After the two came out of the scene of the crime, Han Sicheng saw Shen Mingyu's thick dark circles and tired expression, so he asked Shen Mingyu to rest first tonight and take care of it himself. Shen Mingyu was indeed tired, he dragged his tired body back to the abandoned dormitory, and the girls couldn't sleep because they saw the terrifying scene before, and sat without saying a word. When they saw that Shen Mingyu was back, they hurriedly asked about the progress of the case, but Shen Mingyu had no choice but to answer them: "Students...... I'm sorry, it's still under investigation, I'm sorry, it's all because I didn't find out earlier......" "You're embarrassed to say, what's the use of you police!" What the hell does the Public Security Bureau do! Everyone leaves one by one, and maybe it will be the next turn! Rui Yi shouted in a slightly crying voice, and it could be seen that she was on the verge of a mental breakdown because of these two events. Shen Mingyu was speechless, he could only repeat over and over again "I'm sorry, I'm sorry, I'm sorry......" Shen Mingyu felt desperate at this moment, he found that he was completely played by the cunning murderer in applause, he actually had the idea of retreating in his heart, it was only more than two months, he encountered this kind of big case, originally he thought that he was very strong in resisting pressure, but now he found that he was nothing, the spirit of the first case before was also missing, and all that was left was endless pain, The feeling of the people you protect disappearing one by one in front of your eyes is really too tormenting. Wen Qiao comforted the girls on the side, trying her best to ease the atmosphere, but everyone still didn't say a word. I don't know how long it has passed, Rui Yi calmed down and apologized to Shen Mingyu: "Brother Shen, I'm sorry...... I, I, was so excited just now, I didn't mean to say that. "It's okay, it's really my mistake, it's my bad one." Shen Mingyu replied weakly. At this time, Wen Qiao came out to be a peacemaker, "Everyone is very tired today, rest first, and talk about it tomorrow." ”

In the early morning, it rained lightly outside the window, and everyone stayed awake all night, and their mental state was very poor. Wen Qiao found that yesterday's jumping incident had spread in the school, and the incident was being discussed everywhere in the post bar, forum, Weibo, and circle of friends, and now the whole school was panicking. Han Sicheng realized the seriousness of the matter and asked the bureau to send more manpower, Lin Guang knew that the situation was urgent, and immediately mobilized manpower to the University of Finance to support. Despite the homicides, the school was reluctant to close because the cost of closure was too high and the students had to continue their classes. Han Sicheng had to arrange police forces in various parts of the school to ensure everyone's safety. The people in the 601 dormitory also have their own compulsory courses, so they must also go to class, Shen Mingyu is helpless, he can only disguise himself as a student and go to class together, but everyone in the dormitory has a different major, Shen Mingyu is struggling with who to go to class, so he asked the girls about today's class: "How many classes do you have today, where do you go to class?" The girls replied one by one. Wang Xiaomeng wants to go to the chemistry laboratory to do experiments, Rui Yi wants to go to the 2nd floor of Building B to take classes, and Zhang Muru, Ning Lin, and Wen Qiao are all in Building A, but the floors are different. Shen Mingyu decided to follow Rui Yi to Building B, and then let Xiao Li wear civilian clothes to guard the pavilion in front of the chemistry laboratory, while Building A was guarded by Han Sicheng and two police officers in the reading corridor downstairs.

Shen Mingyu sits in the last row of the classroom, and usually the students and teachers in the last row do not listen to the class by default and will not care about them. Rui Yi sat in the middle position, and Shen Mingyu could just see the back of her head. This class is college Chinese, Shen Mingyu didn't like to listen to Chinese classes when he was in high school, because the Chinese was boring, and he could do well if he didn't listen to the class, plus the high school Chinese teacher's voice was very gentle, and he wanted to sleep every time he heard it. After many years of listening to Chinese classes again, Shen Mingyu was as sleepy as ever, coupled with the lack of rest time in the past two days, his spirit was seriously overdrawn, and he could only rely on willpower to support him. I don't know how long later, he heard the bell for recess, because the first class at the University of Finance would be extended by 10 minutes to allow students who had missed breakfast or needed to go to the toilet to have plenty of time to do their own things, a rule that had been in place for nearly 10 years and had been widely acclaimed. Most of the students lay on the table and chose to take a nap, while a few students went to the corridor to blow the wind for a while, or went to the toilet. Shen Mingyu also came to the corridor to blow the wind to sober himself up, and suddenly, he saw Rui Yi hurriedly walking towards the corridor. Shen Mingyu also hurriedly followed, but he found that Rui Yi just went to the toilet in the corridor and breathed a sigh of relief, because the women's toilet near the classroom was already lined up at this time. There is usually one men's toilet and two women's toilets on the first floor of the teaching building of the University of Finance, but because the second women's toilet in the B teaching building is far away and dirty, female students generally do not go to the toilet inside if they are not in a hurry. Rui Yi's face was frightened, and she followed the message on her mobile phone and went to the agreed place - the women's toilet on the second floor. Not long ago, Rui Yi received an anonymous text message, the person above said that he already knew the truth about what had happened recently, and also knew the secret of the 601 dormitory, if he didn't want anyone to have an accident, he would come to the women's toilet on the second floor to discuss countermeasures. Rui Yi knew that it might be dangerous if she went to the appointment, but at this time her fear overcame her reason, she was worried that it would be her turn next, and she couldn't care so much at this time, so she decided to go to the appointment. Rui Yi came to the women's toilet and found that the door was ajar, she walked in and whispered, "Is there anyone?" I came here as you said, who are you, don't you mean to discuss ......" Rui Yi's words did not fall, only to see someone strangled her neck from behind with a wire-like object, she instinctively protected her neck with both hands, but the power of the wire and the strength of the murderer were too great, and in less than a minute, Rui Yi completely lost her breath. After seeing Rui Yi unconscious, the murderer took out a bundle of rope that had been placed in the toilet beforehand, moved the chair that had been in the toilet for a long time, and hung Rui Yi on the ceiling. Subsequently, the killer put a note on the chair and quietly left. The note read: The third, revenge.

Wang Xiaomeng is doing experiments in the chemistry laboratory, she is a top student in the Department of Chemistry, her classmates have a high evaluation of her, and the teachers also value her, she has won all scholarships, and has won many honors and awards. She recently won an award in order to complete a project, and she has been busy recently, if she gets the award, it means that she is one step closer to the qualification of the research institute, she cannot slack off, and must continue to work hard. Wang Xiaomeng likes to do experiments in the fifth laboratory at the end of the corridor, which is small but well-equipped, and quiet and undisturbed, so that she can immerse herself in her own chemical world. The classmates laughed and said that the laboratory was surnamed Wang, and it should be renamed and changed, and the teacher also teased her, you are the director of the laboratory, and handed her the key, and when she wanted to do the experiment, she opened the door and went in by herself. Wang Xiaomeng locks the door of the laboratory, which is her usual style, and she doesn't want to be disturbed by external things when she is doing experiments. She was engrossed, completely unaware that death was coming, an inconspicuous corner, suddenly appeared zero point Mars, Wang Xiaomeng still put herself into the experiment without looking back, and the sparks evolved into flames, constantly devouring the surrounding items. A fire in a chemistry laboratory, everyone knows, what the consequences will be. Wang Xiaomeng finally felt that something was wrong, she felt a strong smell of smoke, and it was not caused by the experiment, she looked back and saw that the flames had evolved into fire snakes, like prey and rushing in all directions of the laboratory. Wang Xiaomeng realized the seriousness of the problem, she hurriedly went to the wall to get a fire extinguisher, but at this time, the fear psychology had made her behavior chaotic, she took it several times, but she didn't take the fire extinguisher down. So she gave up putting out the fire, instinctively ran towards the door, and when she came to the door, she twisted the doorknob and found that it could not be opened, and she was in despair, and she had completely forgotten that she had locked the door with her own hands. In this way, Wang Xiaomeng came to an end in a sea of fire. Next to the big tree in front of the chemistry lab building, there is a wooden board with the words "Another revenge."

The class bell rang, and Shen Mingyu found that Rui Yi hadn't come back yet, she had been too long, did she have a bad stomach? Shen Mingyu muttered in his heart. A few minutes later, he heard a loud scream, and he sensed that something was wrong, so he rushed out of the classroom, and several boys rushed out with him. When he came to the hallway, he found the aunt in charge of cleaning sitting at the door of the toilet inside, looking terrified. He ran over with a few boys, and he asked his aunt what had happened, and with a frightened expression, the aunt pointed to the inside of the toilet and said, "Someone is dead inside!" Shen Mingyu felt a thunderbolt from the sky, but he had to calm down, at this time there were already many people gathered in the corridor, all of them were teachers and students who had just heard the screams, he asked a few male classmates who came with him to help maintain order, not to let others get close to the scene, and at the same time he called Han Sicheng and asked him to come over quickly. I'm looking for you too, what's going on over there? Xiao Li just told me that there was a fire in the chemistry lab! The fire truck has been notified to come to the rescue, so hurry to the chemistry lab. Shen Mingyu was stunned and stayed where he was. Hey, what's wrong, are you listening? On the other end of the phone, Han Sicheng asked over and over again. Shen Mingyu came back to his senses, he picked up the phone, and said to Han Sicheng: "I think you should come to my side first, the women's toilet on the second floor of Building B by the corridor, Rui Yi is dead." Han Sicheng was also stunned after hearing this, there were incidents on both sides at the same time, how did this happen? Although Han Sicheng was very puzzled, but now that the fire in the chemical laboratory has not been extinguished, he can only go over to find Shen Mingyu first, after he finished instructing his police officers, one wave will stand by and continue to guard Building A, and the other wave will go to support the chemical laboratory, and he will take two police officers to run towards Building B.

Shen Mingyu came to the toilet and found Rui Yi hanging from the ceiling, because the forensic doctor had not yet come, so he could only observe the situation around the scene for the time being, because this women's toilet was rarely used, and the aunt would clean it every three days, so this toilet looked exceptionally clean, there was no trace of a fight at the scene, the window was open, but the windowsill did not leave any traces, so it can be ruled out that the murderer entered the women's toilet from the outside, leaving a very thick wire next to the body, and the shape has been bent or even deformed. Shen Mingyu analyzed, Han Sicheng arrived, and it could be seen that he was also surprised, "Let the forensic doctor conduct a preliminary autopsy first, and let's go outside to talk." "Okay, let's ask the aunt who found the body." When they came to the corridor, the police officers had already let the students back to the classroom, Shen Mingyu thanked the boys who helped to maintain order just now, and turned back and asked, "Auntie, can you please tell me about what just happened?" The cleaning aunt was shocked, but she was still willing to cooperate, saying: "My job is to be responsible for the cleaning of the toilet in Building B, which is usually disinfected once every three days, cleaning the things in the toilet, cleaning it once a morning, and I usually go in when the students are in class." Just now I heard the class bell ringing, began to clean, I usually start cleaning from the toilet on this side of the corridor, because there are few people here, it is faster and more convenient to clean up, I just entered the toilet, I found a girl was hanging from the ceiling, I was very scared, I don't know if she is dead or alive, instinctively shouted out, and then you rushed over. "Okay, I understand, thank you for your cooperation." Shen Mingyu said. "Oh yes, Auntie, was there a rope in the toilet before, and was the chair in the toilet before, do you usually clean the second floor at a fixed time." Shen Mingyu thought of some details and continued to ask. "I usually clean from the first floor upwards, usually almost every day at this point in time, I didn't see the rope when I cleaned yesterday, the chair was placed in the toilet before, because it leaned against the corner and didn't take up space, so I didn't take the chair out." "Thank you for your cooperation." At this time, the forensic doctor asked them to come over and issued a preliminary autopsy report: the deceased Rui Yi, female, the cause of death was breathing disorders caused by mechanical asphyxiation, and there was a strangulation mark on the neck, that is, strangulation. No other wounds were detected on the body, there were obvious strangulation marks on the palms of both hands, and the time of death was about an hour ago, and we found that the wire on the ground had human fibrous tissue, and the preliminary judgment was that the murder weapon was this thick wire. Everyone looked at Shen Mingyu, waiting for him to express his opinion, Shen Mingyu thought for a moment and gave his own conclusion: "This case is related to the previous two, this case The murderer also left a note at the scene, the deceased should have been attacked from behind, and then instinctively covered his neck with both hands, so there were also strangulation marks on his hands, after confirming the death of the deceased, the murderer used a rope and a chair to hang the deceased up, from this point of view, the murderer's strength should be much greater than that of ordinary girls, and it can even be compared with boys, But what is her intention in doing this, this has not happened in the first two cases, she can obviously strangle the deceased and flee directly, but she took great pains to prepare a rope in advance after cleaning, so I feel that this should be the murderer who has experienced such a thing or that she must use this method to get revenge. Han Sicheng agreed with Shen Mingyu's idea, "I think that's the case, otherwise there is no need to hang someone again after killing someone, I guess this should be one of the contents of revenge." As soon as he finished speaking, his phone rang, and Xiao Li's voice was on the other end of the phone, "Team Han, the fire is out, come over quickly." Han Sicheng asked the two police officers to stay and guard the scene, and the other details had to wait for the reports of the forensic personnel and the on-site investigators, so he and Shen Mingyu rushed to the chemical laboratory.

The two arrived at the chemistry lab, the fire had been extinguished by firefighters, but the entire chemistry lab was unrecognizable, almost everything was burned, and the most fierce fire was the fifth laboratory, which was furthest from the corridor. After the investigation of the firefighters, it was confirmed that the fire started in the fifth laboratory, and they also found a body with an abnormally serious degree of burn from the fifth laboratory, the body had been charred, but fortunately, there was still some skin tissue left on the inside of the arm, Han Sicheng immediately sent someone to extract the DNA on the skin tissue and send it for testing and testing to determine the identity of the deceased. Although the identity of the deceased has not yet been determined, Shen Mingyu feels that the deceased is Wang Xiaomeng who was doing experiments in the chemical laboratory, Xiao Li saw the two of them arrive, and ran over to report the situation: "Team Han, just now I was in charge of squatting in the pavilion, and suddenly found black smoke coming from the laboratory, I ran over to see that it was a fire, so I immediately called the fire brigade to come over, and notified you by the way, but this side is far away from the faucet, we can only take buckets to transport water back and forth, after all, it is a chemical laboratory, there are a lot of flammable and explosive products, The fire burned so fast that it burned out in a few minutes. "Did you see anyone else passing by the lab?" Shen Mingyu asked. "No, this side is far away from the dormitory and the teaching building, I asked the school guards, usually except for the students of the chemistry department who come to do experiments, no one will come here, you can ask the patrol security guard." "Thank you, Xiao Li, you continue to assist the firefighters and forensic doctors at the scene, let's go find that uncle." Shen Mingyu and Han Sicheng were about to go to the security room to find the patrolling uncle, they passed by the big tree at the door of the laboratory, and found the wooden sign with the words written on it, the two glanced at each other, Shen Mingyu took a photo, and asked the forensic staff to take the wooden card for analysis. "Sure enough, this is also the ghost of that person, but how did she manage to kill two different people in two different places almost at the same time?" Han Sicheng showed doubts. "There won't really be a shadow clone in this world, if it weren't for this, it would be impossible to commit a crime, could it be that he is Naruto Uzumaki?" Shen Mingyu was also confused, and replied randomly. "Did you faint yesterday and now your brain is not sound, if she is Naruto Uzumaki, then I am Detective Conan." Han Sicheng said. "You're a bird-like Detective Conan, and you're just a twilight officer at most." (Officer Twilight is a character in Conan, which can be called the pinnacle of lying down to win, every time the police go out to the police, it is the Conan Gang to solve the case, and he only needs to close the case and leave work.) Shen Mingyu's tone was not weak. Han Sicheng didn't bother to care about him, and quickened his pace.

Coming to the door of the security room, the uncle was sitting in it leisurely drinking tea, Han Sicheng identified himself and asked, "Uncle, I heard that you are in charge of patrolling the laboratory every morning, did you find anything abnormal today?" The uncle replied: "No, there is no one over there, let alone early in the morning, I haven't even seen a single hair, but today there are two people sitting in the pavilion and don't know what to do." "Well, that's our colleague." Han Sicheng said. Shen Mingyu showed the uncle the photo of the wooden sign he had just taken, "Uncle, have you seen this wooden sign when you were patrolling today?" The uncle put on his reading glasses, looked at them carefully, and after a while, he said: "Oh, this card, I've seen it, it's been there since yesterday, I can't read the words on it, I'm worried about who fell, so I don't care." "That's right, thank you, uncle." Shen Mingyu got an important clue and pulled Han Sicheng out of the security room. Shen Mingyu analyzed to Han Sicheng: "The murderer put the wooden sign at the door of the laboratory in advance, which shows that she is very aware of Wang Xiaomeng's schedule and schedule, and she knows that Wang Xiaomeng will definitely come to the laboratory today, so she put the wooden card next to the tree in advance yesterday." Although I don't want to believe it, the murderer is likely to be the person next to Wang Xiaomeng, but it's just ...... I haven't figured out her modus operandi yet, but can she really kill two people in different locations at the same time......"
