Di Shu, a detached sword cultivator empress, despised the bloodline of her demon king husband Bai Mo and their half-demon son in her past life, single-mindedly pursuing the Dao, only to be assassinated by her demonized son upon ascension. Reborn to the moment her son was on the verge of death, she consumed her vital essence blood to save him and accepted Bai Mo's company along the way. During their journey to seek medicine, the family of three met the medical cultivator Yan Susu, joining forces to fight villains and gradually growing warm affection. Di Shu meticulously cared for and taught her son, helping him avoid the fate of demonization in his past life, and when resisting a beast tide, her son awakened his ancient white tiger bloodline. Bai Mo's long-lasting gentle guardianship melted Di Shu's frozen heart. Di Shu transcended her tribulation to ascend to the immortal realm, but renounced her divine position to return to the lower realm and stay with Bai Mo. Years later, their son succeeded the throne as demon king, becoming bickering enemies with Yan Susu's daughter.
