Su Wangyan, a close disciple of the master of metaphysics, started an unpopular live broadcast of "Talking about Mysteries" to pay for his living expenses because his master was traveling around. He specialized in telling stories about old graves and Feng Shui jokes. After being accidentally asked by fans to ask for help "the haunted house is haunted", he was forced to live broadcast to exorcise the evil spirits. With his funny words (scold the evil ghosts until they suspected ghosts), down-to-earth metaphysical operations (using spicy sticks as offerings, using square dance speakers to play "The Most Dazzling Ethnic Style" to destroy evil spirits) and solid skills as a teacher, he actually "purified" the haunted house into a check-in spot for Internet celebrities.
