Shen Yi drew a portrait of a child abducted in his office. Du Cheng stared at him intently, thinking of the past. After Lei Yifei was killed seven years ago, the unruly Shen Yi showed his ability to draw a three-year-old man in front of the capital. The emotional capital asked Shen Yi to draw the face of a mysterious woman, but Shen Yi, who couldn't draw it, was forced to worry.

Ducheng accused Shen Yi of painting a portrait of a mysterious woman and killing a good policeman who served the people. Shen Yi's eyes went red when he learned the truth. He tried to draw something impatiently, but he couldn't draw it after he put pen to paper. When Du Cheng left the interrogation room, he said seriously that Shen Yi's paintings would kill people, and he was not worthy to pick up the brush again.

Shen Yi came to the river alone and wanted to jump into the water to experience the abnormal state of drowning. He wants to retrieve his memory and draw a portrait of a mysterious woman. Du Cheng, who followed all the way, stopped and comforted Shen Yi. He told the whole story of the portrait and drowning.
