I use the ninja world to help me cultivate immortality

According to the records about elixirs in the "Secret Book of Immortals".

Most of the elixirs found right now contain spiritual energy concentrations that are only about ten years old.

Of course, considering that Naraku is only at the second level of Qi training, the elixir of ten years has a good effect on him, enough to save him a lot of time in hard training.

Because there were guards and shadow clones placed around the wooden house, Naraku didn't have to worry about being disturbed while refining the elixir.

At that moment, he took a medicinal plant, sat cross-legged on a futon he bought, and then swallowed the elixir directly.

Ordinary people, even ninjas, are unable to refine elixirs.

Even if you eat it, the spiritual energy contained in the elixir will be discharged directly through the body, and the effects it can produce are no different from ordinary medicinal materials.

But Naraku, as a cultivator of immortality, is different.

As the elixir entered his belly, when he ran the nameless technique, the spiritual energy contained in the elixir was immediately refined by the true energy, allowing his cultivation level to be rapidly improved.

In just a moment, the elixir was completely refined.

Correspondingly, Naraku's cultivation level suddenly improved by the equivalent of nearly half a month of hard work.

Of course, this is without counting the assistance of the Qi Shadow Clone.

After personally feeling the effect of the elixir, Naraku couldn't wait to take another elixir.

The elixirs were refined one by one.

Naraku's cultivation level also increased.

Especially when refining several of the elixirs that were twenty or thirty years old, each one made him improve his cultivation by nearly one or two months.

When the last elixir was refined, the true energy around Naraku's body surged, as if an invisible force field had been formed.

It can be said that even if someone shoots Naraku with a kunai at this time, he will be blown away by the surging Qi.

After a while, the surging true energy returned to the body.

Naraku opened his eyes, and the divine light flowing in his eyes was enough to prove that his cultivation had been greatly improved.

"Yes, now the time until reaching the second level of Qi training will be shortened a lot." Feeling the current level of cultivation, Naraku nodded secretly, feeling very satisfied in his heart.

"There is a chance of buying elixirs in the medicine store, but you can only try your luck. In addition, I can't leave the village at the moment, so going to the medicine store to look for elixirs can only be regarded as a casual pick-up. The real stability is to rely on Practice on your own.”

A famous doctor once said that people must rely on themselves.

Naraku quite agrees with this statement.

So although he discovered that this world contained a magical medicine, he was not in a hurry to find it.

After all, what he is pursuing now is stable development.

Of course, the main reason for not being eager for the elixir lies in the existence of the True Qi Shadow Clone.

Although the cultivation efficiency brought by the Qi Shadow Clone is not as fast as the elixir, it is still quite significant.

Especially in terms of stability, he has enough patience.

"You want me to give you advice?"

"Yes, Mr. Naraku, since the last time I fought with you, I found that I still have many shortcomings, so I hope to get your guidance."

The entrance to the Ninja School office.

Originally, teachers and students would leave after school, but on this day, just when Naraku, no, it should be the shadow clone, was about to leave, he was blocked by someone.

This person is none other than Uchiha Shisui.

I saw Uchiha Shisui bowing towards the shadow clone respectfully.

"I refuse. You want to find someone to give you advice. I think there should be enough people in your clan. Okay, I have other things to do, so I'll leave first!"

Uchiha Shisui's attitude was very good, but unfortunately, it was completely useless against the shadow clone.

The shadow clone has no time to accompany the other person, let alone that he is just a shadow clone and cannot make decisions for the main body.

So after refusing without hesitation, the shadow clone bypassed the other party and strode away.

Uchiha Shisui turned around and looked at the shadow clone's leaving figure.

He didn't stop him, just scratched his head helplessly.

It failed.

It seems that I really can only find seniors from the clan to compete with me.

Uchiha Shisui came up with the idea of ​​​​looking for Naraku's guidance mainly because of his experience during the original assessment.

As a genius, he is very sharp.

From the initial fight, he vaguely sensed that Naraku's strength was much higher than what he showed as a first-year teacher.

So I came here to seek guidance this time. On the one hand, I really wanted to find a master to guide me. On the other hand, it was actually because I had made a lot of progress in these days and wanted to test Naraku's background.

After the shadow clone got rid of Uchiha Shisui, he skillfully found an uninhabited place to relieve himself.

at the same time.

In the wooden house at the training ground, Naraku, who was sitting on the futon, also received the memory from the shadow clone for the first time.

"Another troublesome guy!"

Naraku directly gave Uchiha Shisui the same evaluation as Kakashi.

Geniuses are often precocious.

He didn't think that Uchiha Shisui really came to him just for advice.

Shaking his head and throwing the troublesome guy out of his mind, Naraku adjusted his state again and prepared for the next breakthrough.

Yes, it is a breakthrough.

With the help of the elixir and after practicing hard for many days, Naraku finally succeeded in reaching the perfection of the second level of Qi training and was preparing to enter the third level of Qi training.

Stay focused.

It was only when night came that Naraku felt almost the same and began to break through.

Just like last time, under the operation of Wuming Kung Fu, Naraku continued to compress the true energy in Dantian until it was compressed to the limit.

Boom! ! !

What comes after the limit is an explosion.

The violent true qi swept through his limbs and bones, and the waves emitted made the whole wooden house shake.

"The resistance is much higher than last time!" Naraku was awed in his heart.

Facts have proved that the higher the realm, the more difficult it is to break through.

Compared with the last breakthrough, this time, Naraku clearly felt that the realm shackles were more solid.

Of course, this breakthrough did not fail because of this.

The shackles of the second level of Qi training are certainly stronger than those of the first level of Qi training, but under the impact of the pure and domineering true qi condensed by the nameless technique, it only lasted a little longer.

One wave after another broke out.

After a while, the invisible shackles were broken.

Buzz~!

The moment the invisible shackles were broken, Naraku's body shook slightly, and he ushered in a transformation again.

Between heaven and earth, spiritual energy was attracted and rushed into the wooden house frantically until it entered Naraku's body to provide nutrients for the transformation of the body.

This transformation lasted longer than the last one.

It took two or three hours for the transformation to end.

At the same time, the spiritual energy slowly returned to calm.

Opened his eyes.

Divine light flowed from his eyes.

Naraku, who was sitting cross-legged on the futon, seemed to sway for a moment, and the next second, he turned into a shadow and disappeared on the futon.
