Naruto: Kakashi is back with the system

The White Snake Sage looked at Orochimaru's actions in confusion, not understanding why he wanted to stop Kakashi. It seemed that he had no idea about Orochimaru's fickle temperament.

However, although the White Snake Sage is very old, he is not forgetful and he has certainly not forgotten what he promised to Kakashi.

"Are you ready?" The White Snake Sage looked at Kakashi, "If you are ready, let's start."

Kakashi didn't know what the White Snake Sage meant by preparation, but he still said that he was ready.

With a "swish", just as Kakashi nodded, a sound of breaking through the air was heard.

Kakashi had no time to dodge. He just felt a pain in his neck and then his consciousness became blurred.

Before completely losing consciousness, Kakashi only saw the White Snake Sage's neck slowly retracting, and then he realized what had just happened.

[No wonder people say that the White Snake Immortal has a weird personality and is hard to please. Orochimaru is right.]

He was talking to me in a friendly manner one second, and bit me the next.

Orochimaru caught Kakashi who was about to fall to the ground, but his eyes were fixed on the two bloody holes on Kakashi's neck.

He knew what this was. He had heard Tian Xinshen Ji mention it before. This was the necessary process for practicing the Longdidong Immortal Art.

However, perhaps because he was busy with the war, or perhaps because the risk was too great, he never accepted the offer from the White Snake Immortal.

Although no one has practiced the Sage Mode of Ryuchido so far, Kakashi's behavior is obviously not a normal reaction to practice.

The natural energy of the Ryuchi Cave was injected into Kakashi's body with the bite of the White Snake Sage.

Along with the natural energy, the spiritual power of the White Snake Immortal also entered.

Kakashi fainted because of the impact of this huge mental power.

The natural energy of Ryuchi Cave, which is the earth-attributed spiritual power, enters Kakashi's body and guides part of the spiritual power in his body to transform into earth-attributed spiritual power.

The tooth marks left by the White Snake Sage have slowly begun to heal, but Kakashi has shown no signs of waking up.

"It looks like he will sleep for a long time. If you have something to do, you can go back first."

Orochimaru did not reject the proposal of the White Snake Sage. Although he was one of the three great ninjas of Konoha, he was different from Jiraiya and Tsunade.

He is very busy. Although he is not required to go out on any mission, there are still many tasks that need him to preside over.

As for leaving Kakashi alone in Ryuchi Cave?

Judging from the prophecy made by the White Snake Sage, Kakashi should be safe in Ryuchi Cave, and he doesn't need to worry about Kakashi's safety.

Not until Orochimaru disappeared did the White Snake Sage sigh quietly, not knowing whether what he had done was right or wrong.

For some things you only have one chance, and if you fail, you fail.

Moreover, her contractor was too smart. He might have discovered her little trick and might become alienated from her...

Time flies, and there is no years in practice. More than a month goes by in the blink of an eye.

During the time when Kakashi was asleep, Orochimaru was not idle. It can even be said that his life was rich and colorful.

The first and most significant result was that the batch of clones he cultivated finally matured with the help of technology and chakra.

"Lord Orochimaru, shall we begin the next phase of the experiment now?"

"No, we need to wait a little longer."

Although these clones have matured, this only means that they have grown into a complete baby. They are still some distance away from reaching the experimental conditions for Wood Release cell research.

But who is Orochimaru? He is not only a genius in ninjutsu, but also a genius in scientific research.

"I have prepared a special nutrient solution, and it won't be long before they can start the experiment."

Although the Wood Release Cell experiment could not be carried out, the Reincarnation Experiment that he had been planning for a long time could be tried.

Although he has succeeded countless times in his dreams, he has never tried it in reality.

Orochimaru, who has been poisoned by dreams for a long time, is now full of awe for life and cherishes his own life more.

He did not experiment on himself, but instead found a dying person.

That man was also a ninja, but retired due to serious injuries.

Now that he is old and frail, all the hidden injuries he suffered have now erupted, and the Konoha Hospital has diagnosed that he has less than a month to live.

Now that he has the opportunity to live his life again, there is naturally no reason for him to refuse.

Although there is a risk of failure, he was once a ninja after all, so he still has some adventurous spirit.

If you win, you can live one more life. If you lose, you will just go to the Pure Land a month earlier.

"Master Danzo, the experiment over there has been suspended again."

The experiment of reincarnation is a secret experiment of Orochimaru which is still kept confidential. It will naturally not be carried out in public.

So, Orochimaru left with a mature cloned embryo.

"Hey--" Danzo sighed, "Never mind him, how is the experiment going on here?"

The researcher in the white coat suddenly didn't dare to speak. It was obvious that the experiment had failed again.

Although this person didn't say anything, his posture said it all.

"Ah——" Danzo let out another long sigh.

He always wondered if he had committed some kind of bad luck. Ever since he missed the chance to become Hokage, his luck seemed to have been bad.

"Are there enough experimental subjects?"

“……”It was obvious that none of the subjects who participated in the experiment survived.

"Master Danzo, perhaps we can choose younger test subjects, so that the success rate may be higher."

Although this researcher was not convinced that Orochimaru was in charge of such an important research, he still recognized Orochimaru's research ability and believed in his judgment.

In his opinion, a ninja should do what a ninja should do, why should he cross borders to do research?

Especially since Orochimaru's research is not bad, how should those who are professional researchers deal with this?

"Didn't we ask the intelligence team to investigate the basic information of the students in the Ninja School before? Let them pick a few suitable ones from among them."

In Danzo's view, other people's lives are not lives, only his own life is the most precious.

It was an honor for those little kids to be able to sacrifice for him.

The person they sent out to search for information about the ninja school was not just the teacher in Kakashi's class, but he was the only one who chose to become a teacher.

"Remember to be discreet and don't let anyone see you."

But things often develop in the direction that people least expect.

The more Danzo didn't want to be discovered, the more clearly he was seen.
