Su Cheng was very relaxed and in a good mood, saying, "I am not asking you to compliment me. I think I am also very powerful, and I still think Hua Feiyu is innocent, but why can't I solve this case with such a powerful person? I suddenly remembered a word called "Return to the Nature, Qi Ming, you are a patrolman, and you have never been in contact with real criminal investigation work. Bai Xue, you are in the learning stage now. I know that you have your own opinions on many cases, but you dare not say it. Hua Feiyu's case, you think you are an idol, and I think it's a very powerful person. There is a very likely possibility that I am bound and the truth is in front of me."

Bai Xue and Qi Ming expressed that they didn't understand very well.

"Taking the novel The Three Kingdoms as an example, Zhuge Liang and Sima Yi are both old foxes. Zhuge Liang forced Sima Yi a little and scared Sima Yi away because Zhuge Liang understood Sima Yi. When we handle the case, it is difficult to fully understand a suspect, his spirit and his behavior. Suppose the Kongcheng plan is a fool to replace Sima Yi. When you look at the Kongcheng, you will rush in without saying a word, which can break the Kongcheng plan. I think I am in Hua Feiyu... No, in the past few months, I have always felt that because of long-term contact with various brain-intensive cases, my thinking pattern has been imprisoned. This time I will find you two chicks to solve this case."

Su Cheng said: "The premise is that Hua Feiyu is not a prisoner. How can we prove this? Can we prove that Zhang San may have been killed by an outsider? Did you ask you to bring your computer with you?"

"Take it." The two of them took out their bags as if they were doing their homework.

Su Cheng said: "Contact xxx of the physical evidence group, he will send you the process of restoring the site today, the debate between us, and the video of a one-hour duration. As for other information, you can also contact the people in the physical evidence group, and I need you to find the answer. Remember, this criminal is not a transnational old bird, Bai Xue, go there, Qiming, you are not allowed to contact each other, start doing the questions."

The two started very well. Su Cheng took Bai Xue's cell phone and called: "Madam, I'm having fun in the xx nightclub. Should I come and catch the current situation... Damn, Zhou Duan treats my wife as a beast and hasn't had a rest for a few days... Sorry, Xuanzi, I was wrong... It's... No problem... No problem..."

So bored, Su Cheng moved to the nightclub lobby. Nightclubs were divided into many small departments, including noisy Di Bar, quiet water bar, KTV, performance venue, etc. Su Cheng went to the water bar, and when he sat on the bar, he asked for a bottle of mineral water, and listened quietly to music. Usually, the water bar made the girl Bidi Bar more elegant, and Di Bar just looked at the face. The two of them put their butts together and twisted their butts, and when they met, they drank a drink, and then saw the reason why each other came to the nightclub. In this era of fire, all they needed was a platform. Now, because of the popularity of social software, nightclub business was not easy to do.

The water bar is usually an exchange between prey and hunter. If a girl sits alone, she will ask the waiter to give her a drink. If the girl is interesting, she will raise her glass. Then the gentleman will find an excuse to sit down together and talk to each other. Even if the girl is waiting for someone or other reasons, she can still talk, and both parties will find more things except the outside.

Such a handsome guy sits at the bar for twenty minutes, why is there only the bar waiter who serves mineral water for himself? The reason is that he ordered mineral water, which is very boring at first glance. It depends on the connotation. Who can see your connotation when you have time?

The wine sip is very talkative and good at observing words and expressions. He knows that you need to chat, but still wants to be alone. Su Cheng chatted with him: "So there is a girl named Ma Ziye here. Do you know him?"

"Oh, I know." The wine guru wiped the cup and polluted the cup twice: "I didn't do it a year ago. It is said that he inherited the overseas heritage and went there with ease."

Su Cheng asked: "Apart from me, is there anyone who is stranger to ask you about her?"

"recent?"

“A year ago.”

The wine snorkel smiled and said, "Police Officer, you're kidding. I have to chat with many people every day. How could I remember what happened a year ago?"

Su Cheng said: "I know you have goods in the cabinet. Someone has been waiting for me to leave the bar. If you guess, it should be someone from Di Bar asking for something... I don't care about shaking my head, everyone gives in to each other, be kind, okay?"

The wine guru is in his thirties and has never been nervous about seeing the world: "Okay."

Su Cheng took Bai Xue's cell phone, put some photos together just now, and handed them to the wine steward: "Who has asked?"

"He." refers to Liu Mo.

"He... seems to have been here a few years ago, it's very special. I can smell that he is a policeman or a person from the relevant department, so pay more attention and call Zhiye in advance."

From the side, Su Cheng looked at it, it was the Supreme People's Procuratorate.

The wine drinker looked at it for a while and returned the phone to Su Cheng: "There is another man in his thirties, and there is no photo on it."

Su Cheng asked: "A man in his thirties is going to come late or early than if you recognize the first man?"

"The first man was just less than three minutes away. The man in his thirties gave me a few hundred dollars and asked the man what he asked."

"Oh?" Su Cheng was surprised. Liu Mo was actually followed. This is not very scientific. First of all, Liu Mo is very capable. He must be a good player if he is not discovered. Someone can do it in z7. Secondly, why is he stalking Liu Mo? Liu Mo just asked Ma Ziye about Ma Ziye's situation at that time. Before he had contacted Ma Ziye, he shouldn't have been discovered at this time, and he sent out the stalker so quickly. That is to say, Liu Mo had been suspected before.

But there are conflicts. If they suspect Liu Mo's investigation direction, for example, Liu Mo inquired about the murder of the Supreme People's Procuratorate and retrieved certain information and asked Liu Mo to find Ma Ziye, then they would know the purpose of Liu Mo coming to the bar and would not send anyone to ask the drinker again. It is inferred that someone was following Liu Mo, but it was not because of Ma Ziye.

Su Cheng suddenly smiled sinisterly, then took five hundred yuan and put it on the table: "I have never asked."

"Don't worry, I dare not offend you." The wine gushing smiled and watched Su Cheng return to the private room. He threw the mineral water bottle into the trash can as if nothing had happened, and wiping the countertop, and put five hundred yuan in his pocket. After seventeen years in this industry, people in the martial arts world have seen too many people, and it is best not to provoke people like Su Cheng.

A girl came to the bar and looked at Su Cheng's back: "Who? I can't tell anyone who drinks mineral water, but it's very generous to take action. Which rich second generation?"

The winemaker continued to wipe the cup and said, "Marilyn, let's forget about this...How about that last time I hooked up?"

"I'm paralyzed and treated me as a woman and gave me two thousand yuan. Damn, do I care about two thousand yuan?"

"Why do you want to catch a rich man and have to change the place. You have been in a bar for half a year and have seen a lot. Who would meet in a nightclub and get married without getting divorced soon? Come here to relax and relieve stress, and make an appointment when you meet a suitable partner. Feelings are very expensive and no one is as casual as anyone."

...

Su Cheng returned to the private room and clapped his hands: "Okay, sort out the case."

Bai Xue had contacted Hua Feiyu's case on one side and discussed it with Qi Ming for a while. Bai Xue said: "The biggest doubt in this case is why the kitchen knife goes to the bedroom, and from the bedroom to the kitchen. Consultant, you have proposed the knife from the bedroom to the kitchen, mainly how the knife goes from the kitchen to the bedroom... I initially guessed that it would be Zhang San who carried the knife with him after cutting the meat."

"Then what?"

Bai Xue said: "Then I think it's unlikely. It's obvious that Zhang San was stabbed shortly after entering the door. Zhang San wanted to hide the knife. The murderer held the knife. According to Zhang San's clothes at that time, I don't think the murderer easily got the knife and was not discovered by Zhang San."

Su Cheng said: "I didn't expect Zhang Sanzang to go to the bedroom with a knife. This is a good thing, but as you said, the possibility is not high. There is no basic purpose. What about Qiming?"

Qi Ming said: "I noticed that if there is a murderer in the neighborhood, and you use the method of consulting you to send the knife back to the kitchen and mix into the neighborhood, then the murderer is probably Li Si. Judging from the professions and skills of several neighbors, he is a surgeon. A fatal blow means that the murderer is very serious in killing, which means that he will kill people. In this mentality, most people will stab the knife continuously, but the murderer does not, which means that he knows the consequences of this knife very well."

Su Cheng nodded: "What about?"

Qi Ming said: "As a surgeon, boldness and carefulness are the most basic requirements. As a neighbor, Li Si may know that Zhang San has the habit of putting the key under the foot pad. In my imagination, Li Si had the intention to kill and sneaked into the Zhang San family, but Li Si did not expect that Zhang San was not alone. After killing Zhang San, in the next few minutes, Li Si had enough time to consider getting out."

Su Cheng said: "Continue."

Qi Ming looked at Su Cheng and smiled bitterly: "I don't know how to continue."

Su Cheng stood up and patted Qi Ming on the shoulder, touched Bai Xue's head, and said, "I already know the truth, but I need to confirm it first. It turns out that it is the most rare thing to be uncensored."

Bai Xue looked up: "Consultant, what does it mean?"

Su Cheng picked up his mineral water bottle and said, "I turned out to be aware of the world from this bottle. No matter how big my imagination is, I can only see the world of the bottle. If you give me a beer can, I will naturally see the world of the beer can. My biggest mistake in this case is that I pay too much attention to the murderer's method of killing and the contradiction of moving the knife. Okay, I will pay the bill, you drink more, don't drive."

Contradiction theory is the basic principle of solving cases and the core of solving cases. When encountering a case, first look for conflicts from the confession and record, and you will naturally find the answer. Just like a lie, in order to make up a lie, he will tell more and more lies. After solving one conflict after another, the clues will become clearer.

However, Su Cheng once raised doubts about the theory of contradiction. If he is too focused on details and contradictions rather than looking at the case in a macro way, will the view lead to too one-sided? Big Pineapple affirmed Su Cheng's doubts. Big Pineapple told Su Cheng to study the Sherlock Holmes deduction method seriously and you will find that there are also misunderstandings in artificial use. Big Pineapple told Su Cheng that contradiction theory is a weapon, but you cannot have only this weapon.

Over the past six months, Su Cheng has really solved many cases by relying on the theory of contradiction, but because of victory, it is too limited to the theory of contradiction. In the past, Su Cheng only investigated the contradictions, and the other clues were investigated by Zuo Luo and others. From the Wu Nin case to the present, Su Cheng always felt that he lacked something. Now he understood that he regarded the theory of contradiction as his only weapon. Sometimes he could not solve the case, but also blinded his eyes.

...

Li Si was invited to the interrogation room. Of course, it was not an invitation to the interrogation room. To be precise, it was the criminal detention notice that Li Si was invited. Fang Ling and the people from the physical evidence team were searching Li Si's home and work location.

Su Cheng and Zuo Luo were the judges, and Su Cheng asked: "Li Si, how is your relationship with Zhang San?"

"It's OK, neighbor, look down and see you."

Su Cheng asked: "Do you often visit each other?"

"There is basically no. Nowadays, many people don't like visiting neighbors, and I don't like it either. I always feel that others are disturbing your life."

Su Cheng asked: "Have you been to Zhangsan's family? In the past few months?"

"Maybe there are, occasionally going upstairs, saying hello, and sometimes going to the neighbors' house to contact each other for a little. After all, neighbors still need to know each other, such as owners, property, community environment, etc.."

Su Cheng asked again: "Then have you been to Zhang San's bedroom?"

Li Si shook his head: "I am not a gay man, how could I go to someone else's bedroom?"

Su Cheng smiled: "Full of confidence. As a surgeon, you plan and have plenty of time. You believe in yourself."

Li Si said: "I don't know what you are talking about."

"This case was very simple, and logically, it is basically impossible to prove that when the case occurred, Zhang Sanjia had a third party in addition to Hua Feiyu and Zhang San. Although I have tried hard, I found that the position of the murder weapon was transferred too strangely. However, there was a turning point in this case, and the turning point was Hua Feiyu. Hua Feiyu was very tough. Assuming that Hua Feiyu changed his confession and the lawyer and the prosecutor had a chance to win the case. If she changed it and fought back because of the drug, the case would basically end, at least for me. But her tough attitude made me never believe that she was a criminal. If she was not a criminal, there would definitely be a third party in the room. I must prove how the bone-cutting knife went from the kitchen to the bedroom, and how to go from the bedroom to the kitchen."

Su Cheng said: "I have solved some of them. The murderer hid in Zhang San's bedroom, killing people and hiding on one side. Hua Feiyu was frightened when he saw the murder scene and grabbed the door. The murderer put the murderer back into the kitchen. When the neighbors rushed in, the murderer smuggled into the neighbors. The murderer knew people very well and knew that at the time, the neighbors were shocked and the pace was fast, so it was difficult to remember the details. In addition, after discussing the case with the neighbors, the murderer used some words to hint that he entered Zhang San's room with them, so the neighbors naturally made perjury inadvertently."

Li Si thought for a while: "Does the police officer think I killed Zhang San?"

"Yes, I think you hid in Zhang San's room and killed Zhang San."

Li Si asked with a smile: "Mr. Police Officer, how did I get the knife in the kitchen to kill Zhang San?"

Su Cheng asked back: "How do you know that it was the kitchen knife that killed Zhang San?"
