The "Illustrated Book of Crime Hunting" has been aired for more than half of the time, and the woman who asked Shen Yi to draw the portrait of the Thunder Team seven years ago is slowly coming back to the surface. While monitoring He Hong, He Hong went out late at night. In order to make up for the regret of the first police call, Li Junhui chose to follow He Hong himself. During the tracking process, Li Junhui was discovered by He Hong and was killed.

When the forensic doctor examined Li Junhui's body, he found that Li Junhui's knife edge was very similar to the knife edge where Lei Dui was killed. In other words, the current He Hong is most likely the murderer who killed Captain Lei seven years ago.

In addition, from the conversation between Shen Yi and He Hong, He Hong said, "The paintings you painted are really like me." At this time, the camera showed the portraits on the wall. One is the current portrait. He Hong, next to him is the woman in Shen Yi's memory.

This scene is a bit scary to think about. Perhaps He Hong said to the woman in Shen Yi's memory, "What you painted is really like what I painted."

When Shen Yi recalled, he thought of the conversation between himself and He Hong. At this time, Shen Yi suspected that He Hong was "M", the woman who asked him to draw the portrait.

Shen Yi has always suspected that He Hong had plastic surgery, which means that the real He Hong has been killed long ago and the current He Hong is fake. In addition, Xiao An's biological father said frankly, "I always thought that she didn't want to "Recognize me, it turns out that she really doesn't know me, she is just using me." This also confirmed that the current He Hong is fake.

In addition, when searching He Hong's home, traces of Lei Dui's case were found, which also hinted that He Hong was related to Lei Dui.

At the beginning of the series, the woman looking for Shen Yi's portrait was given a shot of red lips, which coincided with the shot of He Hong's red lips when she transformed.

In Jia Hehong’s memories, her original appearance was revealed, and she also had red lips. This means that Shen Yi had already painted the look of the murderer, but the murderer had already had plastic surgery and used another person. Live with one identity.

As for why Jia Hehong gave Shen Yi the list, maybe Jia Hehong was a victim herself and became a perpetrator in order to survive. Her husband was an accomplice to spy on him, so she took advantage of Xiao An. She wanted to use this opportunity to completely destroy the organization that changed the trajectory of her life.
