Before Gu Chen entered the living room, he had actually found these blank papers, but there was no handwriting on them.

But now that I think about it, Liu Geng's mother has a severe visual impairment, that is, she can't write at all.

Doesn't it seem strange that she left so much blank paper in the living room in this situation?

An old lady was poisoned to death on the sofa, but no source of poison could be found at the scene, this abnormal situation is really hard to believe,

On one side is Officer Wang and Lu Weiwei's Cui Ci, and on the other side is Liu Terrier's send-off, Gu Chen looked at an abnormal white paper in his hand, or folded it and put it in his pocket.

At this point, it's also time to eat.

Officer Wang drove Gu Chen and Lu Weiwei to a small noodle restaurant nearby.

There aren't many people who come to eat noodles at this point, or it's completely past lunchtime.

But pasta has an advantage that ordinary foods don't have, that is, it can be prepared in a variety of combinations and is extremely fast.

Usually, the hot water in the small shop is insulated, and it can be boiled when the stove is heated.

The handmade noodles are packed in a plastic bag and put directly into the pot.

As for the combination of seasonings, there are no less than 20 kinds of spices in the shop, so you can just pick up the handmade noodles and mix the selected dishes freely......

"Hiss!" Lu Weiwei took a sip into her mouth and let out a "tsk" exclamation: "Lao Wang, I know a secret." ”

"What's the secret?" said Officer Wang, still pouring vinegar.

Lu Weiwei raised her head and said, "That is, under the condition of your extreme hunger, no matter what food you eat, it is very fragrant." ”

Then Lu Weiwei pointed to this bowl of noodles and said: "You see that this bowl of noodles is long and wide, I usually don't like it at all, but it tastes very good today." ”

"So...... That's your secret?"

Officer Wang thought that there was a major miracle, and he looked up and waited for her for a long time, but it turned out to be this, and couldn't help but shake his head and sigh: "That's okay, next time you have a treat, postpone it for an hour or two, and when you are hungry, you can be moved to tears when we go eat a pancake fruit." ”

"Wang, you have changed. Lu Weiwei stared at him with disdain, then turned her head and asked Gu Chen, "Senior Brother Gu, do you think Lao Wang has changed?"

Gu Chen nodded while looking at the blank piece of paper.

Nodding was a conditioned reflex, but Gu Chen didn't hear what Lu Weiwei was saying just now.

For example, when a person is on the phone, no matter what you hand him, he will answer it, and then look at you with a confused face, and he doesn't know what he is doing.

"Huh, what are you doing with a blank piece of paper in your hand?" Officer Wang also "hissed", sucked the wide noodles into his mouth, and couldn't help but burp.

"This was brought out of Liu Geng's house. Gu Chen also showed it to Officer Wang.

"Liu Geng's family brought it out?" Officer Wang was also stunned, stretched out his hand to take the white paper, and then asked, "Eh, why are there some small holes on this?"

"I don't know. Gu Chen also shook his head, picked up his noodles and took a sip of soup.

In fact, Gu Chen couldn't say it, he just felt that these blank papers shouldn't be in the living room.

Although I also thought that these might be clues, I didn't think about any effect.

"Then don't think nonsense, let's wait for the results of Forensic Medicine Liu to come out. "Officer Wang is not in a hurry.

He knows the truth that he can't eat hot tofu in a hurry.

The clues collected are limited, and Gu Chen has not fully figured out why the old lady was suddenly poisoned, and he doesn't know if there is a problem with the three so-called good aunts.

If someone deliberately poisoned them, what was the motive?

Can a blind old lady still expect to benefit from her? This is simply unrealistic.

In Gu Chen's opinion, a family like Liu Geng really can't see any hope.

Could it be that it was because Liu Geng had a holiday with someone outside, and the other party took revenge on his family?

But in the chat with his old classmate Zhuang Xiaohai, Gu Chen learned that this Liu Geng was quite well connected near Xijie Primary School.

It's also because of the long time that he has been operating here, so if he wants to make a feud, it won't be enough.

"Senior Brother Gu, listen to Lao Wang, your police card is about to come down. Seeing Gu Chen in a stupid daze, as if he was not very happy, Lu Weiwei beside him hurriedly changed the topic.

"yes? That's good. Gu Chen didn't look excited.

Officer Wang said with a smile: "Originally, your batch of probationary police officers meant that you would be regularized after a year, but some of you have performed well, and there are many outstanding talents in the city, so the bureau decided to help you become regular in advance, and it may not be long before there will be a notice." ”

"Senior Brother Gu, do a good job, I'm optimistic about you. Lu Weiwei seemed to be happier than Gu Chen.

"You know, Lu Weiwei's class is a full year, and your batch is lucky. ”

Speaking of this, Officer Wang "hissed", then picked up a large bowl and poured the noodle soup into his stomach, and then said to Guan Zi: "I have another piece of gossip, I don't know if you are interested in hearing it."

"Lao Wang, you are selling Guanzi again, say it quickly. Lu Weiwei was a little impatient.

Seeing that Gu Chen did not react, Officer Wang asked again: "Alas, Gu Chen, do you want to know? If you want to know, I will tell you." ”

Gu Chen let out an "oh", and then said, "Then you can say it." ”

"Why do you feel that my pass is very cheap?" Officer Wang was also puzzled, but still said: "I heard from friends in the bureau that our Furong Police Station has been listed as the reference list of the first batch of new sub-bureaus, and I heard that four to five new police stations will be set up below, and the level of the police station will be discussed again." ”

"Really?" Lu Weiwei was stunned at the time: "Then aren't we Zhao Suo going to die of laughter?"

"Yes, this is Zhao Suo's life's work, then he should be quite happy. Gu Chen was also attracted by this topic.

As a result, Officer Wang waved his hand and said, "Our Zhao is not happy." ”

"Huh, this is not happy?" Lu Weiwei was also quite surprised, and asked, "Why is this?"

"The precinct has the distress of the sub-bureau. Officer Wang picked up a glass of water beside him and poured it into his mouth, and then said: "In the past, our Zhao Institute dreamed of upgrading the Furong Police Station to the Furong Branch, after all, our Furong Police Station is the structure of the sub-bureau, but there is no signboard of the sub-bureau. ”

"If it weren't for the increase in the concentration of floating population in Jiangnan City in the past seven or eight years, and the increase in institutions was already imminent, we might not have this opportunity. ”

"Then since it has been upgraded to the Furong Branch, isn't Zhao Suo the director of the Branch? Wouldn't we, the backbone forces, also have to be upgraded by one level?" Lu Weiwei seemed to be quite interested in this kind of good thing.

"Herein lies the problem. Officer Wang stretched out his index finger and said, "Once it is set up as the Furong Branch, we will definitely add four to five police stations, and at that time, our criminal investigation team, as well as the backbone of other departments, will all have to be dispersed and assigned to various police stations, and together with the personnel assigned by the city bureau, they will form the backbone of the new police station." ”

"Ah, do you want to separate?" Lu Weiwei was not so happy when she heard about the separation.

"If this is the case, then Zhao Suo will indeed be a little reluctant, after all, his subordinates are all brought out by him. Gu Chen also answered.

"That's right. Officer Wang also nodded and said, "Especially our three criminal investigation teams may have to be sent to different new police stations to form the core force of the major new police stations, and the previous personnel structure may also be redistributed." ”

"No wonder Zhao Suo let us on the honor list, and also gave our three groups a desperate increase in manpower, it turns out that Zhao Suo has been planning for a long time? In this way, maybe two-thirds of the members of the three groups may be sent abroad. Gu Chen also saw the problem.

In fact, while the three groups had a large increase in manpower, Gu Chen had a hunch that maybe Zhao Guozhi would have to build another criminal investigation team.

Now it seems that the criminal investigation force is being set up for the new police station, and the existing personnel are being reserved and trained.

"As long as the three of us can be together, it doesn't matter where he goes. Lu Weiwei also didn't care: "Anyway, where Senior Brother Gu goes, I'll go." ”

"Eh, this is a mountain, or not. Officer Wang also hurriedly complained: "How to arrange it above is a decision from above, we just need to absolutely obey the order." ”

I feel that Lu Weiwei is pulling the mountain, and there is even a posture of not marrying Gu Chen.

Officer Wang also saw through it and didn't say anything.

Lu Weiwei was a little unhappy, or a little uncomfortable.

Sure enough, Zhao Guozhi's worries are also his own worries.

"Have you finished eating? After eating, let's go to the technical department of the city bureau and ask forensic doctor Liu for results." Officer Wang was also about to take out his mobile phone.

Gu Chen took the first step to get up and said, "If I come this time, I can't always let Senior Brother Wang pay." ”

Then Gu Chen walked to the counter and paid for the face with his mobile phone.

......

......

Twenty minutes later.

The three of them drove to the technical section of the city bureau.

Why do you often come here? Because in the process of dealing with Forensic Doctor Liu, the three of them knew a universal pattern.

That is, the more diligent you run, the easier it is to get the results faster.

Forensic work is complex and tedious, and can be a day long to deal with a variety of tests from across the city.

So crying children have milk to drink.

If you simply wait, it may take longer.

Under normal circumstances, staying in the technical department, even if the technical department is inspecting other operations, for the sake of face, it will try to give priority to your test report in the queue.

However, in the technical department, not all forensic doctors can speak as well as Forensic Doctor Liu.

Other forensic doctors, as usual, are step-by-step, and they do what they do.

If there is a new test after work, if it is not particularly important, it is usually not overtime, but the relevant test is not started until the next day after work.

But Forensic Liu is different, in terms of workaholic characteristics, he is a little similar to Gu Chen.

It's not uncommon to work overtime late into the night.

Therefore, the assistant under Forensic Doctor Liu is also full of complaints.

And the police officers who often come to Liu's office to line up for tea are often more than other forensic teams.

Without him, because Forensic Doctor Liu is a workaholic.

When Gu Chen, Officer Wang, and Lu Weiwei came to the technical department, there were still some policemen handling the case at the door of Forensic Doctor Liu's office.

Everyone stood in the hallway of the door, chatting about the latest trivialities.

Officer Wang was the first to stop, frowned, and said, "It seems that Forensic Doctor Liu is very busy today." ”

"Lao Wang, what do you say, we will listen to you. Lu Weiwei said.

"Let's go and see. Officer Wang didn't care too much about it, and strode over directly.

"Eh, Lao Wang?" a third-level police inspector who was chatting couldn't help but say to Officer Wang.

"Lao Zhao, Lao Guan, Lao He, you are also here?"

"It's been a long time since I've seen your old king, I heard that you've been doing well lately?"

"Wherever you are, it's all for the people. ”

"The salted fish king turned over, and the tone of his voice was different. ”

"Hey, hey, hey!"

A few people quickly chatted together......

While chatting with a few people, Officer Wang put his hand on his back and beckoned Gu Chen and Lu Weiwei to go in first.

At this moment, Forensic Doctor Liu was writing materials on his desk, and when he saw Gu Chen and Lu Weiwei walking up, he also knew the intention of the two.

"You guys came here so soon, my test report hasn't been written yet. Forensic Doctor Liu also said slowly.

"Who doesn't know that you Forensic Doctor Liu pays the most attention to work efficiency, we just need to know the key clues, and you can write the rest slowly, not in a hurry. Lu Weiwei is also well aware of Forensic Liu's work sequence.

After the test is completed, he must first sort out the information and write the test results into an easy-to-understand analysis report.

And it is exactly this work that Forensic Doctor Liu is doing at the moment.

"What do you want to know?" asked Forensic Doctor Liu.

"Time of death, toxic substances. Gu Chen said.

Forensic Doctor Liu lifted his glasses, handed one of the pages of the information sheet to Gu Chen's hand, and said, "The deceased may have eaten poisonous lotus seed soup before his death, and the time of death was this morning, probably ...... Between nine and ten o'clock. ”

"The time of death is in the morning?" Gu Chen was also quite surprised, and hurriedly checked the results carefully.

"But we didn't find any food like lotus seed soup in the deceased's house, which we had looked for many times. Lu Weiwei has a special say in this.

Because the shooting records of the whole scene were completed by herself, all the rooms, all the places where toxic substances may appear, Lu Weiwei has carefully checked.

Even under the bed, under the cupboard, and even around the bungalow, she has checked.

The so-called lotus seed soup does not exist at all.

"Then I don't know, these are your things, and I have already checked for you, the deceased did take lotus seed soup before his death. ”

Forensic doctor Liu took out another analysis report that had not yet been written, and said: "This is my preliminary extraction of some components from the abdominal cavity of the deceased, and the test results show that they are toxic substances, which are more severe and may lead to immediate death, and the specific components are still being analyzed." ”

"So, Liu Geng's mother was poisoned with lotus seed soup between nine and ten o'clock?" Gu Chen looked at Lu Weiwei beside him.

"Could it be those three kind-hearted aunts?" Lu Weiwei also questioned, saying: "After all, their statements are all connected, in case what they say is a collusion, it will be a big trouble." ”

"Senior Sister Lu, what you said is right, I don't know the specific reason now, maybe these three people are also very suspicious. ”

Gu Chen also lowered his head and pondered for a few seconds, and suddenly remembered the drill bit he had found from the old lady before, and the white paper with holes, and immediately quickly took it out of his nine small pieces.

"By the way, Forensic Doctor Liu, if they are blind and want to communicate with people in letters, how should they operate?" Gu Chen asked.

Forensic Doctor Liu was stunned for a moment, and then said slowly: "I've heard someone say before that the communication between blind people seems to have a special kind of Braille. ”

"Braille?" When Gu Chen heard this, his eyes suddenly lit up, and he hurriedly put the empty paper and the drill bit on Forensic Liu's desk.

"Who are you?" Forensic Doctor Liu was also stunned.

Gu Chen stretched out his hand: "Do you want to see if this is blind?"

Forensic Doctor Liu helped his eyes, took the white paper in his hand, couldn't help frowning, and asked Gu Chen, "Where did you get this?"

"The deceased's living room was found, and there were doubts about these small holes, and when the deceased was taken to the hospital, he used to hold the drill tightly in his hand, and I thought it was the old lady who had a heart attack while doing needlework. ”

Gu Chen informed Forensic Doctor Liu of his situation in the hospital and the deceased's home.

"It seems that your speculation is completely correct. Forensic Doctor Liu suddenly turned on the computer and looked up some files in a database.

Soon, he clicked on one of them, and quickly stood up, walking towards the vault in the compartment.

It didn't take long for Forensic Doctor Liu to take out an old book and come to Gu Chen.

"What is this?" Gu Chen asked.

"Braille Beginner Tutorial. Forensic doctor Liu said.

Lu Weiwei was shocked: "Forensic Doctor Liu, why do you have everything here?

"Not really. Forensic Doctor Liu also waved his hand and said, "More than ten years ago, a blind man came to report the case, and later left the book in the business hall. ”

"My colleagues thought that they would put it in a drawer and wait for the blind man to come and pick it up, but they didn't wait, and then they threw the book to me and asked me to put it in the reference room. ”

"I originally thought that I wouldn't need it for the rest of my life, but now it seems that it will help you Gu Chen a little. ”

Gu Chen didn't say anything, took the "Elementary Braille Tutorial" in Forensic Doctor Liu's hand, quickly found a seat and sat down first, and then began to quickly flip through it.

Lu Weiwei also hurriedly ran over.

"Braille is composed of tactile text, which is made up of different combinations of bumps on the paper through a braille board, a braille machine, etc. ”

"Braille for each square of Braille consists of six dots, plus blank space, for a total of 64 variations. ”

"Braille can also represent mathematical and musical symbols. ”

"The inventor Braille is characterized by the ability to read and write at the same time. ”

Gu Chen silently read the theory on the "Elementary Course of Braille", and at the same time, according to the drilling on the paper, he began to quickly flip through and find it.

Lu Weiwei was also stunned, and said in a daze: "Senior Brother Gu, do you think the small holes on these papers are really Braille?"

"If there is no other better explanation, I would rather believe that this is true. Gu Chen also nodded and said, "Old lady...... She must have wanted to tell us the so-called truth. ”
