Xu Zheng wasn't lying, and he wasn't joking, because he found something strange when he was flipping through the chess game just now.

The annotation on the chess game seems to be the handwriting of one person, but with his current advanced handwriting identification ability, it can be seen that in addition to Chi Jian, there is another person's handwriting on it.

And the content they marked is their own understanding of the remnant chess.

There are more than 100 pages of a book of chess games, and each page is full of small characters, and it is estimated that these annotations add up to more than the content.

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

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

Because of the small characters, the handwriting of the two seems to be slightly the same, both of which are evolved from the foundation of the calligraphy.

People who don't know how to identify handwriting really can't really understand it.

And the people of the Demon Capital Technical Investigator mainly investigated the evidence of Chi Jian's crime, so naturally they would not notice the marking of the chess game.

In addition, Xu Zheng thought that this was a clue, mainly because the text they marked was written with a pen.

Generally speaking, people like Professor Ni often use fountain pens because they often write notes or important files, so that the handwriting can be retained for a longer time.

And handwriting like a ballpoint pen can be preserved for a maximum of ten years.

Therefore, according to the color of the handwriting written by the pen on the chess game, the writing time should not exceed half a year.

In this way, if the handwriting was really written within half a year, then it proves that during this time, Chi Jian and Professor Ni often met.

And it's not like the previous investigation, Chi Jian is withdrawn and rarely communicates...

In addition, half a year ago happened to be the time when Chi Jian began to lay out.

The reason why Xu Zheng proposed to go back and forth is mainly to use special testing instruments to identify the time of handwriting, and the naked eye and experience are not as accurate as science after all.

On the way, Zhang Kaiwen couldn't help but be curious, and asked many times, but Xu Zheng had no choice, so he told him his reasoning, "If there is handwriting within six months, it means that the two of them often met when Chi Jian planned the suicide."

So if we find evidence of their meeting, is there a reason and evidence to ask Professor Ni? ”

Zhang Kaiwen put on his gloves, flipped through the chess game again, looked at it for a long time, and then leaned close to his nose and sniffed it vigorously, "Well, there is really a faint smell of feet."

Eighty percent of these were written recently.

It's just that the handwriting of these two people, I'm ashamed, forgive my clumsiness, I can't distinguish it a little. ”

Xu Zheng looked sideways and teased: "You can't do this, the preliminary identification of handwriting is one of the basic skills of our criminal police, what's the matter, it can't be that I haven't written often for many years, and I haven't studied it, right?" ”

"Hey, hey." Zhang Kaiwen pushed his glasses, "What you said is true, people rarely write now, and besides, we have handed over the handwriting identification to the Technical Investigation Department." ”

Ji Meiyue pulled Xu Zheng, "If we find the video of Professor Ni and the two of them meeting, plus you know lip language, will we be able to find evidence that the two committed the crime together?" ”

Xu Zheng shook his head, "Lip language can't be counted as evidence in court, if there is only video footage and no time, it still doesn't count as evidence, but it's man-made, maybe the clues are hidden in the next investigation point." ”

The large conference room of the Changming City Bureau was brightly lit, and when Xu Zheng and the others entered, they found that only the leaders and investigators involved in the case were discussing, and the others were not there, so they should have gone home.

"How is it, has Xiao Xu found a clue?" As soon as Xu Peixin saw Xu Zheng coming in, he raised his hand to beckon him to come closer and speak.

"Xu Ju, are you expecting too much from me?" Xu Zheng naturally can't directly say that he has found a clue, otherwise so many technical detectives in the magic capital will lose face, and they can't block others during the New Year.

"I didn't find the clue, but I found something interesting."

As Xu Zheng approached, Xu Peixin found that he was holding an evidence bag in his hand, which seemed to be a book, and his expression was a little stunned, "The boy really found a clue, tell me quickly, what's going on?" ”

"Not a clue." Xu Zheng put the evidence bag in front of Xu Peixin, told his findings and reasoning, and finally put forward his opinion, "Although Chi Jian has committed suicide.

But there is no conclusive evidence whether he did these cases or not.

There is now evidence that he and Professor Ni are in contact with each other.

I suggest that we contact Professor Ni and ask him about it on the one hand, and look for videos of Chi Jian and the two chatting and playing chess together.

See if you can find useful leads. ”

"I didn't expect you to find a mystery in the chess game, let me see it." Xu Peixin took the gloves handed over by the person next to him, took the chess game in his hand, and he couldn't wait to open it.

At the same time, Wan Haihong next to him also came over, both of them were old criminal investigators, as soon as they opened the chess game, they turned directly to the end, saw the handwriting clearly, and nodded at the same time.

Xu Peixin also sniffed the words on the paper, and then he stretched out his tongue and licked it, and concluded, "The handwriting on this page must have been within half a year, and the taste is bitter, and there is a faint smell of stinky feet."

It is the kind of ink smell that is commonly used in government agencies. ”

When he said this, he took out a stack of materials from his briefcase, and rummaged through them for a long time before he took out a document, "This is a handwritten draft of a proposal when Professor Ni helped us handle the case in October last year."

Judging from the handwriting, it is also written with a fountain pen, and the handwriting is the same as on the chess game.

So Xiao Xu's judgment was right.

During Chi Jian's crime, he also studied chess games with Professor Ni, and obviously had a close relationship, which is the opposite of what we have investigated.

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

No more contact. ”

Detachment Yang nodded, "This is indeed the case, we asked the relevant leaders of the school and the teachers of the social college remotely by phone.

Their voice is the same as that of teachers and students.

It's just that the time is so short that we haven't investigated why they turned against each other. ”

Wan Haihong looked at the time, it was almost one o'clock in the morning, and asked, "How is the operation on Professor Ni's side, and when will it end?" ”

Detachment Yang shook his head, revealing a difficult expression, "It's still in the rescue room, and experts from the cerebrovascular, neurology, orthopedics, and rehabilitation departments of Modu have finished the consultation."

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

As for the inquiry, I think it's better to wait a day or two before going.

At this time, especially after the operation, if he is excited, his blood vessels burst, and the person is finished. ”

Xu Zheng really didn't expect this situation before the Yang detachment, he still lacked experience.

Professor Ni has a cerebral hemorrhage, and his blood vessels are already fragile, so it is estimated that the police are not suitable for questioning in two or three weeks after the operation.

Because if he is really the person behind the scenes, or is involved in Chi Jian's criminal acts, then the police will inquire about him, or treat him as a suspect, then he will definitely be excited.

As soon as he was excited, the person must be gone.

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.

That is, 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 over to secretly protect him.

As for the investigation, it must be possible to check everything, of course, whether he was corrupt or not will not be investigated this time.

Because this movement is quite large, it will cause criticism, after all, the professor is still in the hospital, so he will copy people's nests here.

It can be done, but in this case, the police have a bad reputation.

Xu Zheng realized that the next investigation would be in the dark, and the efficiency would be much slower, and he didn't want to spend it here during the New Year.

He suggested: "Xu Bureau, Wan Detachment, Yang Detachment, there are a lot of annotations on this chess book, I think we still organize people to check what these annotations are written overnight."

What if Chi Jian and the others wrote the detailed rules of the crime on the chess game. ”

"You have a point." Xu Peixin nodded, "In this way, you will go to the Technical Investigation Department in a while, and after they take samples, you will check the annotations written by Chi Jian and the others overnight."

Sort it out and see if there's any dry goods. ”

"Uh... All right! Xu Zheng felt that he was cocooned and self-bound, but he also agreed.

Xu Peixin was very satisfied with his reaction, and smiled slightly, "Let Xiao Zhang and Xiao Liu accompany you to fight, 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 to pick and choose their subordinates.

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

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

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

Otherwise... Sister wants you to look good. ”

Xu Zheng smiled, "Blame me, really blame me this time, I thought about giving it a try and made a suggestion, who knew that Xu Ju was not polite, and threw this errand directly on my head."

Isn't he a little unauthentic? ”

Liu Linlin naturally didn't dare to speak ill of the leader, so she gave him a blank look, flicked her ponytail, looked arrogant, and took out a scanner, "Xu Ju trusts you, be content with you."

I'll use a scanner to scan the annotated content and convert it into TXT format, so that we can organize it on the computer.

It takes about 20 minutes for more than 100 pages, so if you are sleepy, you should rest for a while. ”

The four people present also cooperated several times, they were all acquaintances, and they were not polite, and when she finished speaking, Xu Zheng and the three of them fell asleep directly on the table.

Liu Linlin fell asleep when she saw that the three of them said they were asleep, shook her head silently, yawned to herself, and continued to work.

When she finished her work, she woke up Xu Zheng and the others, "I have generated the annotations of the two of them into computer text, you can browse them all in a while."

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

As for whether the two of them wrote down the hypnosis method and the details of the crime in the label, it will be left to you to investigate slowly.

I'll sleep for a while and call me for half an hour. ”

Here in the Demon City Bureau, everyone has been busy for a day today, Liu Linlin untied her ponytail after speaking, went to her office to find a blanket, lay on the desk, and fell asleep in a second.

Zhang Kaiwen took a sip of strong tea, "it, I didn't expect the two of them to write so many annotations, this must be six or seven hundred thousand words, right?"

It is estimated that it will take three or four hours to watch it once. ”

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

And they are also very calculating, and even a game of chess, they can write that the whole game is over after dozens of moves.

Sometimes they can write two or three results in a game of chess.

Therefore, the content marked is regarded as Go and psychology expertise, Zhang Kaiwen and Ji Meiyue don't know Go, they only have a little psychological knowledge, and it's really hard to watch.

But Xu Zheng is different, he understands Go and psychology, looking at these annotations, it seems that he is reading the martial arts secrets of two psychology masters.

Before he knew it, he was immersed.

And this time, he saw six o'clock in the morning, sure enough, learning will make people forget the time, he has watched it twice in the past few hours, and he has benefited a lot.

Some of the problems I encountered on weekdays can be solved with a little thought about it now, and it can be said that I have made rapid progress.

It's just a pity that these two people didn't write about their crime process in the label, but they shared how they hypnotized others.

It turns out that their hypnosis method is also quite unique, they will perform hypnosis at the moment when the human psyche is most relaxed.

For example, when both men and women are passionate, women will be obedient, and it is usually difficult for them to agree to things, only if you work hard, you will always get an effective response.

In the same way, when a man is successful or has a big ups and downs such as making money, winning the lottery, or winning a bet, it is easy for the hypnotist to seize the opportunity to hypnotize.

Of course, they will use all kinds of body language to hint at you before hypnosis, such as the trick on the street that asks you to write a word and he guesses your last name or something.

It's all a hint, or a set of hints to you.

Therefore, although Chi Jian and the others did not write how to commit crimes, Xu Zheng can now confidently say that they have roughly mastered their hypnosis methods.

Knowing the method, then the next thing you can guess is how they committed the crime.

It is nothing more than finding an opportunity to hypnotize the selected suicide first, get useful information, and then let it return to normal.

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

Therefore, the initial hypnosis is only to understand the basic situation of the suicide, and the main purpose of each letter is to deepen the hypnosis.

In the end, the suicide can be completely sunk, and let them commit suicide so that they will not resist.

[Ding, the system detects that the host learns independently and is promoted to a master-level psychologist.] 】

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

Scold...

Xu Zheng didn't expect that there would be an unexpected joy in these five hours of repeated study, and he unknowingly made such rapid progress in his psychological knowledge, thanks to the annotation of Chi Jian and the others.

It also gave him access to micro-expression analysis, which made him even more powerful when interrogating and facing suspects.

He suddenly had a strange thought, in a sense, Chi Jian and the others were half of his teachers.

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

It's just that, so far, although Xu Zheng has looked at the marks on both sides, it is certain that Chi Jian must have committed the suicide case of the Changming Yangtze River Bridge.

But it is still uncertain that Professor Ni is also a murderer or an accomplice, or even a person behind the scenes.

Because of the label, Professor Ni was very cautious, and only talked about the hypnosis method and principle, but did not tell Chi Jian about the specific crime.

I don't know if he hid it too deeply, or if he really didn't do these cases.

But Xu Zheng felt that even if Professor Ni did not participate in the case that Chi Jian did, he must know a little bit 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 an oily look on his face, obviously not sleeping.

"I also served you, such a boring content, you actually watched it all night.

Look at the three of us, we're all asleep watching it. ”

Xu Zheng stood up and stretched his waist, stretched his muscles, looked at the time, and at half past six in the morning on the first day of the Lunar New Year, "Happy New Year, Sister Meiyue, it is estimated that there is no breakfast shop open outside today, not to mention, I'm a little hungry." ”

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

Xu Zheng smiled, and when he came back, Zhang Kaiwen and Liu Linlin also woke up, but the two of them were sleepy and listless.

Seeing this, Xu Zheng smiled and said, "Hurry up and wash your face, and I'll take you to find evidence in a while." ”

Zhang Kaiwen came to life in an instant, and couldn't believe it, "There are no clues in these labels, right?" ”

Liu Linlin was combing her hair, and she was a little suspicious when she heard the words, before going to bed, she obviously asked Xu Zheng.

If she remembers correctly, the annotation of Chi Jian and the others did not have the process and method of writing the case at all.

"Xu Zheng, tell you the truth, did you find any clues?"

Xu Zheng smiled, and didn't say what the clue was, "There is really no clue at present, let's look for it now, how can we have it if we don't look for it?" ”
