The camera is wobbly, and the person filming seems to be walking. He can even be heard breathing.

The camera is dark, the shooting time is night, and the time shown at the bottom of the screen is 11:55 p.m. Then, the camera pans upwards to see a building with five floors. The camera rises all the way to the top floor of the building and then begins to move from left to right, as if looking for something. Suddenly, the camera stops in one place. Then the person taking the shot began to adjust the focus, and at this point it was clear that there was a person sitting on the roof of the building.

The effect of the video is too poor, and only the figure on the roof of the building can be seen in the picture, and the silhouette seems to be a boy. Then the camera stops on the figure. After about two or three minutes, the figure stood up, and he stood quietly on the roof for a minute or so, and then fell straight down. At the same time, the recording stopped.

The lights turned on, and Guan Xin fixed the video he had just dialed for everyone at the moment when the figure on the roof of the building fell.

This is the email that was distributed to the mailbox of the special case team at 0:5 p.m. on September 22, and the Chongyu City Public Security Bureau also received this email. Public security officers in Chongqing City quickly found the place where the footage was taken, and they found the body of a male deceased man downstairs. ”

Qi Kai said: "This is not suicide!" ”

Guan Xin said: "Watching the video is indeed like suicide. But now there is a new situation. On September 24, at 0:05 last night, the special case team and the Chongyu City Public Security Bureau received another video, and the second deceased appeared. ”

Zhao Jiyong asked, "What's the situation?" ”

Guan Xin put the photos of the scene sent by Chongyu City on the screen. "The first deceased was named Xiao Jian, 20 years old. A junior student majoring in materials at Chengnan University. The second deceased, Chang Yuwen, 20 years old, was a junior majoring in materials at Chengnan University. In addition, the two of them are classmates in one class and one dormitory. ”

Ji Ziyue said: "Two boys in a dormitory committed suicide two days apart? ”

Guan Xin said: "Yes, so the Chongyu City Public Security Bureau felt that something was wrong, and our email box also received a suicide video, so they applied for this case to be investigated by us." I've checked the account that posted the video, but the other party's server is abroad, so there's no way to track it down. ”

Qi Kai frowned: "Is this a provocation?" ”

Guan Xin nodded: "It can be said that after the second video was sent to our mailbox, this video also appeared on the Internet, and now there is a lot of attention on the Internet about the suicide of students at Chengnan University." ”

Shen Zezhi: "So the above requires us to solve the case in the shortest possible time, whether they commit suicide or not, I must at least find the person who sent us an email." Let's get ready, and we'll leave in half an hour. ”

Chongqing is located in southwest China, the economic center of the upper reaches of the Yangtze River. Chengnan University is one of the best universities in Chongqing, which has been established for more than 100 years and is a century-old famous university.

At two o'clock in the afternoon, the special case team rushed to the Chongyu City Public Security Bureau. The person in charge of receiving them was Jiang Hao, a young man who had just graduated from the police academy, and everyone called him Xiao Jiang.

"What you asked for has been prepared, and we have said hello from the school. Although the school and the police have been trying to protect the scene, because of the video, the school has been spread one after another. Xiao Jiang said helplessly.

Shen Zezhi nodded and said, "Okay, thank you." ”

After Xiao Jiang left, Shen Zezhi began to assign tasks: "We have very little information in this case, and we have to find all the clues ourselves." In addition, since the case has been put on the Internet, many media have blocked the school gate. So everyone should pay attention to their wording when encountering the media. Guan Xin then looked for the person who uploaded the video on the Internet, Qi Kai and Teacher Zhao, and you went to talk to the family of the deceased. Yun Qing is in charge of the body of the deceased to see if he can find any clues. Ziyue and I were in a group, and we went to the school to have a look. ”

"Yes." Everyone left for the moment.

When Shen Zezhi and Noriko arrived at the school, the situation here was even worse than they imagined. There was a large circle of reporters at the school gate, and it seemed that they could not enter through the main entrance. Shen Zezhi parked the car outside the school gate, and then tried to find a way to find the others to go in.

At this time, someone reached out from behind and wanted to pat Shen Zezhi's shoulder, and Ji Ziyue saw it and hurriedly shook it to stop him: "Hey, don't ......"

It's a pity that Shen Zezhi's body reacted much faster than his words, and the person behind him had already been pressed to the ground by Shen Zezhi's twisted arm.

"Who are you?" Shen Zezhi asked.

The boy who was twisted his arm grinned and said, "Hey, don't do it, I'm a student at Chengnan University." ”

"What do you want to do?" Shen Zezhi twisted even harder.

"Ah, let go, let go, my arm is going to break." The boy screamed in pain.

Ji Ziyue hurriedly pulled Shen Zezhi's hand away from the boy's arm.

"What's the matter with you?" The boy stood up and rubbed his arm and complained.

At this time, Shen Zezhi and Ji Ziyue saw this boy clearly, he was about the same height as Ji Ziyue, wearing a plaid shirt and jeans, dressed as a college student.

"What's the matter with you? What do you want? Shen Zezhi asked in a bad tone.

The boy seemed to be frightened by his momentum, and he shrank back and asked, "Are you police?" ”

Kiko smiled and asked, "How do you know." ”

The boy pointed to the license plate of their car. The car they were driving was a black city SUV, and although it didn't have any public security signs, the license plate knew at a glance that it was a car from the public security system.

Ji Ziyue nodded: "Good observation, we are policemen." ”

The boy showed an inquiring expression: "You're here to investigate the suicide incident, right?" ”

Shen Zezhi frowned: "What 'suicide gate incident'?" ”

The boy seemed to be more jealous of him, and Kiko quickly explained: "It's just the name given to the student suicide incident of Chengnan University on the Internet." ”

The boy looked at the media reporters at the school gate and said, "I can take you into the campus from the side road and avoid them." The boy pointed to the reporters.

"But?" Shen Zezhi looked at him.

The boy's voice was a little quieter: "But you have to tell me the truth of the matter." ”

Shen Zezhi looked at him with his arms crossed, the boy's head was getting lower and lower, and finally he couldn't bear his momentum, and walked towards the small door with the two of them in despair.

The boy led them to the east side of the school, where there was a row of trees planted outside the school's courtyard wall, and the boy walked across the lawn to the middle of the two trees and beckoned to them, then bowed down and disappeared.

Shen Zezhi and Ji Ziyue glanced at each other and walked over, and found that it was also a school wall surrounded by a fence, but a few fences had been knocked off, just the size of an adult to enter and exit.

When Shen Zezhi and Noriko went in, they saw the boy who brought them in standing inside waiting for them.

"Thank you, what's your name?" Noriko thanked him.

The boy showed a shy smile: "My name is Feng Keli." ”

The boy was going to class and was leaving quickly.

Ji Ziyue looked at the place he had just entered and said with a smile: "It's really not easy to come in." ”

Shen Zezhi: "Let's go and see the scene." ”

The place where the two deceased jumped off the building was the library of Sungnam University, which was the building when Sungnam University was founded, and it is also the last old building that has been preserved to the present. They found the place where the deceased had fallen and set up a cordon around it, and there were also police officers at the scene. To Shen Zezhi's surprise, there were not many students here to watch. According to common sense, if someone jumps off the building at school, these students will be curious.

Shen Zezhi showed his ID to the police guarding the scene, and then walked in to check the scene.

There were still black blood stains on the ground, and white lines outlined the shape of the deceased falling to the ground. Kikoko looked up, and then at the location of the deceased's whereabouts.

Shen Zezhi: "Discovery? ”

Ji Ziyue said: "Judging from the video, the deceased stood on the roof of the building for a few minutes before falling from the top, so according to the parabolic motion formula, the distance they fell was within the normal range." It can be ruled out that someone pushed them down from behind. ”

Shen Zezhi: "Judging from the video, they were the only ones on the roof at that time, and no one else was found. ”

Ji Ziyue was puzzled: "If they really committed suicide, then the people who took this picture knew in advance that they were going to commit suicide here every time, or did they all happen to appear here?" ”

Shen Zezhi looked up at the roof: "What do you think?" ”

Kiko shook his head: "It can't be a coincidence. ”

"Let's go up and have a look." Shen Zezhi said as he walked out.

This 100-year-old library was designed and built by a famous architect in China. As soon as you enter the hall, there is a hall with busts of the world's literary heroes, and the height of the first floor is very high, and there are beautiful crystal lamps hanging from the ceiling. The first floor of the library is more like a banquet hall. There is a large spiral staircase in the middle of the hall, and the height of each floor is normal when coming from the second floor. The staircase is in the middle, and there are two iron fence-like gates at the entrance to each floor, and there are pictures of Chinese and foreign celebrities hanging on the wall next to the staircase. It looks like there's a strong academic smell.

Because two students committed suicide by jumping from the library, the library is now temporarily closed, and students are not allowed to borrow books. Shen Zezhi had already identified themselves when they entered. The librarian accompanied them in to have a look.

When a few people walked to the fourth floor, Shen Zezhi looked at the locks on the iron fences on both sides and asked, "Why is this floor locked?" ”

"That's it." The administrator was a little hesitant, she was a young female teacher, and she was a student who graduated from Chengnan University.

"We just want to get to the bottom of things as soon as possible. Now that the students are panicking, the sooner they find out the truth, the sooner the library can be restored. Shen Zezhi said.

The administrator hesitated for a moment and said, "I've only been working here for three months, and I heard about the fourth floor of the library when I was in school. Oh, by the way, I'm a bachelor's and master's degree in history at Chengnan University, so I know a little bit of rumors. ”

Kikoko nodded and motioned for her to continue.

"In my first year of college, I heard that the fourth floor of the library had been sealed, and it was said that a librarian committed suicide on the fourth floor, and since then there have been strange things happening there, and it seems that many students have seen it. The school had no choice but to seal the fourth floor. However, there were no books on the fourth floor before, and it didn't matter if it was sealed. The administrator said.
