Liu Xiaoye, who was raped, sat quietly in the ward to observe a snail, and Shen Yi saw her as a doctor in a white coat. Liu Xiaoye thought that Shen Yi was going to examine her, but Shen Yi just chatted with her about snails. Shen Yi, who came out of the ward, already had the answer in his heart, and then Xiao Liu relayed Liu Xiaoye's description of the strong prisoner to Shen Yi, and Shen Yi drew many facial features according to the description. Xiao Liu couldn't understand Shen Yi's thoughts. Shen Yi said that much of Liu Xiaoye's observations came from perception, focusing on details and physical dimensions, so under the effect of hallucinogens, her description would be more vague. Xiao Liu saw that these facial features were related in many perspectives, and Shen Yi asked her to classify these facial features. In the end, the two pieced together three incomplete faces, and found that what Liu Xiaoye encountered was probably Lun J. With the encouragement of Shen Yi, Xiao Liu picked up the brush and completed the three portraits according to the skull anatomy. When teaching Xiao Liu's portrait, Shen Yi thought of his painting enlightenment teacher Xu Yiduo.
The young Shen Yi was graffiti on the street with oil paint. After seeing it, Xu Yiduo offered to teach Shen Yi how to draw. Shen Yi felt that learning to draw was very unfree, and Xu Yiduo said that he could bring Shen Yi real freedom. Xu Yiduo taught Shen Yi the painting skills hand in hand, and brought him to feel the vitality of colors, so Shen Yi had a deep affection for Xu Yiduo.
Director Hu found three male students who were in the same school as Liu Xiaoye based on the portrait painted by Xiao Liu. Under the interrogation, the three explained the process of their implementation of Round J. The loner Liu Xiaoye was targeted by the three people who had been premeditated for a long time. After the party that day, the three took away the drunk Liu Xiaoye and drank her obedient water, and then carried out a round J. After committing the crime, the three There is a purpose to clear the traces of the scene.
Director Hu found that the portraits of these three people were a little less than the original three-eye portrait, and Shen Yi also noticed this, and found the shape of a butterfly by smearing out the facial features of the portraits. This is a portrayal of Liu Xiaoye's memory. Shen Yi wanted Liu Xiaoye to see it. Liu Xiaoye's mother looked at Butterfly and remembered the past many years ago.
Liu's mother was busy with work and could not pick up Liu Xiaoye from school on time, so she enrolled young Liu Xiaoye in an interest class. Liu Xiaoye was molested by the male teacher while observing butterflies in the interest class. Liu's mother was afraid that this would ruin Liu Xiaoye's reputation, so she did not speak up.
In order to understand Liu Xiaoye's heart, and to prevent more girls from being poisoned, Shen Yi persuaded Liu's mother to cooperate with him in investigating the matter. Shen Yi found the male teacher and brought him to justice. He also returned the butterfly specimens collected by the male teacher to nature. Perhaps in this way, those injured souls will be healed.
Xu Yiduo, the enlightenment teacher of Shen Yi’s painting, went to the police station to find him. Du Cheng asked Xu Yiduo to wait for Shen Yi who was out in the reception room. Xu Yiduo proposed to see Shen Yi’s paintings. Shen Yi is the best and most gifted student Xu Yiduo has taught, so Xu Yiduo regrets that Shen Yi gave up art and painting. He wants Shen Yi to become an artist instead of working in the police station. a portrait artist. Du Cheng bluntly said that Shen Yi is not an ordinary portrait artist, because he can see a person's heart through his appearance, and he has made great contributions in several previous cases. Du Cheng knew that Shen Yi loved the police profession very much, and he persuaded Xu Yi to respect Shen Yi's choice more.
After learning that Xu Yiduo had been here, Shen Yi called Xu Yiduo, but the news he got was that Xu Yiduo and his wife drowned at the beach. After He Mingyue's autopsy, it was confirmed that Xu Yiduo and his wife committed suicide. Shen Yi looked at Xu Yiduo's body and couldn't accept this fact.
Shen Yi found the key under the flower pot at the door of Xu Yi's house according to habit, and Du Cheng and Shen Yi walked in together. Looking at everything familiar in front of him, Shen Yi thought of the care and concern that Xu Yiduo and his wife treated themselves as sons. In the studio, Shen Yi saw his own paintings when he was young, and also saw a painting that he burned seven years ago.
