Hang Jiabai and Xu Bo looked at each other, Xu Bo took out his mobile phone to call his colleagues in the same group, Hang Jiabai called Bai Fuan "Grandpa", and then asked permission to watch the surveillance. Although it was inappropriate, Bai Fuan was still very happy when Hang Jiabai called him "Grandpa", after all, he had some bad thoughts about the other's grandmother.
Hang Jiabai's request was reasonable, and the current school leaders were really at a loss. They didn't even consider Hang Jiabai and Xu Bo's request and directly agreed to it. They wanted to find Xu Simiao more than anyone else. They even hoped that Xu Simiao had gone out to play instead of missing.
Unfortunately, the hope was slim. At this time, Liu Shuqing called Xu Simiao's phone but it was turned off. This undoubtedly cast a shadow on everyone's heart.
Xu Bo stayed behind to survey the road from the dormitory building to the second canteen. The school leaders did not leave but watched from the side. Lin Shuyue, Liu Shuqing and Hang Jiabai followed Bai Fuan to the monitoring room to watch the surveillance.
Lin Shuyue asked to see the video from last week, when Liu Shuqing and Xu Simiao felt they were being followed.
The school's surveillance videos are stored for half a month before being cleared. When the security guard in charge of the surveillance heard Lin Shuyue's words, he glanced at Bai Fuan and Hang Jiabai again. Bai Fuan said, "Show them."
They first looked at the surveillance footage from the morning, just like the previous times Bai Fuan had looked at the surveillance footage. This time, there was still nothing unusual on the surveillance footage. The students on the surveillance footage had all been visited, and except for a few people who had an impression of Xu Simiao, the rest had not noticed Xu Simiao at all.
Lin Shuyue thought about the conversation with Xu Simiao last night and paid special attention to whether there was a cleaner. However, from 7:00 in the morning to 7:50 in the morning, there was no sign of a cleaner in the cameras in multiple locations.
Hang Jiabai absolutely did not believe that a person could disappear out of thin air. He told Lin Shuyue personally, "This kidnapper must be fully aware of all the surveillance equipment in the school. He must have a certain foundation in this area."
Lin Shuyue nodded: "That's right, if someone kidnapped Xu Simiao, then he must be very familiar with the school's terrain, surveillance locations, and coverage, since he could kidnap someone in such a short time."
There are many students in the school, and Yangcheng University attaches great importance to the safety of students, so there are many surveillance cameras installed in the school. It is obviously not something that can be done overnight to clearly know the blind spots of these surveillance cameras. This person must have certain computer knowledge and have the opportunity to come into contact with these things in daily work.
Upon hearing this, Bai Fuan glanced at the computer screen and said, "I'll call the school's electrician team." In the school, only the electrician team would frequently come into contact with monitoring equipment.
Yangcheng University has a special team of electricians responsible for circuit maintenance. After all, it is still 2004, and even in a big city like Yangcheng, there will still be occasional power outages. There are several thousand teachers, students and staff at Yangcheng University, and it is a school, so the power supply to the school must be guaranteed.
Hang Jiabai nodded: "Thank you, Grandpa Bai."
Bai Fuan went to make a phone call, and Lin Shuyue and Lin Shuyue asked the security guard in charge of the monitoring room to adjust the monitoring time to the time when Liu Shuqing and Lin Shuqing discovered that they were being followed.
Liu Shuqing still remembers the approximate time: "The school has a curfew, and we came out of the KTV at around nine o'clock. We took a taxi to the bus stop in front of the school and got off. I drank a little too much and felt carsick."
"We thought the school was only a few steps away, there were shops on both sides, and there were pedestrians on the roadside. We thought there was no danger, so we decided to walk back."
Lin Shuyue knew that Liu Shuqing suffered from motion sickness. Not long after they got in the car together yesterday, Liu Shuqing became unable to move. Her face was pale and she was sweating coldly. Although she tried to cheer herself up when she got off the car, she was still listless.
Lin Shuyue used to have a friend who would suffer from motion sickness more severely after drinking.
"So when did you feel someone was following you?"
Liu Shuqing said: "It's at the corner where the bus turns."
The Yangcheng University bus station and the entrance of Yangcheng University form a 90-degree vertical shape of a figure 7. Opposite the corner are rows of shops selling food, clothes, hairdressing and everything else. When they are open at nine or ten o'clock, the lights are on.
If there is a place where people can hide, it is only the distance between the buildings.
Liu Shuqing continued: "We all felt it, and then quickened our pace back then."
Unlike outside the school, the curfew is in place at 10 o'clock. After 9 o'clock, most of the students who go out have returned. There is still a certain distance from the school gate to the dormitory building. In this distance, even with street lights, it is still eerily quiet.
"When we walked near the lotus pond, we felt like someone was following us. We looked for a shadow and found one following us when we turned a corner. We turned around and saw no one. We looked on the ground and the shadow was gone. We ran away and told Professor Bai the next day that someone was following us."
After listening to Liu Shuqing's narration, Hang Jiabai went over personally and adjusted the surveillance to the time between 8 and 10 o'clock. He stared at the surveillance video with his starry eyes, not missing the slightest sign of something wrong.
Lin Shuyue's eyes were on the good and evil discrimination system. Since she entered the school, she had never seen anyone with a good and evil value of more than 20%.
Lin Shuyue's eyes also fell on the surveillance camera, which had already finished recording from 8 to 10 o'clock that night. Hang Jiabai asked Liu Shuqing about her subsequent movements and continued to check.
Liu Shuqing and Xu Simiao's daily life is very monotonous. They go from dormitory to classroom to library to cafeteria. They rarely even have time to go to the canteen. Their route is simple and their figures can be seen everywhere in the surveillance videos.
There were cleaners nearby several times when they were in the same frame.
This also confirms what Xu Simiao said to Lin Shuyue yesterday and the speculations of Lin Shuyue and Hang Jiabai.
Xu Bo came in at this time. He had already visited Liu Shuqing and Xu Simiao's roommates. Xu Simiao and Liu Shuqing were both very easy to get along with. In the three months since the start of school, they had never had any conflicts with their roommates. The relationship in their dormitory was rare and harmonious in the same floor.
Xu Bo immediately focused his investigation on Liu Shuqing, but after questioning many people, he found out that Liu Shuqing and Xu Simiao had a very good relationship and there was no conflict between them.
Xu Bo asked Lin Shuyue if she had found anything. Lin Shuyue shook her head and said, "We haven't finished watching the surveillance yet. Officer Xu, have you found anything?"
Xu Bo was about to speak when the school's electricians arrived. Two of the three were in their forties, wearing gray work clothes with the words "Yangchang University" printed on them and name tags on their chests. Lin Shuyue took a quick look and saw that their good and evil values were less than 20.
Principal Pei, the director of the Moral Education Department, and instructors Xu Simiao and Liu Shuqing also came.
Lin Shuyue briefly explained it to Xu Bo, and Xu Bo knew it. He took out a notebook and a pen and asked the three people.
"Luo Mingda, right? Where were you and what were you doing between seven and eight in the morning?"
Luo Mingda is the leader of the electrician team. He said calmly, "The school checks the wires and switches of the computer room and teaching building once a week. At that time in the morning, we happened to check the library. Teacher Zeng, the administrator of the library, can testify for us."
The electrician team only had three people, and when they checked this route, they went together because it was more efficient. They not only had Teacher Zeng to testify, but also many students who got up early to study in the library to testify that they did not have any time to commit the crime. They did not even leave the library until the school organized faculty and staff to look for Xu Simiao.
Xu Bo took note and continued to ask: "Among the three of you, do any of you have any basic knowledge of computers?"
The two older ones in the electrician group couldn't help but look at the younger one, whose name tag read Zhao Wu. Being watched by so many people, including school leaders and police, he became nervous and his face turned red.
He stammered, "I don't have any basic knowledge either. My son learned some computer knowledge in school and taught me when he came back. I just search for movies online. I can't even type well."
Xu Bo wrote this down: "Is it convenient for me to go to your house and check your computer?"
Zhao Wu nodded his head: "Sure, sure."
•••••
When Xu Bo was asking the electrician team, Hang Jiabai had already finished watching the surveillance records of the past few days. He accurately reported the time and location of several surveillance shots. As he reported, one picture after another was frozen, and people in orange work clothes appeared on the big screen.
But once the big picture was fixed, Lin Shuyue knew that these cleaners would not be suspects, because their body shapes were very different. Unless they were a gang.
When the person from the logistics department saw this, without Hang Jiabai saying anything, he picked up his phone and called the cleaning team. After a while, the cleaning team arrived.
They are all very old, two boys and three girls, and they all knew about the big thing that happened in the school. When they were called in, they were particularly nervous.
Lin Shuyue's good and evil radar scanned the area and found that the good and evil value was still less than 20, which did not meet the standard for committing a crime.
Xu Bo compared them with the people on surveillance video one by one, and then asked about their work schedules and activity range for that day.
Obviously, these cleaners were not voyeurs, and they had no time to commit crimes between 7 and 8 in the morning. The investigation was at a stalemate. The cleaning team left quickly, and Lin Shuyue and others also left the monitoring room.
As soon as they walked outside, two couples came in. The couple walking in front had tears on their faces, and the couple walking behind also looked worried. They were Xu Simiao's parents and Liu Shuqing's parents.
Liu Shuqing, who had stopped crying, started crying again at this time. She stood out from the crowd and shouted a series of names: Dad Xu, Mom Xu, Dad and Mom.
Just from the way Liu Shuqing addressed him, one can tell what the relationship between the two families is.
Mother Xu and Liu Shuqing's mother took Liu Shuqing's hands and began to inquire about the situation, while father Xu and Liu Shuqing's father went forward to negotiate with the school leaders.
Lin Shuyue and others were listening on the side, and they soon learned about the situation of the two families.
When the wave of layoffs hit, father Xu became a laid-off worker. Instead of becoming depressed, they started setting up a small stall to sell vegetables from their hometown. He now runs a wholesale market, and 50% of the vegetables sold in their store are sold in his market.
Liu Shuqing's parents are both employees of the machinery factory. Father Liu is a technician. After the state-owned factory closed down, he opened an electrical appliance repair shop. Now he has opened his own repair shop and has received continuous orders. The relationship between the two families has always been good, the family is well-off, and the parent-child relationship is also good.
At this point, suspicion on Liu Shuqing has been ruled out.
The arrival of Xu's father and mother attracted many students to watch. Lin Shuyue's radar swept over the students, and then she fixed her eyes and said to Hang Jiabai beside her: "Ah Bai, at the six o'clock direction, chase."
Hang Jiabai trusted Lin Shuyue 100%. As soon as Lin Shuyue finished speaking, Hang Jiabai shot out like an arrow. Carrying her bag, she also followed.
