The protagonist, Lin Ye, was a Blue Star doomsday survivor in his previous life. He died in the seventh year when the strangeness came and was devoured by the high-level strange "Nightmare Lord". He was reborn seven days before the strangeness came, when he was still an ordinary college student. He has a calm and decisive personality. After experiencing the baptism of doomsday, he has become extremely rational and vigilant, but deep down he still retains his trust and sense of responsibility for his companions. After his rebirth, he mastered strange information and key nodes for the next seven years, but found that he had changed the direction of some events like a butterfly effect. The growth arc shifts from "surviving alone" to "cultivating forces and fighting against world-class disasters", and finally transforms from a survivor into a guardian of human civilization.
