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

Seeing that Savi had succeeded, everyone gathered around and asked him questions.

This made Savi feel smug, and he excitedly gave Barrett a victory sign.

Seeing that his younger brother, who was from the same country, was safe and sound,

Barrett breathed a sigh of relief, walked over and patted Savi on the shoulder.

"Good job, kid. But don't get cocky, this is just the beginning."

"I know, Brother Barrett!"

Savi clenched his fist.

"I will definitely try my best to catch up with you!"

"alright!"

Roy clapped his hands and looked at the others.

"Next is Tesoro. Your control over life restoration is comparable to Savi's, but you are a Logia-type Devil Fruit user."

"But the elements in the Natural type might differ from those in the Zoological type, and the processes might vary. Are you ready?"

"Hehe! Boss! I can't wait any longer!"

Tezzolo stepped forward with a grin.

With Savi's experience, Tezzolo's guidance process went much more smoothly.

Roy probed Tesoro's body with his mental energy and discovered that the Logia-type ability—under the influence of elementalization—made the process simpler and safer for Tesoro.

In the event of danger, Tesoro's body can always automatically transform into its elemental form to avoid risk.

"Interesting," Roy murmured.

"This is one of the advantages of being a Logia-type Devil Fruit user."

Tesoro entered a meditative state under Roy's guidance. In Roy's perception, the most difficult part for Tesoro was sensing the Armament Haki energy particles.

After sensing the Armament Haki energy particles, incorporating them into his bloodstream was almost effortless for Tesoro.

The next step is to familiarize yourself with the process and try to prevent your body from entering the elemental state.

Half an hour later, Tezzolo also completed his first cycle.

"How are you feeling?" Roy asked.

"Great! Thank you, boss!"

"Very good, you go stay over there and continue to practice this skill."

Next, Roy taught everyone the techniques of "internal forging".

Aside from Vera, who didn't meet the standard, even Moria, who joined at the same time, mastered the skill with Roy's help.

This also completely dispelled Moria's frustration about Roy drawing his blood for experimental purposes.

On the contrary, he was somewhat grateful to Roy for directly teaching him so many combat techniques.

In addition, Moria's strength has increased rapidly since he was captured by Roy, which has made him gradually feel a sense of belonging to Roy's pirate crew.

For the next few days, the Roy Pirates remained gathered on the outskirts of Raijin Island.

Roy guides his partners in "internal forging" every day, promptly correcting any deviations that occur during their training.

To deepen their understanding of this technique.

A week later, everyone's progress was clearly visible, and everyone could skillfully enter this state.

Vera watched her companions succeed one by one, feeling both envious and anxious.

"Boss Roy, I..."

Roy looked at Vera,

"Your problem lies in your physical foundation. You have relied on the Venom-Venom Fruit for a long time, resulting in a serious deficiency in your physical strength."

"Starting today, we will triple the physical training every day, and I will have Stella personally supervise us."

"I'll teach you this technique later, don't worry!"

"Yes, boss!"

Time continued to pass, and another six months flew by. After everyone was able to cultivate on their own, Roy returned to the area where he could cultivate.

During this time, he and Tesoro would periodically use the "Ark Maxim" to travel to various islands.

While procuring some necessary supplies, they were also diverting the navy's attention.

While Roy, Kaido, and the others were focused on their training, some major events were happening on the high seas.

For example, the outbreak of the Battle of Etwol, the fateful battle between Roger and Shiki.

Ultimately, aided by the storm, the Golden Lion Fleet was defeated, and the Golden Lion himself was disgraced by having his head stuck into the ship's rudder during the battle.

Meanwhile, Roger's pirate crew, who were on the side of fate, continued their voyage unscathed.

This further enhanced Roger's reputation.

This also shifted most of the Navy's attention to the Roger Pirates.

In an effort to salvage its reputation, the Navy dispatched its "Three Great Monsters" to various locations to capture pirates.

They went so far as to promote the reputation of the Navy, and the "Three Monsters" Sakazuki, Borsalino, and Zan were promoted to the list of Navy Admiral candidates.

Thus, they acquired their respective titles: (Akainu Sakazuki), (Kizaru Borsalino), and (Aokiji Kuzan).

Another piece of news is that "World Destroyer Bandiworldd has been arrested by the Navy, and his followers have scattered."

Bondiward was imprisoned in the underwater prison.

The remaining events are mostly minor incidents.

such as:

The Don Quixote Family Returns to the North Sea, Taking Full Control of the Underworld!

Crocodile, the new Logia-type Devil Fruit user of the Sand-Sand Fruit, defeats a veteran Marine Vice Admiral!!!

"A contemporary supernova nicknamed 'King of the Lizards,' a Zoan-type Ancient Zoan Devil Fruit user, is making a powerful foray into the New World!!!"

The rest are just news about the various pirate crews in the New World fighting over territory.

These things have no impact on the current Roy Pirates.

Roy had some understanding of this information and knew about the current state of the ocean.

On Thunder Island, Roy and the rest of the Beast Pirates were still training as usual.

On this very day,

Tesoro returned from his shopping trip, and as both sides were receiving supplies, Roy's Den Den Mushi suddenly rang.

"Brubrubru—Brubrubru—"

Roy answered the phone, and Dr. Gracia's excited voice came through.

"Captain Roy! Good news! The preliminary bloodline analysis is complete!"

"Oh?"

Roy's eyes lit up.

"How exactly do you mean it?"

"Kaido's demon bloodline, King's Lunar Fiend bloodline"

Furthermore, the suspected mixed demon bloodline in Moria has already undergone basic genetic sequencing.

The doctor's voice was filled with excitement.

"More importantly, we discovered a complete record of the world government's bloodline transplant experiments in those culture chamber samples!"

"Based on these records and my theories, I have initially constructed a model for blood vessel transplantation!"

Roy took a deep breath, suppressing his excitement.

What is the success rate?

"Theoretically, it's 70%! But we need to do actual testing. And..."

The doctor paused for a moment,

"The recipient must have an extremely strong physique and recovery ability, otherwise they are likely to collapse due to rejection."

"I understand. I will return to you soon to continue the experiment and further optimize the process."

After hanging up the phone, Roy fell into deep thought.

Bloodline transplantation... If it can be successful, it means they can mass-produce powerful individuals with special physiques.

The Oni race's superhuman strength and regenerative abilities, the Lunaria race's fire and defense, and possibly even the characteristics of other rare bloodlines...
