The new batch of college graduates will officially enter the society in two months, and they will go their separate ways. Most of the new graduates have already found a job or started an internship at this time, or are on the road to find a job, or take advantage of the last carefree time in the ivory tower to go on a commemorative graduation trip. In short, this group of people is basically no longer visible in the school.

However, a small number of graduates still stay in the school, at least every night in the student dormitory.

On this day, a girl came to Liu Mengwei and saw that the teacher didn't seem to have much impression of her, so she introduced herself briefly. The girl's name is Luo Wan, a graduate of medicine this year, and she once took Liu Mengwei's elective class.

"My roommate may be missing."

Although Liu Mengwei was puzzled, she still listened patiently to her story.

The girl, Luo Wan, had a roommate named Yang Ximin, who had not returned to the dormitory about ten days ago.

After negating all Liu Mengwei's speculations about her whereabouts, Luo Wan said categorically: "Teacher, I'm pretty sure that she must be in danger now, either being deceived somewhere, or being controlled!" ”

Then she said the basis for her judgment. It turned out that Yang Ximin's phone was not always unreachable, Luo Wan had dialed it several times, but Yang Ximin's attitude on the phone was very abnormal, constantly shouting and cursing, and speaking viciously to each other.

"Teacher, as long as you inquire a little, you should be able to know how gentle Xiao Min usually is, how kind she is to others, she will never say such a thing, she is asking me for help! How desperate she would have been if I had turned a blind eye! The girl said sincerely, but Liu Mengwei was still puzzled: "Since you have suspicions, shouldn't you go to the police?" ”

"I reported it, but the police refused to believe me after hearing Xiaomin shouting at me on the phone to tell me not to harass her."

"And do you have any other evidence?" Liu Mengwei also felt a little embarrassed, although Luo Wan said a lot, but most of them were her feelings and conjectures, and there was no substantive evidence, and even the phone of this female student named Yang Ximin could occasionally get through, it could not be regarded as a state of disconnection, no wonder no one believed her.

Seeing that Liu Mengwei was also suspicious of her statement, Luo Wan seemed to have made a lot of determination, and said hesitantly: "Teacher, do you know Xiaolou?" ”

Xiaolou does not refer to a certain person, but to a telegram group. The so-called telegram group is a kind of chat room in cross-platform instant messaging software, because the server of this communication software is set up overseas, ordinary networking is unable to log in to these websites, and it is necessary to build a ladder over a wall to get through, so it is difficult for domestic laws and regulations to supervise and control it, so many black industry chains are growing and developing unscrupulously in this place where the sun does not shine.

And this chat group named "Xiaolou" is ostensibly used to make friends and make dinners, and of course ordinary friends don't need to do this, that is to say, they have another shady purpose.

According to Luo Wan, the girl who had been to that dinner party came back every time she carried a beautiful gift bag, sometimes high-end jewelry, sometimes a luxury brand bag. This kind of not only can eat the delicacies of the mountains and seas, but also get a good opportunity to get thousands of yuan gifts, of course, no one can be exclusive, many girls go once or twice and are squeezed by the newcomers, after all, who doesn't like freshness, let alone those well-informed big people.

How can such a good thing be done to stay and enjoy what is happening without giving anything else? In fact, some people originally went to climb relationships and open up social circles, and they didn't care about these three melons and two dates.

"Xiao Min was there last week, I saw it." Luo Wan said: "I worked part-time in a 24-hour convenience store on Xincheng Pedestrian Street, and I was on the night shift that day, and when I was sorting out goods at the door, I saw Xiao Min walking in front of me, and she and a middle-aged woman entered a bar called 'Yulouchun' opposite. Since that night, Min hasn't been back to the dormitory. Later, in order to find out her whereabouts, I also added that group, and then I realized that the bar was their contact location. ”

Luo Wan suspects that Yang Ximin's disappearance is related to the people in Yulouchun's bar.

"But what can I do?" Liu Mengwei still looked helpless.

"I'm sorry, teacher, I really can't help it, I don't know who I can talk to about it, so I want to talk to the teacher of the Department of Psychology, hoping to get some advice." Luo Wan's face was full of sadness, and she looked at Liu Mengwei as if asking for help: "Moreover, I heard that the teacher knows the police and has handled cases with them." ”

You're well-informed, Liu Mengwei thought, it's not a good thing to feel too familiar with a student for the first time, and does anyone remember that she is a teacher who teaches criminal psychology and neurocognitive science, not a psychological counselor who listens to other people's troubles. She finally understood the helplessness of those students majoring in software and computer science when they were always caught fixing computers.

Since this is a long-standing secret business, it naturally has its rules of survival, why would an ordinary schoolgirl break the rules? Could it be that she offended the reverse scale first?

"Their people have already asked me to meet." Luo Wan said again, Liu Mengwei was shocked, only to hear her say again: "But...... I'm so scared now, I'm ...... I don't dare to go ......."

It turned out that Luo Wan had already connected with the people in the bar and planned to sneak in to find out the news. Yes, not everyone can have this kind of opportunity, and if you want to buy a ticket to see the life of high-class people, you have to check your qualifications first.

Liu Mengwei came to this place in place of Luo Wan and met the woman named Milan.

Milan was so happy with her that he even wanted to make a big deal for her. Liu Mengwei talked nonsense with her for more than an hour until Wen Qiao appeared.

"To be honest, I don't think that the disappearance of that schoolgirl has anything to do with the kind of business that this place is doing in secret, especially the owner of that shop, it seems that he should be just a broker, there is no need to ask for trouble and make things bigger."

Wen Qiao hadn't told her about the suspicions of the police, and she was still hesitating to say it, Liu Mengwei had already asked, "What case are you here to investigate today?" ”

Wen Qiao didn't answer directly, but asked, "Can you be sure that the woman named Milan is the boss here?" ”

Liu Meng was slightly stunned, obviously she hadn't thought about this problem, she lowered her eyes, fell into thought, and said faintly after a while: "According to the communication and observation I just had with her, this person should not be married, but there should be a lover with a stable relationship, and of course it is not excluded that there are several lovers with unstable relationships." She has a strong personality and doesn't read much, so she should have come out to break into society at a very young age. There is a high probability that it is not the only daughter in the family, and it is likely to be the role of the eldest or second child. Unless there is a stiff quarrel with the family, the eldest sister in the family is developed, and it is unlikely that she will not bring her siblings with her. ”

"According to my understanding, this place of Yulouchun is like a post station where people come and go, exchanging information, and this person in Milan is Bai Xiaosheng of the rivers and lakes. She meets all sorts of people, and when she finds that there are people in her network whose needs match each other, she connects them with each other. ”

"The six-dimensional space theory means that there will be no more than six people between you and any stranger, and you can contact any stranger through the network of people between six people at most. But if you get to know Milan, you don't need any other nodes and can go straight to your destination. ”

"So, even if this bar is not under her full control, I believe that the role she plays in it will definitely not be small."

After listening to Liu Mengwei's analysis, Wen Qiao asked again: "What does she want you to do?" ”

Liu Mengwei seemed to suddenly remember this incident, her face suddenly pulled down, and she said angrily: "They want me to get close to a person named He Rulin, this person seems to be a professor at a university, and he is going to come to Yunhe City for an exchange visit in two days, I don't know if it is the intention of the organizer or his own meaning, I want to find an escort during this time." Liu Mengwei said vaguely, but the meaning was self-evident.

"You just promised her."

Liu Meng glanced at him slightly: "That's not to relieve you from the siege?" You haven't even said why you're there! ”

Wen Qiao finally told her about the suspicions of the police, and Liu Meng's eyes widened, obviously surprised: "This place is still suspected of drug trafficking?" ”

"No definite evidence has been found yet, and it is still in the investigation stage."

Liu Mengwei suddenly felt a little afraid: "If this place is really involved in drugs, then things are not so simple." ”

Wen Qiao snorted lightly: "Do you know that you are scared now?" Seeing that Liu Mengwei bit his lip and didn't speak, he comforted: "However, after what happened just now, I think this group of people should not have the courage to do the drug business." Otherwise, if I suddenly appeared on the third floor with such a fresh face, they would be able to make it easy for me to get through the barrier, which basically shows that the place is not afraid of outsiders. These people are naturally not innocent, but the degree of blackness does not seem to be so deep. ”

After his reminder, Liu Mengwei also came to her senses and felt that what he said was reasonable. "Okay, what I'm going to check and what you're going to check seems to be fruitless.".

"No, what I'm trying to find out may not be that easy, but it's not that complicated if you want to find out if the schoolgirl is really missing." Wen Qiao said.

Liu Mengwei's eyes lit up.
