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

Roy nodded in satisfaction as he watched the researchers quickly direct the installation of the equipment.

The value of scientists lies not only in the knowledge they possess, but also in their ability to explore the unknown.

"Roy the Kid,"

Kaido walked over and whispered,

"Wouldn't keeping these scientists from the world government around be a potential problem? What if they secretly pass on messages...?"

"Don't worry! The Doctor will keep an eye on them."

Roy's gaze was far-reaching.

"And they won't."

Even before Roy abducted these researchers, he had been silently implanting the instruction "You cannot betray Roy" deep within their minds.

If they try to contact the World Government, Roy's deep commands will prevent them from doing so.

Roy believed that these defenseless researchers could not possibly escape his control.

However, he had no intention of explaining any of this to Kaido, even though Kaido seemed quite serious about their alliance.

However, it's always good to be cautious and keep some things in reserve.

Seeing Kaido's still puzzled expression, Roy pointed to the busy researchers and offered a reason.

"Scientists value the research environment and results most."

"As long as we can provide what the world government cannot—genuine scientific freedom, rare research materials..."

Breakthrough technological support—they'll stay on their own initiative, and even… become our staunchest supporters.

Kaido nodded thoughtfully.

"Hmm...that makes sense. Just like the guys under my command, as long as there's alcohol to drink and a fight to fight, they're completely loyal."

Roy chuckled; the metaphor, though crude, was similar in essence.

In the following days, the research base entered a period of rapid construction.

Under Dr. Gracia's command and with the assistance of numerous pirates, various sophisticated equipment were moved into the designated laboratory, the wiring was connected, and the power supply was turned on.

The large amount of data seized from Punk Hazard was categorized and archived, and some core data began to be entered into the newly established database.

Inside the underground cold storage, those strange incubation chambers were properly housed, and a constant temperature system kept them in a stable dormant state.

Seeing that the experimental base had entered a stable development phase, Roy's plan finally came to an end.

Next, it's time to improve his strength. After all, there are still two years left, and Roger should be able to find the "final island" and then the "Great Pirate Era" will begin.

By then, the number of pirates will be far greater than it is now.

After a moment's thought, Roy stood up, his Observation Haki spreading out to find Kaido, who was drinking. His figure slowly rose up and headed to the training ground.

Roy's figure drifted over and landed in front of Kaido, who was drinking heavily.

"Kaido, the construction of the base is on track, and the doctor's research has also begun to advance."

"Next, it's time to enhance the capabilities of our core members."

Roy got straight to the point.

Kaido put down his gourd of sake and wiped his mouth. "Hmm? What are your thoughts?"

"At the entrance to the new world, there is an island called 'Thunder Island,' which is shrouded in violent lightning all year round, and its natural environment is extremely harsh."

Roy said slowly,

"That kind of environment is extremely beneficial for building physical strength and tempering willpower."

"Thunder Island?"

Kaido's eyes lit up.

"I've heard of that place. Do you want to cultivate there?"

"It's not just me."

Roy shook his head.

"If you're comfortable with that, I plan to bring my crew, as well as your men Jack, Maria, Ulti, and Page One. Yamato can come along if he wishes."

"Bring those brats?"

Kaido grinned.

"Runti and Page One are alright, but Jack has become much more obedient after being beaten up by Barrett, and he's been training like crazy."

Maria…that girl is a bit scheming, but her strength is decent. As for Yamato…”

A complex emotion flashed in his eyes. "That girl has been talking about getting stronger and defeating me every day lately. If I take her to Thunder Island, she'll probably train even more insanely."

"Having a sense of crisis is a good thing."

Roy laughed.

"Moreover, the younger generation needs to undergo real trials. The environment of Thor's Isle can not only forge the body but also test the mind. More importantly—"

He looked at Barrett and the others who were sweating profusely on the training field in the distance.

"We cadres also need an environment where we can engage in real combat, learn from each other, and push our limits. On Ghost Island, we ultimately can't fully unleash our potential."

Kaido pondered for a moment, then suddenly slapped his thigh.

"Alright! I've been itching to get started too! When are we leaving?"

Three days later.

Roy said, "We need to prepare some equipment, supplies, and Seastone. Also, we need to arrange for personnel to stay at the base."

"No problem! Queen staying behind to guard the house is enough!" Kaido said enthusiastically.

"At our speed, we can get back quickly if there are any problems."

The news spread quickly.

Barrett was so excited when he heard that he was going to Thor Island to train that he couldn't wait to leave.

The veterans of the Roy Pirates, who had already enjoyed rapid training there, were all beaming with excitement.

Moria, Vera, and Jack, Maria, Ulti, and Page One of the Beast Pirates who joined later were both nervous and expectant when they received Kaido's orders.

They had long heard of the infamous reputation of Raijin Island, but the opportunity to train under the guidance of powerful figures like Governor Kaido and Captain Roy was a rare one.

Upon hearing the news, Yamato rushed straight to Roy.

"Roy! I want to go too! I want to become stronger! I want to defeat Father!"

Roy ruffled her white hair.

"Yes, but you must follow orders. Thunder Isle is not an amusement park; if you're not careful, you really can die."

"I'm not afraid!" Yamato clenched his little fists, his eyes resolute.

Seeing the fighting spirit burning in Yamato's eyes, Roy nodded inwardly.

Despite her twisted upbringing, Kaido's daughter possesses an undeniable resilience and potential that should not be underestimated.

"Okay, it's settled then."

Roy withdrew his hand.

"We'll set off at dawn three days later. Everyone, get ready and bring enough supplies."

The news quickly spread among both pirate crews.

On Roy Pirates' side, Bullet, Hawkeye, Tesoro, Stella, Savi, Enel, Pea, Moria, and Vera all participated.

Almost the entire force was deployed, leaving only Dr. Gracia and a few technicians behind at the base.

The Beasts Pirates are led by Kaido and King, and include Jack, Maria, Ulti, Page One, and Yamato, who volunteered to join.

Quinn stayed behind to guard Ghost Island and the research base.

The Roy Pirates' Ark Maxim, and a medium-sized fast ship of the Beast Pirates.

Kaido stood at the bow of the clipper ship, watching Roy and his crew board the golden airship, and grinned:

"Roy, why don't we all ride on my ship? Your golden ship is too conspicuous."

"It is precisely because it is conspicuous that it needs to be shown more often."

Roy ascended to the Proverbs, turned back, and said,

"The World Government's attention is now focused on us. The characteristics of the Ark Maxim are too obvious. If we suddenly disappear, it will arouse suspicion."

Let it occasionally appear in the Navy's field of vision, attracting attention, while we...

"Hehehehe... How insidious! Let's do it this way!"
