In the meantime, jie-bai has brought back duan, who is suffering from a strange pain. . He has rented a room in the basement and discovered that duan is addicted to hallucinogens, which are a painkiller. He tells .bai that he found this in his pocket earlier, and duan has been addicted to it ever since. He says that he saw .shanshan in a dream ten years ago, and that he tried to save her, but that he lost her again. This time, when he was about to approach her, she would run away, and the whole world would begin to dissolve. This is the same case duan had, he says. The key to this case is in the photograph, which shows the victim of the crime. Duan and the victim both died from spontaneous combustion years later. The police need to get duan back to the station, but he says that right now the "most important thing" is to fix his brain.
