There are a lot of indecent videos on the CD in Liang Yi's Secret Room. All the women in the video had cosmetic surgery with Liang Yi. Some of them are obsessed with J, and some are willing. Five of these DVDs are missing, and Zhang Bureau thinks that finding out the women recorded on these five DVDs may be one of the murderers.

Du Cheng asked Liang Yi's secretary to match the photos of indecent video screenshots with their photos before plastic surgery. The secretary only took over some patients, but she remembered that a girl named Elvin had made enemies with Liang Yi because of the failure of plastic surgery.

Shen Yi once mentioned that the woman in the surveillance video outside the plastic surgery hospital was probably a plastic surgery failure, so Du Cheng quickly took Jiang Feng to find Alwen.

Elvin's mother gave them a call. When Du Cheng found Ai Wen, he found that Alwen, who had failed in plastic surgery, was unconscious. Now she has been living in a mental hospital.
