I don't want to solve the case when I'm a little policeman.

Chapter 691 Reward for triggering the system

Xu Zheng was not lying or joking, because he discovered something strange when he was looking through the chess records just now.

The annotations on the chess record seemed to be the handwriting of one person, but based on his current advanced handwriting recognition ability, it could be seen that besides Chi Jian, there was another person's handwriting on it.

In addition, the contents they marked are their respective understandings of Canqi.

There are more than 100 pages in a Canqi chess book, and each page is filled with tiny characters. It is estimated that these notes combined are more than the content.

Of course, just two people’s handwritten annotations cannot be counted as clues.

The key is that one of the two handwritings is Chi Jian's, and the other is Ni Huaiyi's.

Because the handwriting is small, the two people's handwriting seems to be slightly the same, and they are both based on running script. To outsiders, their handwriting looks like a dragon, like iron and silver hooks.

People who don’t understand handwriting identification may not be able to understand it.

The people in the Magic City Technical Detective mainly investigate the evidence of Chi Jian's crime, and naturally they will not pay attention to the annotations on the chess records.

In addition, what made Xu Zheng think this was a clue was that the text they marked was written with a pen.

Generally speaking, people like Professor Ni are accustomed to using pens because they often write some notes or important files, so that the handwriting can be retained for a longer period of time.

And handwriting like ballpoint pen can be stored for up to ten years.

Therefore, judging from the color of the handwriting written by the pen on the chess record, the writing time should not exceed half a year.

Calculated this way, if the handwriting was really written within half a year, it proves that Chi Jian and Professor Ni met frequently during this period.

But it is not as previously investigated. Chi Jian is withdrawn and rarely communicates...

In addition, half a year ago happened to be the time when Chi Jian started planning.

The main reason why Xu Zheng proposed to go back and discuss it later was that special testing equipment had to be used to identify the time of writing. After all, the naked eye and experience are not as accurate as science.

On the way, Zhang Kaiwen couldn't help but be curious and asked many times. Xu Zheng had no choice but to tell him his reasoning, "If there are handwritings within six months, it means that the two of them were at the time when Chi Jian was planning the suicide." Meet often.

So now that we have found evidence of their meeting, do we have reason and evidence to question Professor Ni? "

Zhang Wen put on his gloves and carefully read the chess records again. After reading for a long time, he came close to his nose and smelled vigorously, "Well, there is a faint smell of feet.

Eighty percent of this was written recently.

It's just the handwriting of these two people. Sorry, I can't tell the difference due to my poor eyesight. "

Xu Zheng looked sideways and said jokingly: "You're not good at this. Preliminary identification of handwriting is one of the basic skills of our criminal police. Why, it's not like you haven't written often for many years, so you haven't studied it, right?"

"Hehe." Zhang Kaiwen pushed up his glasses, "What you said is true. People rarely write nowadays. Besides, we leave handwriting identification to the Technical Investigation Department."

Ji Meiyue pulled Xu Zheng, "If we find the video of Professor Ni and the two meeting, and if you understand lip reading, can we find evidence that the two committed the crime together?"

Xu Zheng shook his head, "Lip reading cannot be counted as court evidence. If there is only video footage without time, it still does not count as evidence. However, it depends on human nature. Maybe the clues will be hidden in the next investigation point."

The Changming Municipal Bureau's large conference room was brightly lit. When Xu Zheng and the others entered, they found that only the leaders and investigators involved in the case were discussing. No one else was there. They must have gone home.

"How's it going? Did Xiao Xu find any clues?" As soon as Xu Peixin saw Xu Zheng coming in, he raised his hand to greet him and came closer to talk.

"Director Xu, are you expecting too much from me?" Naturally, Xu Zheng couldn't directly say that he had found a clue, otherwise there would be so many technical detective colleagues in Magic City who wanted to lose face, and they couldn't cause trouble for others during the Chinese New Year.

"I didn't find any clues, but I found something interesting."

As Xu Zheng approached, Xu Peixin found that he was holding an evidence bag, which seemed to be a book. His expression was a little stunned, "You really found a clue. Tell me, what's going on?"

"It's not a clue." Xu Zheng placed the evidence bag in front of Xu Peixin, explained his findings and reasoning, and finally expressed his opinion, "Although Chi Jian has committed suicide.

However, there is no conclusive evidence as to whether he was responsible for these cases.

Now that there is evidence that he and Professor Ji are in contact with each other, I suggest that we contact and question Professor Ji while looking for videos of Chi Jian and Chi Jian chatting and playing chess together.

See if you can find any useful clues. "

"I didn't expect you to find a secret in the chess record. Let me take a look." Xu Peixin took the glove handed over by the person next to him, took the chess record in his hand, and he couldn't wait to open it.

At the same time, Wan Haihong, who was next to him, also came over. Both of them were veteran criminal investigators. As soon as they opened the chess book, they turned directly to the end. When they saw the clear handwriting, they nodded at the same time.

Xu Peixin also smelled the words on the paper, and then he stuck out his tongue and licked it, and concluded, "The handwriting on this page must be within half a year. The taste is bitter and has a faint smell of smelly feet." .

It's the kind of ink smell commonly used in government agencies. "

When he said this, he took out a pile of information from his briefcase and rummaged for a long time before taking out a document, "This is a handwritten proposal written by Professor Ni when he helped us handle the case in October last year.

Judging from the handwriting, it was also written with a pen, and the handwriting was the same as on the chess record.

So Xiao Xu’s judgment is correct.

While Chi Jian was committing the crime, he also studied chess records with Professor Ni, and they were obviously in close contact with each other. This is exactly the opposite of what we found out.

I remember people from Shanghai Normal University said that the teachers and students turned against each other, and Chi Jian resigned in anger.

No more contact from now on. "

Detachment Yang nodded, "This is indeed the case. We called the relevant leaders of the school and the teachers of the School of Social Sciences remotely.

Their consensus is that teachers and students are at odds.

Just because the time was too short, we didn't investigate why they turned against each other. "

Wan Haihong looked at the time and saw that it was almost one o'clock in the morning. He asked, "How is Professor Ni's surgery going? When will it end?"

Detachment Yang shook his head and showed a troubled expression, "Still still in the emergency room, experts from Mordu's cerebrovascular, neurology, orthopedics, and rehabilitation departments have completed their consultation.

They designed a tailor-made surgical plan for Professor Ni, which greatly improved his postoperative condition.

As for asking, I think it’s better to wait a day or two before going.

At this time, especially after the operation, if he gets excited again and his blood vessels burst, that person will be doomed. "

Xu Zheng had never thought of the situation that Detachment Yang mentioned before. He still lacked experience.

Professor Ni suffered a cerebral hemorrhage, and his blood vessels are already fragile. It is estimated that the police would not be able to question him until two or three weeks after the operation.

Because if he was really behind the scenes, or participated in Chi Jian's criminal behavior, then he would definitely be excited if the police asked him or regarded him as a suspect.

When he gets excited, he will definitely disappear.

Xu Peixin and Wan Haihong had obviously thought of this a long time ago, so after discussing it just now, they decided to investigate secretly.

The police did not appear in Professor Ni's ward, but in order to prevent someone from trying to kill him, Xu Peixin sent someone to secretly protect him.

As for the investigation, everything that can be investigated will definitely be investigated. Of course, whether he has been involved in corruption or bribery will not be investigated this time.

Because the investigation is quite big and will cause criticism. After all, the professor is still in the hospital, and his home base is being raided here.

Things can be done, but if this happens, the police will have a bad reputation.

Xu Zheng realized that if the next investigation was to be carried out secretly, the efficiency would be much slower. He was not willing to spend time here during the Chinese New Year.

Then he suggested: "Xu Ju, Wan Detachment, Yang Detachment, this chess book has a lot of annotations. I think we should organize people to check what these annotations say overnight.

What if Chi Jian and the two wrote the details of the crime on the chess record? "

"What you said makes sense." Xu Peixin nodded, "In this way, you can go to the Technical Investigation Section later, wait for them to take samples, and then check the annotations written by Chi Jian overnight.

Sort it out and see if there is any useful information. "Uh...okay!" "Xu Zheng felt that he was trapped in a cocoon, but he agreed.

Xu Peixin was very satisfied with his reaction and smiled slightly, "Let Xiao Zhang and Xiao Liu play with you, and you can also discuss and learn from each other."

Zhang Kaiwen and Liu Linlin looked at each other, but they could only nod. After all, leaders don't like picky subordinates.

After the meeting, everyone else went back to rest. Wan Haihong, Zhang Yuqi and Lang Shaobai also went to the hotel to rest.

Ji Meiyue stayed and prepared to work overtime with Xu Zheng.

After the technical investigation took samples, the four of them found a small conference room. Liu Linlin made a pot of strong tea, brought some snacks, and complained: "Xu Zheng, we'd better find useful clues in these marks.

Otherwise...I want you to look good. "

Xu Zheng chuckled, "It's my fault. It's really my fault this time. I thought about giving it a try and made a suggestion, but Director Xu was not polite and just threw the job on me.

Isn't he a bit unreasonable? "

Naturally, Liu Linlin did not dare to speak ill of her leader. She rolled her eyes at him, flicked her ponytail, and brought out a scanner with an arrogant look on her face, "Bureau Xu, I trust you, so be content.

I will first use a scanner to scan the marked content and convert it into TXT format. This way we can organize it easily on the computer.

It will take about 100 minutes to complete these 10 pages. If you are sleepy, take a break first. "

The four people present had cooperated several times. They were all acquaintances and were not polite. After she finished speaking, Xu Zheng and the other three fell asleep directly on the table.

Liu Linlin saw the three of them falling asleep as soon as they said they were asleep. She shook her head silently, yawned herself, and continued working.

When she finished her work, she woke up Xu Zheng and the others, "I have generated computer text from their annotations. You can browse them all later.

You can also search for keywords directly in the Word document, such as hypnosis.

As for whether the two of them wrote down the hypnosis methods and the details of the crime in the notes, I will leave it to you to investigate slowly.

I'll take a nap first and call me in half an hour. "

Everyone in the Magic City Bureau had a busy day today. After Liu Linlin finished speaking, she untied her ponytail, went to her office to find a blanket, lay down on her desk, and fell asleep in a second.

Zhang Kaiwen took a sip of strong tea and said, "Let's do it. I didn't expect the two of them to write so many notes. It must be 70 million words, right?"
It would probably take three or four hours to read it all. "

Most of the annotations written by Chi and Jian are chess records or psychological knowledge, calculating how the opponent's next move will be, and extending from psychological theories to various real-life examples.

And they are also very good at calculating. Even for a incomplete game, they can mark it until the game is over after dozens of moves.

Sometimes they can write down two or three results for a game of residual chess.

Therefore, the marked content can be regarded as professional knowledge about Go and psychology. Zhang Zhangwen and Ji Meiyue do not know Go and only have a little knowledge about psychology, so it is really difficult to read.

But Xu Zheng is different. He understands Go and psychology. Reading these annotations is like reading the martial arts secrets of two psychology masters.

Unconsciously, he was immersed in it.

And this time, he saw six o'clock in the morning. Sure enough, studying can make people forget time. He watched it twice in the past few hours and benefited a lot.

Some of the problems that I encounter in my daily life can be solved with just a little thought. It can be said that I have made rapid progress.

It's a pity that these two people didn't write down the process of committing the crime in the annotation, but they did share how they hypnotized others.

It turns out that their hypnosis method is also quite unique. They will hypnotize people at the most relaxed moment.

For example, when both men and women are passionate, women will be obedient. Things that are usually difficult for them to agree to, as long as you work hard, you will always get an effective response.

In the same way, when a man is successful or in a state of ups and downs such as making money, winning lottery tickets, or winning gambling, it is easy for a hypnotist to seize the opportunity to perform hypnosis.

Of course, they will also use various body language to hint you before hypnosis, such as the trick on the street where they ask you to write a word and they will guess your last name.

These are all hints, one after another.

Therefore, although Chi and Jian did not write down how to commit the crime, Xu Zheng can now confidently say that he has roughly mastered their hypnosis method.

If you know the method, you can guess how they committed the crime.

It is nothing more than looking for an opportunity to hypnotize the selected suicide, and then return it to normal after getting useful information.

Then write a letter to convince the suicidal person of himself, and at the same time deepen the hypnosis.

Therefore, the initial hypnosis is just to understand the basic situation of the suicidal person, and the main purpose of a letter is to deepen the hypnosis.

Only in the end can the suicidal person be allowed to sink completely, so that they will not resist until they commit suicide.

[Ding, the system has detected that the host has learned independently and been promoted to a master psychological expert. 】

[The system rewards the host with advanced micro-expression analysis capabilities. 】

Ah…

Xu Zheng didn't expect that these five hours of repeated learning would bring unexpected surprises, and unknowingly, his psychological knowledge had improved so quickly, thanks to the annotations of Chi Jian and the others.

It also gave him micro-expression analysis. These two abilities made him even more powerful when interrogating and facing suspects.

He suddenly had a strange idea. In a sense, Chi Jian and the two were half of his teachers.

And now, he has to find evidence of the half-teacher's crime.

However, so far, although Xu Zheng read the labels on both sides, he was certain that Chi Jian must have been involved in the Changming Yangtze River Bridge suicide case.

But it is still not certain that Professor Ni is also the murderer or an accessory, or even the person behind the scenes.

Because of the mark above, Professor Ni was very cautious. He only talked about the methods and principles of hypnosis, but did not tell Chi Jian about the specific crime.

I don’t know if he hid it too deeply, or if he really hasn’t done any of these cases.

But Xu Zheng felt that even if Professor Ni was not involved in the case that Chi Jian was involved in, he must have known something about it.

"Xu Zheng, have you been studying until now?" Ji Meiyue woke up and saw Xu Zheng staring at the computer screen in a daze, with a greasy look on his face. It was obvious that he had not slept.

"I'm also impressed by you. You actually watched such boring content all night long.

You see, the three of us all fell asleep watching each other. "

Xu Zheng stood up and stretched, stretched his muscles, and looked at the time. It was 06:30 on the morning of New Year's Day. "Happy New Year, Sister Meiyue. I don't think there are any breakfast restaurants open today. Not to mention, I'm a little hungry."

Ji Meiyue took out a wet wipe and wiped her face, then handed a few more to Xu Zheng, "Go to the bathroom and wash your face. Look at you, your face is oily."

Xu Zheng smiled and followed his kindness. When he came back, Zhang Zhangwen and Liu Linlin also woke up, but they were sleepy and listless.

Seeing this, Xu Zheng smiled and said: "Go and wash your face quickly. I will take you to find evidence later."

Zhang Kaiwen came to life instantly and couldn't believe it, "There are no clues in these annotations, are there?"

Liu Linlin was combing her hair and was a little suspicious when she heard this. She had clearly asked Xu Zheng before going to bed.

If she remembered correctly, Chi Jian's annotation did not include the writing process and method at all.

"Xu Zheng, tell the truth, have you found any clues?"

Xu Zheng smiled and did not say what the clue was. "There really isn't any clue yet. Let's look for it now. How can we find it if we don't look for it?"
