Detective: Open your eyes, I am handcuffed in the interrogation room

Many people in the detachment were talking about Wang Guogui's inheritance of hundreds of millions of family assets. He had never enjoyed family affection since he was a child, so the death of the Song family might not be sad for him. At most, he would sigh. Soon forgotten.

The point is that money.

Losing a kidney in exchange for a huge amount of assets is a huge profit. With this money, Wang Guobao may be able to transplant a new one in the future.

He once relied on illegal activities to survive without a household registration, but now he has reached a height that ordinary people cannot reach in several lifetimes.

Some police officers even expressed envy in their tone. This was really pie in the sky, and luck could not stop it.

After all, it was just a case. Within a few days, everyone quickly forgot about it and focused on solving new cases.

Criminal technology training was quickly put on the agenda. Fang Songping attached great importance to this. Perhaps because he did not believe that the young Chen Yi could take charge well, he invited Geng Jianqing, an expert from the Imperial City Criminal Investigation Bureau, to provide personal guidance. The training lasted for one week and the effect was remarkable.

The Imperial City Criminal Investigation Bureau has specially established criminal investigation expert posts, which are given different titles and levels based on individual professional abilities and experience.

Geng Jianqing is a senior criminal investigation expert with short black and white hair. He is in his fifties and is a first-class police supervisor. I heard that he and Fang Songping are still old friends and have a good relationship.

Anyway, Chen Yi didn't expect that he would have to go to class after becoming a detachment leader. He slept for four out of seven days, and was distracted for two days. He spent the remaining day picking out useful things to listen to.

There is no end to learning. Chen Yi will not be arrogant enough to say that he knows everything and is invincible. Experts are experts after all. Chen Yi must accept certain experiences and unique insights with an open mind.

There is no perfect crime, only imperfect investigation. This sentence serves as the end of the training and the end of the seven days.

Chen Yi yawned and prepared to leave with He Xin.

"I'm going back to my hometown tomorrow, do you want to come with me?" Shi Xin sent out an invitation. "We don't have much fun in Ningcheng. There is only one mountain, 1,400 meters. It takes three to five hours to climb up. Try it?" The weather has been nice recently and we can see the sunrise.”

When he heard about mountain climbing, Chen Yi shook his head like a rattle: "If I don't go, I won't go. Why should I be so tired? When you climb up, take a video for me and treat it as if I climbed up too."

He Xin smiled and said: "Can it be the same? You can only feel the shock when you see the sunrise with your own eyes. When I was young, I went up there five times, but then I was busy with work and never had the chance. If you want to go, I will book it now ticket."

Everyone has different ideas. Chen Yi seemed to have little interest in mountain climbing. He looked at He Xin with admiration and said, "You have climbed five times. Are you free? If you want to watch the sunrise, take the ropeway." "

Shi Xin: "Then what am I picturing? I might as well watch the video."

Chen Yi: "You can be shocked only by your own personal experience."

"..." He Xin was speechless, "Chen Yi, how did I find out that you are so annoying when you are not investigating the case?"

Chen Yi laughed out loud, and the two of them were about to walk out of the hall side by side when they were stopped by Geng Jianqing.

Geng Jianqing was not wearing a police uniform, but his simple dress could not hide his righteousness. His firm and insightful eyes, with the determination to punish crimes, seemed to be able to see through all lies and disguises.

"What's wrong, Teacher Geng?"

After a few days, everyone called me "teacher" and I got used to it.

Geng Jianqing was not specially hired by the police department. He had a position in the Imperial City.

Deputy Director of the Criminal Investigation Bureau.

It's more friendly to call you Mr. Geng than Mr. Geng.

Being willing to come to Yangcheng at this level shows that Fang Songping has an unusual relationship with the other party.

Faced with Chen Yi's doubts, Geng Jianqing looked at him and said with a half-smile, "Commander Chen Yi, have you slept well these days?"

Chen Yi is the detachment leader of Yangcheng. Apart from Wei Jianfeng and others who are present, he has the highest position. He is also Fang Songping's future son-in-law. He is a rare young talent, so of course he pays close attention to it.

During these seven days, the other party would occasionally listen to interesting content. When encountering someone who was not interested, he would either become distracted or sleepy. Even Wei Jianfeng did not have the courage.

The person in charge of the training was the deputy bureau of the Criminal Investigation Bureau. He was not just a teacher. Chen Yi was considered a weirdo if he could fall asleep in class.

You know, leaving a bad impression on the Imperial City Police Department will inevitably have a certain impact on future promotions.

"Uh..." Chen Yi was a little embarrassed and said with a smile: "Sorry, sorry, I really couldn't hold it in. It's not that you didn't say it well, I just... couldn't hold it in."

He didn't know how to explain it.

Anyone who has been to middle school or high school has a similar experience. Although they have tried very hard to control their sleepiness, they still cannot avoid falling asleep. It is like being under anesthesia. You don’t know when you fell asleep. I don’t know how I fell asleep.

Every time he woke up in the past few days, he felt scared, worried that Geng Jianqing would cause trouble for him. Fortunately, the other party didn't care. Who would have thought that at the end of the training, he would come to settle the scores.

Beside him, seeing Geng Jianqing about to get angry, He Xin took a half-step back without any sense of loyalty, so as not to injure himself.

When Chen Yi fell asleep, he tried to wake him up, but failed, and the other party fell into a deep sleep.

Although it was training, it was also considered a classroom. Chen Yi made it clear that the class taught by Geng Jianqing was boring and unmotivated.

Geng Jianqing smiled lightly: "It seems that Captain Chen thinks that my class is of little use to you?"

Chen Yi waved his hand quickly: "No, no, I didn't mean that. Teacher Geng, just call me Chen Yi."

Geng Jianqing: "Don't be nervous, just have a casual chat. I have learned about the cases you took the lead in investigating. The serial murder case in Jiangcheng left a deep impression on me. This case lacks evidence and clues and has a long time span. How can you handle it between two people?" To catch the murderer within a month shows that he is capable."

"Criminal psychology played a very important role in this case. By analyzing criminal psychological characteristics and criminal behavior patterns, combined with a large number of interviews, you were able to make a major breakthrough in the case in a short period of time. This is your strength, right? ?”

When Chen Yigang was about to answer, Geng Jianqing's voice rang out again: "These days, whenever I talk about criminal psychology, you sleep the hardest. It shows that you are very confident in this field and have no interest in it. Come and tell me, crime Psychology also has limitations, because each person’s psychological characteristics are unique. If there are no clues, no evidence, and no inference direction, should we abandon criminal psychology and return to traditional criminal investigation methods?”

Chen Yi was decisive: "No."

Geng Jianqing: "Oh? Why?"

Chen Yi said with a smile: "The teacher just left a sentence. There is no perfect crime, only imperfect investigation. Let me borrow it. There is no psychology that cannot be analyzed, only blind spots that we can't think of. Even though everyone's psychological characteristics are unique, they His behavior must be traceable."

"Behavior is only possible if you have a psychology. The psychology of inferring behavior can never be without inference direction, even if it is a random killing in revenge for society."

Geng Jianqing didn't react much to this answer, and he couldn't tell whether he was satisfied or dissatisfied, but Chen Yi's confidence made him seem to see his past self.

"You mentioned random killings. How do you think a case like this should be solved?" he asked.

Chen Yi thought for a while and said, "There is no surveillance and no traces?"

Geng Jianqing nodded: "Yes."

Chen Yi told the truth: "There is no other way. We can only wait for the other party to continue killing people. There will not be just one random crime."

The harsh and bloody words made Geng Jianqing frown slightly, and then relaxed. He knew that what Chen Yi said was the truth. This type of case is one of the most difficult to detect. There is no interpersonal relationship and no rules. As long as the scene is cleaned up and away from probes, There is no way to start.

Chen Yi added another sentence: "Since the victim is random, he can abandon the interpersonal relationship and focus on investigating the crime method, crime location, etc. Furthermore... there is no real sense of randomness. Whether you like it or not, it is always the murderer. The psychological and behavioral factors depend on the circumstances of the case itself."

The horn can stab someone randomly and run away. It seems random and can still be analyzed, but it is more difficult and has a wider range.

Criminal investigation is a job that spans a long time and space, and there are many unsolved cases that have lasted for decades.

Geng Jianqing nodded slightly, patted Chen Yi on the shoulder, and said, "I have been catching up with Lao Fang in Yangcheng these days. You can come and talk to me when you have nothing to do."

Chen Yi agreed, but he didn't even think about going. He subconsciously stayed away from people he couldn't understand, even if they had a high position.

Very self-interested thinking, this was Chen Yi's habit in his previous life.

After walking out of the door, He Xin gloated: "Chen Yi, you're done. You will only be a detachment leader in this life."

Chen Yi retorted: "I will always be the captain of the detachment, and you will always be the deputy. No one can think better of me."

When Xin Gang wanted to say goodbye to the other party, he gave up after thinking about the Fang family. Based on this alone, Chen Yi could not stay where he was.

"You should think about going to Ningcheng again. It's hard to have a holiday."

Before leaving, Shi Xin shouted.

Chen Yi opened the door and got in the car: "Let's talk about it later."

That night, Chen Yi and Fang Shuyu talked about Ningcheng while chatting. It was a casual mention, but it aroused Fang Shuyu's interest.

"Ning Cheng? Okay, I've always wanted to come."

Chen Yi was lying on the sofa, cracking melon seeds, and said, "What is there to do in Ningcheng? How tiring is it to climb mountains?"

Fang Shuyu was clearing the dining table. The two of them were cooking at home tonight. She said, "You are always at the top during every physical training session in the team. Are you tired of climbing a mountain? Do you have other reasons?"

Chen Yi did not hide anything, and said with a sad face: "Anyway, I don't want to go to Ningcheng. I hired He Xin. If he goes to Ningcheng, he will definitely go to Ningcheng detachment to visit. He will definitely drag me along. If I go Ningcheng detachment, Xie Yunzhi must not skin me."

Xie Yunzhi, captain of the Criminal Investigation Detachment of Ningcheng City Bureau.

Fang Shuyu was happy: "Are you worried about this? Are you free?"

Chen Yi: "That's right. He Xin is a talented person from Ningcheng. I fooled him away. How much the Ningcheng detachment hated me. When I hired Lin Chen, Lao Zhou, who had a good relationship with me, stared at him. It took me five minutes."

Fang Shuyu: "You think too much."

Chen Yi insisted: "This is human nature. If you put yourself in someone else's shoes, wouldn't you be annoyed?"

Fang Shuyu thought for a while and came over with a rag in hand: "That's why you have to go over there, talk things over, and ease the relationship between Ningcheng detachment and Yangcheng detachment. They are both from Dongzhou, in case there is a case in the future. We need to help each other, and when the time comes, your people and Xie Yunzhi’s people can’t compete with each other while investigating the case, right?”

Chen Yi was silent and ignored the question.

There are soldiers as there are generals. The soldiers and generals are of the same mind. Zhuo Yun, Qin Fei and others are facing themselves, and the Ningcheng detachment is naturally facing Xie Yunzhi.

If you really encounter a case, it will definitely be awkward.

"What you said makes sense." Chen Yi finally admitted that Fang Shuyu was right.

Fang Shuyu smiled and said, "When did I invite you to come over?"

Chen Yi agreed: "Okay, I'll listen to you."

After saying that, he picked up his cell phone and dialed Shi Xin's number, saying that he would go to Ningcheng with him tomorrow.

When Xin Xing was happy, he guaranteed that he would cover all the expenses when he arrived in Ningcheng. This not only fulfilled his friendship as a landlord, but also thanked Chen Yi for his financial help.

Chen Yi did not refuse. He knew that Shi Shixin would be angry if he refused.

After confirming the itinerary, Fang Shuyu became happy and happily went to pack his luggage. Chen Yi suspected that the other party went to Ningcheng not for himself, but for fun.

"Hey, it's so difficult."

Chen Yi tuned out cartoons on TV, trying to make himself as heartless as a child.

Early the next morning, Chen Yi and Fang Shuyu drove to Ningcheng. Originally, one car was enough, but it was not particularly convenient for He Xin because he had children. After discussion, Chen Yi and Fang Shuyu decided to drive by themselves, which would give them more freedom.

The two traveling families cannot be together every day. There are always times when they travel alone. The distance brings beauty. After all, the consumption levels of both parties are not of the same order of magnitude, so embarrassment is inevitable.

Arrive at Ningcheng.

The climbing time was at ten o'clock in the evening, just in time to watch the sunrise. As expected, after He Xin took Chen Yi and Chen Yi for a stroll, in the afternoon, he took Chen Yi directly to the Ningcheng Criminal Investigation Detachment to visit his old colleagues.

After learning the news, Xie Yunzhi, who was on vacation, quickly rushed over.

It's okay to visit old colleagues, but it's not right to introduce a new boss. Xie Yunzhi, who already had a serious face, darkened his expression, which made Chen Yi quite embarrassed.

There was nothing that a drink couldn't solve. It was not recommended to drink before climbing the mountain, but Chen Yi didn't care. He pulled Xie Yunzhi and used his sharp tongue to fool him into confusion. He almost failed to surrender on the spot.

We are all our own people. The reason why we have grudges is because we have not spoken out. If we speak out, it will be fine. Xie Yunzhi also understands that people go to higher places. When Xin was the vice-captain in Ningcheng and he was the vice-captain in Yangcheng, it was completely different. the same.

Lin relied on the provincial department to see if Xin could develop better in Yangcheng. This was why he did not try his best to stop it at the beginning, so he focused all his grievances on Chen Yi.

Chen Yi saw through this while chatting and prescribed the right medicine, and the two detachments smoothed over the gap.

"Brother, you don't have to look for that boy He Xin when you come to Ningcheng from now on. He knows nothing!" Xie Yunzhi put his arms around Chen Yi's neck and started to brag after drinking.

Chen Yi: "Of course, I'm so honored to meet Xie Zhi. Why didn't we meet earlier? It's so late to meet him!"

Xie Yunzhi laughed: "It's not too late! Come on! Let's have another drink."

Everyone looked strange.

Chen Yi coughed lightly: "Thank you, it's the two brothers."

Xie Yunzhi: "Huh? Oh yes, brothers, come on!"

He Xin, who has been unable to interrupt from beginning to end, has only one thought at the moment: I can't accept it.
