I will use the ninja world to aid my cultivation of immortality.

She was overjoyed and nuzzled Naraku's leg again in a flattering manner.

Normally, Naraku wouldn't mind ordering additional packages.

But I'm not in the mood now.

Nothing else, important matters need to be taken care of.

The list he just handed over was a compilation of cultivation resources he had gathered over the past few days by comparing resources in this world.

Some are rare flowers and herbs that can be cultivated into special spiritual medicines, while others are materials for refining magical treasures; the variety is quite extensive.

Just like spiritual energy.

In addition to the fact that the spiritual energy in the One Piece world is much denser than that in the Ninja World, the resources for cultivating immortality are also much richer.

This can actually be seen from the sea kings.

If resources were not abundant, how could such enormous and numerous sea monsters have been bred?

same.

The benefits of power are once again evident.

There's no need for Naraku to go through the trouble of searching; with a single command, there are plenty of people to do the work.

"It's almost time to break through!"

After dismissing Monet, Naraku also got up and left, heading to the palace where he trained.

With his five hearts facing upwards, Naraku, sitting cross-legged on a soft cushion, took out the energy crystal refined from Kaido's fruit and the five demon gems from his inner space.

The former needs no further explanation.

The latter is a demon gem that has been tempered by the original body.

Pica and the others who went out have returned safely.

The number of Devil Fruits and Devil Fruit users brought back was close to twenty.

Most of them belonged to the original body, while a small portion was used by Naraku to break through to the Foundation Establishment stage.

He unleashed his true energy, setting up a barrier to seal off the palace.

Then Naraku cautiously created a shadow clone of his true energy as a guard.

With everything prepared, he began to absorb the energy crystal and the demon gem.

Time passed little by little.

Within the city of Dressrosa.

"Hey? Look at the King's Heights!"

"A whirlwind? Why did a whirlwind suddenly appear above the palace?"

Is this some kind of new weather phenomenon?

"There seems to be no danger. The whirlwind is just hovering over the palace and shows no sign of descending."

"."

As the first person noticed the anomaly above the King's Highlands, more and more people stopped and stared in astonishment at the whirlwind that had suddenly swept up the King's Highlands.

The weather along the Grand Line is unpredictable, especially in the New World.

This undoubtedly fostered people's strong capacity for acceptance.

The whirlwind that suddenly swept up on King's Heights was certainly surprising.

But after observing for a moment, and realizing that the whirlwind was merely enveloping the area without descending or causing damage, the people of Dressrosa quickly returned to calm.

They even viewed the whirlwind of the King's Highlands as a spectacle.

Inside the royal palace.

Just like a whirlwind rising in the sky.

The energy crystal from Kaido's Devil Fruit, along with the five Demon Gems, successfully enabled Naraku to break through to the Foundation Establishment stage.

In a state of perfect harmony with nature, a large amount of spiritual energy gathered, forming a vortex that flowed into Naraku's body, supporting his transformation after breaking through his cultivation level.

The spiritual energy in this world is far richer than that in the ninja world, which was severely damaged by the divine tree.

This makes the transformation after the breakthrough faster than it was in the Ninja World.

Day by day passed.

In less than ten days, the whirlwind over the King's Heights gradually dissipated.

Inside the palace.

With its five hearts facing upwards, Naraku successfully completed its transformation after absorbing the last wisp of spiritual energy, marking the end of its long-term process.

With her eyes slightly closed, she slowly opened her mouth.

Exhaling like an arrow.

As he exhaled a breath of stale air, the breath shot forward like an arrow from a powerful bow, striking the palace wall.

hum! !

The sealed barrier rippled.

Such a commotion is enough to prove the strength of their aura.

If it weren't for the protective barrier, Naraku's breath would have pierced through the palace walls and flown outside.

"It's still more comfortable to use magic."

Her body was as light as a feather.

With a burst of magical power, Naraku gracefully took to the air.

He lowered his legs, which had been crossed, and placed his feet on the ground.

Naraku moved his body freely while sensing the magical power within him.

Compared to true qi, magical power is of a much higher quality.

This allows Naraku to now unleash a casual attack with power surpassing his full-force attack before his breakthrough.

Sensing the changes after his breakthrough, Naraku silently assessed his current strength once again.

Hmm. It's quite different from when I broke through to the Foundation Establishment stage.

The difference doesn't come from magical power, but from supernatural abilities and magical treasures.

When the main body broke through the Foundation Establishment stage, the "Five Elements Technique" had already been partially mastered.

By contrast.

Although the "Blood Soul Technique" surpasses the "Five Elements Technique," it is still at a level that is not even at the beginner level, so it is obviously no match for the "Five Elements Technique" at the minor completion level.

Needless to say, magical treasures are another story.

As an embodiment.

Not only does Naraku lack magical artifacts like the Eternal Mangekyou Sharingan, he is also unable to summon the Bronze Tower projection like his original self.

Let's take the power levels in the Naruto world as an example for comparison.

His current strength may not be able to surpass that of Hamura Otsutsuki, the ancestor of the Hyuga clan.

"I wonder if there's a hidden upper limit to combat power in this world," Naraku pondered, stroking his chin.

His knowledge of the One Piece plot is limited to the Wano Country arc.

This also limited his understanding of the combat power in One Piece to this point.

If we take the Wano Country arc as the end, the power ceiling of One Piece is lower than that of Naruto.

The main reason is that Naruto features the extraordinary Otsutsuki clan.

This clan, including the hybrid Otsutsuki Hagoromo and Otsutsuki Hamura, significantly raised the power ceiling in Naruto.

Thinking of the Five Elders, whose fates remain unknown, and Im, who is suspected to be the final boss, Naraku felt it was best to be cautious.

Using Naruto as a reference, who knows if One Piece will also see a major leap in power levels later on?

"Let's get our hands on the resources we can collect first, and then we can continue to improve our strength while increasing our efforts." Naraku quickly made up his mind.

"finally reached!"

A fleet of more than ten pirate ships sailed on the sea, and gradually, the outline of an island appeared on the sea ahead.

As the island drew ever closer, Jin, with his right hand resting on the hilt of his sword, stood atop the main ship, his eyes narrowing slightly.

That's right, the fleet right now is from the Beasts Pirates.

After several days of sailing, Jin's troops finally arrived in Dressrosa.

"Don Quixote, I wonder if the other side has any other powerful characters besides Doflamingo."

"Xiao Pei, you're not allowed to run around later. Remember to stay with me."

"Okay, sis!"

As they approached Dressrosa, the rest of the fleet came aboard, including Ulti and Page One from the Flying Six.
