Uchiha Gate: From Konoha to One Piece

— — — — — — — 

Uchiha Mikoto chuckled softly and said, "I'm fine with anything! Whether it's the Navy or pirates, it's not a problem!"

"But, Kaito, Auntie," she continued, "I think if our people are going to join the Navy or other factions, it's best to hide our chakra, ninjutsu, and obvious kekkei genkai abilities—like our Uchiha Sharingan."

"Alternatively, for infiltration missions, we could just use contractors from the Pirate world."

"Otherwise, if the ninja power system gains fame in this world, it'll easily attract the attention and suspicion of the major factions."

"They might even figure out that we're all connected."

"The World Government isn't foolish; they'll do whatever it takes to acquire these powers."

"Unless we're willing to start spreading the techniques for chakra refinement and ninjutsu across the Pirate world right now."

"But the cost of that would be immense. It would significantly boost the future strength of our enemies, which is not acceptable."

The basic chakra refinement techniques won't enable people from the Pirate world to extract chakra.

From what she knows, only Kaito's Primal chakra refinement method can achieve this effect.

But the primal chakra refinement method is far too precious.

This is a foundational technique that allows individuals to continually extract chakra through daily practice, improving its quantity and quality, ultimately elevating their energy levels and even influencing their life force.

There's no way it should be shared with non-contractors.

"Or maybe, Kaito, could you create a simpler chakra refinement method? Something based on the ninja world's standard techniques but modified to let ordinary people form their own chakra seeds and extract chakra?"

Mikoto turned to look at Kaito as she spoke.

Kaito shook his head firmly. "That won't work!"

"Anything that involves forming one's own chakra seed touches the foundation of the chakra system. It's tied to the essence of the Primal chakra refinement method."

"Smart people could very likely use that as a stepping stone to develop a true primal chakra refinement method or something with similar effects!"

"I never underestimate the intelligence of others!"

"So, spreading chakra under the guise of confusion isn't feasible."

"In the Pirate world, only contractors can use chakra and ninjutsu."

"At least for the foreseeable future, that's how it will stay."

The main reason is the abundance of physical training resources in the Pirate world. The people there have bodies and life forces far stronger than those in the ninja world.

If the primal chakra refinement method were spread widely, or if someone like the Sage of Six Paths disseminated chakra as he did in the Ninja world, the Pirate world would inevitably descend into chaos.

Chaos so extreme it couldn't be suppressed.

It would be like opening Pandora's box—a box that should never be opened.

Kaito does want to change the Pirate world and establish a new order.

But even a new order wouldn't eliminate the evil in human nature.

When people gain extraordinary power, they often become restless, wanting to take shortcuts or break rules.

The efficiency of turning chakra talent into strength is far higher than physical training, haki or swordsmanship in the Pirate world.

Thus, it must not be spread.

Kaito explained his thoughts to Mikoto and the others.

"Hiss! That's terrifying!" Mikoto gasped, feeling a chill of fear. "I can't even imagine the chaos that would erupt if something like the primal chakra refinement method and ninjutsu were spread in a world as vast as this."

"It'd probably make the Warring States period in the ninja world seem a thousand times more chaotic!"

Consider this: in the Pirate world, the World Government alone has 170 allied nations.

Non-member nations, including those under the Four Emperors, number over a hundred.

In total, there are more than 300 nations in this world.

Far more than the ninja world.

Not to mention the countless small islands, towns, and villages.

And if sea kings, beasts, and other creatures could also master chakra... the thought alone is horrifying.

Can you imagine the scale of chakra those massive sea kings and beasts could extract?

It'd be immense.

At that point, all sea beasts, sea kings, and predators would become exponentially stronger.

Humanity might even face extinction.

It's not an exaggeration.

High-level sea kings and beasts are already as intelligent as humans.

If they could enhance their species' power, do you think they wouldn't spread chakra among themselves?

"The primal chakra refinement method absolutely cannot be shared," Mikoto declared firmly. "Chakra must not be spread."

"Otherwise, the consequences will be unimaginable!"

"Only contractors bound to Kaito in the Pirate world should have access to chakra! This rule must be written into the contract's prohibited clauses."

Uchiha Naori nodded solemnly, his face grave as he clearly understood the catastrophic potential.

"Done!" Kaito confirmed, nodding decisively. With a thought, he added this clause to the Space-Time Gate contract.

In an instant, all contractors received the update.

Initially, some were confused, but after learning the reasons, everyone understood.

People like Koshiro and other residents of the Pirate world even strongly supported it.

"Since we can't freely spread the chakra refinement method," Kaito concluded, "those infiltrating the major factions in the Pirate world must either conceal their chakra and ninjutsu or use native beings from this world."

"As for whether Mikoto and the others join the Navy or the pirates in the future, that decision can wait a few years. You're all still young and don't need to rush."

Kaito made the final decision.

The Navy in the Pirate world does have age requirements for recruitment.

They don't accept children who are too young.

Unlike the ninja world, where it's not uncommon for five- or six-year-olds to graduate and become ninjas.

"Fair enough," Uchiha Naori agreed with a nod. There wasn't much to debate here.

"By the way," Naori suddenly remembered something. "Yesterday, the Toads from Mount Myōboku mentioned that the Great Toad Sage had some connection with the Sage of Six Paths."

"Apparently, he was tasked with monitoring and maintaining some balance in the Ninja World."

"While the Great Toad Sage promised not to reveal the current situation in the Ninja World to the Sage of Six Paths and would cover for us, we can't rule out the possibility that the Sage of Six Paths has other ways to monitor the Ninja World."

"We should prepare for the worst. If he discovers something suspicious and decides to intervene, we need a way to counteract him. What do you think?"

Naori had intended to bring this up earlier but had been too preoccupied with other matters.

"Hmm, you're right."

Kaito's expression turned serious. "This is definitely something to address."

"Here's what I'll do: I'll add a safety feature to the teleportation mechanism. If anyone encounters an unbeatable opponent, the system will trigger an automatic teleportation to the Space-Time Gate dimension."

"I'll also designate a special area within the Space-Time Gate as a base for living, training, and operations.

"This way, if neither world is safe to escape to, contractors can retreat there. It'll serve as our ultimate safe haven."

As Kaito grew stronger, the Space-Time Gate dimension expanded accordingly.

Currently, its diameter exceeded 120 kilometers, with a height of over 100 kilometers.

It was massive.

The storage spaces allocated to contractors took up only a tiny fraction of this area.

Building a base capable of sustaining a population of one million was well within its capacity.

"Wait, really? Is there enough space for that?" Naori asked, clearly unaware of how large the dimension had become.

Mikoto and the others also looked over curiously.

"Plenty of space," Kaito chuckled. "Don't forget, the Space-Time Gate expands as I grow stronger."

"Right now, its diameter is over 120 kilometers, with a height exceeding 100 kilometers."

"If I use my permissions creatively, I could even stack multiple layers, creating countless bases if necessary."

"However, constructing a functional and fully equipped base will require a lot of materials and furnishings."

"We'll need to source these from both the Ninja World and the Pirate World."

"Alternatively, we could set up furniture and construction material factories in Konoha, hiring workers to produce what we need."

"This approach might even boost Konoha's economy and industries. It's worth planning out properly."

"There's no need to rush, though; we can build the base gradually."

"As for the main structures, I could handle those myself using my permissions or enlist Hashirama's Wood Release abilities."

Speaking of which, Kaito checked on Hashirama's favorability toward him. It had reached 81 points—just enough for a contract.

Suddenly, Kaito realized how useful Hashirama was.

He was practically an engineering marvel!

Resurrecting Hashirama was undoubtedly one of his best decisions.

"I need to give him more and more tasks."

Meanwhile, on a construction site in Konoha's old district, Senju Hashirama sneezed several times in a row. He rubbed his nose and muttered, "Who's talking about me?

"Why do I have this bad feeling that something troublesome is about to happen?"

Sighing, he glanced at the ongoing construction. "When will this project ever be done?"

"If only the Senju clan had more people who awakened Wood Release…"

"Then again, I heard that Tobirama recently proposed restarting experiments to awaken Wood Release."

"Apparently, they won't use random test subjects anymore. Experiments will be limited to enemies, criminals, and mainly Zetsu clones."

"That's at least more humane, so I can accept it."

Hashirama wasn't usually one to approve of Tobirama and Orochimaru's experiments.

But this time, he felt it might be worth considering.

After all, the benefits would undoubtedly go to the Senju clan first, significantly aiding its revival.

It was clear to Hashirama that Tobirama's primary motivation for pursuing these experiments was to restore the clan's former glory.

Considering the Senju clan's decline, which was partially due to his own decisions and policies, Hashirama felt a strong sense of responsibility.

If the Senju couldn't recover, Tobirama might never truly forgive him.
