In the wasteland doomsday, Shen Wuqiao becomes the only pure body not polluted, binding the turn-waste-into-treasure management system. She relies on scavenging to feed the system, upgrading from a small grocery store to a super store to establish a commercial district. Saving refugees abandoned by the high levels of the doomsday base, she upgrades and fights monsters all the way to find three older brothers and a childhood friend who treat her like their lives, making the doomsday wasteland regain vitality.
