(PS: There are many bugs in Naruto's timeline before Naruto was born, and it's very messy. So here is the timeline written according to my own ideas)
Yu Dao traveled to the world of Naruto and accidentally met the Yahiko trio.
In the confrontation with Sanshouyu Hanzo, Yu Dao accidentally awakened the swastika system.
Ever since, a brand new Akatsuki was born.
Yahiko: "How can we achieve peace in the ninja world?"
Yu Dao: "It's very simple! Just achieve unification!"
Uchiha Madara: "Oh? You said you want to compete with Fire Escape? You are the most talented ninja I have ever seen! In terms of courage, I, Madara, am willing to call you the strongest!"
Yu Dao: "Really? Swastika: Can Huo Tai Sword!"
Ohnoki: "Akatsuki lacks the annihilating power similar to tailed beasts. We only need to send out a few elite ninjas and jinchuriki to destroy Akatsuki!"
Yu said: "??? Swastika · Bird Bee Thunder Whip!"
Otsutsuki: "He's just an animal with a knife, there's nothing to be afraid of!"
Yu said, "!!! Swastika interpretation, real fighting, white pen and one character!"
Obito: "Next, I'm going to tell a story about Kamui finally smiling!"
I can't be the only one hurt!
