At three o'clock in the morning, the September sky was beginning to cool, with a breeze blowing from time to time, and the school was silent, except for the rustle of leaves. Shen Mingyu woke up suddenly, he came to the corridor and looked out the window, lit a cigarette, he is now used to taking one when he is thinking about things, this will make him more thoughtful. But there is still no clue about this matter. Now there are too few clues, and it is not enough to startle the snake. Suddenly, he heard footsteps behind him, he instinctively turned back, but saw a familiar figure, and before he could speak, the other party spoke first: "Can't you sleep too?" This figure is Wen Qiao, she also walked to the window and looked out of the window with Shen Mingyu. Yes, the quality of sleep is not very good, I always wake up in the middle of the night, I can't sleep, I just come out to blow the wind. "How did you feel about spending the night in the girls' dormitory for the first time?" Wen Qiao asked. "At first, I thought it was special, but now it doesn't feel like much, it's all the same." The two chatted with each other, Shen Mingyu has rarely been chatting with him since he separated from his girlfriend, and now that a girl suddenly appeared, he was a little overwhelmed. I don't know how long it has passed, the sky is slightly brighter, Wen Qiao said: "Go back and lie down for a while, otherwise it will be dawn, and you will be sleepy during the day, which will affect your state." Shen Mingyu nodded, returned to the abandoned dormitory, and fell asleep.

In the early morning, the sun shone on the corridor, and the students woke up one after another, because today is the weekend, so many students are still immersed in sweet dreams. After Shen Mingyu got up and washed, he subconsciously looked at the 601 dormitory and found that the door was still closed. "It seems that everyone is sleeping lazily" A familiar voice fell, and Wen Qiao was greeting him with a smile. Shen Mingyu also smiled when he saw that it was Wen Qiao. "yes, it's the weekend, I don't know what their plans are, and I haven't collected any clues for a day." "I know them very well, Ning Lin should be the earliest, Liu Qiwei broadcasts live every afternoon and evening, usually other people will go out in the afternoon, let her be in the dormitory by herself, they have a lot of opinions, but it's not easy to say anything, she should get up in the afternoon, other people's words are not necessarily, and many students on our floor are locals, usually go home on Friday night, and there are many students who love to go out on weekends, in fact, there are quite few people in the dormitory, like our dormitory is now only me and another person, However, everyone in the 601 dormitory is out of town, except for Liu Qiwei, the number of times others go out is not very much. "Do you love live broadcasting......" Shen Mingyu helped his chin. All morning, Shen Mingyu tensed his nerves, observing the situation around the dormitory, but found nothing. At noon, Wen Qiao came to Shen Mingyu to eat together, because Shen Mingyu did not have a meal card and preferred to eat snail noodles, so he could only swipe Wen Qiao's card. "I'm going to trouble you again...... My hometown is where snail noodles are produced, and I don't like to eat anything else here, hahaha. Shen Mingyu said embarrassedly. It's okay, I also love snail noodles, I haven't been to you yet, I must eat a bowl of authentic food when I have the chance. The two came to the cafeteria together, because they had already greeted the dormitory manager, and Building 7 knew that someone was coming to repair the ceiling, so Shen Mingyu changed into his own clothes, and he didn't have to carry a tool bag all the time, but he still couldn't leave his work permit. After eating, because there was nothing special, Wen Qiao took Shen Mingyu to help move the courier, because the express station in the school could not store large items, so he could only go to the courier station outside the school to pick it up.

At one o'clock in the afternoon, the people in the 601 dormitory went out one after another, Liu Qiwei put on makeup and prepared to start the broadcast after washing, and her goal today is to receive more gifts from her eldest brother. "Good afternoon, family, I'm here on time, hey, welcome big brother, yo, it's not my brother Zhang, thanksgiving, thanksgiving, thank you Brother Zhong for the carnival! My sister is on her knees! Add the anchor's WeChat needs to brush 5000 gifts......" Liu Qiwei in the lens is glamorous, as an Internet celebrity with tens of thousands of fans, many "big brothers" are crazy to deduct the barrage and let him perform his talents. Behind the camera, in the empty dormitory, a girl is dancing and performing, just to win the favor of the big brothers. Liu Qiwei is not like this, she was born in a poor family, her father was in poor health for a long time and needed surgery, she helped the family to shoulder the burden very early, from elementary school to high school, her grades were very good, and she usually went to work part-time. When she was in college, she came to the big city A from a small county, the prosperity of the big city made her feel as if she had stepped into a new world, at the beginning she studied hard, won a scholarship, and saved money just to save more money to send home to her parents, but one day her father's condition suddenly worsened, and more treatment costs were needed, Liu Qiwei could only work part-time in her spare time, but it was still far from enough. One day in her sophomore year, because she couldn't maintain the high cost of surgery and medical treatment, her father told her and her mother not to spend money for themselves, it was a bottomless pit, and to keep the money for a good life. Just three days later, the father left, leaving behind the lonely mother and daughter. That night, Liu Qiwei dried her tears, one hating herself for not being able to save her father, but hating why she had no money. Since then, Liu Qiwei has the idea of "as long as I have money, I can do anything", she began to look for a way to make money, and a friend introduced her to the live broadcast industry, which is in the limelight, saying that this money comes quickly. Liu Qiwei did not hesitate to start the live broadcast, because of her good face, she quickly attracted a lot of fans, and gradually, her clothes, bags, and cosmetics gradually increased, and she wore famous brands. The more the eldest brother's demands are excessive, the more money she can get, eat and meet, accompany shopping and travel, and even spend a good night with the eldest brother. She started to rub the edges, because it would get more traffic and attract more people, and she was gone on this road forever, going farther and farther.

Liu Qiwei's live broadcast was watched by 20,000 people, Liu Qiwei looked at the dense barrage, very happy, and made various actions to express her gratitude to fans. At this moment, a man in a hooded sweatshirt, wearing a mask and sunglasses, is walking into the 601 dormitory. Liu Qiwei didn't notice that someone came in, and she was still working the live broadcast, at this time, the person quietly walked behind her, and the barrage was talking about who the person behind was, asking the anchor to look back, but Liu Qiwei thought that the barrage was just joking, and did not look back, but the barrage did not mean to stop, but more and more, at this time she felt that something was wrong, and when she wanted to turn back, she found that her neck was scratched by something and she lost consciousness. At this time, those watching the live broadcast found out that the person in the hooded sweatshirt used a bright knife to cut Liu Qiwei's throat. Then, the man turned off the live broadcast, and next to Liu Qiwei's body, he put down a note that read: "The first drop of blood, revenge." He walked out of dormitory 601.

Shen Mingyu was carrying the courier and Wen Qiao back to school together, suddenly the mobile phone rang, he picked up the mobile phone and saw that it was Han Sicheng's call, he didn't dare to slack off, pressed the answer button, and Han Sicheng's hurried voice came from the other end of the phone, "Xiao Shen!" Where are you? Someone in dormitory 601 was killed! Hurry up and take a look, I'll be there shortly, I'll send you a message for the details! "Shen Mingyu was like a bolt from the blue after hearing the news, he just left for a short while, and there was actually a case, could the deceased be Ning Lin? He and Wen Qiao explained the situation, and the two ran to Building No. 7 together, on the way Shen Mingyu checked the information, Han Sicheng said: The deceased is Liu Qiwei from the 601 dormitory, she was cut behind her back during the live broadcast, tens of thousands of people were watching the live broadcast at that time, and the police calls were blown up, and the specific situation will wait for the forensic and forensic personnel to come over, you quickly contact Xiao Li Xiao Liu to block the scene. Shen Mingyu called Xiao Li and Xiao Liu again, asking them to show their documents and block the 601 dormitory as soon as possible, so that this matter could not be spread. Wen Qiao also hurriedly notified the others in the 601 dormitory and asked them to come back as soon as possible. Shen Mingyu and Wen Qiao rushed to the 6th floor non-stop, and when they arrived at 601, Xiao Li and Xiao Liu were already standing at the door to maintain order, and there were many girls with unknown circumstances standing in the corridor, and they were gathering to squeeze in to see what the situation was. Seeing that it was getting more and more crowded, Shen Mingyu knew that he should reveal his identity at this time, otherwise it would only become more and more chaotic. He raised his voice, took out his documents, and said: "Everyone, be quiet, I am from the Public Security Bureau of A, and now that a special situation has happened, please go back to your dormitory quietly, don't walk around, please be accommodating." The documents + loud voice are really effective, and the girls who eat melons whisper and return to their dormitories. At this time, the other girls in dormitory 601 were surprised when they heard that Shen Mingyu was from the Public Security Bureau, "It turns out that you are not a repairman, what happened." A couple of girls asked. Liu Qiwei was murdered, you wait outside first, and I'll check on the situation. Shen Mingyu could obviously feel the frightened eyes of several girls, he walked into the dormitory, and found Liu Qiwei leaning back on the chair, with a very eye-catching scratch on her neck, and the blood kept flowing to the ground with her neck. He saw the note written in red pen on the table in front of Liu Qiwei, he realized that the person's so-called revenge had begun, and it was very likely that there would be another victim, he probably checked the scene, and found that the curtains were drawn, and there was no trace of the window opening, and when the window was opened, it was outside, and this was the sixth floor, which basically ruled out the possibility of sneaking in from the outside. Shen Mingyu walked outside the door, explained the basic situation to the girls, and asked the girls not to enter the house for the time being, and wait for the police to come. Wen Qiao took the girls to his dormitory, and Shen Mingyu asked Wen Qiao to comfort them first, while he waited for Han Sicheng to come over.

It didn't take long for Han Sicheng to arrive in a hurry, with big beads of sweat on his face, and it could be seen that he had also run all the way. "What's going on, now, I'll have the forensic doctor do a simple autopsy right away." Han Sicheng asked. "I took a look at the basic situation, it was indeed a throat cut, and the possibility of an outsider breaking in can be basically ruled out, I suspect that the murderer is a woman."

The two chatted with each other about the case for a while, and then the forensic doctor came to report the situation: "The deceased Liu Qiwei, female, 23 years old, the cause of death was excessive blood loss in the major arteries of the neck, died on the spot, there were traces of cutting on the neck with a sharp weapon, no other injuries were found on the body, the body still had residual warmth, and the estimated time of death was not more than 1 hour." "Well, we can already roughly determine the time of death, there were about 20,000 people watching the live broadcast at that time, and according to the audience, the time point when I saw the throat cut was about 1:25, so it shouldn't be wrong." Han Sicheng added. Shen Mingyu suddenly felt a chill behind him, this time the murderer clearly wanted to deliberately cause a riot, but he chose to kill Liu Qiwei when so many viewers were watching when she was watching live, did the murderer have any special intentions? Combined with the information given at the scene and the autopsy report of the forensic doctor, Shen Mingyu analyzed to everyone: "I think the murderer is very careful this time, and the actions are also very cautious, her movements are clean and neat, leaving no traces, and the disguise is also perfect, according to the audience, it is a person wearing a hooded sweatshirt, sunglasses, and a mask, leaving almost no facial features, and because of the live broadcast on the mobile phone, the audience did not see the murderer's whole body, so they could not judge the height of the murderer, It can only be said that she has a big heart. Everyone felt that Shen Mingyu's analysis was very reasonable, and they nodded one after another. Can you still see anything? Han Sicheng asked. Well, there is another point, we have checked the doors and windows, the door is open, because if you don't sleep during the day, the door of the dormitory is almost always open, this has no reference value, although the window is open, but when you open the window, it is outside, and there is no foothold outside, it can almost be ruled out that the murderer entered from the outside, so in this case, the murderer can only enter the dormitory from the inside of Building 7. Because there is a dormitory manager on the first floor, any male who comes in has to pass through the dormitory manager except for me, who has a work permit before, so it is impossible for a man to commit the crime, in this case, the murderer can only be a woman. "Makes a lot of sense! Xiao Shen, well done. Han Sicheng's long-lost praise made Shen Mingyu a little complacent. Oh yes, let me add one more thing, the murderer came in to commit the murder when Liu Qiwei was alone in the dormitory, so this person must be very familiar with the 601 dormitory schedule and going out, otherwise she wouldn't have known that only Liu Qiwei was in the dormitory. "Okay, I'm going to ask the people in the 601 dormitory right away, as well as those who are familiar with Liu Qiwei." Han Sicheng ordered. "Let me ask, after all, I've been in contact with them for a few days, and I know a lot about them, Wen Qiao and I happened to be at the express station outside the school at the time of the crime, and the two of us should be able to rule out the suspicion of committing the crime." Han Sicheng saw that Shen Mingyu was so serious, and decided to let him question.

Shen Mingyu came to the 603 dormitory where Wen Qiao was, and several girls were sitting on the side with anxiety, without saying a word. Shen Mingyu comforted, "Don't be afraid, now the police will protect everyone's safety, I need to ask you a few questions, so that we can find out the murderer as soon as possible, so that you can return to your original life." "But...... How to recover, Sister Qiwei is already dead......" Zhang Muru said in a low voice. Shen Mingyu was speechless for a while, and he didn't know how to answer. Wen Qiao saw Shen Mingyu's embarrassment, and she relieved the siege: "It's okay, Sister Qiwei must also want to find that person in the sky, let's cooperate with Brother Xiao Shen well." Wen Qiao's tone was very gentle and healing, and at this time, Lan Yingxue, who was the cow of the society, was the first to stand up, "Brother Shen, you ask me first, and I will tell you the truth." Shen Mingyu saw that someone took the initiative to stand up, and his tone was much softer, "Okay, you don't have to be nervous and afraid, it's just an ordinary question, it won't be good, Yingxue, then let me ask you, what time did you leave the dormitory today, what did you do after that, did anyone come with you, and then what time did you return to the dormitory, can you tell me." Lan Yingxue replied, "Hmm...... I left the dormitory at half past eight o'clock, because I have an English competition to participate in a few days, so these days I will review in the library, like usually Monday to Friday is to make an appointment will be recorded, but today is the weekend without an appointment, so there is no record, I went alone, today is also sitting on the second floor of the usual seat, no one seems to be able to help me prove, I went to borrow a reference book at half past 10, there is a record of borrowing, around 12:50 I went to eat, I ate the north and south flavor of this shop, I have a record of payment, and then when I was about to finish eating, Wen Qiao called me and said that something had happened, and asked me to come back quickly, so I came back directly, and you were already there when I came back. "Yingxue, I know, you did a good job, who wants to answer next." Shen Mingyu asked. "Brother Shen, let me answer." Zhang Muru said. "I made an appointment with my girlfriend from the law department today to go to the botanical garden, we set off at 8 o'clock in the morning, I should have come out of the dormitory at 7:50, everyone was still in the dormitory when I went out, I should have been the first to go out, we went to the botanical garden by shared tram, it should have been around 8:30 to the botanical garden, and I walked around until 10:30 o'clock, my girlfriend suddenly had something to go back to school, but I thought it was too early, so I walked around the botanical garden by myself, because there were more people in the botanical garden this weekend, Maybe no one can help me prove it, I was thirsty and bought a bottle of drink at the vending machine, about 11:40, mine also has payment records, and then Sister Wen Qiao suddenly called me and said that there was something, I came back from there, because the taxi is too expensive, I took that kind of tricycle back, it can be half cheaper, but now I shouldn't be able to find that uncle, you are already there when I arrive. "Okay, thank you, Muru." At this time, Han Sicheng came in, he quietly pulled Shen Mingyu outside the corridor, and whispered in his ear: "An important clue has been found." ”
