The black man who appeared at the end of "Hunting for Crime Picture Book" broke into Shen Yi's home and looked through Shen Yi's photo album. In that photo album, there are portraits of people involved in each case. Finally, the black man cut Shen Yi's self-portrait with a knife, revealing a black and white background.
This ending left enough attractive foreshadowing. There should be a second season in the Picture Book of Hunting Crimes. Otherwise, the last appearance of the black dress person will be redundant.
There are two possibilities for the identity of this man in black. The first one is easy to understand, that is, the man in black is the big boss of the behind-the-scenes group. The man in black looks like a man, but it doesn't rule out that he is a daughter. He should be a figure who has already appeared. Chen Zhou is just one of his pawns.
This can also be proved in JC-T's album of playing with Shen Yi, that is, other people's portraits are normal, except the portrait of Chen Zhou, and Shen Yi drew a chess piece around the portrait. Therefore, this detail implies that Chen Zhou is just a pawn sacrificed by the mastermind behind the scenes to protect his own safety and terminate the police investigation.
The men in black in Hunting Crime Picture Book went to Shen Yi's house this time, on the one hand, to see if Shen Yi had any other evidence, and on the other hand, to provoke and intimidate Shen Yi. He helped Du Cheng and caused great losses to the criminal group headed by him, especially Chen Zhou, who is the boss of a technology company. He was uncovered by Ducheng, Shen Yi, and the criminal group suffered heavy losses.
Therefore, the men in black came out to teach Shen Yi a lesson and cut Shen Yi's paintings with a knife, which was threatening Shen Yi. This knife, he wants to draw it on Shen Yi's face, not just painting it.
Doubts in the play:
At the same time, men in black may have another identity, and that is Shen Yi. Shen Yi played by JC-T is a decent figure in the whole play, but there are still many mysteries about him. Why does he like sleeping as soon as he gets on the bus? What happened to him when he was a child? Where did he go in the seven years since he disappeared? What happened?
After the men in black tore up Shen Yi's self-portrait, another self-portrait was formed, much like Bourne's. When Bourone was in his prime, he painted this incomprehensible self-portrait. Many years later, Braun had an argument with others in a hotel. In the fight, his eyes were injured by a broken beer bottle, and finally he had to remove his eyes and become what he looked like in the portrait.
