Du Cheng took people to Eric's home to investigate, and happened to meet Mr. Xue, who teaches art, to send Jose home. Eric hoped Du Cheng wouldn't let his daughter MuXiaoAn know about MuWei's disappearance.

Li Han found Li Zhiqiang's online ticket purchase records in Muwei's computer. After visiting Du Cheng, he learned that Li Zhiqiang had been paralyzed for many years and his identity card had been sold by his mother. Eric's computer screen saver is very bright in color, and the color contrast of TV is also very abnormal. Shen Yi thinks Mu Wei is color blind.

When the robbers fled, they crossed the road to observe the traffic lights in the same state as normal people, so the robbers must not be Mu Wei, who is color blind. Shen Yi realized that the robbers deliberately copied the Jiufu jewelry robbery into Huachang jewelry robbery, and deliberately left Mu Wei's blood in the Jiufu jewelry robbery, just to frame the case on Mu Wei.
