Zhang Ling, a seemingly ordinary college student, whose biggest hobby is eating chicken legs in the dormitory. No one knows that he is a hidden heavenly master who can only be seen in Longhu Mountain for a hundred years. When the campus was haunted by ghosts, rich businessmen prayed to gods, and evil cultivators danced wildly, and everyone thought they were going to kneel down to beg for mercy, Zhang Ling silently took out the talisman and gnawed on the chicken leg and said: "Don't panic, I specialize in treating all kinds of dissatisfaction." From then on, masters from all walks of life broke defenses, liars went crazy, and supernatural events became jokes. This is a comedy story about a heavenly master who uses rules and words to turn the world of metaphysics upside down.
