Yan Li is reborn seven days before the apocalypse arrives. Her grandfather leaves behind a pair of bracelets, and her cousin Yang Qingyi feigns picking the ugly wooden bracelet—the treasure that awakened healing powers in the previous life, where Yan Li was used as a mobile blood bag because of her ability and ultimately died a tragic death. In this life, Yan Li accepts the space jade bracelet, immediately sells her house to stockpile supplies, cuts ties with relatives, and hides in a safe house. As extreme cold plunges and zombies erupt, she tightly closes her door and refuses to be a saint, relying on a full warehouse of supplies and a cold blade to survive alone in the apocalypse.
