On January 1, 2040, pink particles fell from the sky. After the tragic death of the doomsday, 17-year-old Lin Yunxi returned to the three years before the disaster. She remembers that the hospital was full, the list was cleared, and she also remembers the order in which her loved ones fell; but the wrist device monitors all sounds, and the truth about her rebirth cannot be told. In order to change the fate of her family, she could only rely on notes and passwords to sell her house, stock up on medicine, hide files and train people, and bring her relatives into the mountains step by step. When the night of ground zero falls, the survivors begin to mutate, and the "peace observers" approach again, following the registration list. Lin Yunxi finally understood that this was not a natural disaster, but a precise screening. If she wants to survive, she must first remove her entire family from the list, and then find the person who actually holds the knife.
