With the help of Brother Yun, the master of the Tian Shi Hall, they learn about the demon-protecting trajectory of Tianyin's father, Song Daitian.
When returning to Yongning Village, Hu Ba is once again chased by the Demon King. While on the run, he befriends a gambler named Tu Sigu and another monster, and the three of them live life together.
At the same time, there are rumors of a huge bounty for the demon king Hu Ba. Many forces stirred up a storm in the town of Qing Shui to steal Hu Ba.
In the nick of time, Tianyin and Xiaolan find Hu Ba through Tian Shi Hall and escape the danger together.
But an even bigger conspiracy is waiting in the wings.
