I'm doing scientific research in the Ninja World

"It seems that I don't have a talent for space!"

Looking at the recorded Flying Thunder God Technique in front of him, Orochimaru couldn't help but sigh.

In the original work, it shouldn't be difficult for Orochimaru to get this ninjutsu. Not to mention the deal with Danzo, he himself has been to the forbidden land of sealing techniques, it is impossible that he can't get this ninjutsu.

This ninjutsu that is very practical for running away and killing enemies will not be unattractive to Orochimaru, but he didn't learn it later.

I think he probably didn't learn it. Don't look at Orochimaru now has the space-time ninjutsu of Tenki Tokusatsu, which is a system reward, equivalent to initiation, and he doesn't have to learn it from scratch.

"Except for Minato, no one else in the whole Konoha has learned it. It seems that this ninjutsu is not for me!"

After becoming Hokage, Minato also taught this space ninjutsu to his four guards, but no one could learn it. Two of them can cooperate to use the teleportation array.

Thinking of this, Orochimaru put away the scroll in dismay. It was not bad to have Xiang Zhuan, but he could not use Flying Thunder God Thunder from a long distance like Minato.

Close contact can also transfer the Tailed Beast Ball, and there is no need to transfer it with his special physique, just absorb and release it directly.

After putting away the Flying Thunder God Technique, Orochimaru took out another ninjutsu scroll, which was the Impure World Reincarnation Technique.

A month later, in a cave ten kilometers away from Konoha.

Orochimaru looked at the middle-aged ninja with countless cracks on his skin in front of him. He saw that this ninja was wearing blue armor, a Konoha forehead protector, and two narrow red spots on both sides of his cheeks. It was the second generation Hokage, Senju Tobirama.

Orochimaru had extracted the body tissue of the second generation Hokage a long time ago, and caught a heinous bandit in a small village near Konoha as a container to reincarnate.

After putting a kunai with a talisman on it into the back of his head, the Second Hokage gradually regained consciousness.

"Second Hokage, long time no see!"

Orochimaru kept making hand seals while looking at the Second Hokage who had regained consciousness.

"Hmm? Didn't I wake up? Who are you? Where is this?"

Senju Tobirama saw Orochimaru the first time he woke up, and looked around.

He found that the place was densely packed with information books, as well as some research equipment.

"Master Tobirama, you are indeed dead. You are now my reincarnation through the Impure World Reincarnation."

After a pause, Orochimaru continued:

"This is one of my research institutes. As for who I am, I am your disciple, Orochimaru. I met you several times when I was a child!"

When he heard Orochimaru say that he was reincarnated through the Impure World Reincarnation, Tobirama looked down at his hands and realized his current state.

And when he heard Orochimaru say that he was his disciple, his originally vigilant heart relaxed a little.

"A disciple of the monkey? What's the matter with you summoning me? You should know that it is very disrespectful to disturb the dead at will!"

Realizing that he could not be free, Tobirama simply crossed his arms to see what Orochimaru wanted to do.

Since his physique became that of the Uzumaki clan, Orochimaru's chakra is no longer the same, about five times more than before.

No wonder Mito could extract the chakra of the Nine-Tails before he completely tamed it. This body is really amazing.

With a large amount of chakra as a support, Orochimaru is not afraid that Tobirama can get rid of his control.

"I summoned Tobirama out of helplessness. Recently, I have been studying a ninjutsu to deal with Uchiha's illusion, but I have encountered some difficulties and need your guidance."

Orochimaru did not hide his purpose and told his purpose.

It is indeed as he said that he summoned him out for academic discussion.

If we talk about who is the best in the development and research of ninjutsu in the ninja world, no one dares to say that Senju Tobirama is the best.

Orochimaru also learned the Impure World Reincarnation, and the first thing he thought of was not to summon a psychic to fight, but to summon a psychic to teach him.

If Tobirama had known that he would not need to summon a psychic with such a learning spirit, he would have wanted to open the coffin lid to discuss academics with him!

And Tobirama was a little surprised when he heard Orochimaru say that he summoned a psychic just to study ninjutsu with him.

Or to deal with the evil Uchiha, he immediately became interested and simply sat down cross-legged.

"Just for this?"

Tobirama still stared at Orochimaru's eyes with a little disbelief, and Orochimaru also looked at him without dodging or evading, without any guilt.

"Master, I want to improve so much!"

This word of master made Tobirama's eyes a little dazed, as if he had returned to the time when he taught Danzo, Sarutobi Hiruzen, Uchiha Kagami and others.

"Go ahead, what do you want to ask?"

Seeing that Tobirama had initially accepted hisWith his own reasons, Orochimaru also loosened his control and took a stack of information from the side.

They were all about sealing techniques and spiritual power ninjutsu, such as the Diamond Seal, the Eight Diagrams Seal, the Four Symbols Seal, the Spiritualization Technique, the Darkness Technique, etc.

There were also many comments on Orochimaru's opinions. It was Orochimaru who was currently studying new ninjutsu to deal with Uchiha's illusions, the sealing technique to seal spiritual power, the Eight Gates Golden Lock.

"You have learned a lot!"

Tobirama took it up and read it carefully with interest. At this moment, he completely believed that Orochimaru had gone to great lengths to summon him to develop new ninjutsu.

"I only know a little bit."

For the textbook-level second-generation Hokage, the ninjutsu he knew was countless, and the forbidden techniques he developed were also countless.

Even if there were more information and more ninjutsu, how could it compare to the personal teaching of the second-generation Hokage?

In the original work, Orochimaru may not have been able to fully understand the Impure World Reincarnation, or he may have limited ability and did not dare to do so.

You know, if you don't do it well, you will be killed by the summoned Second Hokage, not to mention that Orochimaru had already defected at that time, and he didn't dare to learn the ninjutsu taught by the Second Hokage.

If he teaches you the wrong method, he won't have to practice it himself and he will die.

In the following time, Orochimaru smoothly discussed the development of the Eight Gates Golden Lock with Tobirama.

From the conversation, he also noticed Orochimaru's super high understanding, otherwise he would not have thought of such a unique way to develop new techniques.

Orochimaru was a little wary of him at first, but as time went on and the discussion deepened, Orochimaru unconsciously let go of his control until he completely let go.

It's not that Orochimaru is careless. Even if Tobirama suddenly attacked, he couldn't kill him, and it would be even more impossible if he wanted to leave.

Orochimaru had already set up a barrier outside, and he couldn't leave for a while. Even with Flying Thunder God, he couldn't get out without a mark.

Besides, Orochimaru was not a pushover. As long as he had a little reaction time, he could control Tobirama again. That was why Orochimaru was not worried.

As for the hand seal control at the beginning, it was also because he was worried that he would mess up after waking up and not understand the situation.
