Start with the Immortal Master Slaying the Demon

A slight mistake can lead to a mistake of a thousand miles. Throughout history, every seemingly small deviation will lead to a wrong new world. For example... The demon is in power and brings trouble to Chao Gang. For example... Mythical creatures appear in the world, and there is really a dragon under the Dragon Lock Well. For example... The supernatural no longer exists in picture books, but is integrated into reality. In the countless chaotic worlds, we are not there to correct mistakes, but to witness and collect them.
