of course, when it comes to each individual, due to differences in their original physique, Devil Fruit abilities, and training direction..."

The final emphasis and form of expression will differ.

But a comprehensive, fundamental improvement is inevitable!

"Hehehehehe... Hahahaha!!!"

Kaido suddenly burst into a deafening laugh, the sound echoing through the passageway and making the glass vibrate.

"Great! Excellent! Doctor, you did a fantastic job! This is practically a path to evolution tailor-made for me!"

His eyes burned with an intense flame, an endless thirst for greater power.

"My demon bloodline is already powerful; if I could perfectly fuse the flames of the Lunaria race and the power of the Bakania race..."

"Hehehe! On this vast ocean, who can stop me?!"

Jin remained silent, but his slightly trembling shoulders betrayed his inner turmoil.

The talents of the Lunaria race combined with the physique of the Oni race and the power of the Bakania race...

This might allow his strength to reach that legendary level...

Quinn licked his lips, already fantasizing about how, with a stronger physique, he could withstand even more and more insane mechanical modifications...

The last trace of doubt in Roy's heart completely disappeared.

Looking at the embryos on both sides of the passage, representing the infinite possibilities of his partners' future, a sense of pride and responsibility welled up within him.

"PhD,"

Roy's voice was firm and clear.

"Now that everything is ready, let's begin."

"It starts with me."
