my life is running wild

Chapter 183

Li Xian'an was deeply impressed by this case, which had been declared a failure just after it was discovered.

This allowed him to describe the scene of the case and the transcripts of the victim's neighbors, landlords, family members and others in great detail, as if it happened not long ago.

It can be seen that he did not give up easily at that time. He checked a lot of things. During the process of checking, he kept these information in his mind, and he still has a deep memory to this day.
Of course, it does not rule out the possibility that Li Xianan's own memory ability is very strong. To be able to achieve the position of chief of a municipal police station, his comprehensive ability in the field of police must be ahead of most of his peers.

"People always joke that 'justice is always late', but in fact, in many cases, even thinking about 'being late' has become a luxury, and in the end it can only be regretted 'absent'." After speaking about the case, Li Xianan finally expressed emotion said such a sentence.

At first, Liu Chengyin listened to the case explained by Li Xian'an with the idea of ​​chatting to relieve boredom.

But Liu Chengyin was infected by the strong emotions carried by Li Xianan's words, and unconsciously sympathized with Li Xianan's experience to a certain extent.

Relying on the imagination of [Perfect Perception], while listening to Li Xian'an's narration, Liu Chengyin subconsciously imagined in his mind what the scene of the crime would look like based on what he said, and what Li Xian'an told the victim's neighbors, fans, family members, etc. The screen when waiting for someone to make an inquiry.
Where did the victim go?

What happened then?
Who is the murderer?

Is the victim alive or dead?
Or, is the victim really a victim?

Looking at the picture in his mind, questions and possibilities popped up in Liu Chengyin's mind, and then he tried to find something based on these clues.

Liu Chengyin fell into deep thought.

After Li Xian'an finished talking about his troubles, he wanted to share his feelings with other people, but found that the whole box seemed strangely quiet.

At this time, Zhang Gang spoke, and he whispered: "Director Li, don't worry, our boss may have thought of something. The last time he acted like this was this afternoon, and then he found out that the 'Jie' bandit'!"

"That's right." Ma Quan nodded and agreed.

When Li Xianan heard what Zhang Gang and Ma Quan said, he was first taken aback, then surprised, then joyful, and finally shook his head while smiling wryly. Take advantage of the shade.

In Liu Chengyin's thinking, a few minutes passed quickly.

After ten minutes of hard thinking, Liu Chengyin finally came to the result
First of all.

Well, this is indeed a no-nonsense case that makes Li Xianan, a veteran policeman who is capable enough to be the director, feel that he has no way to start.

The case was tricky.

At first, Liu Chengyin tried to challenge it with his own ability, but after thinking about it for a long time, he had no clue at all.

Well, this is a very normal thing, after all, Liu Chengyin is a pure layman when it comes to investigating cases when he is not cheating.

Under the anticipation of Li Xianan and others, Liu Chengyin finally chose to hang up and use an "analysis" on the imagined picture in his mind.
In "Analysis", Liu Chengyin saw that the imaginary crime scene that had become messy during the struggle of the victim and the fight with the gangster began to be transformed according to some "constraints" involving physics, psychology, chemistry, etc. "Reverse derivation" went back.

For example: a glass that was originally broken due to a fall, under the reverse push based on these laws, the broken pieces re-condense and become intact again, and then "float" into the midair, where "Copy" many copies of the same one, and then return to those places where it "may" stay before landing.

Apart from the broken cup, the same is true of other details mentioned by Li Xianan.

Soon, Liu Chengyin imagined that there were many things in a state of "superposition" in the whole room as the crime scene.

In a blink of an eye, the "possibilities" of all "events" were listed by [End Decryption].

"Parse" continues.

Then, by relying on each "event" to corroborate each other, those contradictory "possibilities" are excluded.

Like this, when encountering a problem, list all the possibilities first, then try one by one, eliminate one by one, and leave the final answer. The solution to the problem is called "exhaustive method".

So what?

It feels a bit like playing "Sudoku".

Uh. In other words, using this method to play the "Sudoku" game basically does not require any brains. As long as you continue to "screen" according to the constraints according to this kind of thinking, you will be able to pass the level in the end.

Soon, in the continuous "screening", more than half of the things in the "superimposed" state disappeared instantly, and some things even broke away from the "superimposed" state, and were returned to the state they were in before the incident.

The reason why the remaining part is still in the "superposition" state shows that their "constraints" are not sufficient.

In this case, either Li Xian'an's description was not detailed enough, or he made a mistake, or there was an omission.

But this is normal, after all, it happened a few years ago, Li Xianan can tell such information from memory without looking at the file, it is already very powerful.

Put things in the "superposition" state aside first.

Things that come out of the "superposition" state are in the state they were in before the incident.

According to the comparison of the state before and after the crime, the process of their state being changed by external force can be deduced
As for the victim's height, body shape and approximate weight, Liu Chengyin had already learned from Li Xian'an.

Start the simulation!
The next moment, Liu Chengyin saw two "Xiao Hei", one of which had the same height, build, and weight as the victim, and the other "Xiao Hei" had a blurred "marginal line" and was in the future. OK status.

Then, the two "little blacks" began to make various "actions" in the room facing these "out-of-superposition" things under the "conditions" of "fighting" and "struggling".

Under the constraints of known conditions, these messy movements were finally brought to an end, leaving only a handful of movements, or even just one!
Only these actions can make these "out of superposition" objects change from the state of "before the crime" to the state of "after the crime".

Then, continue to "parse" and continue to "screen".

Yes, this is also a "screening"!
It's as if at the same level, a person who is two meters tall cannot hit the knee of a person who is one meter tall with an uppercut;
On the same plane, people whose heights differ by half a meter cannot kiss with their heads up
The environment, the characteristics of the victim's body, and the actions of "interaction" with each other will all become "constraints" for screening criminals' physical characteristics.

Under this selection, the originally blurred boundary line of Liu Chengyin's "Xiao Hei" who represents the gangster gradually became clear.
In this way, Liu Chengyin knew the criminal's approximate height, body shape, weight, handedness, and some minor physical problems exposed during movements.
Of course, this is assuming that there is only one criminal.

Now, start assuming that the culprits are two people.
simulation
failure.

When there were two criminals, the victim could not struggle and resist to this extent.

Not to mention the other numbers.

So, make sure there is only one culprit.

After the "analysis" of the information at the crime scene was completed, the "records" began to be added.

Neighbors, landlords, relatives, colleagues, and friends of the victim participated in assisting the police to record the transcripts.
Start with the known information first.

Therefore, the "analysis" of Mo De's feelings directly uses their physical characteristics to compare with the gangsters.

After the comparison, it was found that the height, shape and weight of several people were just within the "possibility" range of the gangster
Among the three people, there are relatives, acquaintances who have a relationship, distant or close, and some are almost strangers.
Based on the "interaction" between the two "little blacks" in those "actions", we began to speculate on the relationship between the two.

acquaintance?

relatives?

stranger?
After a series of investigations.

In the end, Liu Chengyin found that among the known people, there was a person who could not be screened out through the known "constraints"——

landlord!

But this does not mean that Liu Chengyin can be sure that the landlord is the murderer.

It cannot yet be ruled out that the culprit is someone other than "known".

Further "analysis" requires more conditions to ensure that the "sieve" woven by these conditions can only screen out one "possibility".

When all the impossibilities are eliminated, at that time, the "possibility" that is finally screened is the only "truth"!
However, the information Liu Chengyin has so far can only do so.

To proceed to the next step of screening, he needs more information.

At this point, "analysis" ends.

Liu Chengyin raised his head, and then said the important information that he "analyzed" and could confirm.

When Li Xian'an saw Liu Chengyin's determined expression in front of him, he said the information he "analyzed" about the gangster's height, weight, body shape range, and a few "minor problems".

Li Xianan was dumbfounded.

This is to see the "fairy"!

Is this guy really human?
Could it be that this guy is really a "super brain"?
However, even if it is really a "super brain", the "levels" of ordinary people like us that your brain has "surpassed" are too many, right?

Does this brain really not consider "handing over to the country"?

Stop making movies, making music, etc., do research, help research...or be researched.

Maybe because of this brain, the country's development time can be shortened by a few years or a few months?
Li Xian'an doesn't know much about scientific research, but it should be useful anyway.

Li Xianan was dumbfounded, Liu Chengyin finished all the things he "analyzed", and finally asked:

". That's it for now. To confirm further, I need more detailed information.

These should not be what you said you collected all of them, right?
Do you keep more detailed files there?

For example, photos, or similar evidence clues?

Of course, if I don't let outsiders see it, I didn't say it! "

After Liu Chengyin finished speaking, Li Xianan continued to be stunned for a few seconds, then stood up abruptly:

"Yes! You can watch it! Go, I'll take you to see it!"

However, Liu Chengyin didn't get up, and seemed to be hesitant.

Li Xian'an thought of Liu Chengyin's concerns, and explained: "Our police are not omnipotent, it is impossible to understand everything.

Although there is no such profession as 'detective' in our country, we will temporarily hire experts in related fields to assist when the knowledge we have learned cannot be verified.

For example, forensic doctors are part-time jobs for some medical staff. After all, our cases are not so rich that forensic doctors work eight hours a day.
Even, our police station usually hires some experts for a long time to serve as consultants or something in our police station. "

After listening to Li Xianan's words, Liu Chengyin nodded: "Then I can rest assured. However, this is only one aspect, another aspect"

Li Xian'an: "Could it be that there is something that we can't get away from? Or maybe, I'm in a hurry, we can't let the masses do free work for us, let's talk about the issue of remuneration and bonuses."

"No, no, no! You have misunderstood! I have nothing to do, and I am not worried about money. I am not short of money." Liu Chengyin waved his hands repeatedly.

Li Xianan: "What exactly do you mean?"

"What I mean is..." At this point, Liu Chengyin pointed to the table: "We haven't finished our food yet, don't waste food, and you seem a little too excited now, driving like this is dangerous, besides , It’s been a few years, it’s not too late.”

"Crack~"

Li Xianan patted his forehead: "Yes! I'm too excited, I can't waste food, and I can't drive the 'top car'. Come, eat!"

Although I said so, but because I knew that Li Xianan was going to deal with the case in a hurry, in the following time, everyone didn't have the leisurely mind to taste it slowly at the beginning, and basically gobbled it up.

Fortunately, at this time, everyone has almost eaten.

A few minutes later, the four of Liu Chengyin finished off the rest of the meal without wasting any food.

More than half an hour later, Liu Chengyin and the others arrived at the D City Police Station under the leadership of Li Xian'an.

In the midst of the turmoil, Liu Chengyin and his party soon arrived at the archives of the D City Police Department.

As soon as he entered, Liu Chengyin could see the densely piled file bags on the shelves of the archives.
Just when Liu Chengyin was thinking about how Li Xianan would find the files they wanted from so many files.

Li Xianan checked it with the computer in the archive room, then drew a circle in a direction, and said to Liu Chengyin and the others:

"I'm sorry, there's not enough manpower at this point, please help me, look for it together, on that row of shelves, the area that starts with XX, there are a lot of them"

Liu Chengyin looked at the area drawn by Li Xianan.

After reading it, Liu Chengyin heaved a sigh of relief.

After estimating, the pile of files seems to be specially sorted out, not many, only dozens or hundreds of files, um, compared with the "pile" next to it.

not much.
