In the middle of the night, huanhuan's boyfriend, ximenkang, arrives to check on his girlfriend. He is shocked to find that she has lost consciousness and is in danger of dying. He decides to go to find a doctor, who is a medical student, to treat her. He tells the other members of the team that he has stayed in Shanghai for only three days, during which time he has never been around a tower or a convention center. He asks if they can tell him about the situation at the convention center, and he says that he feels like this fever "came out of nowhere" . He then tells the others about the dungeon they have just escaped from. He says that ding shin wa itsumohitotsu, or "there is always one truth" , is the truth about a small hostel that contains the remains of innocent victims and hides the murderer. He also tells the story of how huan Huan's younger sister, guyuhuan, used to call him "stupid rocky," which she later told her parents. She thought the problem was "stupid" because it was not a pleasant nickname, but she later got rid of the word because she thought it was romantic.
