Twenty years into the apocalypse, the base where Shi Yunfan lives is besieged by zombies. Everyone exhausts their powers, but still cannot save the base. The base leader tells the heroine, a level-ten plant-based ability user, to escape with all the children. But things don't go as hoped: the Zombie King catches up with them. To protect the children, the heroine chooses to die alongside it.
When she wakes again, the heroine has transmigrated to the 1970s in another world, with an exceptionally handsome, well-built man lying on top of her. Having been single since birth for over thirty years, she decides to enjoy the man who has practically landed in her lap.
Afterward, the heroine searches through the original owner's memories and learns that the whole thing was a trap. Using the pocket dimension she obtained from the Zombie King's core, she turns the tables.
After the heroine is sent to the countryside, she reunites with the male lead. He gradually realizes that she is the woman he spent one passionate night with, and that the child she is carrying is his. Through the male lead's tireless efforts, she slowly accepts him, and the two begin a life of hunting down spies and thwarting petty schemers.
In 1977, the heroine gets into a university of traditional Chinese medicine. With the help of her pocket dimension, she becomes a leading authority in the field.
