In the anime Naruto, the reincarnation eye can be said to be the strongest of all the pupils, and in the anime, the six immortals and Uchiha ban have awakened the special ability of the reincarnation eye, especially Uchiha ban, after he awakened the reincarnation eye, he is already an elderly man, in order to launch the infinite moon reading, he transplanted his reincarnation eye to Nagato, who was still a child.
During the Second Ninja War, Nagato, Yahiko, and Konan met Uzumaki and became ninjas under Uzumaki's teachings, and after Uzumaki left Yuyo Village, the three of them established the Xiao Organization together, and when the Akira Organization was first established, the leader was not Nagato and Konan, but the two of them' good friends Yahiko, and after Yahiko's death, Nagato took over the Xiao Organization.
Due to Yahiko's death, Nagato's entire body began to rampage, and the last Nagato could be said to have been affected by the power of the Reincarnation Eye, and during the battle with Yamaji Hanzo, Nagato's feet also lost the ability to move, and after the battle, Uchiha took the soil to find Nagato again, explained the Moon Eye plan, and also taught Nagato the tricks of the Reincarnation Eye.
Since Nagato lost the power of action, Nagato could only choose to control the six Penns to help him act, and the abilities of the six Penns were also completely different, each Payne had one of Nagato's abilities, but there was one ability except, that is, the power of the outer path, Nagato could resurrect the dead through the power of the outer path, which was also the resurrection technique prepared by Uchiha Ban for himself.
Some people will say that Nagato's Outer Path Reincarnation Technique has requirements for the deceased, and it must be possible to die within a period of time, but this is not the case, since Uchiha Ban has resurrected Nagato himself, it means that Uchiha Ban must have been prepared earlier, but there is also a very big problem, since Nagato has learned the resurrection technique, then why didn't he directly resurrect Yahiko?
First of all, Yahiko's body is still in Nagato's hands, so Nagato still has a chance to resurrect Yahiko, although Yahiko's body has been inserted by Nagato with a lot of black rods, but for a ninja, these are nothing. But if that's the case, why didn't Nagato choose to resurrect Yahiko? In fact, one of the most crucial factors is to take the perfect infinite monthly reading in the mouth of the soil.
Nagato is actually a person who has no opinion, so Yahiko's dream has become Nagato's dream, after Yahiko's death, Nagato can completely resurrect Yahiko, but Nagato did not do this, because Nagato Way, even if he resurrects Yahiko himself, this ninja world will not change, so it is better to directly launch the Infinite Moon Reading and let Yahiko see the perfect world.
In order to achieve this goal, Nagato chose to help Uchiha take the earth to launch the Infinite Moon Reading and capture the tailed beast, and before that, Nagato must make the whole world feel the pain, only after feeling the pain, the people in this world can cherish the rare peace, in Nagato's heart, if you want peace, you must first feel the pain.
Nagato chose Kiba Village, also because there are indeed a lot of grudges between Kiba Village and Nagato, in the Second Ninja War, the ninjas of Kiba Village accidentally killed Nagato's parents, and in the negotiations with Yamaji fish Hanzo, it was still the ninjas of Kiba Village who came out to interfere, so Nagato would choose the ninjas of Kiba village, and there was a reason for it.
In your opinion, why didn't Nagato directly resurrect Yahiko?
