Entering the mountains for the first time Lin Wanqiu came to a remote mountain village as an intern reporter to investigate the strange occurrence of lights turning on in an ancient house in the middle of the night. She stayed at the village party secretary's house, and on the first day she ran into a conflict between the contractor Wang Jianguo and the local ruffian Er Gouzi. Wang Jianguo was particularly attentive to her, which made her suspicious. At night, she sneaked around the ancient house, heard voices inside, and saw Er Gouzi moving boxes in and out. Just as he was about to get closer, someone suddenly covered his mouth and dragged him into the grass. It was Wang Jianguo. He said this place was dangerous and told her to mind her own business. Lin Wanqiu broke away from him, only to find a faint blue light coming from the crack in the door of the ancient house, like a will-o'-the-wisp. ## Volume 2: Undercurrent Lin Wanqiu visited the elderly in the village during the day and learned that the owner of the ancient house, the Ouyang family, disappeared overnight, leaving only a crazy old lady.
