They have been practicing for generations. They are all vying for the position of the strongest ninjutsu family (actually, I don’t know why these two families are fighting. I just vaguely remember an episode mentioning that the two families are descendants of the Six Paths Sage, and each inherited a power of the Six Paths. They There are differences in worldviews. One believes that the world must be conquered with force, while the other believes that the world must be ruled with love.) In the end, the leader of the war faction of the Uchiha clan, "Uchiha Madara", was defeated by the leader of the Senju clan, the First Hokage. Hashirama" was defeated and left the Uchiha clan alone. The Uchiha clan was also tired of the war, and other members agreed to "Hashirama"'s recruitment and stayed in Konoha. After "Hashirama" died, his younger brother became the Second Hokage, but his style was not like his older brother. He was very afraid of the Uchiha clan, so he created the "ANBU" to monitor every move of the Uchiha clan. Later, he handed over the Anbu to his apprentice "Duanzang" and continued to monitor Uchiha, causing the Uchiha clan to resent the Leaf Village.
The third plot (in chronological order, it is an interlude, with several important characters appearing). The third generation Hokage trained three major disciples: Steel Hand, Jiraiya, and Orochimaru. Known as the "Three Ninjas of Konoha", Orochimaru fled Konoha Village after being discovered in order to study forbidden ninja techniques. Jiraiya accepted his disciple: Namikaze Minato (the fourth generation Hokage), and believed that he was the savior of the ninja world (the ninja world was divided into five major countries, and wars continued. Jiraiya always believed that a prophesied son would appear to end the ninja world. During the war of the world, Minato was the first savior he considered); Namikaze Minato accepted three apprentices: Uchiha Obito, Lin, and Kakashi, and both Kakashi and Obito liked Lin very much. During the Third Ninja War, Minato Namikaze and his three disciples were on a mission. In order to save Lin, Kakashi and Obito were injured in one eye, and half of Obito's body was pressed down by a boulder. Before he died, Tu made two requests: 1. Ask Lin to transplant one of his eyes to Kakashi. 2. Ask Kakashi to take good care of Lin. But Obito did not die. He was left by Uchiha Madara. The old Uchiha Madara was no longer able to move.

Madara agreed. But as soon as he returned to the present world, Obito saw Lin being killed by Kakashi. Obito was filled with grief and anger. He couldn't bear to kill Kakashi, but he couldn't forgive Kakashi, and he also lost hope in this world. Agreeing to Madara's request, Madara's plan has two requirements: 1. Find the user of the Samsara Eye ability and resurrect him with the art of reincarnation; 2. Resurrect the Ten-Tails and implement the "Eye of the Moon Plan".
