Xu Changan, a son-in-law who was ridiculed by the world, did not know that he had the blood of ancient gods and demons sealed in his body. His wife Su Yutong is the cool president of the Su Group, but his three-year-old daughter Su Xiaonuan is his only weakness.
In an accident, Xu Changan awakened his dormant power to protect his daughter, but found that the world was far more complicated than he imagined - there were undercurrents in the world of cultivation, the Demon Sect was ready to move, and his wife Su Yutong was inextricably linked to the Demon Sect.
When the father confronts the witch, when the forces of good and evil are entangled in the blood, Xu Changan must make a choice: to cut off this marriage that should not exist, or to protect this family in his own way?
The four secret realms were opened, and the forces of the five realms gathered together. A son-in-law who was regarded as a waste became an anomaly in the entire world of cultivation - because he not only wanted to conquer the world as a daddy, but also wanted to let everyone understand what it means "my daughter is invincible in the world"!
