I use the ninja world to help me cultivate immortality

"The village needs light, but it needs darkness even more. From today on, you are the darkness under the light, and the roots under the shadow of the big tree of the village."

"Yes!" ×100.

"Three years, you have been members of the training class of [Root] for three years, but I want to tell you that the real training has just begun.

In addition to doubling the amount of training, you must take this medicine every day, which will bring you stronger strength.

In addition, until you are promoted to a reserve member, the last elimination system will be implemented every month, and those who are eliminated will not be qualified to become [Root] members."

"Yes!" ×100.

"Very good, after rigorous training, you have all become qualified members of the training class. Next, until you reach adulthood, you will be eligible to participate in the annual assessment, and those who pass the assessment can be promoted to a reserve member."

"Yes!" ×40.

"No. 1, congratulations on your successful promotion to a reserve member. You are now eligible to have a real code name. What code name do you plan to give yourself?"

". Ghost!"

"Ghost? I remember your name is Naraku, No. 1, right? The code name Ghost is quite suitable for your name."

"Thank you!"

"Okay, since you already have a code name, let's start the final ceremony!"

"What ceremony?"

"'The Seal of the Tongue'!"

"Ah!!!"

The shrill screams echoed in the dark secret room.

Konoha!

Ninja School, first-year teacher's office.

"Have you heard that Uchiha Shisui from Class A has applied for early graduation."

"Ah! Is this true? He has only been in the first grade for three months."

"Ordinary students definitely can't do it, but isn't this Uchiha Shisui? You have seen his usual performance. Not to mention senior students, even some Genin may not be as good as him."

"That's right. I remember that Uchiha Shisui is only five years old now. Isn't this the same as Hatake Kakashi back then? If he passes the test, wouldn't he break Hatake Kakashi's record as the youngest Genin?"

"That's true. Hatake Kakashi graduated early after half a year of enrollment. If Uchiha Shisui succeeds, he will really break the record."

"Haha, after all, they are the wealthy Uchiha. Although the people of this family are mostly arrogant, their talents are indeed not comparable to those of us common people."

In the office, a group of teachers were discussing enthusiastically.

Some sighed, and some were sarcastic.

At this time, a teacher wearing glasses couldn't help but talk to another teacher at the opposite table.

"Naraku, do you think Uchiha Shisui can pass the test successfully?"

The teacher sitting opposite, called Naraku, looked much younger than other teachers in the office, and looked only about 17 or 18 years old.

In addition, his appearance was also very outstanding, and he could be called handsome.

Naraku was originally preparing for class with his head down, and did not participate in other people's discussions, but when his colleague at the opposite table specifically asked, he still looked up politely at the other party.

"I think there is still a lot of hope, after all, Uchiha Shisui's excellence is obvious to all." Naraku replied seriously.

"Yes, it seems that Kakashi's original record is really going to be broken." The glasses teacher thought about it and couldn't help but sigh.

Compared with Naraku, who has only been employed in the Ninja School for half a year, the glasses teacher has been working in the school for more than ten years.

Naturally, he also taught Kakashi three years ago.

Compared with Kakashi at the beginning, the glasses teacher had to admit that Uchiha Shisui now seemed to be more outstanding.

Back to Naraku.

After briefly chatting with the glasses teacher about Uchiha Shisui, he quickly lowered his head to continue preparing lessons.

Well. At least on the surface.

"Is Uchiha Shisui still having such an experience? I didn't expect it, but according to the atmosphere of the Uchiha clan striving for the first place in everything, I'm afraid that Uchiha Shisui himself doesn't want to do this, and his clan will also ask him to compete."

Turning the pen flexibly, Naraku thought about it for a while and didn't think about it anymore.

After all, in his current situation, he doesn't have the extra energy to care about others.

Pretending to be busy, Naraku patiently waited for the end of get off work as always.

Dinglingling...

Time unknowingly came to the evening.

Suddenly, with the ringing of the school bell, the whole ninja school suddenly became lively.

Students of all grades ran out of the school happily.

The teachers were similar.

Everyone unconsciously unloaded their burdens, and left in twos and threes with a relaxed look.

Naraku did the same, but he did not leave the school, but found a corner where no one was.

"Release!"

After making sure that there was no one around, Naraku formed a seal with his hands in front of him, and in an instant, with a bang, he disappeared.

This turned out to be just a shadow clone.

In an apartment in Konoha's residential area.

The light of the setting sun shone on the bed through the window.

On the bed was a black-haired young man sitting cross-legged with his five hearts facing the sky.

This person was Naraku.

Suddenly, as the shadow clone of the ninja school was released, Naraku, who was sitting cross-legged on the bed with his eyes closed, slowly opened his eyes.

"It's time to go home, time flies so fast." Naraku sighed in his heart and then closed his eyes again.

No way, now is the critical period of cultivation.

After persisting for half a year, after the perfection of "calming the mind", "concentrating the mind" is also about to be perfected.

Once "calming the mind" and "concentrating the mind" are perfected, he can sense and breathe the spiritual energy of heaven and earth, and then become a cultivator.

That's right.

For Naraku, using the shadow clone to take charge of the affairs of the ninja school instead of himself is not just for laziness, but to create more time for cultivation.

The most important thing is that what he practices is not the ninja method circulated in this world, but the method of cultivating immortals.

Naraku is a cultivator, and he is also a time traveler.

However, unlike most time travelers who take over bodies, he is reincarnated and reborn in the present world.

Almost half a year ago, an unexpected experience awakened his memories of his previous life.

In the memory of his previous life, the ninja world he is in now is just from an animation.

Of course, this is not the most important thing. The important thing is that with the awakening of the memory of his previous life, there is also a bronze tower in his mind.

When he digested the memories of his past life and resonated with the bronze tower in his mind, he realized that the bronze tower was the golden finger of him, a time traveler.
