Research Speculation on the Void and the Grim Reaper

"Boom." The earth bomb hit Hollow's body, only causing his body to pause for a few seconds. The power was extremely weak.

"Ninjutsu's power has suddenly decreased." Naruto watched this scene quietly, and he had a rough idea of some experimental data in his heart.

The Jonin who had become Hollow, had a certain level of improvement in his strength, but he would lose his mind and be dominated by savage killing.

The Jonin who had successfully transformed into Shinigami, would receive a huge decrease in strength.

Because Chakra had just merged with Reiatsu, the amount of Reiatsu that he had activated was limited, so his physical strength would decrease.

"Chi." In his line of sight, Hollow's claw pierced through Shinigami and Jonin's chest and pulled out. Shinigami Jonin fell to the ground, his life and death unknown.

Hollow bent down and forcefully swallowed Reiatsu, who was overflowing from Shinigami's body.

Naruto adjusted his glasses, his eyes flashing.

Hollow has a natural hostility towards Shinigami, so after Hollowfication, he directly attacks Shinigami. He had no intention of attacking me at all. After killing the other party, he began to devour Shinigami to increase his strength.

"This is in line with the Hollow that Mr. Aizen mentioned. Hollow will continue to hunt and kill his own kind or Shinigami to increase his strength by devouring the other party. From then on, he will break through the boundary and evolve to a higher level."

Hollow is divided into two levels: ordinary Hollow and Huge Hollow.

Ordinary Hollow is converted from a human.

A huge Hollow is usually an ordinary Hollow that swallows hundreds of Hollows.

However, in Ninja's world, the Chakra in Ninja's body met the conditions of ordinary Hollow's evolution, so the Hollow born was Huge Hollow.

Huge Hollow was divided into three levels.

The first was the most basic level, Gillian.

They had black outer bodies and white colored bone masks. They were huge but slow in movement. They did not have any intelligence and only attacked and devoured their kind like beasts.

When they devoured enough spirit particles, they would transform into the Adjuchas.

The second level is the Adjuchas.

The Adjuchas would have beast armor, and they would have a high IQ and great destructive power. Their strength was probably several times stronger than the Gillian's.

They would have the ability to command a large group of Gillian, but even so, they would still need to rely on devouring spirits to evolve.

There were two evolutions of Adjuchas: One, when one's strength reached a bottleneck, if one could not continue to increase his strength, it would always be Adjuchas; two, break through the bottleneck, and when his strength rose to a new level, it would become Hollow, the third level, Vatso Lorde.

The third level is Vatso Lorde.

Vatso Lorde was the highest level Hollow. Interestingly, they had the same size as humans, which meant that their strength was more concentrated.

Aizen did not elaborate on the specific abilities, because in his experiments, there was no Vatso Lorde.

Therefore, this level was still in the trial.

However, from past research, one could conclude.

The higher the grade of Hollow, the more he would possess a body and reason that was close to that of a human. After liberation, the changes to his body would be even smaller.

According to what Aizen said.

Shinigami could be Hollowfication, and Hollow could also have Zanpakutō.

Therefore, the research that Naruto and Orochimaru would conduct would not only be targeted at Shinigami and Hollow.

However, the biggest difference between Shinigami and Hollow was.

Shinigami would often remember the memories of his life, but Hollow would forget them all.

Since he had evolved from devouring his kind, Hollow's personality would be more cruel.

It was just that he did not know if these conclusions could be used for humans.

Naruto frowned and muttered to himself,

"This Jonin who transformed into Shinigami still has memories of his past life. It's just that he is too unfamiliar with Reiatsu's control and is in the same situation as Haku."

"Hollow has completely lost his mind. He only has the instinct to devour."

"However, there are too few experimental cases. We can't directly conclude. We need to increase the number of experiments." Naruto once again injected Reiatsu into the other souls of Jonin.

"Roar." At this time, Hollow, who had already swallowed the mark, looked at Naruto with bloodthirsty eyes.

"Oh? You want to kill me?" Naruto laughed with disdain.

"Roar." Hollow ran towards Naruto.

His eyes were filled with bloodlust.

"Other than Jonin's strength, it is indeed very troublesome. However, his IQ is too low." Naruto moved and disappeared from Hollow's sight.

"With Kyōka Suigetsu, we can easily leave the battlefield." Naruto took the opportunity to inject Reiatsu into the other souls of Jonin. Then, he hid in the dark and quietly observed the reaction of the experimental materials.

Soon, all five of Jonin appeared in white fog.

The last four souls of Jonin turned into Hollow, and only one successfully turned into Shinigami.

And the soul that turned into Shinigami was undoubtedly torn apart.

The remaining Hollow also began to kill each other.

The great power caused was eye-catching.

"It seems that the amount of chakra will affect the success rate of conversion, and the success rate of Jonin's conversion is significantly higher." Naruto tapped his fingertips and quickly disappeared into place. He fled in Konoha's direction, constantly transforming his soul.

However, he still stopped a little and scattered his soul to reform his soul. Otherwise, Konoha might be destroyed by Hollow.

When Reiatsu had almost used up half of his body, Naruto stopped and looked meaningfully in the direction of Jiraiya and Konoha's Jonin.

"That's it. Today is a very fulfilling day." Naruto slowly walked towards the arena, shuttling back and forth between Ninja and the others.

Strangely, no matter if it was Ninja, Hollow, or Shinigami, they seemed to have not seen Naruto at all. All kinds of Ninjutsu slid past Naruto and landed on the enemy, causing an explosion.

Hollow was not to be outdone. He shot out Hollow Flash and directly destroyed a large number of houses.

The entire Konoha began to emit black smoke.

Naruto also noticed that Ninja who had been hiding for a long time, finally showed up.

Although Danzo wanted to become Hokage and planned to let Sandaime die, he would not stand by when Konoha encountered a disaster.

"At this time, Konoha is the most united and ridiculous." Naruto chuckled.

Light and fire overflowed. As smoke and dust filled the air, he wore a white robe and walked past with calm and composed steps. Behind him were all kinds of explosions from Ninjutsu and Hollow.

It formed a wonderful scene.

...

On the other side, Jiraiya had already used Ninjutsu to easily deal with the two giant snakes.

Chakra was still full of energy.

This kind of battle was not even a warm-up for him.

His eyes quickly fell on Shukaku in the distance.

He was ready to suppress Shukaku.

Konoha was not a place where the Biju could behave as they pleased!

"What kind of monster is this!"

"What a terrifying fellow!"

"Could it be a tailed beast?"

However, before Jiraiya could make a move, the distant roars, and screams attracted his attention.

Jiraiya looked over and was stunned to find a few monsters with white bone masks fighting with Ninja.

Their bodies were restrained, their claws were sharp, and their bodies were emitting the aura of death.

Its mouth could shoot out a skill similar to a bullet, which was powerful enough to instantly destroy a house.

Konoha was already riddled with holes under the attack of these Hollows.

There were ruins and broken limbs everywhere.

"What are these things?" Jiraiya's expression became extremely ugly.

"Kuchiyose no Jutsu!" He formed a seal with both hands and slammed it hard against the ground.

Smoke immediately shrouded the air.
