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

Whether it was Sunagakure or Kumogakure, both groups left Hoshigakure with smiles on their faces, happily returning to their respective villages.

The ninth floor of Xingying Tower.

When Sunagakure and Kumogakure came to divide the spoils, Naraku was not idle.

He sat cross-legged amidst numerous shadow clones of true energy.

Naraku was refining a pair of Byakugan eyes, as well as Uchiha Kagami's Mangekyou Sharingan.

Let's leave the Mangekyou Sharingan aside for now.

Regarding the white eye.

The captured Hyuga clansmen have not yet been dealt with.

But Naraku had already earned a full nineteen pairs of Byakugan.

Those eye rolls.

Some of them were eyes taken by Hyuga Hiashi through a true qi shadow clone.

Some of them are the eyes of the deceased members of the Hyuga main family.

Others were unexpected discoveries made during the raids on the Hyuga clan's territory.

Perhaps just in case, the Hyuga clan keeps multiple Byakugan within their clan grounds.

Now, all those Byakugan eyes have benefited Naraku.

"The Byakugan's potential is actually no less than that of the Sharingan. The Sharingan can evolve into the Rinnegan by supplementing the Sage Body, and the Byakugan also has the evolutionary path of the Tenseigan."

Naraku, who was manipulating the True Fire Cauldron and refining his Byakugan eyes, was silently pondering.

His interest in the White Eye stemmed not only from its strategic value, but also from its inherent potential.

Based on the Tenseigan's performance in the original storyline, it is absolutely incredibly powerful.

However, evolving from the Byakugan to the Tenseigan is also extremely difficult.

There are only two known methods.

One method is to gather a large number of Byakugan, and through quantitative change, trigger qualitative change to create a giant Tenseigan.

Another method is to use Otsutsuki chakra to nurture a pair of Byakugan with high purity.

"I wonder if my true energy can also nourish the Byakugan," Naraku pondered, focusing on the evolution of the Byakugan.

The Sharingan, refined into a magical artifact, can evolve through nurturing with true qi.

Naraku naturally had high hopes for the true warmth that would nourish his Byakugan.

If the Byakugan can be nurtured and evolved, then there is hope of obtaining the Tenseigan in the future.

"If this doesn't work, I'll have to go to the moon sometime in the future," Naraku added in his mind.

Once he's strong enough to not fear Hagoromo Otsutsuki, he definitely won't let either the Tenseigan or the Rinnegan go.

After all, Hagoromo Otsutsuki is not the final boss of this world; there is still the real Otsutsuki clan behind him.

Given the resources of the ninja world, Naraku doesn't believe he can sustain himself to become an immortal. Therefore, it's only a matter of time before he leaves the ninja world and explores the entire universe.

The ritual was a success.

The Byakugan is different from the Sharingan.

However, this was just basic refining, which was nothing more than a piece of cake for Naraku, whose weapon-refining skills were becoming increasingly proficient.

Soon, when the refining was successful, the Byakugan, like the Sharingan, merged into a single jade-like eyeball.

Naraku absorbed the Byakugan, which he intended to use as a magical artifact, into his body and attempted to nurture it with his true energy.

"No problem, the [Byakugan] is indeed a growth-type magic weapon; it can be nurtured and evolved using true energy!"

A moment later, feeling the Byakugan slowly absorbing his true energy, Naraku immediately smiled.

In a good mood, Naraku tested the Byakugan's abilities.

Unlike Nono and Natsumi, who only underwent a basic blood oath ceremony.

Naraku's ritual of recognizing a master meant that he didn't need to reveal either the Byakugan or the Sharingan when activating them.

First, it is activated with chakra.

In an instant, the Byakugan, which had merged into his body, projected its power into Naraku's eyes, giving him a new perspective.

Despite the projection of his pupil power, Naraku's eyes did not turn into white eyes.

However, from his perspective, it presents a pure white view as if the Byakugan is activated.

This perspective allowed his gaze to easily penetrate the entire Star Shadow Building, extending in all directions without any blind spots, instantly revealing things a kilometer away.

Of course, the perspective of the "White Eye" is only a structure similar to an energy body, whether it is a house or a living being, and it is not the kind that needs to be harmonized.

Otherwise, the Hyuga clan would not have survived to this day; they would have been wiped out long ago.

After experimenting with the effects of chakra on the Byakugan, Naraku then activated it with his true energy.

When true energy is channeled into the [White Eye], the field of vision expands instantly, reaching a distance of ten kilometers.

It is clear.

Compared to chakra, true qi can better activate the abilities of the Byakugan.

Naraku was not surprised by this situation, as he was already used to the difference between true qi and chakra.

After a simple experiment, Naraku began to refine the remaining Byakugan.

One by one, the Byakugan were successfully refined. After the process, Naraku gained nineteen white jade-like Byakugan.

"There's no need to rush the nurturing of the Byakugan. Afterwards, just like with the Sharingan, give one to Nonou and the others to enhance their strength."

When Naraku absorbed all the Byakugan into his body, he distributed them among himself.

While the Byakugan may not be as good as the Sharingan with three tomoe in terms of combat, in terms of insight, even the Sharingan at the Mangekyou level would have to rank behind.

If Nono and the others could obtain the Byakugan, not only would their strength increase, but their safety would also be greatly improved.

Chapter 160 Kaleidoscope Eye Technique: The Great Master

"Next up are these Mangekyou Sharingan."

After the Byakugan refinement was completed, it was naturally Uchiha Kagami's turn to refine his Mangekyou Sharingan.

Naraku retrieved the Mangekyou Sharingan from the container and once again condensed the True Fire Cauldron to begin refining the Mangekyou Sharingan.

"A kaleidoscope is a kaleidoscope; the power it contains is qualitatively different from that of a three-tomoe jewel."

During the refining process, Naraku's divine sense constantly monitored the Mangekyou Sharingan within the True Fire Cauldron.

Through insight, one can easily perceive the abundant ocular power contained within the Mangekyou Sharingan, which is composed of the ultimate Yin Release.

Naraku exclaimed in admiration, and then became even more enthusiastic about the refining process.

The Mangekyou Sharingan is a higher-level material than the Byakugan and the Three-Tomoe Sharingan, and therefore requires a longer time to refine.

After a while, the ritual finally came to an end.

When the fire in the cauldron dissipated, a scarlet jade ball with a cross-shaped pattern appeared.

This crimson jade ball with the cross pattern is the [Mangekyou Sharingan] that was refined into a magical artifact.

As the True Fire Cauldron dissipated, Naraku reached out and took the Mangekyou Sharingan into his palm.

After carefully examining the Mangekyou Sharingan in his hand and confirming that there had been no problems with the refining process, Naraku then integrated it into his body.

hum!

The Mangekyou Sharingan is just like the previous Byakugan. With Naraku's activation, the power of the eye is immediately projected into Naraku's eyes.

"Is your vision a little blurry because it has been used multiple times before, causing your eyesight to deteriorate?"

Looking around, Naraku immediately realized that his vision was extremely blurry, as if it had been pixelated.

He frowned slightly at this reaction, but wasn't particularly surprised.

He merely refined the Mangekyou Sharingan into a magical artifact, without repairing its damaged state.

After evolving the Mangekyou Sharingan, it's impossible for Uchiha Kagami not to have fought using the Mangekyou Sharingan.

Or rather, even if he hadn't used it much, since the Mangekyou Sharingan had fallen into Hiruzen Sarutobi's hands, how could the latter not have experimented with it?

Otherwise, these Mangekyou Sharingan would not have appeared in the laboratory of the Anbu base.

Upon discovering that the Mangekyou Sharingan was severely damaged, Naraku frowned slightly, but his frown quickly eased after he infused it with his true energy.

"Fortunately, it can be repaired through gentle nurturing, otherwise the value of this Mangekyou Sharingan would be greatly reduced."

The reason why Naraku's brows relaxed was precisely because of the gentle nourishment of his true energy.

Even with the Mangekyou Sharingan, true energy still has a nourishing effect.

Moreover, this nurturing effect is not only about evolution, but also about repair.

As soon as Naraku infused his true energy into the Mangekyou Sharingan, he immediately sensed that the Mangekyou Sharingan's depletion was slowly recovering.

This situation naturally put his mind at ease.
