After waiting for less than half an hour, Gu Song received feedback from Xia Shi. After Jiang Shun's identification, the middle-aged man in the photo was indeed the obscene uncle who took the initiative to talk to him and flirt with him in the bar last month.

The man who once appeared in the Bar of the Valley of the Stars also appeared by Brother Yu's side, which has to make people think about his identity.

According to previous speculation, Mr. Z's role in the criminal gang should be "middleman". His task was to contact the local connector or buyer to sell the "goods" provided by his accomplices. If that old Zhao is the legendary Mr. Z, then he should have very important information in his hands. As long as his identity can be confirmed, the police will be one step closer to the core of the criminal organization.

It's a pity that Xiao Hai doesn't know much about Lao Zhao's situation. Counting the meeting in KTV last night, they have only met twice in total, and there is no substantive communication at all. Xiao Hai only knew that Lao Zhao was a friend of Brother Yu, as for whether he had anything to do with the criminal gang and whether he was the "delivery person" the police were looking for, this matter had to find a way to confirm, and it would not work just by guessing.

In the following days, Gu Song's undercover life was a little boring. In his spare time, he couldn't help but think of two unsolved cases that had happened before.

Through Xia Shi, Gu Song learned about the latest progress of the two cases. Among them, the "4.7 Homicide Case" taken over by Zhao Xiaolin and Meng Yu has completely reached a deadlock. After all the interviews failed, they released some information and tried to collect clues about the "Night Killer" on the Internet.

To their great disappointment, however, the people of R City seem to be more willing to side with the killers than with the police. Because they hate the sinful deeds of human traffickers, they see the actions of their killers as justice. So even if they have clues that can help the police solve the case, they are unwilling to cooperate with the police.

Zhao Xiaolin was worried about this case all day long, didn't think about tea and dinner, and looked forward to Gu Song and Xia Shi going back to help as soon as possible. Meng Yu's mentality is better than Zhao Xiaolin's, because he has little confidence in solving the case from the beginning.

The "4.13 Campus Homicide Case" is related to Mu Zi and Jiang Xiaoyan, whose whereabouts are unknown, so Xia Shi has been very concerned about the progress of the case. Although he was not involved in the investigation of the case, the police officer in charge of the case gave him the green light. As long as he asks, the other party will reveal the latest investigation results to him.

According to Gu Song and Xia Shi's suggestion, the police made a detailed list of all the senior high school students who were not in the classroom at the time of the crime. There are a total of 23 students in the list, excluding those who have alibi certificates and those who do not meet the criminal profile, and there are still 6 students left. Of the six students, only two had a life intersection with Mu Zi. One of them is Han Jia in the fourth class of high school, and the other is Mu Zi's classmate, the study committee member of the second class of high school, Jin Zhe.

Han Jia is a well-known bad boy in the school, who often bullies Mu Zi and makes some vulgar and bad jokes with Mu Zi. At the time of the incident, Han Jia said that he was secretly smoking in the men's toilet on the third floor, but no one could confirm whether his words were true. However, Han Jia did not have any friendship with Jiang Xiaoyan, and he would not know that Jiang Xiaoyan's disappearance was related to Mu Zi, so it is unlikely that he hid an anonymous letter and framed Mu Zi.

And at the end of the investigation, Jin Zhe, the only one left in the list of suspects, is relatively more suspicious of his crimes. At the time of the incident, Jin Zhe, who has always been diligent and hardworking, did not study in the classroom. When the police asked him where he was, he replied that he was dizzy and ran to the atrium on the second floor to change his mood.

After an in-depth investigation, Jin Zhe and Jiang Xiaoyan used to be junior high school classmates, in different classes in the same school, but according to former classmates, Jin Zhe seems to have always liked Jiang Xiaoyan. If Jiang Xiaoyan disappeared because of Mu Zi, then Jin Zhe has reason to hold a grudge against Mu Zi. That is, his motive for committing the crime is established.

Not only that, Jin Zhe was also disgusted by Ling Xiang, who spoke harshly and harshly, because of his poor family conditions and ugly dress. So he killed Ling Xiang and blamed Mu Zi for the crime, which can be described as killing two birds with one stone.

Kim Chul is now in the same class as Mu Zi, and it is easy for him to hide the anonymous letter in Mu Zi's revision materials without being discovered by other classmates. As a classmate at Ling Xiang's back table, it is not surprising that Jin Zhe understands that Ling Xiang has the habit of sneaking to the rooftop to smoke during self-study at night.

So to sum up, Kim Chol's suspicion of committing the crime is the greatest. But the problem is that when he was questioned by the police, he made it clear that he didn't know that Jiang Xiaoyan had an accident, let alone admitted that he had hidden anonymous letters in Muzi's study materials, so murder, framing, and revenge had nothing to do with him.

So far, the police have not found evidence of Kim Chol's crime, and the case has reached an impasse to some extent. Mu Zi's suspicion of committing the crime has not been ruled out, but she has now dared to face the criticism of her classmates and put all her energy on the upcoming college entrance examination task.

On the evening of April 21, 2016, Gu Song met Brother Yu for the second time. This time, Xiaohai invited Brother Yu to drink, which was regarded as making up for Brother Yu's birthday a few days ago.

The two sides made an appointment to meet at a seafood stall with a very good reputation. Brother Yu brought two brothers over, but Lao Zhao was not among them, which couldn't help but make Gu Song feel a little disappointed.

Xiaohai seems to be familiar with each other's relationship, and as soon as they meet, they hand each other cigarettes and make jokes about each other unscrupulously. After the two sides introduced each other, Brother Yu took the menu and said with a smile: "Ah Hai, it's rare that your iron rooster is so generous today, brothers can't waste your kindness." ”

Xiao Hai smiled bitterly, pointed to the lobster on the menu for 399 yuan a catty, and said half-jokingly: "Brother Yu, drink as much as you want today, forget it." If you really want to eat lobster, you can only sell me. ”

Brother Yu looked at him and smiled, teasing him and said, "Yo, with your appearance, if you sell it, you can only change the lobster head at most." After speaking, he looked at Gu Song, who was sitting beside Xiao Hai, again, "If we sell this brother of yours to a rich woman, we will not only be able to eat lobster, but we may also be able to make a lot of money." ”

Hearing this, several people burst into laughter, especially Brother Yu's two friends, who had a hint of obscenity in their laughter, and even Xiaohai echoed Brother Yu and said that it was a good idea.

Gu Song knew that they were joking with themselves, but he still scolded and said, "Damn, you guys are so inhuman, why don't you even let go of your own people?" ”
