Folk Custom: It Starts with the Corpse Chasers in Western Hunan

Before his death, my grandfather left behind two things: a broken notebook and a copper bell that couldn't ring. Another sentence: "Don't go to Shenxi Village." Shen Mo has been a good grandson for twenty-three years and has never been there for a day. Until his university professor mysteriously disappeared in Shenxi Village. Talismans are posted on the doors of every house in the village, and no one dares to open the door after dark. The village chief's son lost his soul and lay on the bed with his eyes open and his pupils dilated. Grandma Wang said that her grandfather did not die of illness - he gave his life to the cave in the back mountain. What's in the cave? The Shen family has kept a secret for three hundred years. There is a man lying in the sarcophagus. Three hundred years ago, in order to save a city, he swallowed all the evil spirits into his stomach. The ancestors of the Shen family sealed him here and promised to release him when the evil spirit was gone. For three hundred years, every generation of the Shen family has fed themselves to him. Now it's Shen Mo's turn. He touched the copper bell in his pocket. This time, it rang.
