Chapter 86: Tobirama: I’ll hang Danzo and whip him!
Some people understood.
It turns out he used Impure World Reincarnation!
This is indeed a good method, and Jiraiya and the others had also heard about the forbidden technique developed by the Second Hokage. Unfortunately, it was sealed by the Third Hokage long ago. Even their disciples were out of reach.
At the same time, Impure World Reincarnation is one of the most difficult forbidden techniques. Except for Orochimaru, even Jiraiya was unsure about learning it.
"Impure World Reincarnation requires sacrifices and personal information materials from the target..."
"I have this!"
Tsunade responded very urgently.
It was just a little hair and blood. As a medical ninja, she naturally saved some.
"As for the living sacrifice?"
"Leave this to me." Minato volunteered.
There were many criminal fugitives and spies from enemy villages imprisoned in the Uchiha security force prison, and they were useful as sacrifices. After all, there was no extreme notion of human rights in the ninja world.
