As a very strong blood inheritance limit in the early stage, the writing wheel eye is portrayed with a lot of pictures. At first, Kakashi was simply handsome when he used the Sharingan Copy and then didn't slash the ninjutsu, but it was clear that he started it with his back hand, but he was able to rub it out at the same time.
Because of Kakashi's skillful use of the Sharingan, everyone is full of expectations for the Sharingan, especially watching Sasuke open Magatama more and more step by step.
And the exact form of the writing wheel eye turned out to be the reincarnation eye, because it is extremely difficult to open, and only the six immortals, Madara, Nagato, Obito and Sasuke have reincarnation eyes in the entire plot.
So will the reincarnation eye overwrite the original ability after it is opened?
(1) Spots
During the Battle of the Valley of the End, Madara bites off a piece of flesh from the pillars and extracts the cells from the meat.
After years of painstaking research, he finally opened the special reincarnation eye in his old age, because the special ability in the reincarnation eye was born, so that Madara had a chance to resurrect, so he instructed Obito to help him work behind the scenes.
Madara's kaleidoscope doesn't use any special ninjutsu throughout the plot, but he always uses Susa more in battle, especially the complete body Susa.
But he also opened Susa when he didn't have eyes, and he was still able to open Susa when he was reincarnated.
It can be seen that his reincarnation eye does not cover the abilities possessed in the writing wheel eye, and the reincarnation eye also brings more powerful ninjutsu - Wheel Tomb, Border Prison, Heavenly Hindrance Earthquake Star, etc.
(2) Soil
Obito itself does not have a reincarnation eye, his reincarnation eye was obtained from the dead Nagato, and Nagato's reincarnation eye is from Madara.
Because he gave Kakashi a chakra when he was dying as a teenager, Obito never had a chance to open his own Susa, and it wasn't until he was dying that he gave Kakashi his Kamui, and his Susa appeared on Kakashi.
One eye of Obito is a kaleidoscope of Kamui and the other eye is the eye of reincarnation, he is more flexible in battle, and the two eyes are used alternately.
For him, there is no question of coverage.
(3) Sasuke
Sasuke's reincarnation eyes are very special, not like Madara and the Six Paths Immortals, but Magatama reincarnation eyes.
In the process of fighting Madara, neither Naruto nor Sasuke was Madara's opponent, Sasuke was directly stabbed in seconds, and Yakushidou saved Sasuke with interpillar cells, so he naturally became the second person who had Uchiha blood and obtained interpillar cells.
This is not enough for Sasuke to immediately open the eye of reincarnation, after all, even Madara only opened it in old age.
It was the power of the six realms given to him by the six immortals that he quickly opened the eye of reincarnation. The strange thing is that he doesn't have two eyes that become reincarnation eyes, maybe like Madara, he can only open another reincarnation eye when he is old.
Like Obito, he also maintains the form of one writing wheel eye and one reincarnation eye, and in this case, Sasuke's writing wheel eye ability is completely retained.
Amaterasu, Kagu Earth, Amaterasu, etc. are all fully able to be used normally in battle, and they have also obtained a special space-time ninjutsu in the eyes of reincarnation - Tianshou power.
(4) Write last
After Madara, Obito, and Sasuke obtained the Samsara Eye, their ability to write the Samsara Eye still exists, and the enhancement of the Samsara Eye may be superimposed on each other like Naruto's various modes, rather than a form of coverage.
