*Chapter 278: Merging with the Demon Slayer World*

"The Twelve Kizuki—no one is absent!"

"This one is Muzan, and the woman who controls the Infinity Castle!"

"She can expand the interior of a small building a hundredfold!"

"For Dressrosa, she'd be a great asset."

Kakashi brought Raijin to inspect the prison, introducing the Twelve Kizuki one by one.

Especially the Upper Moons—they were captured under special circumstances.

It didn’t take much effort to capture Muzan, so Kakashi brought him back as a reward for Raijin.

Clearly, Raijin was quite pleased with Kakashi’s speed.

With intelligence in hand, these ninjas could bring an entire country to its knees in no time.

Never underestimate the power of ninjas!

And Kakashi’s skills were far from limited to that!

These were just basic ninja techniques.

"Did you get the formula out of him yet? Orochimaru would be very interested in it, right?"

"That formula is the last piece Orochimaru needs for his immortality. He won't give it up so easily."

Raijin looked at the now exhausted Muzan lying there.

He wasn’t interested in Muzan himself, only the formula for the potion that Muzan had.

A single potion that could turn an ordinary person into a grotesque monster capable of living for a thousand years.

If this potion made it into the New World, it would sell like hotcakes.

As for what would happen to the pirates in the New World, Raijin didn’t care much.

"Orochimaru’s already got the Yamanaka Clan working on it. All of Muzan’s knowledge has been extracted from his brain."

"As for the Blue Spider Lily, we’ve already found it. Soon, we’ll be able to create our own immortal monsters."

Kakashi’s lips curled into a sinister smile as he spoke. But if they succeeded, it could be disastrous for the world.

The seas might soon be plagued by terrifying, immortal monsters.

But Dressrosa had a way to counter them.

Eventually, all these monsters would be under their control.

Of course!

Kakashi didn’t think Raijin would need such things.

After all, Raijin had already mastered the Sharingan to its limit.

According to him, he was very close to reaching the power of the Sage of Six Paths.

Once he reached that level, these immortal monsters would be nothing more than a nuisance.

"What?"

Muzan, bound and lying in his cell, heard Kakashi's words.

Though he no longer had his previous elegance, he still carried the air of a progenitor demon.

For a thousand years, he had sought the Blue Spider Lily. With it, he would be immune to sunlight and grow even stronger.

But after all that time, he hadn’t found a single trace of it.

And now, these people knew where it was?

"It blooms in the daylight. Of course, you demons wouldn’t know where to find it."

Kakashi smirked. It went against the nature of demons.

And Muzan had always looked down on humans. He never developed human forces, which is why, after a thousand years, he hadn’t even seen a trace of the flower.

“Damn it!”

Muzan's face twisted in anger, but he could only curse.

There was nothing more he could do.

The two in front of him were far stronger than him.

Kakashi alone could fry his entire body with a single touch.

And the other one hadn’t even lifted a finger, yet just one glance from him made Muzan feel as though a mountain was pressing down on him.

"Alright! Take the Upper and Lower Moons and set up an arena for evening battles! Let them fight there."

"Dressrosa could use this kind of entertainment. It’ll stimulate the economy."

"As for the progenitor demon, if he’s no longer useful, just throw him into the sun."

To Raijin, Muzan’s only remaining value was the potion formula.

But since Orochimaru had already taken care of that, Muzan was no longer of any use.

"Understood!"

Kakashi nodded. He had been wondering what to do with the Twelve Kizuki.

Raijin’s idea of using them in an arena was perfect—it would also serve as great advertising for Dressrosa.

"We’ll stay here for another two weeks. It’ll take that long for Minato to move the supplies."

"And we’ll need time to populate the sky fortress. Kakashi, in the meantime, go select members from the Demon Slayer Corps."

"Just as we discussed before, invite the talented ones to join Dressrosa."

"As for the rest, handle them as you see fit."

Raijin pondered. The demon situation had been handled.

But the system indicated it would take another two weeks for the fusion to be complete.

Once the fusion with the Pure Land was successful, his power would double.

It would accelerate the awakening of the Rinnegan!

And his eye techniques would become connected to these other worlds.

Naturally, that would include Kamui and the River Styx.

Raijin was already looking forward to mastering his eye techniques.

Once they succeeded, he could challenge the Sage of Six Paths himself.

"Got it! I’ll take care of it."

Kakashi nodded.

He knew exactly who in the Demon Slayer Corps had potential.

Like the new trio—Tanjiro, and the wild boar guy.

They were among the best and could be taken to the seas.

There were other promising members in the Demon Slayer Corps too, and Kakashi had the freedom to pick whoever he wanted.

He could select plenty of talented individuals for training.

With focused nurturing, some of them could even become pillars of Dressrosa.

Kakashi stroked his chin.

It seemed the next generation of Dressrosa was going to be incredibly strong.

He wondered if the pirates, the Navy, and others across the sea would be able to stand up to them.

Oh well!

They were destined to replace the World Government someday.

For now, they were just gathering strength!

Otherwise, the World Government wouldn’t have stayed in power for so long.

Still...

Would his Sharingan evolve into the Rinnegan?

Two weeks passed!

The underworlds of both worlds had fully merged.

When that connection was made, powerful beings felt something inexplicable.

But the sensation wasn’t very clear.

They only felt that the world had become more powerful.

At the same time, new Devil Fruits began to appear across the seas.

They were born from the myths and legends of the Demon Slayer world, transformed into Devil Fruits in this one.

Raijin sat on the throne in the sky fortress, feeling the chakra within him expand continuously.

In an instant, his chakra surged once again.

Raijin had gathered the chakras of Indra and Asura.

His chakra was already immense, but now it was even more powerful.

But unfortunately, despite all that, his Rinnegan still hadn’t appeared.

Raijin pondered. Why couldn’t the Uchiha bloodline evolve on its own?

Why did it need to be tied to the Otsutsuki bloodline?

Raijin felt that he could isolate and strengthen the Uchiha bloodline.

With him here, the Uchiha bloodline could become even stronger.

But it was a difficult task.

Raijin wondered if he could get some rewards from the system.

"There are now over 10,000 people in the fortress, including nine Demon Slayer members who agreed to join us."

"These are the people we need. One of them is a girl who had been turned into a demon but has now returned to human form."

"In addition, the prison now holds about fifty demons, including the Twelve Kizuki!"

"As for the progenitor demon, Kakashi took him for experiments. He was turned back into a human and then killed by Orochimaru."

"Our ninjas have all landed, and Zephyr is selecting a few talented ones to take on as disciples."

"Oh, and Shinobu, after learning about Dressrosa’s customs, has expressed interest in becoming one of the queens."

Kakashi had a strange look on his face.

But he didn’t say anything; after all, Butterfly Shinobi’s appearance was indeed quite good.

Though she seemed a bit scheming, her abilities were still impressive.

She managed Butterfly House well in all aspects.

She was someone Kakashi approved of.

As for becoming a princess, it seemed that this woman couldn’t stop worrying about the girls who had been taken away.

Knowing their future fate, she was planning to find a better path for these girls.

Butterfly Shinobi also had her own plans; she wanted to become a central figure in Dressrosa.

She knew that if she only became a student of Zephyr, she would only remain in the middle ranks.

Dressrosa was filled with powerful individuals, and the ninjas there were like ghosts.

Even with good talent, they were no match for these monsters.

If she wanted to help those girls, she didn't know how many years she would have to climb to be able to.

So, Butterfly Shinobi decided to take a shortcut.

After all, the ancient ghost was already dead, and their mission was complete.

There was no need to dwell on it anymore.

"Alright, what else?"

Raijin didn’t have many thoughts about it and continued asking.

"Minato-sensei and Raikage have already mined most of the extractable ore in this country, using a lot of manpower."

"Although many people died from exhaustion, we’ve still had a great harvest. I’ve stored most of it in my Kamui dimension."

"We also dug up quite a bit of the ore for the Nichirin Blade! This trip was very fruitful."

Kakashi rubbed his white hair, looking a bit lazy.

But he was clearly very excited!

The biggest gain was that they acquired this ghost's potion.

It would become the most powerful force in Dressrosa.

"Let’s go then! There's no need to stay here any longer."

Raijin, after learning about their gains, showed a smile.

After all, this world was quite poor, which was understandable.

Who knows how many years it would take for them to catch up with the technology in the Naruto world.

"Alright! Everyone is already on the floating fortress, ready to leave anytime!"

Kakashi nodded. Almost everyone was here.

With a thought, Raijin opened a portal in front of him.

His Mangekyō Sharingan spun continuously, gradually enveloping the entire floating fortress.

In the next moment, they entered the Kamui dimension.

Raijin stepped into the vortex!

As soon as he walked in, a faint salty breeze hit him.

Finally, they were back!

Dressrosa seemed to be at peace, with nothing happening.

After being gone for over a month, there had been some trouble on the seas.

But it had nothing to do with Dressrosa.

Shikaku Nara had maintained steady development without causing any issues.

When Raijin returned, Shikaku let out a sigh of relief.

"You need to understand, once you drink this, there’s no turning back."

"You’ll never be able to appear in daylight again, living your life in darkness."

"Your dietary habits might change, and you could become a target for everyone on the seas."

"If you’re not sure, you can wait. The Beast Pirates still have other people who can try it first."

Orochimaru licked his lips, looking at the large man in front of him.

He held a potion in his hand, shaking it as he spoke.

The potion seemed to carry a tempting power, and Jack couldn’t help but fall into it.

Jack hesitated for a moment, then his face twisted with determination.

If he didn’t drink it, he’d remain at the bottom of the Beast Pirates.

But if he drank it now, he could rise to the top, just under Kaido.

However, the downside of not being able to appear in daylight...

"Haven’t you found a way to solve this side effect?"

Jack held up two fingers and finally took the potion.

He already knew the outcome, but this was the result of their efforts.

The Beast Pirates and Big Mom Pirates each got one.

It would be extremely difficult to get more later.

Dressrosa had no intention of spreading this widely.

But Jack knew that it had some inherent spreadability.

"Even Devil Fruits have side effects; this thing can’t be avoided."

"But some people have reportedly overcome their fear of the sun and stood under it."

"You can give it a try when the time comes."

Orochimaru licked his tongue and shrugged.

But his eyes remained fixed on Jack.

Jack was his first test subject.

He wanted to see Jack's transformation firsthand.

"Heh."

Jack sneered, dismissing Orochimaru’s words as nonsense.

Try and die?

Pop!

He uncorked the bottle!

Jack downed the unknown liquid in one gulp.

Then, he sat down, waiting for the effects to kick in.

After about half an hour, Jack suddenly let out a roar.

"Roar!"

He grew two meters taller, his muscles bulging even more.

His eyes glowed with a terrifying red light, and his body exuded an overwhelming aura.

His gaze became predatory, as if the people in front of him were prey.
