Lin Jiuge, a 21st-century genius of traditional Chinese medicine, transmigrates to the Nine Profound Continent after an explosion in her laboratory and takes over the body of the Lin family’s legitimate daughter, a good-for-nothing young lady in the Kingdom of Cangwu. Unable to cultivate profound energy, the original owner was cast aside by her family and sent to a small border town. After awakening the Medicine King Cauldron, which contains the Classic of a Hundred Herbs and an ancient medicinal herb treasury, she discovers that she carries the bloodline of the Medicine King. Her profound meridians can control the “qi of life and death,” making her capable of both healing and poisoning.
