"Testify to each other? I think we're going to go down to this old friend's dormitory for a walk. During the conversation, Jiang Dong took Li Yifan to greet Li Yi and went to Li Yi's dormitory.

Li Yi is a second-year student in the Department of Computer Science and Technology of the University of Science and Technology, and he saw a lot of trophies and generals in Li Yi's dormitory, and saw that no one had all kinds of pet supplies on the table, and there was a glass fiber reinforced plastic on his bookcase, and there was a black spider lying directly in it. Jiang Dong was chatting with a few of them and learned that Li Yi and the rest of the people in this dormitory liked to have pets, and some people in the dormitory objected, so they tried to transfer a few people with similar interests to the rest of the dormitory, this process was quite difficult, their school did not let students live outside, and they were directly expelled once found.

A student in the dormitory even showed Jiang Dong his reptile pets in his wardrobe, and after chatting about how several of their pets were persecuted by Cui Liang, Jiang Dong and Li Yifan left the dormitory.

"Let's go and ask the teacher what the awards are." In fact, Jiang Dong began to suspect Li Yi as soon as he entered the dormitory, according to his understanding, Li Yi was a graduate student of the university who was directly admitted to the university, which means that he may have been abused and killed by Cui Liang during his undergraduate years.

"You said Li Yi, that's a genius in our school, those awards are all obtained by some technology designed by him, what kind of security system and encryption system and some security and cracking technology. His thesis ...... followed by a bunch of compliments, and Jiang Dongzhi remembered what the teacher said about the awards.

"Han Shuo, I have someone here who wants you to talk to him and learn about computer technology." After Jiang Dong stood downstairs and finished talking to Han Shuo, he asked a policeman next to him to take Li Yi back to the police station first.

"I heard Wu Shuai say that he is also suspected?" Li Yifan looked at Jiang Dong's logic of arresting people, and estimated that as long as one side occupied the side, he couldn't run away, and Wu Shuai has been very strange recently, always running out. "I remember that after seeing Xu Juan's death that day, I woke up and saw Wu Shuai listening to music in bed, so I can ask for suspicion."

"But he went out before, we saw Wu Shuai's figure in front of the store Xu Juan passed before his death, and I thought it was a passerby when we were investigating, but later found that Wu Shuai was indeed suspicious during the investigation, so we compared it and found that it was him. And the accomplice doesn't have to stay at the scene, maybe help the contact person to catch mice in the school cafeteria! Jiang Dong said slowly with a smile on his face, there was a rat trapping team near their school, and they caught mice in this area, and later when they were dealing with it, someone said that they had a pet python and took the mice in the car away.

Li Yifan stood there and didn't know what to say, Wu Shuai's strangeness was indeed from the fact that after the two people who abused and killed animals were exposed, he was making such a big fuss and was so cruel, it was not something that could be done by one person, and it was very likely that many people assisted this 'kobold hero'.

At four o'clock in the afternoon, the schools on both sides basically closed the team, and the school's side, including Li Yi and Wu Shuai, was finally narrowed down to three people, and there were still doubts about the people, while the school left one person to investigate the confessions and time evidence of these eight people, and the other three people were taken to the police station, and Li Yifan and Zhang Rui went back to the dormitory.

"Did this kid say anything?" Jiang Dong pointed to Li Yi, who was bowing his head in the detention center, and asked Han Shuo next to him.

"Captain, are you sure it's him? It's not like we've had a pretend suicide case before! Han Shuo didn't ask for any useful news, and the chat with Li Yi in the morning was almost just about computer technology, and the two of them only now had a feeling of hating each other.

"Captain, after careful screening, this Cui Liang is indeed another distant cousin, but the two have not been in touch since they became adults." Lao Xu told Jiang Dong the information he had found, because he had been investigating the relationship between friends and relatives in the past few years, things like this that he hadn't seen in seven or eight years were directly ignored.

"Well, who is it?" Jiang Dong took the information.

"It's called Cai Xiyan, it seems that there is still a little fame in our city, and almost all the little girls in the technical department know it." When Lao Xu mentioned Cai Xiyan's name, several people in the detention center couldn't help but raise their heads and look at this side, and immediately went down again.

"Follow the check, don't catch it and ask." Jiang Dong noticed the movements of the people not far away, especially Li Yi and Wu Shuai, the fluttering eyes, they may not know that this scene just now was filmed by the overhead monitor, and the computer in front of Jiang Dong showed this.

"Check the mobile phone records of these people, and see if you have contacted this Cai Xiyan, especially Li Yi's, his password cracking, I think you can ask, maybe it can be used on the mobile phone at Xu Juan's scene." After leaving this sentence, Jiang Dong came out of the interrogation room, he frowned and looked at the information of Cai Xiyan in his hand, the name of a hospital on it was very familiar, he closed the information and took people to Cai Xiyan's house together, and when he went out, he happened to see Li Yifan and Zhang Rui and a little fat man in their dormitory standing at the door of the Public Security Bureau with two bags of things.

"Cousin, can we go in and send something to Wu Shuai, no, he hasn't eaten since yesterday afternoon, and it's already the beginning of autumn." Zhang Rui looked at Jiang Dong standing on the platform, and deliberately said that brother loudly, Li Yifan has been in the detention center, and knows that the treatment of everyone in the detention center to help you speak is different from that of no one to help you speak, Wu Shuai's family is not here, and no one can only get a few of them up.

"Okay, okay, you take it in, and say how pitiful our guards are." Jiang Dong couldn't stand them like this, so he waved his hand and let them go in quickly. "By the way, Li Yifan, you stay, I have something to ask you." Just now, Jiang Dong clearly saw the name of Bairan Psychological Hospital on the information.

"What's there in Team Jiang?" Li Yifan whispered to Jiang Dong, who pulled him aside and was mysterious.

"Have you ever seen a person named Cai Xiyan in Bai Ran's clinic?" Jiang Dong asked Li Yifan.

"I've seen it." This name Li Yifan is familiar with it, but he appeared in a strange way both times.

"Did you notice anything strange about him?" Jiang Dong asked tentatively.

"I can't tell......" Li Yifan recalled. Have you seen the video uploaded on the Internet before, the man who looks like a dog? ”

"No, to the point!" Jiang Dong asked anxiously.

"It's that I saw that he was obviously a big man, but he was chained like a dog, and he also made a very low dog bark......" Saying this, Li Yifan seemed to suddenly realize that his eyes widened and his mouth grew.
