Yu Chihong drove a black Lexus luxury off-road vehicle, with a large amount of leather wrapping and mahogany trim, giving the interior of the car a mature atmosphere. The ride is spacious, and the seat cushions and backrests are very generous. Qiao Yan leaned comfortably on the back of the passenger seat and stretched her legs.

On the road, Lieutenant Chi Hong briefly explained the situation to Qiao Yan. The Da Vinci Academy of Art hosted the first national college student micro-film festival, and began to solicit works half a year ago, and soon after, the organizing committee of the micro-film festival received an HDV videotape called "Beautiful Game", which depicts a young girl walking around the room and posing in various poses. The girl was wearing a beautiful dress with bright colors, but she showed a very frightened expression and cried incessantly, obviously forced to photograph. The photographer constantly emitted a strange child-like laugh that had been processed with a voice change.

A week later, the remains of the girl in the videotape, a sophomore at Leonardo da Vinci Art School, were found and killed after being sexually assaulted. In the past six months, three female college students have been raped and killed in succession at the school. Another went missing last month and remains unaccounted for. There are also frequent incidents of theft of clothing and shoes in the school's girls' dormitory. People on campus are panicked, and girls are all in danger.

The police suspect that the provider of the tape is the perpetrator. However, the tape was placed directly in the office of the organizing committee of the film festival, no one knew who put it there, and there were no surveillance cameras outside the office, so there was no way to find it. There was no information about the person who took the film, and no fingerprints were extracted. After the police made a copy, they returned the tape to the organizing committee of the micro film festival.

The Leonardo da Vinci School of Art is a nationally renowned art school, and a succession of cases have had an extremely bad impact. In addition, the National College Student Short Film Festival is about to open, and it is urgent to solve the case.

The police suspected that the murderer was someone from inside the Leonardo da Vinci Art Academy, and sent people to take turns squatting and closely monitoring the women's dormitory complex, but they didn't expect a fire to break out tonight.

When Wei Chihong and Qiao Yan arrived at the Da Vinci Art Academy, the fire had already been extinguished by firefighters.

The fire was in a girls' dormitory building. The Leonardo da Vinci School of Art's women's dormitory complex is located on a hillside in the northwest corner of the campus, where all the female students live. It is surrounded by a wall, and access is through a large iron gate, and there is a communication room at the entrance.

The call that Wei Chihong received in the concert hall was from Lu Bin, who was already waiting in front of the girls' dormitory building where the fire broke out. The surroundings were still full of panicked girls, and many of them ran downstairs in their pajamas.

Lu Bin was dirty because he helped put out the fire, and his face was blackened. He saw Qiao Yan and Wei Chihong coming together, and stared at her in surprise. Qiao Yan didn't want to explain anything, and looked at the situation around herself.

"What's going on?" Yu Chihong asked.

Lu Bin reported that there was a container coffee shop next to the girls' dormitory complex, and he was squatting in the coffee shop tonight, and later heard someone shouting "on fire", so he rushed over to help. The fire started in an uninhabited dormitory on the first floor, and the room was very

It was about to be engulfed in flames, in the stage of fierce burning, and the entire floor was filled with thick smoke. The fire spread to the dormitory next to it, but fortunately no one was trapped, and after about 20 minutes of firefighting, the fire was successfully extinguished.

After hearing the general situation, Wei Chihong said: "You go and find out the cause of the fire, and you can go back if you figure it out." ”
