Zhang Yang walked out of the interrogation room and found that Wang Shuang was still sitting on the chair outside the interrogation room, stunned. Zhang Yang walked over and touched Wang Shuang's head and said, "Xiao Shuang, let's go home!" After that, he took Wang Shuang's hand and left the police station.

"Master, it seems that Zhang Yang still can't let go of Wang Shuang!" Xu Wei said.

"Well! Let's go to the conference room first, let's hold a temporary meeting." Wang Jianguo convened the members of the old case team, and six of them sat in the conference room. Wang Jianguo said: "After these two days of interrogation, we can say that we have accidentally gained a lot of clues, but it is not ruled out that some of these people are lying."

"Brother Wang, I have an idea, but it needs a specific review!" Liu Yi said.

"On the first day, we did not get any favorable clues on the teacher's interrogation, but we learned some clues from Chen Xiaoyan. The teacher is likely to be concealing what happened in the school at that time. I think Chen Xiaoyan knows something else, but she didn't say it clearly." When Liu Yi was alone with Chen Xiaoyan, he felt that she looked unstable when she mentioned Cong Zhijun.

"Indeed, but there is no evidence that Chen Xiaoyan and Cong Zhijun have any special relationship. We need to investigate other colleagues of Cong Zhijun. The information shows that the convenience store opened by Cong Zhijun in the school was opened with another teacher." After Wang Jianguo said that, he asked Zhang Jie to take out a dozen of information behind him.

"Master, why didn't you see these that day?" Xu Wei was a little surprised.

"I just sent it, everyone can take a look!" After Wang Jianguo said that, he took out one of the files and continued: "This file was obtained from the General Administration. It took a long time. There were some, but it was at the North District Branch." Wang Jianguo pointed the files with his hands.

"From the current information, Cong Zhijun is indeed a good man, but his potential has always been suppressed by his own reason." Liu Yi said.

"From the ratio of men and women in Mingguang Middle School, there are more girls." Zhang Jie said while reading the information.

"We have now figured out the question of how the murderer threw away the body, but I have another new question. The murderer has no scars on his body, nor has he been attacked. So how did he obediently let the murderer take him away?" Wang Jianguo asked.

"Group Wang, I checked the autopsy report of that year again. The autopsy report showed that the victim had no alcohol or other anesthetic substances in his body, and there were no internal and external injuries on his body. These points are very suspicious. How could a person faint so easily?" Wang Lan was thinking hard, and Liu Yi said: "Is it possible to be acupuncture?"

"Liu Yi, I'll see if you've watched too many martial arts movies. I'm giving you two palms to see if you have any reaction!" Xu Wei put on a pose of palms on the spot.

"Viagra, don't make trouble, I'm serious. Sister Lan, is there any possibility of traditional Chinese medicine?" Liu Yi looked at Wang Lan with his eyes.

"It's possible, what you said is not impossible, but I don't understand acupuncture very well. However, I have a senior brother who is a Chinese medicine doctor, so we can ask him." Wang Lan was about to take out his cell phone after saying that.

"The General Administration should have some information, so we will go over and take a look tomorrow." Wang Jianguo said.

"That's great. You must know more about the case so that the case will have a breakthrough. The rest can be monitored by a few insiders and see if they have concealed this matter." After Liu Yi finished speaking, he picked up the information on the table and started reading it. He felt that all this was like fate. When the case was discovered again, all the relevant personnel appeared in the police's sight.

"Zhang Jie is in charge of Li Hanmei and Fang Xiaoyun, Xu Wei is in charge of Wang Shuang and Zhang Yang, and Ma Boxing will then investigate the online information of Cong Zhijun's case. Liu Yi and Wang Lan will go to the General Administration with me tomorrow." Wang Jianguo glanced at his watch and it was already six:30 pm.

"Master, do you want to treat me?" Xu Wei said with a smile.

"Go to treat you? I'll give you a kick, and act quickly!" Wang Jianguo planned to sort out these old files again to see if he could find new clues from here. After Xu Wei and others left, Liu Yi asked: "Brother Wang, did this case ignore many clues back then?"

"It's not to be ignored. The hardware facilities were not complete at that time, and the Sky Eye Project had not been implemented yet. There were very few clues in our hands. I also spent a lot of effort to check them privately, but I got nothing. The confessions I received were basically the same, and there was no use value at all." Wang Jianguo said.

"Does Cong Zhijun have no relatives in City C?" Liu Yi asked.

"After investigation, Cong Zhijun had no relatives in City C. He was a province from another province who came to City A in 1994. I asked the school at that time. The answer given by the principal was that Cong Zhijun was originally a security guard of the school. Because the school was expanded once in 1996, it needed to add a convenience store on campus to facilitate students to buy some daily necessities and food. The school recommended it, and finally Cong Zhijun and another security guard took over the work of the convenience store."

"Another security guard?"

"Yes, there was another security guard named Guo Dongliang, who was 3 years younger than Cong Zhijun and from another province. Both of them were usually in school, but Guo Dongliang did not live in school, but rented a house outside the school and occasionally stayed in the teacher's dormitory for one night. This information was not in our hands, but I checked it privately and felt that there was no connection with Cong Zhijun's case." Wang Jianguo said while lit a cigarette.

"Have you investigated this person?"

"The day after Cong Zhijun's death, Guo Dongliang died unexpectedly at home because of drowning."

"Drowned?"

"Yes, after examining Guo Dongliang's body, the alcohol content in his blood exceeded the standard. He found that there were more than a dozen bottles of beer next to the bathtub. It was initially judged that Guo Dongliang was drinking too much and was drunk in the bathtub. Who entered the nasal cavity and then entered the lungs, which eventually led to death." Wang Jianguo sent a text message on his mobile phone and continued: "You can check the detailed information yourself later."

"Who called the police?" Liu Yi asked.

"It's Guo Dongliang's girlfriend. When his girlfriend discovered it, Guo Dongliang was already dead."

"Have you found anything on the scene?"

"I was not present at the time and there were no signs of crime at the scene. This was incredible, so I had to be sentenced to death unexpectedly." Wang Jianguo shook his head, and then he twisted the cigarette butt into the ashtray with force.

After looking through it for a while, Liu Yi suddenly found Guo Dongliang's old files. Liu Yi looked carefully. Guo Dongliang, male, 27 years old, a security guard at Mingguang Middle School, once worked as a security guard at Youlian Shopping Mall. He had no criminal record. Guo Dongliang's family is relatively well-off, and the money for opening a small shop was given by his father.

Liu Yixin thought that if you want to further understand Cong Zhijun, you still need to investigate Guo Dongliang's understanding. Guo Dongliang's girlfriend is Qin Meili, a cram school teacher near Mingguang Middle School. She still lives in City C.

"Brother Wang, we need to take some time to investigate Qin Meili tomorrow!" Liu Yi stood up and stretched his waist and said.

"Okay, I will ask Xiaoma to contact us. Let's go to the General Administration tomorrow." At this moment, Wang Jianguo received an email. After Wang Jianguo opened it, he found that it was sent by Principal Li. "At this time, the design sketch of the school's outdoor toilet?"

"Let me see!" Liu Yi came to the front and was surprised to find that the pit inside the toilet was not dug by the murderer for a long time, but the construction unit wanted to use this hole for water renovation before, but due to geological problems, it eventually failed.

"Brother Wang, the hole dug by the construction unit is not very big!" Liu Yi pointed to the 50 cm on the sketch and said. Wang Jianguo nodded, "The murderer didn't last long, it's almost ten cm wide." As soon as Wang Jianguo finished speaking, Zhang Jie called.

"Group Wang, I found that Fang Xiaoyun did not know the hotel, but went directly to another place."

"Another place?" Wang Jianguo was a little surprised.

"Group Wang, the place she went to is located in a community not far from the hotel. Through verification with the community property, we finally confirmed that the person she was looking for was Qin Meili!" Wang Jianguo was secretly happy.

"Xiao Zhang, you've done it well, let's go now!" Wang Jianguo said while putting on his clothes and signaled Liu Yi to prepare to set off. In less than twenty minutes, Wang Jianguo drove, the two arrived at the location Zhang Jie mentioned.

"Group Wang, you are too efficient!" Zhang Jie said with a smile.

"You are different! How long have you been going up?" Wang Jianguo lit another cigarette.

"It's been about an hour!" Zhang Jie looked at his phone.

"Through these investigations, we cannot rule out the suspicion of their confessions," said Liu Yi.

Wang Jianguo nodded, and the three of them went upstairs together. After the three of them entered the elevator, Zhang Jie pressed the elevator on the seventeenth floor. Liu Yi smiled and said, "Okay! It's getting more and more powerful!"

"This is all a trivial matter. If you can't do it well, why do you stay in the group in the future?" Zhang Jie said with a smile.

Not long after, the elevator stopped at the seventeenth floor. The three of them walked out of the elevator, Zhang Jie signaled to the left, Wang Jianguo walked up and knocked on the door twice, and someone immediately responded, "Who?"

After Wang Jianguo revealed his identity, the door opened, and it was Qin Meili who opened the door. Wang Jianguo and Xu Wei showed their ID, and Qin Meili nodded, "Then you go into the house and talk!"

After Wang Jianguo and the other two came in, Fang Xiaoyun was a little surprised, but then calmed down. Wang Jianguo asked, "Do you all know each other?"

"Yes, we are actually best friends!" Qin Meili said with a smile, holding Fang Xiaoyun's arm.

"Originally we wanted to ask you something about Guo Dongliang tomorrow, but it seems that we can only be today!" After Wang Jianguo finished speaking, he observed the surroundings. Qin Meili's house is about 140 square meters and has an attic.

"You are following me?" Fang Xiaoyun finally realized.

"I'm sorry, the case is quite complicated, and we have no choice but to do so. I hope you can actively cooperate!" Although Fang Xiaoyun was a little angry, in order to prove her innocence, she could only actively cooperate with the police's investigation.

Wang Jianguo first asked Qin Meili: "How long have you known Guo Dongliang?"

"It's been a year!" Qin Meili was trying hard to recall.

"You were the one who called the police at that time. Did Guo Dongliang have any enemies?" Wang Jianguo asked.

"You asked me back then! Guo Dongliang is an otaku. He doesn't go out much. Where does his enemies come from? Every day he lives at two o'clock, one line, school, school home!" Qin Meili actually feels that Guo Dongliang is a boring man.

"After Cong Zhijun's death, did Guo Dongliang say anything to you?" After Wang Jianguo asked, Qin Meili's face turned blue in an instant, and Liu Yi was secretly happy. He knew that Qin Meili must know something.

"I, I don't remember..." Qin Meili denied it.
