Modern forensic pathologist Li Qiu dies suddenly from overwork and transmigrates into the body of Li Qiu-niang, a widow in ancient times. Her husband, Xue Jingyuan, is killed in battle, leaving her to support the Xue family with her own abilities. She hunts to provide for the household and protects her parents-in-law, younger siblings, and a pair of fraternal twins. Unexpectedly, Xue Jingyuan returns from the dead as a great general, bringing along Gu Ruo, the daughter of a powerful family. He insists on divorcing Li Qiu-niang and taking the children away. Li Qiu-niang decisively agrees to the divorce, and the entire family leaves the clan. By chance, she awakens a mystical seashell space containing spiritual farmland and a spiritual spring. She purchases a residence and an estate, establishes the Hundred Herbs Pavilion, and uses medicinal herbs to stir up the world of the capital's powerful families. Facing the relentless schemes and oppression of her former husband and Gu Ruo, Li Qiu-niang relies on her intelligence and abilities to protect her family, build her business, and secure their livelihood, carving out a world of her own amid the chaos of troubled times.
