In the anime Naruto, the origin of the ninja begins with the arrival of Ōtsuki Kiyoya to Earth, after Ōtsuki Kiyome came to Earth, Akiya absorbed the Chakra fruit, and as the son of Akiya, the Rokudo Immortals also possessed a part of the power of Akira and taught the use of Chakra to others, and the Rokudo Immortals became the ancestors of all ninjas in the future.
Before sealing hui ye, the six immortals had come to Myoki Mountain to learn the immortal mode, and at this time, the hui ye had already swallowed the complete body of the divine tree, so the red reincarnation writing wheel eye also appeared on the forehead of the hui ye, but after the six immortals awakened the reincarnation eye, the six immortals themselves also changed, in addition to the reincarnation eye, the red mark also appeared on the forehead of the six immortals.
In the Fourth Ninja War, Uchiha Ban became the pillar force of the Ten Tails, awakening the power of the Six Immortals, and when Uchiha Ban launched the Infinite Moon Reading, we saw that the red reincarnation writing wheel eye also appeared on Uchiha Ban's forehead, so the question is, why do ban and Hui Ye both have reincarnation writing wheel eyes, but the six immortals who are the ancestors of ninjas do not?
But why didn't the reincarnation writing wheel eye appear on the forehead of the Six Immortals? The first thing we know is that Hui Ye ate the Chakra Fruit before launching the Infinite Moon Reading, and Uchiha Ban also absorbed the power of the Divine Tree before launching the Infinite Moon Reading, the two are actually the same kind of energy, after getting the power of the Divine Tree, Uchiha Ban and Hui Ye awakened the reincarnation writing wheel eye.
Uchiha Ban first absorbed the power of the nine tailed beasts during the Ninja War, but at this time, Uchiha Ban did not reincarnate to write the wheel eye, and after Naruto and Sasuke got the power of the six paths, Uchiha Ban heard the power from the Divine Tree, at this time Uchiha Ban absorbed the Divine Tree, and it was after absorbing the Divine Tree that Uchiha Ban launched the Infinite Moon Reading.
On the other hand, after sealing hui ye, he only became the human pillar force of the nine tailed beasts, and did not absorb the power of the divine tree, because some of the power of the divine tree had been sealed with the hui ye in the moon IQ, and the remaining power was also divided into nine parts by the six immortals, that is, the later nine tailed beasts, so the six immortals did not have reincarnation to write the wheel eye is also related to this.
That is to say, the power possessed by the Six Immortals was incomplete, in addition to the power of the nine tailed beasts, the Six Immortals also lacked the power of the Outer Path Golem, but on the other hand, if the Six Immortals absorbed the Outer Path Golem, then he himself became the medium of resurrecting the Night, so that it seemed that there was no need for The Black Jedi to go to Indra.
So if the mark on the forehead of the six immortals is not the reincarnation writing wheel eye, then what does this part of the energy represent? In fact, there are still some hints in the anime, we all know that Naruto comes from the Vortex clan, and the Vortex clan is also a descendant of the Rokudo Immortals, and the logo of the Rokudo Immortals and the mark on the forehead of the Rokudo Immortals also coincide.
Therefore, the power represented by the wheel eye of reincarnation writing is the power of the divine tree, only after absorbing the divine tree can you have such a special eye, and only after absorbing the power of the divine tree can you launch the infinite moon reading on your own, if there is no support from the special power of the divine tree, it is impossible to launch the infinite moon reading.
In your opinion, why don't the Six Immortals have reincarnation to write the wheel eye?
