The story takes place on two planets in the interstellar world - Tianshu Planet (where the Su family, a prominent ancient family, mainly engaged in silk business) and Huangxing (a doomsday wasteland, depleted of resources, full of radiation, refugees and dangerous creatures). Tianshu Star follows the ancient family hierarchy, and the Su family is the top local family; Huangxing was reduced to a wasteland due to the resource war a hundred years ago, and became a place of exile for the nobles of Tianshu Star to expel "unfortunate people".
Su Wanzhu, the bane of the Su family who was expelled from the Su family, struggled to survive on the apocalyptic wasteland planet "Desolate Star" for five years, learning poison-making, fighting, calculation and other ruthless skills. He was recalled to the Tianshu planet due to the struggle for the Su family's heir. On the surface, she pretends to be weak and pitiful, but in fact, she uses the ruthlessness to survive in the wasteland to fight back against the jealous real daughter Su Lianyue, the hypocritical stepmother Zhou, the scheming sister-in-law Lin, and other enemies in the house. At the same time, she develops a relationship with Lu Zhao (Bai Qiehei), a member of the royal family, and reveals the truth that the "disaster destiny" is designed by Zhou. Eventually, she becomes the head of the Su family and lives happily with Lu Zhao.
