Seven years after the nuclear explosion, Lu Xiao hunted mutant creatures alone in the ash wasteland until he retrieved Jiang Zhuo, who was supposed to have died three years ago in a collapsed biological laboratory - she had tubes inserted all over her body, and her heartbeat was weak but real. No one believed she could come back to life, but the first thing she said when she opened her eyes was: "You haven't bought me that red scarf yet." Lu Xiao silently put the last half of the energy block into her hand. He knew that the living people in this wasteland need reasons more than the dead. And she is his only coordinate to restart the world.
