Crime requires attention to the cost of crime, as well as the relationship between the motive and driving force of crime. To put it simply, the cost of committing a crime should be equal to the benefit of the crime you obtain. The higher the benefits of crime, the higher the cost of crime.

For most crimes, the higher the cost of crime, in order to achieve the success value, it is bound to be more cautious, and even think of killing with one blow. Therefore, you can find that many violent crimes generally have no prelude, and the offender often has a direct result of the victim, and there is not even a little warning for the victim before.

Thought, for a person who has a relatively low requirement for the outcome of a crime, he also does not care about the process of committing a crime. So, the lower this psychological threshold, the faster and more direct the impulse is created, and the sooner something is released. That kind of accumulated crime doesn't happen.

Yang Minzhi summed it up for me: "The accumulation of crime will lead to the exposure of crime. If the threshold is lower and does not lead to accumulation, there will be much less violent crime. Zhang Shuya's description mentioned that those people had some small festivals with her father, and these small festivals were considered to be things with low thresholds, and they were easily released. Naturally, the most direct way is to start with your hands and have a physical altercation. On the contrary, Zhang Pengsheng and Zheng Tongyi were really enemies at that time. And what Zheng Tongyi did was almost to put people to death. In the process of adding Zhang Shuya's description of his father, he said that Zhang Pengsheng has been thinking about countermeasures, and more forbearance is in line with the characteristics of the increase in the threshold value. Therefore, once he goes to Zheng Tongyi, either nothing will happen and he will leave directly, or he will not cause the previous physical injury at all, and he will directly end up with the result. ”

"Minmin's analysis is what I want to say, so based on the analysis of these situations described by Zhang Shuya, we exclude other factors that have not yet been considered, and according to the criminal psychological analysis, we can basically infer for the time being that the physical injuries on Zheng Tongyi's body before his death should not be Zhang Pengsheng's doing. In other words, before the fire broke out at Zheng Tongyi's factory, there may have been people who entered the factory and had a fierce conflict with Zheng Tongyi. This conflict even led to the ensuing fire, and led to the death of Zheng Tongyi, and if Zhang Pengsheng is not guilty. When Zhang Pengsheng went to find Zheng Tongyi, the person who caused Zheng Tongyi's physical injury was even in the factory. ”

Yang Minzhi said: "Very likely. It's just that so much time has passed, and we are abroad, we can't get first-hand information about the scene at that time, how to find out now, the potential suspect at the scene. ”

There is no doubt about the case analysis. Here Yang Minzhi and I are the best at it. And others, such as Ma Tianhang, Wan Kelin and even Cheng Yuan, are staring at us, and it is difficult to speak for the time being. Only Zhang Shuya, after all, has re-intervened in her father's case from beginning to end, and her IQ is extraordinary, so she can keep up with our analysis: "If according to what you said, at the same time that my father went to Zheng Tongyi, there should be another person in the factory." , and this person must have some festivals with Zheng Tongyi. In my memory, there were a few of them. ”

"I need you to introduce the situation of these people in detail, the more detailed the better, because any little clue may be the clue to solve the case in the end."

I think that among the many cases I have come into contact with, this case is absolutely unique. First of all, this is a case that was convicted by the police sixteen years ago, and we need to overturn the police's presumption of guilt and reverse prove innocence! Secondly, because of our special situation, we are unable to obtain first-hand information from China, nor can we reach out to the people who are still alive in the world as much as possible, so we can only aggregate all possible information. Once this information is aggregated, we have to move on to the most critical part.

This link is, the palace of thinking! When I was on Shengguang No. 1, Yang Minzhi and I conducted a thinking palace, but at that time, my thinking palace analysis was still very simple, that is, based on the information we knew on the ship, and conducted a hypothetical analysis. Because there are many conditions, but there is very little content to think about, so basically it will not deviate from the final answer.

But this time, because the age of the event is very long from the present, and the information is limited, once we enter the palace of thought, we are faced with many unknown plot hypotheses. And the appearance of any unknown plot hypothetical will inevitably make more rooms appear in the palace of thinking.

As I mentioned earlier, when the more rooms appear in the palace, the amount of memory and analysis increases exponentially. Because, you need to fantasize about the content of the analysis.

In Sherlock, Sherlock Holmes uses the palace of thought to analyze the case, and even puts himself in a state of complete confusion, and as a last resort, he uses drugs to indulge himself in the palace and does not come out, so as to expand the palace of thought as much as possible to find the final answer.

As a senior staff member of the Ministry of Public Security, Cheng Yuan is naturally better at writing these things. So when Zhang Shuya recounted the information of those suspects in detail, Cheng Yuan and Wan Kelin kept there to record.

Taking advantage of this opportunity, Ma Tianhang and Yang Minzhi came out with me. Because Yang Minzhi knows that the next amount of brain usage will be very large, and it will make people nervous, and they need to relax in advance.

Yang Minzhi said sincerely: "I think this matter is too difficult, if you need to think about the palace analysis, you may not be able to do it alone." ”

"I think so too." It's not that I'm not confident, but I'm telling the truth.

Ma Tianhang pointed at the two of us: "Then the two of you are together." ”

"Heh, you, you don't understand anything, just interject here." Yang Minzhi glanced at him with disgust and said, "Do you think it's really like in the Inception movie, finding an instrument can unite each other's dreams and shape everyone in the same dream space?" If this is really the case, it is naturally the best, I will enter the thinking palace with Junliang, and it will be much easier for everyone to assume together. But now, none of them can perfectly intersect two people's dreams or thoughts and fantasies. Let two people perform tasks in the same mind, fantasy or dream world! It's not sci-fi, it can't be done. Therefore, Junliang and I can only shape the palace of thinking separately. Moreover, whenever we encounter a misunderstanding of thinking, we have to come out of the palace of thinking immediately. At the same time, the two of us had to record every step of our thinking. Every time we wake up, we have to look at each other's progress. In this way, the next time we enter the palace of thinking, we will bring in the palace that the other party has simulated in advance. ”

"It's so complicated." Ma Tianhang shrugged his shoulders helplessly, "I think, I'm still my pirate comfort." ”

"Everything is not that simple, but this time, we do need Zhang Shuya's cooperation, so we have to do everything possible to complete the inference of her father's innocence. As long as we can complete the inference of innocence on Zhang Pengsheng and find enough evidence to support this inference. That Zhang Shuya will inevitably compromise. When we recover our identity and return to China, we can naturally clear her father's guilt. ”

"Now I understand that those of us who use our brains are also very hard."

Ma Tianhang shrugged his shoulders again: "Okay, okay, both of you have worked hard." Is there anything I need help with? ”

Speaking of help, I must first need me and Yang Minzhi to enter the role of the Thinking Palace.

In fact, because Zhang Shuya's father's case is too complicated, if Yang Minzhi and I come to enter the thinking palace of that case from the beginning, we will inevitably put ourselves in a state of chaos. It's like you haven't done a test paper for your third year of high school for a long time. Suddenly, after a half-year break, I got a simulated mention again, and I was absolutely blindfolded!

"I think we'll all have to do a warm-up, especially you." Yang Minzhi pointed at me, "It just so happens that there is a certain fire case that I have been exposed to before in my mind, so why don't you use this to simulate it first." ”

This is naturally the best thing, Yang Min has a superior IQ, and she will not involve too simple fire cases, but she also naturally understands that too complex cases will definitely make me more confused at this stage. She chose a case of moderate difficulty and asked me to warm up in the palace of thought, which was the best policy.

In front of me, Yang Minzhi gave a general explanation of the situation of this case, and at the same time, some key points were also written on paper, after all this was done, I needed to quickly summarize the information and bring it into this case, in short, I need to enter the world of the protagonist of this case from my world, and start to enter the palace analysis from the perspective of the party involved in the fire.

According to Yang Minzhi's arrangement of test questions, at this time, in the perspective of my thinking palace, my identity is a news reporter. And I got a call from a boss that day, inviting me to a restaurant for dinner. That boss and I know each other, and I don't think I will refuse! Everything that follows is what Yang Minzhi told me in advance, and there is also the content that I started to simulate in the palace of thought.

I drove to the hotel. As soon as I went upstairs, I found that the second floor seemed to be being renovated, and many places had been separated. In the Thinking Palace, after I saw the situation around me, I smiled coldly: "Mr. Mao's brain is really bad now, pick a place to eat that is being renovated!" ”

Mr. Mao is the inviter who appeared in the case, this is what Yang Minzhi told me!

This is a relatively large restaurant, and business has always been very hot, and there are many diners. However, many people who come here like to chat and eat slowly in the box, so there are dozens of large and small boxes on his second floor. The name of each box on the second floor is also very good, which makes people feel very meaningful. There is no doubt that these plots are the plots I fantasize about! I'm going to try to paint a more complete picture of the world in my mind palace with limited prompts!
