Two days later, when Ran Sinian went to the hospital early in the morning and was about to pick up Rao Peier as a pseudo-boyfriend, Qu Zichong called and informed Ran Sinian that the plan to wait for the rabbit was successful, and they had waited for Xia An'an and Pei Jian at the place designated by Ran Sinian, and now the two of them have been taken to the criminal investigation detachment of the city bureau. It is expected that before noon, several other people involved in the case can also be brought in, and if nothing else, in the afternoon, Ran Sinian can be in the conference room, in front of everyone, to uncover the mystery of a series of cases.

Ran Sinian specially asked Qu Zichong if Tian Jing could be present, because this Tian Jing's identity is relatively special, in case people don't appreciate their face and refuse to come this time, the reasoning drama in the afternoon will definitely be much inferior.

As a result, Qu Zichong's answer was quite satisfactory to Ran Sinian, it turned out that Qu Zichong had contacted Tian Jing's lawyer early in the morning, and had reached an agreement with the lawyer, and it would not be a problem to let Tian Jing and the lawyer come forward in the afternoon.

Ran Sinian hung up the phone and continued to help Rao Peier pack her things and prepare to go home.

As soon as Rao Peier heard that the truth of all the cases would be revealed in the afternoon, she said that she would follow Ran Sinian to say anything, saying that she herself was also a victim of a series of cases and had the right to know the truth. Ran Sinian originally disagreed with Rao Peier to join in the fun, but Rao Peier had completely entered the play and became a domineering girlfriend, pouting and stomping her feet and twisting her body after a series of coquettish actions, Ran Sinian had no choice but to surrender.

After lunch, Ran Sinian drove Rao Peier and Liang Yuan to the criminal investigation detachment of the city bureau.

After one o'clock, a lot of people had gathered in the conference room: first of all, Xia An'an and Pei Jian, who first entered Ran Sinian's life, and who also brought this series of events, the two of them sat together, still wearing the clothes they had when they went to Ran Sinian's house, and Xia An'an still had the iconic straight black hair, Pei Jian's figure was thin, the combination of these two, Ran Sinian could be immediately identified even though he was face blind; According to the chronological order of appearance, sitting next to them happened to be the Mi Yueqi who posted a video on the Internet and insisted that she was not Xiaoqian and was still a virgin, and Ran Sinian also recognized her at once through her hairstyle and the mole on her nose; Mi Yueqi is opposite Tian Jing, a tall and wealthy second generation suspected of poisoning, and his lawyer, one is tall and strong, the other is in a straight suit, naturally they are the two of them; Next was Zhao Guozhong, the husband of the deceased Wang Xiaoyu, who was immediately recognized by Ran Sinian by the Mediterranean Sea above his head as a marker; Sitting next to Zhao Guozhong turned out to be the leader of the Normal University, the principal of the Normal University who wore thick glasses and was slightly blessed, which surprised Ran Sinian, and he didn't specifically invite this busy man, how could Qu Zichong invite him on his own initiative? Ran Sinian's puzzled gaze swept to Fan Xiao, who was sitting next to Qu Zichong, and immediately understood that it was up to the principal to invite him, and it should be Fan Xiao's insistence. Fan Xiao sat next to Qu Zichong, holding the small notebook and pen, ready to record his study.

"Who is this?" Ran Sinian sat in the reserved position on the other side of Qu Zichong, and asked Qu Zichong who the strange middle-aged woman sitting next to him was, Ran Sinian was sure that in this series of cases, he had never seen this woman.

Qu Zichong introduced: "This Ms. Lin Fang is Jiang Jing's mother, Si Nian, since you said that you can solve the truth of all the cases today, I think it is necessary for me to ask Ms. Lin to come and give her an explanation." ”

Ran Sinian nodded, then turned his head and nodded to Lin Fang.

Behind Ran Sinian, Liang Yuan moved two chairs and sat down side by side with Rao Peier.

Qu Zichong saw that everyone had arrived, cleared his throat, and signaled the people in the conference room to be quiet. After a few seconds, Xia An'an and Pei Jian stopped talking in a whisper, Tian Jing and the lawyer also stopped talking, and more than a dozen people looked at Qu Zichong, who was in the position of the host of the conference table.

"I invite you to come today, the purpose is very clear, that is, to reveal the truth of a series of cases and events that have occurred in the recent period," Qu Zi rushed straight to the point, as a leader who does not know the answer so far, he is quite confident, "I believe that everyone knows each other without my introduction, this is Mr. Ran Sinianran, the consultant of our criminal investigation detachment, for this series of cases, Mr. Ran has been following up and investigating, and he will uncover the mystery for you and reveal the identity of the real murderer." ”

As soon as Qu Zichong's voice fell, an abrupt and embarrassing voice came out of the conference room, and it turned out to be Fan Xiao clapping.

Qu Zi glanced at Fan Xiao, and Fan Xiao had to put down his hand awkwardly and smiled dryly.

Everyone's eyes were focused on Ran Sinian, but Ran Sinian was not nervous at all, but smiled lightly and said: "In scientific research, often when a problem cannot be solved, you might as well add another problem and consider it together, but sometimes you can find unexpected solutions." It's like if you put two walnuts together and break them apart is easier than breaking them apart. This sentence is a famous quote of Sigmund Freud, and it is this sentence that reminds me that a series of seemingly unrelated events and cases that have occurred in recent times are actually closely related, and it is difficult to explain them comprehensively if you analyze and study them one by one, but if you connect them all together, you will unexpectedly find that these events are nothing more than branches of a well-planned plan made by one person. ”

"Alone? Are you saying that the mastermind in all cases is one person? Fan Xiao exclaimed, his face was not very good-looking, obviously Ran Sinian's statement did not coincide with what he thought in his heart, but contrary to what he thought, "How can it be a person?" ”

"It's a person, and this person is in this room right now." Ran Sinian said, his eyes swept over the faces of everyone who couldn't tell the difference in his eyes.

Ran Sinian's words caused a small commotion in the conference room, Xia An'an and Pei Jian, Tian Jing and the lawyer, the two pairs, whispered to their companions, and the rest of the people said to themselves that they wouldn't do it, and some looked at the others vigilantly.

"Then, let's start reasoning from the last murder case," Ran Sinian calmly began to explain, "The last Wang Xiaoyu case seems to be the most incredible murder case, because of the place and time it happened, as well as the situation of the crime scene and the body, all of which express a theme, that is, the murderer who killed Wang Xiaoyu was not a person, but the legendary night demon. ”

"That's right, we also found wolf hair in Wang Xiaoyu's wounds, and Wang Xiaoyu's body was in tatters, and there were claw marks that looked like wild beasts everywhere. After forensic identification, the depth and curvature of the wound can be confirmed, which is indeed the mark left by the wolf's claw, not imitated with a sharp weapon. There are also footprints left at the scene, according to the depth of the footprints and the distance between the footprints, it can be inferred that the murderer is a monster with a height of more than 1.9 meters and a weight of more than 150 kilograms," Fan Xiao reminded Ran Sinian, "All kinds of signs show that the murderer of Wang Xiaoyu is a monster that walks upright, half human and half beast, similar to a werewolf!" ”

Qu Zichong coughed vigorously to stop Fan Xiao from continuing to state the forensic identification results in such an exaggerated tone, and then added his own subjective speculation.

Ran Sinian nodded in agreement with Fan Xiao's opinion, "That's right, on the surface, that's exactly the case. But there are no Daredevil in this world, or rather, at least there won't be any Daredevil or half-human, half-beast monsters in the woods near the university town. It was a person who killed Wang Xiaoyu, no matter how ordinary he was, as for the footprints and claw marks, they were all forged by this person. ”

"Forgery? How to fake? This time, Xia An'an didn't suppress her curiosity and asked Ran Sinian.

"Let's talk about footprints first, that's right, the weight of the murderer can be estimated according to the depth of the footprints, and the height of the murderer can be estimated according to the distance between the footprints, of course, the premise is that the murderer is a person." Ran Sinian explained.

"That's right, the premise is that the murderer is a person," Pei Jian suddenly thought of something and expressed his opinion, "Because it is estimated according to the proportion of the human body." If it's a monster with a long lower body and a short upper body, or a monster with a short lower body and a long upper body, of course, you can't estimate your height based on the distance between your footprints. ”

Ran Sinian waved his hand and said to Pei Jian: "You misunderstood what I meant, the focus of what I just said is not on 'people' but on 'one'. In other words, if the murderer is not one person, but two people, and one of the murderers carries the other murderer, then it is meaningless to infer the weight of the murderer by the depth of the footprints, but it is still meaningful to infer the height of the murderer walking on the back of the other murderer through the distance between the footprints. ”

Qu Zichong was the first to understand what Ran Sinian meant, "Si Nian, are you saying that our speculation about the height of the murderer is correct, assuming that the murderer has two people, A and B, and the murderer A walks with the murderer B on his back, what can be estimated is the height of the murderer A, but the weight is inaccurate, the so-called 150 kilograms is actually the sum of the weight of the two murderers A and B?" ”

"That's right, according to the footprints at the scene, we know that the murderer is about 1.9 meters tall and weighs more than 150 kilograms, and we know that the murderer will not be a monster like a monster like a disproportionate night demon werewolf, and then rule out that the murderer is a tall and fat man who weighs more than 300 pounds, after all, there are still very few people with such height and weight, and the most likely thing is that the murderer is two people, one of whom is more than 1.9 meters tall and walks to the grove with the murderer B on his back. Assuming that Murderer A is 1.9 meters tall and weighs about 100 kilograms, then it can be inferred that Murderer B weighs about 50 kilograms. ”

Fan Xiao exclaimed excitedly: "Mr. Ran, you just said that the murderer is in this conference room, so that means that the murderer B is one of the people in this room who weighs about fifty kilograms?" ”

"Yes, but of course the two ladies behind me must be excluded, one of them is a policewoman and the other is my girlfriend, of course Murderer B can't be one of them." When Ran Sinian talked about his girlfriend, he looked at Qu Zichong and Fan Xiao with a smile, and sure enough, he saw surprise on the faces of these two people.

Qu Zichong put away his surprised look at the first, returned to the topic, and said, "The people in the conference room who weigh about fifty kilograms should be two young ladies, Xia An'an and Mi Yueqi, right?" ”

Ran Sinian looked at Pei Jian and said, "No offense, Mr. Pei, may I ask what your weight is?" ”

Pei Jian scratched his head embarrassedly and said, "Fifty-four kilograms." ”

Ran Sinian nodded, and turned to Qu Zichong and said, "Then there are three people in the suspected range of murderer B, namely Xia An'an, Pei Jian and Mi Yueqi. As for the murderer, I don't think I need to say more, everyone knows it. ”

Tian Jing's lawyer sneered and said: "Mr. Ran, if you want to accuse my client, please come up with evidence, such a subjective and speculative slander of my client, we reserve the right to pursue your responsibility." ”

Ran Sinian shrugged innocently, "Mr. Lawyer, I didn't name names, did I?" And, how can you assume that I have no proof? This part of the evidence, I was about to say. ”
