Five hundred years ago, the immortals and demons fought each other. Master Zihua and the Emperor of Heaven worked together to destroy the fox demon clan. Five hundred years later, the master rescued the nine-tailed fox demon Xiaojiu who was fleeing. Xiaojiu repaid the favor by worshipping Zihua as his master. Zihua used the Hunyuan Bell to seal his demonic aura and kept it by his side. Xiaojiu had deep feelings for Master Zihua. On Zihua's birthday, he made a whip out of the tail of General Weiting's mount, the sea-crossing beast, and gave it to Zihua. Unexpectedly, General Weiting reported to the Emperor of Heaven, who ordered the capture of the fox demon Xiaojiu. Zihua cut off one of its tails to save Xiaojiu. Cutting off his seven emotions and six desires, he descended to the mortal world to survive the catastrophe. In his second life, Xiaojiu used the Hunyuan Bell to find the reincarnation of Master Zihua, but mistakenly recognized the mortal General Hua as his master. In order to stay by General Hua's side, Xiaojiu killed Liu Sheng. After Liu Sheng died, Xiaojiu's memories returned. Xiaojiu, who had recovered his memory, was in great pain. It turned out that the person he had been looking for was killed by himself. On the other side, Hua Rong died of depression because of Liu Sheng's death.
