Chen Kaiwen, a master of Qimen Dunjia (an ancient Chinese metaphysical art), completed his training and left his master, who gave him three strict rules to follow: first, form no alliances; second, take no wife; and third, never set foot on Fengming Mountain. However, by a twist of fate, Chen Kaiwen ends up breaking all three rules, which leads him into a series of dangerous crises. His first major challenge comes from the female lead, Bai Hui. When she first meets Chen Kaiwen, she is already engaged to Sun Qiang, a corrupt and ruthless local tycoon. However, Bai Hui is plagued by persistent nightmares, prompting her to seek out Chen Kaiwen's help. In the process of resolving her issue, Chen Kaiwen begins to uncover more and more dark secrets hidden behind Sun Qiang’s facade.
