The Fake Taoist Priest Got into Trouble with the Real Ghost

A seven-yuan fake sword and a talisman cut out of A4 paper, I cheated for five years without falling over—until the ghost knocked for the fourth time. Li Xuan has been a fake Taoist priest for five years, traveling around the world by hunting for magical artifacts, and follows sixteen rules to ensure safety. Article 1: No night orders will be accepted. There was no problem with the rules until an old lady came to him to exorcise evil spirits. The ghost is coming. Not midnight - three o'clock in the afternoon. After knocking three times, he said: "Your Taoist priest is fake." Then a fourth knock. There is no fourth blow in the rules.
