I use the ninja world to help me cultivate immortality

It is worth mentioning the growth of the "Sky Eye".

With Senju Tobirama as the source, Konoha's research on the Sharingan and the Byakugan is really thorough, which provides Naraku with considerable convenience for the subsequent development of the "Sky Eye".

Through these research materials, such as the Byakugan, which is relatively easy to conquer, he has initially integrated the "Sky Eye".

This allows the improved "Sky Eye" to have a certain perspective and farsightedness, and the insight is also improved.

I sorted out my own situation.

Naraku still defines his overall strength as below the Six Paths.

Although his strength has been improving, he still tends to be conservative before he really fights with Otsutsuki Hagoromo.

As for how he compares with Senju Hashirama in his prime and Eternal Madara, he is still very confident.

After all, the abilities of these two people are much clearer than Otsutsuki Hagoromo.

Apart from anything else, just "Shrinking the Earth into an Inch", Naraku believes that he can at least be invincible.

"The next practice is still mainly to improve the cultivation!"

After confirming his own strength level, Naraku is very clear about the direction of future practice.

The first one must be cultivation.

Cultivation is the foundation, and supernatural powers and others are just branches and leaves derived from the trunk.

Naraku is very clear about this.

Just like during this period of time, in addition to sending people to inquire about the news of ghosts and gods, he has never stopped collecting and cultivating spiritual medicines.

Not to mention the former, the latter.

Although "Tianyi Divine Water" is still in the entry stage, compared to when it was just mastered, with steady improvement, the speed of cultivating spiritual medicines can be said to be more and more significant.

"Huh?!"

Suddenly, Naraku felt something strange coming from his body.

He thought, and his right hand, which tapped the table lightly, turned his palm upwards.

The next second, a [Three Magatama Sharingan] appeared from the palm.

Looking at the [Three Magatama Sharingan] that appeared in the palm, the three magatama inside were spinning rapidly at the speed of forming an afterimage.

With his spiritual awareness, Naraku instantly understood the situation of the [Three Magatama Sharingan].

His eyes flashed with a gleam, and he gathered his true energy without hesitation, pouring it into it continuously.

With the infusion of true energy, the three magatama in the [Three Magatama Sharingan] rotated faster, and then suddenly retracted into the central pupil.

Buzz! ! !

After a slight tremor, the three magatama retracted into the central pupil, and the central pupil actually extended a pattern like a clover.

"Mangekyo Sharingan?!"

An exclamation came from behind Naraku.

The one who exclaimed was Hinata Rinka, who was guarding behind Naraku with her sister Hinata Yuika.

After the exclamation, Hinata Rinka reacted immediately, and hurriedly bowed to Naraku in panic and said: "I'm sorry, sir, I lost my composure, please punish me!"

"Do you know the Mangekyō Sharingan?" Naraku turned his office chair and looked at Hinata Rinka with interest.

Although the Sharingan has changed after being refined into a magic weapon, its general appearance is still similar.

Especially the iconic magatama, basically anyone who knows the Sharingan can tell it apart.

"To answer your question, I was fortunate enough to learn from the historical documents recorded in the clan that the Uchiha clan's Sharingan has not only the magatama form, but also the more advanced evolutionary form of the Mangekyō!"

Seeing Naraku looking at her, Hyuga Rinka hurriedly bowed and replied.

On the side, Hyuga Yuika glanced at the 'Sharingan in Naraku's hand, and then at her sister, with a complicated look in her eyes.

Naraku was not surprised by Hyuga Rinka's answer.

The Hyuga clan and the Uchiha clan also have a long heritage, and even because they inherited the same eye technique blood limit, the two clans had a lot of competition before Konoha was established.

Therefore, it is very normal for the Hyuga clan to have records of the Mangekyō Sharingan.

Of course, this is also because Hyuga Rinka has an extraordinary status in the Hyuga clan.

After all, in addition to being a member of the Hyuga clan, she was also destined to be the fiancée of Hyuga Hiashi since childhood.

As the fiancée of the young clan leader, Hyuga Rinka naturally has a high authority in the Hyuga clan.

On the other hand, the younger sister Hyuga Yuika.

The reason why she looked at her sister with a complicated look was because she didn't know anything about the Mangekyō Sharingan.

They were sisters from the same father and mother, but because they were born a few seconds later, they received completely different treatments in the clan.

"My lord, my sister was too reckless just now. You really should punish her." Hyuga Yuika suddenly interrupted and stepped forward to rub Naraku's shoulders.

"Oh? Then how do you say to punish your sister?" Feeling the rubbing of his shoulders, Naraku said to Hyuga Yuika's sudden move without changing his expression.

Hinata Yuika took a deep look at her sister who was looking at her in astonishment, and whispered: "Just punish her sister to hold my waist for the next week when I serve the master."

"Hold my waist? Oh, you mean that, it sounds good, so let's do it!"

I thought Hinata Yuika would propose some excessive punishment, but unexpectedly, it was just a light touch. Naraku couldn't help but smile playfully and agreed to the other party's proposal.

He had been with the twin sisters Hinata Rinka and Hinata Yuika for a while, so he naturally saw the relationship between the two sisters.

It's not the lack of wealth that is worrying, but the inequality.

Because of the completely different life of the younger sister Hinata Yuika, and the oppression of the main family after becoming a branch family, she has always been jealous of her elder sister Hinata Rinka.

If her life had not changed, Hyuga Yuika would undoubtedly end up like Hyuga Hizashi, numbly and powerlessly accepting her fate.

But now, her life has changed.

Although she is still controlled by the "bird in the cage", her sister is no longer the head of the family.

This gradually changed Hyuga Yuika's mentality, and she began to challenge her sister openly and secretly.

Some of them were in training, and some were in competition for Naraku's favor.

Naraku actually saw all of Hyuga Yuika's behavior.

He could actually understand this.

In terms of the other party's life experience and the oppression of the Hyuga clan towards the branch family, Hyuga Yuika's little jealousy is already a manifestation of sisterly love.

If it were someone else, they might have turned against each other long ago.

Therefore, as long as it is controlled within the red line, Naraku does not mind some of Hyuga Yuika's little jealousy.

After all, in terms of competition for favor, he is still the beneficiary.

The reserved Hinata Rinka blushed at the punishment proposed by Hinata Yuika, but she accepted the punishment obediently after Naraku agreed.

After teasing the two sisters, Naraku turned around and studied the newly evolved [Mangekyo Sharingan] in his hand again.

"After nurturing it for so long, it finally evolved again!"

Looking at the [Mangekyo Sharingan] in his hand, Naraku smiled.
