Naruto: Dawn of Che Uchiha

On the night of the Kyuubi, Konoha burned. Uchiha Che woke up in blood and fire and found that he had traveled through time and became an orphan of the Uchiha clan. Both parents are dead, the clan is under surveillance, and there is a night of genocide that is destined to come in the future. He had no bold words to save the world, and initially just wanted to survive. Fortunately, he has an almost systematic ability: he can analyze the ninjutsu when he sees it; he can reproduce it when he sees the seals. From Fire Release to Genjutsu, from Flying Thunder God to self-created Ninjutsu, from Sharingan to Rinnegan, he grew up in a low-key manner in the shadow of Konoha, and was forced by fate to rebel step by step. After Orochimaru destroyed Konoha, Uchiha Che left the village and founded the organization "Dawn". They are not Akatsuki, but they still collect tailed beasts; they want to stop the darkness, but they are also regarded as a new threat by the world. The last survivor of the Ichibi Guardian Family, ice escape ninjas from the Kirigakure Blood Mist Era, survivors from the Country of Whirlpool, wandering samurai from the Country of Thunder... A group of people who were abandoned by the ninja world, established their own base under the ice fields of the Snow Country. When Akatsuki began to take action, the fight for tailed beasts swept the ninja world; when the fourth ninja war broke out, and the shadows of Madara and Otsutsuki fell, Uchiha Che finally understood: The so-called dawn does not mean the absence of darkness. But there are people in the darkness who still have to ignite the first light with their own hands.
