The pig demon and the fox demon were ordered by their master to go down the mountain to practice "cannibalism", but the first person to eat turned out to be a Taoist priest. Unexpectedly, they were deceived by the Taoist priest, put into the Qiankun Bag, and sold as wild boars and wild foxes... The Taoist priest deceived them again and became his own demon servants. They followed him around the world to slay demons.
The pig demon Zhu Xiaoxian is a bit silly and relies on his senior brother, the fox demon Bai Yulang, to take care of him. The Taoist priest Zhang Ziluan is scheming and lustful. He is a man of both sexes. Even when catching demons, he does not take the usual path. The combination of two demons - two fathers and one daughter? Love triangle?
