Lin Wanwan, a no-nonsense PhD in biological sciences, is sent to the afterlife by an injection from an agent. By a twist of fate, she transmigrates into the body of Lin Wanwan, a concubine-born daughter of an ancient prime minister. The moment she opens her eyes, she’s faced with a fearsome mother-in-law and sister-in-law.
Before she can even fully process that her branch of the family has been driven out to the countryside, a woman arrives, hauling two children on a door panel and demanding they acknowledge their kinship.
A woman with consumption, children gaunt with hunger, and neighbors with bad intentions: she has no choice but to roll up her sleeves and fight heaven, earth, and charlatans alike. If Lin Wanwan can alter human genes, what’s stopping her from turning the whole world upside down?
But... the man returning home in glory amid a noisy procession... is he her husband, who died in battle?
