The little Taoist priest Fei Dun was born with five shortcomings and three shortcomings, and was extremely unlucky. He practiced Taoism alone in Xiaogushan, accompanied by mice every day. With the help of the system, he studied hard and practiced hard, and gradually mastered the Taoist secrets left by his master. From then on, he started to enlighten the villagers, punish evil and promote good, uphold justice, and make fun of the nonsensical Taoism.
