Don't Look at It, Night

The bloody setting sun hangs in the sky, only one-seventh of the sky is illuminated, dead bones are everywhere, and countless zombies are wandering in the ruins of doomsday. This is Mo Xin's memory of the end of the world before he was reborn. After rebirth, he originally wanted to reach the top of the world with the memories of his previous life, but he realized that something was not right now. What kind of soulless people, what kind of soulless people, what kind of second- and third-level world lines, Is this the end of the world or a jump back and forth in the tree diagram?
