Feng Muhan, the cold-faced and ascetic prince of Shengjing, was plotted and drugged, and was beaten up by the nine-tailed fox princess Hu Xiaojiu who descended from the sky in the hot spring. In order to save the endangered fox tribe and find high-quality human offspring, the little fox immediately locked eyes with him and wanted to have cubs. She disguised herself as a Taoist priest and stayed with the prince. She was proficient in catching ghosts and behaving cutely, and was able to seduce the ascetic prince repeatedly. However, Jiuwei's identity was accidentally exposed, and the vicious female Song Feiyue took the opportunity to frame her. The fox clan leader's conspiracy to usurp the throne followed one after another, and the human-monster took different paths, and the two were in many crises.
