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

"What an arrogant name! How could Kaido allow someone to have such a name?"

"Hey kid, who are you, and what brings you here?"

"."

The prisoners in the nearby cells all looked at the person who shouted, and they also recognized him.

Jinpei.

This one of the Seven Warlords of the Sea was also imprisoned in Infinite Hell.

Naraku was also drawn by Jinbe's shouts.

However, Naraku only glanced at this Shichibukai before looking away.

"Enough of the unnecessary pleasantries, I now need your help in my cultivation!"

A little praise was enough; Naraku clearly had little interest in exchanging words. He smiled and gestured with his hands raised.

boom! ! !

The violent magical power transformed into countless illusory dragons, forcefully smashing through the bars and rushing into every cell.

"You bastard, get out of my way!"

"Damn it, if it weren't for the Seastone handcuffs, I would never have fallen!"

"Do not!!!"

"."

The dragons that rushed into the prison opened their mouths and swallowed the prisoners inside.

Faced with such an encounter, how could so many unruly madmen allow themselves to be slaughtered? They fought back fiercely.

But a pity.

It's like being unable to escape from a cage.

Although the prisoners in the Infinite Hell are far stronger than those in the upper levels, the sea stone handcuffs and various other restraining methods render them powerless to resist.

Whether it's Red Earl, Jinbe, or Crocodile.

Even someone like Barrett, who is comparable to the Four Emperors.

None of them could escape; they were all swallowed by the magical dragon and then strangled into a bloodbath.

One stream of Devil Fruit energy after another was drawn in, sealed, and sent into the inner space.

The converging blood condensed into a giant blood sphere in front of Naraku.

Sensing the rich aura of flesh and blood contained within the blood sphere, Naraku smiled.

Infinite Hell is Infinite Hell.

Although the number of prisoners held here is the smallest among all floors, their quality is the highest.

The blood spheres that are currently gathering contain even more exaggerated amounts of flesh and blood energy than the elephant spirit.

Sitting cross-legged in mid-air.

Naraku placed his hands on the giant blood sphere and immediately began refining it.

A torrent of blood and flesh energy surged into his body, causing the "Blood Soul Technique" to advance rapidly.

The blood cells shrank slowly at a rate visible to the naked eye.

It is unknown how long it lasted, but it eventually disappeared completely.

boom! ! !

A domineering aura suddenly emanated from Naraku, like a tangible wave of air, causing ripples to spread through the surrounding void.

"Almost there, just a little bit more and we're about to break through."

Naraku, having finished his refining process, landed on the ground.

He felt his physique improve once again, and his heart was filled with anticipation.

The hunt in Impel Down not only brought back a large number of Devil Fruits, but also pushed the "Blood Magic" a step further.

We are now just one step away from achieving a minor success.

Naraku looked up at the ceiling.

boom! !

With a surge of magical power, Naraku was instantly propelled into the sky and crashed into the ceiling.

Debris exploded.

In one impact, the ceiling was pierced through.

However, Naraku did not appear on the fifth underground floor, but rather in the gap between the fifth and sixth underground floors, which is the secret underground floor 5.5.

"what happened?"

"That was terrifying! Why did the ground suddenly explode?"

"Wait, someone's in mid-air. They crashed through the floorboards."

"."

The space on the 5.5th underground floor is filled with bizarre-looking transvestites.

Naraku, standing in mid-air, looked down at these transvestites and immediately spotted Ivankov and Imazuna, two Revolutionary Army cadres, as well as Buggy and von Clay, former members of Baroque Works.

His eyes narrowed.

A violent surge of magical power swept out once more, like a fishing net, capturing everyone present.

His body exploded.

Users with Devil Fruit powers absorb the energy from the fruits, while those without powers are directly reduced to blood.

In the face of such a vast difference in dimensionality, even those on the 5.5th underground level, without any restraints, would find it difficult to resist Naraku's suppression.

In just a short while.

The Devil Fruit's energy is sealed, and the essence of flesh and blood is refined.

Bang!

Suddenly, the door of a building in the distance was pushed open, and a figure wrapped in bandages rushed out.

"Little Eva, Little Feng Feng, I'm recovered!!!"

Having been healed by the Hormone-Hormone Fruit's power, Luffy ran out of the house with a big smile, intending to tell everyone that he had succeeded. However, upon seeing the scene outside, he quickly slammed on the brakes.

Where is everyone?

His smile was replaced by astonishment. Luffy scratched his head, looking around in confusion, and finally spotted Naraku standing in mid-air in the distance.

Naraku also stared calmly at Luffy.

Someone has been spotted.

Even though he didn't know them, Luffy still rushed over.

"Hey, have you seen Bon Clay and the others?" Luffy was surprised that Naraku could fly, but he was more concerned about the whereabouts of the others.

It landed and descended.

Naraku landed smoothly on the ground.

"Do you really want to see them? I can take you there."

"That's great, thank you—"

His face lit up with joy, but before he could finish speaking, Luffy's expression froze.

Naraku, expressionless, gripped the other's face.

Without giving him any extra reaction, he instantly used his magic to suppress Luffy, the protagonist, into a bloody mist.

As it turns out, the protagonist's halo is useless against Naraku.

The blood flow was transformed into the essence of flesh and blood, and the rubber hidden in Luffy's body—no, it should be said that the Nika Fruit was immediately extracted.

They charged left and right.

The energy of the Nika Fruit, which was absorbed by magic, exhibited a different behavior than that of other fruits.

It seemed to possess self-awareness, and at the same time, it had an extremely strong resistance, wanting to break free from the shackles of magic.

Upon seeing this, Naraku actually laughed.

Its exceptional performance is truly remarkable; this proves that the Nika Fruit lives up to its status as a true protagonist.

Release more magic power.

The struggle of the Nika Fruit was to no avail; it was calmly sealed into a jewel by Naraku and sent into his inner space.

"Oh? The last batch of prey has come to us willingly."

With a sudden thought, Naraku looked up and his gaze seemed to pass through the building, revealing a view of the sea below.

With a light laugh, Naraku raised his hand and stepped into the opened spatial vortex.
