Ye Xiaofan, a young farm boy, accidentally obtained a mysterious spiritual root and broke into the legendary spiritual realm. He accidentally rescued the demon fox Su Ling'er and formed a temporary team with the spiritual beast Fat Tiger. The three of them were catching monsters and solving mysteries, laughing and joking, but they got involved in a dispute between two major forces in the spiritual realm. By chance, Ye Xiaofan got acquainted with Chu Yu, an old Jianghu in Lingyu. Under the pursuit of the Black Crow forces, he worked together with his partners to resolve the crisis. When the catastrophe is imminent, Ye Xiaofan and his partners use whimsy and positive humor to "counter" the enemy, promote a new order in the spiritual realm, and find the meaning of growth and the responsibility of family and country.
