In the anime Naruto, the reincarnation eye is the exclusive ability of the six immortals, after the death of the six immortals, the reincarnation eye also disappeared in the ninja world, but in the era of Uchiha Ban, there was a change, Uchiha Ban in the Valley of the End of the Battle of the Thousand Hands Pillar, but Ban did not die in battle, but got a piece of flesh from the Senju Pillar, and transplanted into his own body.
The Six Immortals had two sons, Ōtsumu Indra and Ōtsuki Asura, who had said that they would be reborn in their lifetimes, and the reincarnations of this generation were Uchiha Ban and Senju Pillar, but Uchiha Ban transplanted the cells between the Senju Pillar into his own body, and after combining the power of Indra and Asura, he finally led to the power of the Six Immortals and opened the reincarnation eye.
However, after awakening the reincarnation eye, Uchiha Ban was already an old body, at this time Uchiha Ban was already full of white hair, without the support of the Outer Path Golem, Uchiha Ban's life could not be guaranteed, and at this time Uchiha Spot found a way to return himself to the peak, that is, to transplant the Reincarnation Eye to others, and after catching the nine tailed beasts, then resurrect it.
At this time, the person that Uchiha Spot found was Nagato of Yukuma Village, Uchiha Spot after transplanting the reincarnation eye to Nagato, he found a pair of writing wheel eyes transplanted to his body, and at this time, Uchiha Spot met Uchiha Belt Soil, under the arrangement of Uchiha Spot, Uchiha Belt Soil successfully blackened, just like this, Ban's spokesperson in this world appeared.
But Uchiha Ban is obviously a member of the Uchiha clan, so why transplant his reincarnation eye to Nagato, a foreigner? Wouldn't it be better if he transplanted the reincarnation eye to his own Uchiha clan? Moreover, Uchiha had not yet exterminated at that time, and there were many choices for Uchiha Ban, so why did Uchiha Ban take a fancy to the Nagato of this Yuyin Village?
First of all, Nagato has a red hair, red hair in the anime is the characteristic of the Whirlpool family, so Nagato's body is flowing with the blood of the Whirlpool family, the Whirlpool family and the Uchiha family and the Senju clan, all are descendants of the Six Immortals, so Nagato itself can also support the power of the reincarnation eye, not only that, Nagato in addition to the Whirlpool family has another bloodline.
In Nagato's body, in addition to the bloodline of the Vortex clan, there is also the bloodline of the Senju clan, which is also the reason why Uchiha Spot has taken a fancy to Nagato, the power of the Vortex Clan and the Senju Clan can well neutralize the side effects brought by the reincarnation eye, so Uchiha Ban chose Nagato, but also looked at Nagato's physique, and Nagato is indeed a very good user of the reincarnation eye.
As for why Uchiha Ban did not choose Uchiha's clan, in fact, the reason can be seen from the Uchiha belt soil, after defeating Xiaonan, the belt soil only transplanted one reincarnation eye, in fact, it is not that he does not want to transplant another reincarnation eye, but the power of the two reincarnation eyes is too overbearing, just one reincarnation eye almost makes the belt soil lose itself, let alone two?
And Uchiha Ban chose Nagato, which is also a combination of the power of the Senju clan, the Vortex clan and the Uchiha clan to control the reincarnation eye, and then find the belt to supervise Nagato, so that it can be regarded as prepared.
In your opinion, why didn't Uchiha Ban give the reincarnation eye to others?
