Chen Du lived with his master in the mountains for ten years, learning to draw talismans and memorize mantras, but he always thought that these were just skills used by old people to make a living. Until the master received a mysterious letter late one night and left in a hurry, leaving only half a warm jade pendant and an old book.
With doubts, Chen Du followed his master's last instructions and came to the "Lao Zhou Paper Shop" in Jiangshi Old Street. Here, he gradually discovered that the old book left by his master contained unknown records and special methods. Zhou Ping's grandfather and grandson also seemed to know about their master's past.
He began to come into contact with some "strange events" that ordinary people avoid: unexplained regular abnormal noises in old communities, disturbing late-night movements in abandoned factories, and certain "special groups" with abnormal behavior... Each commission is like a puzzle piece, pointing to the truth about the master's disappearance, and slowly uncovering another side of the city that has been hidden for a long time.
Chen Du decided to use the methods he had learned in the past ten years and recorded in the book to help those who were troubled and at the same time look for traces of his master. In this city where modernity and tradition intersect, he gradually understands that some ancient wisdom has never gone out of style, just waiting to be picked up again by those who need it.
