College student Lu Xilan received a strange letter. The sender was unknown to him, but he said that he had gone through countless reincarnations to save him, and emphasized some strange rules to him, hoping that he would abide by them. After Lu Xilan received the letter, a series of strange things began to happen.

What is all this about?
Can I really trust time?
Concept: reincarnation of time and space
