It tells the story of Ning () going to the county to collect accounts. In case of heavy rain, he hid in the legendary Lanruo Temple for one night, but was rejected by Taoist Yan Chixia (noon horse ornaments), so he would rather sneak into the temple.
In the evening, Ning was attracted by the sound of the piano and met the girl Nie (played by Joey Wong). Nie's sudden murder saved Ning's life. Nie thought she was honest and kind, and gradually developed love, but Yan Chixia stopped her. Ning mistakenly thought that Yan Chixia was the murderer and wanted to escape with Nie.
The Tree Demon (Liu Zhaoming) forces Nie to kill Ning, but Nie always refuses. So grandma ordered the demons to kill Ning and Nie, and Yan Chixia appeared to save them. At this time, Ning learned that Nie was a ghost and was controlled by her grandmother because her bones were abandoned in the wilderness. Every night, she looks for strong men to absorb yang for her, so as to prolong her life.
In order to avoid being humiliated again, Ning Cai Chen promised to send his bones back to the countryside for burial and reincarnation. Unexpectedly, Nie Xiaogan was robbed by the old monster in hell and became his wife. Yan Chixia succumbed to Ning's pleading, decided to attack again and was finally rescued.
