When Chen Yan, a college student, returned to his hometown in the mountains during the Qingming Festival, his grandma warned him: Don't answer when someone calls your name at night; don't take the dead person's message if they ask you to.
He didn't believe it until the night after the power outage, when a woman outside the window actually whispered his name. He only said one sentence, and the things on the slope of the ancestral grave followed this sentence and recognized the door.
From that night on, the evil spirit that had been raised in the grave, the strange voice that could imitate the speech of familiar people, the corpse shell hiding the life-preserving talisman, and the residual breath related to his father, all crawled out of the earth little by little. Only then did Chen Yan realize that he had not accidentally run into evil spirits, but had returned to the debt that the Chen family had long owed and would have to repay sooner or later.
