"Officer Juan Busettic, did this man contribute anything? he designed the fingerprint system?" asked Officer Wang.

Gu Chen nodded, then wrote the name of Police Officer Juan Busettich in his notebook, and then smiled: "That's right, because he is convinced that fingerprints can be used to identify criminals, and he has invested in the design of the classification system." ”

In 1904, he published a book on the subject, and the system is still used in much of South America. ”

"And Argentina was the first country to use fingerprints to solve criminal cases. ”

"That's the point, you have to circle it. Nie Xiaoyu was fascinated when she heard it, she quickly pulled the notebook in Gu Chen's hand, continued to record Gu Chen's words, and then asked, "Brother Gu Chen, is there a specific case?"

"Yes!" Gu Chen raised his head, thought about it carefully, and then said: "For example, on June 18, 1892, there was a man named Francesca Roja, one of her children was killed, but she alleged that the murderer was a man named Velázquez. ”

"Uh, Brother Gu Chen, do you even remember the date?Can you remember the names of people so clearly?" Nie Xiaoyu had never seen Gu Chen's super memory before, and when Gu Chen said this, the whole person was stunned, and he couldn't react for a long time.

However, compared to Nie Xiaoyu and other melon-eating colleagues around them, Lu Weiwei and Officer Wang seemed much more immune.

Lu Weiwei directly smiled and explained: "This is not strange, if you read books and take notes every day, you can also be like Senior Brother Gu." ”

"That's right, I've seen it before. It was also to calm Nie Xiaoyu's sluggish expression, Gu Chen found an excuse, and then said:

"The man Francisca Roja was just talking about, and one of her children was killed, but she alleged that the murderer was a man named Velázquez. ”

However, Alvarez, a police investigator trained by Busettich at the time, discovered that Francesca Roja had a lover who had offered to marry her if she had no children. ”

So in the end, he found a fingerprint that matched the thumb of Francesca Roja's right hand at the scene, and finally made her bow down and confess, which is the power of fingerprints to solve the case. ”

"I didn't ...... That's right. Nie Xiaoyu was also stunned, and said weakly: "So, if there was no fingerprint system design at that time, the police would not have been able to confirm that Francesca Roja was the real murderer of the child, which is really powerful." ”

"If in that era, when fingerprint solving was not yet popular, it would have been able to master this mature set of technology, wouldn't that mean that it would be a cool point. ”

Thinking of this, Nie Xiaoyu's whole heart was full of joy, and he felt that his material was available again, so he quickly recorded it again, and then asked Gu Chen: "Brother Gu Chen, before that era, were there any other forensic identification techniques?"

Gu Chen thought for a while and said, "Then you can try ballistics." ”

"Bullet ...... Ballistics?" Everyone echoed in unison, and everyone's eyes were on Gu Chen.

"That's right. Gu Chen just pushed away the plate, stood up and said: "Because ballistics, in fact, it is also called gun inspection, at that time, Harold Peterson, in one of his books, mentioned that the Germanic emperor, Maximilian, drew rifling for firearms from 1493 to 1508. ”

This book became one of the earliest documents on the subject. ”

However, for a long time, it was not confirmed that this rifling could be used to compare the body of the projectile with the firearm. ”

It wasn't until the late 19th century that it gained final recognition. ”

In the early 20th century, Calvin Goddard devised a complete system. ”

"Being able to compare different warheads under a microscope to determine whether the two sides fired with the same weapon is a technique that is still used today and is also used by police in various countries. ”

"So, the real science of forensic forensics didn't come around until the late 20th century, and most of the techniques came around in the 20th century. ”

Gu Chen looked at Nie Xiaoyu, who was immersed in taking notes, and then said, "Since what I said, every technology is within the time range of your story, and there is already a possibility of existence. ”

"Then the protagonist of your story, you can use any kind of project, or all of them, and you can write with confidence. ”

"Thank you, Brother Gu Chen. Getting Gu Chen's guidance, Nie Xiaoyu was overjoyed.

Originally, I searched for information for many days, but I didn't gain anything.

But here in Gu Chen, just after a meal, Gu Chen helped her sort it out clearly.

Nie Xiaoyu was so excited at the moment that he didn't know what to say.

"Brother Gu Chen, your memory is simply superb, you can remember every name so clearly, is your brain an encyclopedia?"

"Haha. Gu Chen laughed dryly, but found that he had already been surrounded by many new and old comrades.

The old comrades still know Gu Chen's memory, but Gu Chen is so straightforward in front of everyone, which makes many people feel that the gap between him and Gu Chen may not be able to catch up in two lifetimes.

Some of the old comrades who were transferred to the Furong Branch from other units were already jealous of Zhao Guozhi's excessive fancy to Gu Chen.

But now it seems that Zhao Guozhi's preference is reasonable, who doesn't like such a policeman?

"Gu Chen, it's okay. An old comrade who was transferred from other units to the Furong Branch applauded excitedly after listening to Gu Chen's explanation.

The entire huge Furong branch canteen suddenly began to think of the applause sporadically.

Soon, the applause at the scene was thunderous, and everyone spontaneously applauded Gu Chen.

It's not because Gu Chen helped Master Nie's daughter Nie Xiaoyu solve problems in the canteen and was able to eat for free, but because of Gu Chen's super memory, he once again conquered everyone's cognition.

A person's super brain can be used so skillfully, no wonder Gu Chen's efficiency in handling cases can always rank first in the sub-bureau.

At this moment, everyone wants to say that it is not okay to disobey Gu Chen.

Gu Chen was also embarrassed enough by everyone's applause, so he looked around and saluted everyone.

Then he pulled Lu Weiwei, Yuan Shasha and Officer Wang and quickly left the scene.

......

......

2 p.m.

Three groups of offices.

Several police officers led by He Junchao all walked into the office with a swagger.

As soon as he entered the door, He Junchao went straight to Officer Wang's seat, took off his police hat, lit his head in front of Officer Wang, and asked, "Are you okay?"

"It's ugly. Officer Wang said.

"You still let us deal with the ugliness?" He Junchao was quite dissatisfied.

"I mean, you're ugly, and you feel like a bandit in the mountains when you shave your head like this. ”

"Hahahaha!" Lu Weiwei couldn't stop laughing on the side, and couldn't help but say: "Don't say it, if you want to control this hairstyle, it's really not everyone can do it, what Lao Wang said is not wrong at all." ”

Yuan Shasha also smiled: "And I see that some people on the Internet say that diamonds have the same composition as carbon, they have no value, and they are all scams of diamond dealers." ”

"Now it seems that the words can't be said like that, so Senior Brother He and Senior Brother Gu are still the same composition, why is Senior Brother Gu everyone rushing to ask for it, but Senior Brother He is not wanted?"

"Haha, Xiao Yuan, you are ruthless enough. Yuan Shasha, who usually doesn't speak to the point, spoke amazingly today, which made Lu Weiwei marvel and couldn't help but stretch out her thumb.

He Junchao had a black face, put a police hat on his head, and shook his finger at everyone: "Okay, you guys one by one, trick us into getting this haircut." ”

"Standard? What is a standard? Gu Chen's family is good-looking, we also know how many catties and taels we have, but it's not as ugly as you say, right?"

"And I think that judging whether a man is reliable or not can't be judged by his appearance, there are also bad people who are good-looking, and there are good people who are ugly, and bad people don't write the word 'bad' on their faces. ”

Looking at Gu Chen, He Junchao suddenly said: "Let's take Gu Chen as an example, his appearance is decent, and if he wants to act in a TV series, he is a proper protagonist, but Gu Chen also has a weakness, right?"

"Soft ...... Weakness?" Lu Weiwei and Yuan Shasha were stunned at the same time, looking at Gu Chen unconsciously.

When Gu Chen heard this, he also looked up at He Junchao, feeling that he had been shot inexplicably, so he hurriedly asked:

"Senior Brother He, you said that I have a weakness, so what is my weakness? Can you help me point it out, and I can improve it. ”

"I can't change it. He Junchao smiled: "You Gu Chen can't be an undercover agent, you look too decent, if you are thrown into the pile of bad guys, you Gu Chen will have 'justice' written on his head, no matter who it is, he will look at you twice." ”

"Poof!" Hearing this, Lu Weiwei was the first to hold back, and laughed directly: "But why did I hear you say this, it seems that you are praising my senior brother Gu?"

"This ...... How can this be a boast? It's clear that he Gu Chen can't do it, you can look at me again. He Junchao suddenly glared at him, showing himself as a fierce and vicious look, and then said: "Do you see it?"

"Hahaha!" Lu Weiwei couldn't laugh all over, and hurriedly took a picture of He Junchao's funny expression with her mobile phone, and then said: "It's too similar, you are clearly a bad person." ”

"Isn't that what it takes? When He Junchao heard this, he retracted his expression and said: "Everyone has their own position, I admit that Gu Chen does have extraordinary talent in handling cases, but he can't deny me?"

"Although I am a little different, I can be qualified for roles that Gu Chen can't do, such as undercover, in this regard, I think I can do better than Gu Chen, right?"

Lu Weiwei shook her head: "That's not necessarily, which criminal gang boss have you ever seen must be fierce and vicious?

Yuan Shasha also smiled and said: "That's right, if Senior Brother Gu goes undercover, maybe he will rise to prominence step by step, and he may directly become the boss of the other team!"

"Hahaha!" there was another burst of laughter in the office.

Quite a few other comrades, old and new, are laughing.

He Junchao's whole person is also depressed......

It's right to think about it this way, if the boss of the other party's criminal gang has a daughter, just let Gu Chen handle it, this kind of bridge is not impossible.

The next step is for Gu Chen to become the successor of the boss of the criminal gang, and then directly destroy the gang.

"Let's give it a go. Seeing He Junchao standing in the passage and meditating, Officer Ding directly squeezed He Junchao away with a thermos cup, and chuckled at He Junchao: "I said He Junchao, it's okay to learn more from Gu Chen, don't fix those useless things all day long." ”

"If you want to handle the case well, at least you need professional knowledge to make reserves, why Gu Chen can handle cases more efficiently than you, have you seriously thought about it?"

"Ugh!"

He Junchao was stunned for a moment, and just wanted to speak, Officer Ding immediately said: "That is, to paraphrase what you just said, to judge whether a man is reliable, you can't rely on his appearance, but on what he does after work." ”

"After you get off work, you just lie down, watch TV, and play games, and after Gu Chen gets off work, you have to seize the time to learn knowledge. ”

"The gap between people lies in the secret practice after work, your foundation is not good, and if you don't work hard, how can you surpass Gu Chen?"

"And Gu Chen himself has talent in all aspects, people have to study self-discipline after work every day, it is inevitable that people will succeed, and if you succeed, it is called chance, and that is called luck. ”

"You and Gu Chen are both 24 hours a day, this is fair to everyone, if you can figure out how to arrange these 24 hours, then you will succeed, so it's okay to compare this and that, isn't it interesting? ”

"Hehe!" was also counted by Officer Ding in public, and He Junchao couldn't wait to find a hole to get into.

That's right, He Junchao has always been like competing with Gu Chen, especially in front of Lu Weiwei, always trying to find his own shining point.

Before Gu Chen came, the strength of the three groups of male police officers was mediocre, and He Junchao could still have some bright spots in front of everyone, at least he had the best relationship with Lu Weiwei.

But after Gu Chen came to the third group, Lu Weiwei only had Gu Chen in her eyes, which made He Junchao involuntarily list Gu Chen as an imaginary enemy.

Thinking that one day she would be able to show her skills in front of Gu Chen, Lu Weiwei was impressed.

However, the old comrades should see the problem more thoroughly than the younger comrades.

Officer Ding hit the nail on the head, and was stunned to analyze He Junchao's problem clearly.

At this moment, Gu Chen also saw that He Jun was more than embarrassed, so he walked up to him with a document and said, "Senior Brother He, I don't understand this thing, I need to use a computer to operate it, why don't you help me?"

"Good...... All right. He Junchao knew that Gu Chen was looking for steps for himself, so he readily accepted: "This is not very difficult, or leave it to me, and then give it to you." ”

"Then thank you, Senior Brother He. Gu Chen patted He Junchao on the shoulder.

But at this moment, the landline phone next to him suddenly rang, Gu Chen turned around, and then picked up the phone and said, "Hello, this is the third criminal investigation team of the Furong Branch, how can I help you." ”

"Comrade policeman. On the phone, a man's crying voice was heard, but there was no movement for a long time.

"Hello, can you hear me?" Gu Chen asked again.

"Hear me, comrade policeman. The man sniffed, and then added, "My father is gone, and I suspect he was killed." ”

"What...... What?Your father is gone?" Gu Chen frowned, then quickly took out a writing pen from his body, pulled out the cover of the pen with his teeth, and said, "You speak slowly, I remember." ”

"That's right. After the man calmed down for a while, he choked up and said, "Today was originally the wedding anniversary of my father and my stepmother, and the two of them drank at noon to celebrate. ”

After that, the two of us went for a walk outside the house, and when my father went back to the house to take a shower, he died in the bathroom of his own house. ”

At this point, the man could not hide his grief and interrupted the conversation.

Gu Chen hesitated for a moment and asked, "Then how did you know?"

"It was my stepmother who told me. The man choked up and said, "She told me and my brother that my parents were gone in the shower at noon, and asked me and my brother to hurry home." ”

"However, I think there is absolutely something strange about this matter, and my dad's death must not be so simple, so I have to call the police. ”

After Gu Chen recorded, he also said lightly: "Then you mean that you suspect that someone has harmed your father?"

"That's right. The man's tone was very firm, and he continued: "You don't know the situation of my family, in fact, in our family, the relationship is very complicated, far from ordinary people can imagine. ”

"So, I would like to ask you police to come forward and investigate the cause of my father's death, my father must not die in the bathtub for such an innocent reason. ”

"Okay, I got it. After Gu Chen completed the record, he asked again: "Then can you tell me your address, and we will come over." ”

"Riverside Villa Garden, Villa 18. The man said.

Gu Chen was stunned for a moment.

Riverside Villa Garden, this is a rich area in Jiangnan City, and it is a top rich area.

Not only can you enjoy the beautiful scenery of the riverside, but there is also a wetland park nearby, which can be described as a natural oxygen bar.

Moreover, there are several international schools around the Binjiang Villa Garden, which are among the best in the entire Jiangnan City.

It can be said that as long as you mention your address in Binjiang Villa Garden, as long as you are a local citizen living in Jiangnan City, you will all look at it differently.

It's like in ancient times on the streets, where ordinary vendors ask customers where their homes live, and customers answer the Forbidden City.

That's kind of awesome.

can live in the Binjiang Villa Garden in Jiangnan City, as far as Gu Chen knows, at least the assets are jumping from 100 million.

Thinking of this, Gu Chen had already recorded the address completely, and then hung up the phone.

"Senior Brother Gu, what's the situation?" Lu Weiwei knew when she saw the change in Gu Chen's expression that there must be something new.

Gu Chen showed the transcript to Lu Weiwei: "This time in the Binjiang Villa Garden, someone was negligent in taking a bath in the bathroom at noon, and his son suspected that someone had framed him, so he called the police." ”

"Riverside Villa Garden?" When Yuan Shasha heard this name, her whole person was also stunned, and she seemed to be very surprised.

"What's the matter, Xiao Yuan, haven't you heard of this place? It's the top rich area in Jiangnan City. Lu Weiwei is also inexplicable.

Yuan Shasha hurriedly shook her head: "No...... Nothing, as if I had heard it. ”

"Then what are you waiting for?" Officer Wang was already getting the equipment, looking at Yuan Shasha with a sluggish look, so he asked her, "Is Xiao Yuan going?"

"I ...... I'm not going. Yuan Shasha hurriedly refused.
