During the Qin and Han Dynasties, the captain Wang Sheng and the gentle and virtuous "righteous and courageous true wife" Pei Rong were a loving couple known to everyone in the town. Captain Wang Sheng led his army to rescue a stunning woman from a fierce battle with bandits in the Western Regions and brought her back to Jiangdu Palace. Unexpectedly, this girl was transformed into "Jiuxiao Beautiful Fox" Xiao Wei in human skin. Its skin must be maintained by people's hearts, so Xiao Wei's invisible assistant Xiao Yi, a demon built from a desert lizard, kills people every few days and takes their hearts as offerings to Xiao Wei to show his love for Xiao Wei. As a result, Jiangdu City is plunged into terror. Xiao Wei fell in love with Wang Sheng, the leader of the Wang Family Army, because of his bravery and handsomeness, and kept using sorcery to seduce Wang Sheng, hoping to replace Wang Sheng's wife Pei Rong.
