I am a super cop

Chapter 3 The walnuts that were squeezed through the door can nourish the brain after eating them?
There was a burst of laughter in the conference hall, causing many passing policemen to take a few curious glances before leaving.

In fact, the reasoning operation is the most skillful, and the knowledge that needs to be used is all-encompassing. Even a criminal policeman who has worked for many years needs to continue to follow up and learn.

Xiao Yang glanced at Gu Chen, and then returned to the reasoning on the question board.

It is said that laymen watch the excitement and experts watch the way. Generally, those who are good at solving crimes can see the true level of a reasoner at a glance.

But from the perspective of solving a case, the time of committing the crime is generally placed at the forefront, but the motive for killing is also an indispensable option.

According to the reasoning given by Gu Chen, both suspects may have committed the crime, so finding out the specific time of death of the deceased, it is possible to find the murderer based on the time when the two were not present.

But Gu Chen's starting point is obviously doing a good job.

What surprised Xiao Yang the most was that Gu Chen's analysis on the time of committing the crime was also accurate.

"Gu Chen, tell me, why did you judge that the time of death was at night?" Xiao Yang asked coldly.

"Because of this photo." Gu Chen pulled the photo under the colored magnet back into his hand, and then took it in front of everyone to check it out.

Everyone knows that the murderer put the body into hot water to cover up the real time of death, but Gu Chen is talking about it with a photo, which is very puzzling.

"Gu Chen, is there anything different about this photo?" A trainee policeman in the queue asked him curiously, "Isn't it just a few feathers on the spider web outside the window on the second floor?"

"That's right, the investigation results of this question have already been mentioned. The crime scene was found in the bedroom on the second floor, where there were traces of fierce fighting, and the feather pillow was torn. There were white feathers everywhere on the floor of the room. Occasionally a few pieces Floating out of the window, what's so strange about it?"

Another trainee policeman asked.

Everyone started to look at each other and started discussing in low voices, but after all, no one could explain why.

Xiao Yang smiled, he knew that this photo was the key to solving the problem, but Gu Chen did a very good job.

Others didn't even think about why.

However, Xiao Yang was not sure whether Gu Chen really knew what the problem was, so he asked again: "Gu Chen, tell me your explanation."

"Okay." Gu Chen nodded, smiled and said, "This is how I understand it. The problem is not the feathers, but the spiders on the tree outside the window."

"spider?"

Many people said in amazement: "The time of committing the crime has something to do with the spider?"

"That's right, spiders can talk? I don't believe it." Lu Weiwei couldn't wait any longer, and she hurriedly said again: "Junior Brother Gu Chen, don't be fooled, and tell everyone what you know."

"Okay." Gu Chen smiled calmly: "The spider on the big tree played a key role in solving the case. According to the proportions, it can be seen that this is a tarantula about 25 centimeters long."

"This kind of tarantula is more poisonous than ordinary spiders. It relies on venom to poison the prey caught in the net before eating."

"And the white feathers from the feather pillow remained on the damaged web of this spider, so I can conclude that the time of crime was at night, because this type of tarantula is mostly active at night, they often weave their webs in the evening, and the next day Break the net again in the morning."

In this way, everyone will soon understand the time of committing the crime.

Feathers can be stuck to the damaged spider web, which only shows that the time of committing the crime is at night.

And the murderer is also obvious, that is the gambler Liu mentioned in the title.

"That's not right." Xiao Yang saw that Gu Chen's analysis was accurate, but he asked deliberately: "If it is a feather on the ground, and he floats on the broken spider web outside the window, then the time of committing the crime cannot be determined again?"

Xiao Yang's doubts immediately aroused the approval of many people.

Reasoning is the most important thing about logic. Although Gu Chen's idea is reasonable, if the situation Xiao Yang said happens, the reasoning of the time of committing the crime will not be easy to judge.

"Gu Chen, your reasoning is not rigorous." Zhao Guozhi, who was standing aside and paying attention silently, also said at this moment.

However, Gu Chen was not embarrassed, instead he said with a light smile: "This factor can be ruled out."

"Huh? How do you say it?" Lu Weiwei on the side was curious like a school monk listening carefully.

"Because it is affected by the factors of the falling trajectory of the object." The data flow in his mind surged rapidly, and Gu Chen shared what he knew:

"When the feather in the topic falls, its volume, shape and density will affect its trajectory."

"General density is a physical quantity representing the mass per unit volume of an object. The volume is the same, but the density is different, and the mass is different; objects with different densities fall simultaneously in a vacuum, and their trajectory is the same."

"When the density and mass are the same, solid and hollow, pill-like and flake-like, the falling trajectories of the objects are different, which is mainly related to the size and direction of the air resistance, so the situation you mentioned will not happen. .”

The crowd was amazed again.

Speaking of this, Xiao Yang is already very satisfied. He used many misleading clues, but Gu Chen was able to avoid them successfully.

Perhaps, this is Gu Chen's talent in certain aspects, but in the criminal investigation team, this is an important technique for solving crimes.

The various cases that the criminal investigation team has to face will always make people busy, but the most troublesome thing is the time to commit the crime.

Especially in the face of all kinds of cunning criminals, they often have strong anti-reconnaissance capabilities.

Xiao Yang has participated in the cracking of countless cases in the criminal investigation team over the years. In terms of clue collection and accurate judgment and reasoning, he thinks that Gu Chen's response is excellent.

Extraordinary talent, maybe it refers to people like Gu Chen?

Thinking of this, Xiao Yang couldn't help thinking of when he first entered the police force.

The same is a trainee policeman, and he is also facing the test of a veteran. The difficulty of his own questions at that time was not even as good as it is now.

As for the reasoning time, the Gu Chen in front of him only took less than 8 minutes to solve the problem he carefully prepared.

The last time I spent nearly an hour.

The gap... suddenly formed.

Xiao Yang didn't understand, how did Gu Chen develop this ability?
How difficult is it to master this technique?In terms of reasoning skills alone, this is completely different from training in a police academy, and there is a huge gap between theory and reality.

At the beginning, Xiao Yang himself specialized in criminal investigation. During his school days, his grades in all subjects were also among the best. He thought he could show his talents in the police force.

But in the end when I came to the police force as an intern, the things piled up with various theories suddenly became worthless.

No matter how many theories are piled up, it is not as good as the experience judgment of an old criminal policeman.

Today's police academy students usually use their winter and summer vacations to contact the corresponding police station to exercise their working ability in advance.

But those who can practice in the criminal investigation team are even rarer, not to mention that Gu Chen's winter and summer internship unit is still a little-known non-staple food supermarket.

"Does the supermarket sell walnuts that have been squeezed by the door? Eating them can nourish the brain?"

Xiao Yang has regained his doubts about the 5% that has existed for a long time in these years.
