Who is the murderer? Who's Li Weiyi?

Li Weiyi played by Wang Xin should be the murderer. The hero 180CM has the same eyes and ears as the murderer in the first episode. Why does the screenwriter want mental abuse? Where's Cao? Where's the story line? Because to test Shen Yu's mental illness, not everyone expects the truth. For example, Cao's son also conforms to the rhythm of the whole story.

Shen Haiyang recognized the murderer as his colleague. This man is Li Weiyi. After years of working together, Li Weiyi has more opportunities to contact this sensitive drug-muscle relaxant. Shen Haiyang followed him to the studio. I still remember staring at the latest photo for a long time in front of the studio because there was a red fingerprint on it. Perhaps it was because of this fingerprint that Shen Yucai changed his mind and wanted to be a forensic doctor.

Looking at the cast, the names of juvenile Shen Haiyang and juvenile Hu Shanquan are next to each other, indicating that they have known each other since childhood. In addition, the middle-aged crew only has the name of Shen Haiyang, so the middle-aged Hu Shanquan should be renamed. So far, the only role that has not played the leading role is Li, so he is probably the renamed Hu Shanquan.
