Set in ancient China's oppressive feudal society and a world of clandestine family elixirs, this period suspense drama explores gender transformation, intertwined destinies, and the quest for self-identity.

Meanwhile, Xiang Wuyou, torn between familial obligations and forbidden desire, embarks on a profound journey of self-reckoning.)
