Wu Hongda's autopsy report came out, and the inspectors said that Wu Hongda had scars on his chest, which was most likely a homicide. The inspector learned that Linglong's concierge had seen Jiang Yu come to Linglong on the day of the incident, and Rainbow thought that Jiang Yu must have killed his father. The police detained Jiang Yu, who said he had an alibi. He did visit Linglong that day, but Wu Hongda personally saw him to the door when he left, and had lunch with the director of the police department that day. Jiang Yu's two alibis were confirmed, so the police had to let Jiang Yu go.
Zhou Shaotian can't see the past. He let the rainbow leave Linglong. Rainbow said that if she left, she would be trapped by Jiang Yu. She will stay in Linglong and find out the secret of her father's murder.
