Transmigrated woman Su Wan, in order to avoid love poison, accidentally provokes the cold immortal lord Mu Yuan, and the two accidentally form a bond. Mu Yuan, out of love driven by fear, sets up a scheme to imprison Su Wan, causing her to escape and fake her death to get away. Two years later, Mu Yuan is heavily injured and loses his memory, and Su Wan carries a huge amount of compensation to go far away and enjoy a salted fish life. However, Mu Yuan returns strongly after recovering his memory, exposing his half-demon identity to protect Su Wan's safety, and finally publicly inherits the lineage at the sect grand ceremony, clearing up misunderstandings and officially becoming dao companions.
