I use the ninja world to help me cultivate immortality

This [Mangekyō Sharingan] evolved from one of the [Three Magatama Sharingan] that he had been nurturing with his true energy.

Because it was the second [Mangekyō Sharingan], in order to distinguish it, he named the one of Uchiha Kagami [Mangekyō Sharingan No. 1], and now this one is [Mangekyō Sharingan No. 2].

During the research, Naraku found that [Mangekyō Sharingan No. 2] did not show any abnormalities due to the different evolution methods.

In addition to the fact that the basic pupil power was greatly improved compared to the [Three Magatama Sharingan], the development of pupil skills was also very normal.

[Mangekyō Sharingan No. 2] is different from [Mangekyō Sharingan No. 1]. The pupil skills developed are not the extremely rare two-in-one pupil skills such as "Kami" and "Great Property", but the common double pupil skills.

The pupil skills developed by [Mangekyō Sharingan No. 2] are "Tsukuyomi" and "Kagutsuchi-no-Mikoto".

The Sharingan is the eye that reflects the soul.

Normal evolution to Mangekyō, the eye technique that is bred is often affected by the thoughts and ideas during the evolution.

For example, Uchiha Sasuke, who longs for power, bred "Amaterasu" and "Kagutsuchi-no-Mikoto", two eye techniques that are good at fighting.

Uchiha Obito, because he wanted to escape from reality, bred "Kamui" that leads to another world.

Naraku's situation is quite special.

One is that he is not a member of the Uchiha clan, the second is that the Sharingan has been refined into a magic weapon, and the third is that the evolution of the Mangekyō is not emotionally stimulated, but nurtured by true energy.

This makes the eye technique that is bred, rather than being affected by his thoughts, it is better to say that it has a considerable degree of randomness.

Of course, no matter what, as long as the eye technique is fine, it is enough for Naraku.

"'Tsukuyomi' and 'Kagutsuchi-no-Mikoto'?"

As for the two eye techniques bred by [Mangekyō Sharingan No. 2], they are relatively familiar eye techniques because they appear in the original plot.

'Tsukuyomi' is an illusion-type eye technique.

As long as the eyes make contact, this eye technique can pull the enemy's spirit into the illusion space where all factors including time, place, quality, etc. are controlled by the caster.

The most important thing is that no matter how long you stay in the illusion space, it is actually just a moment in the outside world.

This eye technique can be said to be quite practical whether it is used for fighting or for interrogating intelligence.

Then there is "Kagutsuchi no Mikoto".

In the original plot, Uchiha Sasuke, who bred this eye technique, cooperated with another eye technique, Amaterasu's fire.

But according to the eye technique information obtained by Naraku at this moment.

"Kagutsuchi no Mikoto" is not only used in conjunction with "Amaterasu", its essence is just a control-type eye technique.

It can control Amaterasu's fire, and it can also control energy including chakra.

For example, if chakra can be controlled by "Kagutsuchi no Mikoto", people's control over chakra can be greatly improved.

"This [Mangekyō Sharingan] is quite suitable for Nono!"

After learning about the eye technique of [No. 2 Mangekyō Sharingan], Naraku thought thoughtfully.

One of the fundamentals of "supernatural power" is the control of chakra.

If Nono can get the blessing of "Kagutsuchi-no-Mikoto", even if "Tsukuyomi" and the basic eye power of Mangekyō are not counted, it will be enough to greatly improve her "supernatural power".

Of course, Naraku still needs to conduct more detailed tests on whether [No. 2 Mangekyō Sharingan] will be given to Nono.

For example, he wants to confirm whether two Mangekyō that are not blood relatives can really not be fused into the Eternal Mangekyō.

He also wants to see if there are other differences between the two Mangekyō besides the eye technique, and whether more information about Mangekyō can be studied.

"Is it really impossible?"

On the ninth floor of the Xingchen Building, Naraku removed the True Fire Cauldron in front of him and took the two [Mangekyō Sharingan] that flew out into his hands.

Looking at the two [Mangekyo Sharingan] in his hand, Naraku's face showed a look of pity.

Just now, he tried to fuse the two [Mangekyo Sharingan] with the method of refining equipment.

It's just that the fusion is possible, but the fusion method and fusion effect are not what he wants.

The fusion effect that Naraku wants is naturally to fuse the two [Mangekyo Sharingan] into a higher level [Eternal Mangekyō Sharingan].

But in the fusion just now, he clearly felt that the two [Mangekyo Sharingan] had a certain repulsion.

If he forced the fusion, although it would not destroy the two [Mangekyo Sharingan], at most he would get a [Mangekyo Sharingan] with stronger pupil power.

If the fusion effect of the Eternal Mangekyō Sharingan is 1+1＞2.

Then the current fusion effect is 1+1＝1.2 or 1.3.

With such a fusion effect, it is better to keep the two [Mangekyo Sharingan].

If it cannot be fused into the Eternal Mangekyō Sharingan, then for Naraku, the fusion is a failure.

Thinking of the research on the two [Mangekyō Sharingan] these days, Naraku couldn't help but fall into deep thought.

Although they are from the same clan, the awakened Sharingan of different people is obviously different, just like blood type.

And if you want to fuse into the Eternal Mangekyō Sharingan, you must have a Mangekyō Sharingan with the same blood type.

"But if you fuse it in the way of refining magic weapons, there is still hope that so many [Mangekyō Sharingan] can fuse into the Eternal Mangekyō!" Naraku thought.

Quantitative change leads to qualitative change.

Not to mention Otsutsuki Hagoromo, even Indra, when he awakened the Mangekyō, he directly possessed the characteristics of the Eternal Mangekyō.

And the Uchiha clan, which was bred by Indra.

The defects of the Mangekyō Sharingan are more like the result of the dilution of bloodline after generations of inheritance.

Therefore, as long as the bloodline can be purified, there is a chance of reversion.

The fusion of the Mangekyō Sharingan is one of the ways of reversion.

The fusion of the Mangekyō Sharingan of blood relatives has the best reversion effect.

The fusion of the Mangekyō Sharingan of non-blood relatives, although not as good as the former, is also on the road of reversion.

So if there are enough Mangekyō Sharingan fusions, there is still a chance to evolve into the Eternal Mangekyō.

Of course, Naraku's refining method is much more sophisticated than the rough fusion of transplanted eyes.

In addition to being safer, the fusion efficiency is also better.

According to Naraku's rough estimate, with the refining method, up to four [Mangekyō Sharingan] have the opportunity to fuse into the Eternal Mangekyō.

He now has ten [Three Magatama Sharingan] in nurturing.

One of them is the same as the [No. 2 Mangekyō Sharingan], which is at the level of three magatama in the early stage.

It can be seen that he only needs to wait patiently, and more [Mangekyō Sharingan] will come soon.

"Since it is temporarily impossible to fuse the Eternal Mangekyō, then this [No. 2 Mangekyō Sharingan] will be given to Nono!"

After these days of research, Naraku has collected more information about the Mangekyō.

One more [Mangekyō Sharingan] will not greatly enhance his strength.

So instead of keeping it idle in his hands, it is better to give it to Nono to use it.

Anyway, he can take it back at any time when he needs it.
