Episode 4

At the case summary meeting, Du Cheng arranged for the police to visit Ren Xiaoxuan's classmates as soon as possible to try to get clues.Ren Xiaoxuan's skull was replaced after the corpse turned into bones, so it is crucial to confirm the age of the skull replacement as soon as possible.After hearing this, Shen Yi hurriedly left. He found Zhai Lanxin's home based on the paintings in the school studio.Zhai Lanxin's family has an unfinished line painting. Zhai Lanxin likes the hair swaying in the wind very much. Shen Yi thinks it is very clever.All the art students in the No. 7 Middle School had skull copy assignments. Shen Yi wanted to find out the time when the skull was replaced by checking these assignments. Finally, Shen Yi determined the time when the skull was replaced.

The clues were gathered and it was revealed that Ren Xiaoxuan's skull was replaced six years after her disappearance. Shen Yi pointed out that only art students and art teachers could enter and leave the art room at will.Ren's mother brought a diary that was disguised as a Chinese document by Ren Xiaoxuan. After reading the diary, Du Cheng discovered that Ren Xiaoxuan had been bullied and molested. Li Han interpreted the diary from a girl's perspective. The diary recorded a boy whom Ren Xiaoxuan loved..Shen Yi saw the back of a boy drawn by Ren Xiaoxuan in his diary, which was exactly the same as the back of the boy drawn on Ren Xiaoxuan's desk.

Du Cheng handed Ren Xiaoxuan's diary to Shen Yi and asked him to make a portrait. Shen Yi disliked Du Cheng for not studying it carefully enough. Du Cheng was dissatisfied, but he read the diary seriously again in private. The diary recorded what happened to Ren Xiaoxuan.During the molestation process, Du Cheng discovered that the person who molested Ren Xiaoxuan was probably her art teacher at the time, Zhang Zipeng.Du Cheng checked the teacher's files and found that Zhang Zipeng was expelled for molesting a female student, just after Ren Xiaoxuan's skull was exchanged.

Shen Yi was sitting on the playground looking for inspiration. He tried to draw a portrait of the boy through Ren Xiaoxuan's description. Just when he seemed to be about to touch the boy, Du Cheng suddenly interrupted him.Du Cheng took Shen Yi to find out the situation from Zhao Zipeng, who was renamed Zhao Tingtao. He is now running a gallery.Zhao Zipeng was receiving guests, while Du Cheng and Shen Yi were wandering around the gallery. Shen Yi found that every oil painting in the gallery was marked with a number of sales that should not have occurred, and there was also something wrong with the painting time and artist recorded on the painting.

Shen Yi suspected that what Zhao Zipeng was selling was not paintings. Du Cheng took Zhao Zipeng back to the police station for interrogation. Zhao Zipeng confessed that he organized the prostitution, but denied that he was the one who killed Ren Xiaoxuan.When Zhao Zipeng molested Ren Xiaoxuan, he was interrupted by a male classmate. Shen Yi asked about the boy's appearance, but Zhao Zipeng couldn't remember it at all.

Shen Yi asked Zhai Lanxin to ask about the situation, but Zhai Lanxin didn't know that Ren Xiaoxuan had a boyfriend. Shen Yi asked Zhai Lanxin to draw a portrait based on the description in Ren Xiaoxuan's diary.Zhai Lanxin talked about the frequent gatherings in their art rooms. Shen Yi wanted to organize a party to see if the boys related to Ren Xiaoxuan were among them.The opportunity venue was arranged at the school. When preparing, Shen Yi asked Zhai Lanxin why she didn't go abroad for further study. After all, she could achieve higher achievements with her artistic attainments. Zhai Lanxin asked Shen Yi why she wanted to work as an iconographer in the police station. Shen Yi only saidI like a stable job and stable income.Zhai Lanxin does not want to be surrounded by too many desires. Teaching in a school allows her to bring art to every student who likes painting.

Everyone was very happy at the party. Zhai Lanxin proposed playing games, and she also offered suggestions. In the end, everyone picked up chalk and drew characters on the blackboard. This character introduction came from Ren Xiaoxuan's diary.Shen Yi and Du Cheng observed everyone's reactions in the dark. One of the boys named Tian Lin caught their attention, and Tian Lin was taken back to the police station.Tian Lin confessed that he had read Ren Xiaoxuan's diary. Before that, he always thought that Ren Xiaoxuan liked him. At that time, Ren Xiaoxuan often watched him play basketball on the basketball court. The two met on a rainy April Fool's Day.Tian Lin found out that he was in love and began to bully Ren Xiaoxuan. These were all recorded in Ren Xiaoxuan's diary, but Tian Lin never knew who Ren Xiaoxuan liked.

Shen Yi fell asleep in the car again. When he arrived at Shen Yi's house, Du Cheng woke him up.Shen Yi went home and looked through Ren Xiaoxuan's diary again. He found that the April Fool's Day recorded in Ren Xiaoxuan's diary was a sunny day. So why did Ren Xiaoxuan lie in his diary?
