One Piece: Hell Pirates

Chapter 449 449: The Development of the One Piece World

Western Underworld, Underworld Temple.

Jin, the Western Underworld God, had entered a state of extremely serious training.

For beings like gods, several thousand years were merely a period of duty. One or two years were no more than a short rest.

He had secretly monitored the Underworld Realm for more than a month. After failing to find Brook, he finally settled down and focused on increasing strength.

That mutated soul had been able to survive in the Northern Underworld for so long. Either it had died there, or it had truly found a way to thrive in that place.

That possibility made Jin feel a faint threat.

To avoid an accident like the one that had happened to the Northern Underworld God, Hirasaka, he had to be even more vigilant during this final thousand years.

Any threat had to be crushed in the bud.

However, the Ōtsutsuki clan lived within the Northern Underworld. If that mutated soul went there, it would most likely have no chance to develop.

Unless it could overthrow the Ōtsutsuki clan.

Only then would it have a chance to grow into a god-level powerhouse.

A star field under the jurisdiction of a lower-level hell in the Sangri Domain did not possess enough divine source power to produce so many god-level powerhouses.

Meanwhile, Brook's soul clone was carefully hiding itself in the Western Underworld, searching for the Underworld path it had entered through back then.

Now, not only did he possess the concealing power of the Eastern Underworld Yama clone and the Western Underworld Sealing clone, but he also had his own special soul.

For a short period of time, even Jin, who was in training, could not detect him.

Brook found the section of the Underworld Road where his soul had merged with the power of the Underworld years ago.

He did not dare absorb the ghostly energy and Underworld power here again, afraid it might disturb Jin.

But how was he supposed to return to the One Piece world now?

Brook's expression became grave.

Back then, it was the power of the Yomi Yomi no Mi that had protected his soul and allowed him to return to the One Piece world.

The power of the Devil Fruit had been born from the willpower and sacrificial power of the humans in the One Piece world, obtaining a trace of Jin's authority.

There were many life-bearing planets under the jurisdiction of the Western Underworld, and Brook did not know how to lock onto the One Piece world.

His Revive Revive ability had already been completely separated from him, leaving no trace behind in the One Piece world.

What should I do?

Brook lay hidden on the Underworld Road, looking utterly helpless.

"I wonder, after I left with the power of the Revive Fruit, did another Yomi Yomi no Mi appear or reincarnate in the One Piece world?"

Brook muttered to himself.

"In the original story, Vegapunk once said that as long as someone remembers the name of a Devil Fruit, that Devil Fruit will not disappear. As long as living beings still have willpower and desire, that power will always exist."

It really was an incredible planet.

But that was not too exaggerated.

The Western Underworld had the One Piece planet, while the Northern Underworld had the Ōtsutsuki clan, a god-slaying race. Compared to that, the One Piece world was not the most outrageous place.

Thinking of Ōtsutsuki Shibai from the Northern Underworld, who had already ascended and broken free from the shackles of this realm, Brook felt a great surge of motivation.

Even the gods of the Underworld were not invincible!

He continued searching, trying to sense a way back to the One Piece world.

...

Not long ago, in the New World's sky island.

A man shrouded in dark energy stared at an orange Devil Fruit shaped like a skull, his expression gloomy.

"So the Revive Revive clone really died after all?"

Dark Brook could not believe it.

Another one of his souls had perished in the Underworld.

Had the Underworld clone and Imu both died at the hands of the gods of hell?

The fact that there had been no news for almost half a year had already made Dark Brook anxious.

He never expected that Morgans, his adopted son who had inherited the title of Big News, would actually find the Yomi Yomi no Mi and deliver it to him.

Why did this happen?

Was he destined to be trapped in the One Piece world for the rest of his life?

Dark Brook muttered in frustration.

Although he had now become the ruler of the world, he was still unwilling to spend his life confined to the One Piece world.

More importantly, he had already witnessed the existence of the gods of hell.

It was like a blind man regaining his sight.

Once he had seen the beauty of color, he could no longer return to that dark world.

He could have endured the darkness if he had never seen the light.

Brook now knew that a higher world existed, but he was powerless to discover that his path had been cut off.

"No! I have to find a way to split my soul again! Then I'll eat the Yomi Yomi no Mi and explore hell myself!"

Dark Brook roared in anger, his frenzied Conqueror's Haki spreading across the entire New World sky island.

After that, Vegapunk, Dr. Kureha, Marshall D. Tim, and the others immediately put aside all their experimental research and joined the highest-level project, splitting the soul and eating a second Devil Fruit.

...

Back to the present.

East Blue.

A golden spaceship was constantly sailing through the sky.

"Sister Kanna, ever since Father found the Yomi Yomi no Mi, he's been unhappy. His temper has become a little irritable too."

"He's already handed the entire task of conquering the world to Uncle Shiki and Brother Hades."

"Now that the war in East Blue is over, let's hurry back and spend more time with Father Emperor!"

The third princess, Shana, spoke to the eldest princess, Kanna.

She and her siblings were not as warlike as the princes. Now, they only wanted to stay by their father's side, since he had lost his way back to the Underworld.

In the final battle, Brook's Yomi clone and Imu had perished together, causing Brook's strength to decline.

However, after resting for several weeks, Brook quickly displayed his terrifying power to the world once again through the Dark-Dark Fruit.

Moreover, after defeating Imu, Brook's Conqueror's Haki had finally reached its peak.

Even without the Dark-Dark Fruit, he could still suppress those people.

Most of the countries along the Grand Line had already been conquered by Brook and his crew.

But after Morgans found the Yomi Yomi no Mi, Brook completely abandoned the idea of personally conquering the world and handed everything to his sons and subordinates.

He then joined Vegapunk and the other scientists in another experiment involving the power of two Devil Fruits.

However, splitting the soul this time was many times more difficult than before, making Brook more and more irritable.

Now, the descendants and students of the second generation of hell had basically swept through the countries of East Blue and brought them all under the Universal Government's control.

South Blue had likely been mostly subdued by Shiki's air fleet, and the remaining countries along the Grand Line had probably been occupied by Kaido and his crew.

Meanwhile, Linlin, Redfield, and Newgate, those monsters, were either suppressing the New World or establishing the newest Universal Government on Mary Geoise atop the Red Line.

"The Yomi Yomi no Mi is connected to Father's dream of exploring the Underworld. You must never say anything about giving up in the future!"

Princess Kanna warned her younger siblings.

She had once been beaten by Brook because Kozuki Oden had said something like that.

"Understood!"

The second-generation hell descendants immediately answered.

Their golden spaceship quickly left East Blue, crossed the Calm Belt, entered the Grand Line, and returned to the New World.

Along the way, they could see Linlin and Stussy on the Red Line, leading their people in building the royal palace complex that would belong to the Brook family.

-------------

Inside the laboratory on the New World sky island.

Marshall D. Teach, the man who possessed three Devil Fruits, had already been studied for a long time.

Unfortunately, he was truly unique. His three souls had mutated while he was still an embryo, so his case did not offer much value for Brook's current research.

Unless the goal was to cultivate another three-soul mutant, Teach's body was not useful.

What Brook needed now was not to create a soul from scratch, but to split his own soul.

However, he was now the strongest man in the world. His soul was terrifyingly powerful, which made soul separation even harder.

The first split had only happened because Brook himself was originally formed from the fusion of two souls.

After that, Dr. Kureha had used the Ope Ope no Mi to accelerate the separation.

But less than a year had passed. Kureha's Ope Ope no Mi still had not developed to the point where it could split Brook's soul again.

Inside the laboratory, Dark Brook held the Yomi Yomi no Mi in his hand, his expression silent.

If there was still no progress, then he could only remain in this world and become a carefree emperor.

Perhaps he really had become too obsessed.

Recently, he had forgotten to connect with his women and children. Even his subordinates seemed to fear him more and more.

"Alas. Forget it. This is fate."

"Then I'll enjoy this world properly."

"Because of this damned Yomi Yomi no Mi, I couldn't even personally finish my great cause of unification."

"The world should already be unified by now, right? The Four Seas and the Grand Line should all be under the control of the new Universal Government, shouldn't they?"

Several months later, Dark Brook finally felt somewhat relieved while holding the Yomi Yomi no Mi.

He walked out of the laboratory, ready to embrace his new life as King of the World.

He stood beneath the sunlight of Ballon Island and glanced at the Yomi Yomi no Mi one last time before shaking his head helplessly.

"Father, you finally came out!" two voices shouted.

"Teacher!" four more voices cried out.

The sixth prince, Nika, and the fifth princess, Kikyo, rushed over with their juniors, Boa Hancock, Nico Robin, Yamato, and Inosuke.

Since the world war had broken out, and especially after Brook obtained the Yomi Yomi no Mi, he had not taught them for almost a year.

They had rarely even seen this ruler of the world.

"Yes, I'm out."

Brook dispersed the dark aura and overwhelming pressure around him. With a gentle smile, he picked up his ten-year-old fifth daughter, Kikyo.

Hancock was thirteen. Robin was twelve. Nika, Yamato, and Inosuke were all ten years old.

"Father, did your research succeed?"

Kikyo hugged Brook's neck and asked softly.

During the period when Brook had been obsessed with his research, even his children had not dared to easily provoke their irritable father.

"No. But I won't be spending every day in the laboratory anymore."

Brook gently stroked his daughter's jet-black hair and said, "Since I can't explore hell for now, I'll enjoy the human world instead. With pure gold, I don't have to fear losing immortality just because I lost the Yomi Yomi no Mi's power."

"That's great! Teacher, my Armament Haki is almost awakened! Please help me strengthen it!"

Seeing that Brook's mood had improved, Boa Hancock immediately came forward and hugged his arm, speaking in a slightly spoiled tone.

"Alright, alright. I'll give all of you special training over the next few days."

Brook rubbed Hancock's hair and smiled.

This was life.

If he stayed cooped up in the laboratory every day, waiting for research results that might never come, he would really go mad.

"Yay!"

The children cheered excitedly.

Their gentle father and teacher had returned.

Brook was just about to bring the little ones to the training ground when he suddenly felt the Yomi Yomi no Mi in his pocket vibrate and heat up.

He immediately put Kikyo down and took out the fruit.

"Father! The Revive Fruit is glowing! And there's a frightened voice inside it!"

Nika suddenly shouted.

His Observation Haki, which allowed him to hear the voice of all things, had sensed the consciousness of a Devil Fruit roaring in terror for the first time.

"What?"

Brook immediately threw the Yomi Yomi no Mi away and moved in front of the children and students to protect them.

He was a little worried that this might be the work of the gods of hell.

Back then, even through the Gate of Death, they had been able to feel the terror of the gods of hell.

Combined with the fall of his Underworld clone, Brook naturally became much more cautious.

If the gods of hell could descend into this world through the Yomi Yomi no Mi, the consequences would be unimaginable.

At the same time, on the other side.

Brook's soul clone, who had been hiding on the Underworld Road in the Western Underworld, was extremely excited.

He had finally sensed a familiar aura from a certain world.

Without the slightest hesitation, he rushed toward it.

Inside the Underworld Temple, Jin, the Western Underworld God, twitched his eyelids.

In the end, he did not open his eyes and remained immersed in training.

Brook and the six children watched as the Yomi Yomi no Mi glowed and trembled. It was as if some great terror was about to appear.

An icy chill spread outward from the center of the fruit.

The power was so terrifying that even Brook felt it was stronger than the original hell god, Jin's form.

Dark Brook instantly grew nervous.

This power seemed to have truly surpassed his own.

"You kids, go first!"

Brook immediately activated the door wristband and opened a spatial portal, intending to send Kikyo, Hancock, Nika, and the others away.

The little ones knew they would only become burdens, so they immediately prepared to rush into the portal.

"I'm finally back!"

A sudden shout made the children shiver. Their souls seemed to freeze as they involuntarily turned toward the Yomi Yomi no Mi.

There, they saw a transparent, ghostly young man howling toward the sky.

The aura coming from that young man felt familiar, but they were certain they had never seen him before.

"You're back! Holy crap, you almost scared the soul out of me, you little bastard!"

The moment Dark Brook saw him, he burst into curses.

His children might not recognize this young man, but Brook knew him very well.

Because that was exactly what he had looked like in his previous life.

"Holy crap, you're insulting me? You ugly thing!"

"You're really hard to look at! Not handsome at all! This body should just be thrown away!"

The soul clone immediately started cursing back.

He could not stand Brook's current ugly appearance, because he had been handsome for so long in the Naruto world.

"You think I want to be ugly? I want to be handsome too!"

Dark Brook shouted angrily.

Over the years, he had been practicing Life Return, constantly reshaping himself toward his former appearance while slowly letting his women and children get used to the change.

He had even asked Dr. Kureha to use the Ope Ope no Mi to make him more handsome.

Unfortunately, he still could not compare to the face he had in his previous life.

Seeing Brook and the ghostly young man arguing like two shrews left Kikyo, Hancock, and Robin completely stunned.

Was this really the Lord Brook they respected?
