I said: "The yin spirit I sensed is not very old, similar to Xiaoxiao, died at such a young age, and the whereabouts of the body are unknown, the family of the deceased should have reported the case back then, the police must have investigated, no accident This is an unsolved case, the police will have a record, as long as we hand over the things, it will definitely attract attention, we will find the criminal police team first, find a way to hand over this picture to the police, as for what method can be used without exposing us and we can hand it over to the police ......." ”

As I was talking, I suddenly noticed Wang Yong, who was sitting in the corner of the room playing with a slingshot, and I had an idea, and went over and said, "Dayong, are you good at playing with a slingshot?

Wang Yong said proudly: "Of course it's amazing, I'm the first in the class, I've been playing slingshots since I was a child, I used to go to the mountains to hunt birds when I was in elementary school in the village, I'm a marksman, and the little sparrows in the trees fifty meters away can be hit." ”

Wang Yao came back to his senses first and said: "Dayong didn't brag, when he was a child, he didn't play much at home, his grandfather gave him a slingshot as a gift, he has been playing with slingshots since he was a child, I once had the idea of sending him to the shooting team, I don't know if I can win glory for the country and get an Olympic medal or something in the future." ”

I couldn't help but laugh.

Wang Yao and I set off with Wang Yong first, and on the way I said: "Brother Wang, your son has cultivated well, this time I went to the school to investigate thanks to him I was able to find so many clues, and now I have to use his slingshot technique, which helps a lot." ”

Wang Yaoxian just smiled slightly, his expression was a little solemn, he estimated that something was wrong in his heart, I asked him what was wrong, he said: "I'm a little unsure, you see, we are doing so many things now, all based on the corpses buried under the playground, in case there is no corpse, we are not in vain, and we will delay the time to save my niece?" Master Luo, don't get me wrong, I'm not questioning your judgment, I just think it's hard for me to understand the murderer's approach, you think, it's not suitable to hide the body in the playground, how could the murderer bury the body on the playground without the heart and eyes, and hide it in a more hidden place. ”

Wang Yaoxian's worries are not unreasonable, I said: "According to the logical thinking of normal people, it is true that it will not be hidden in the playground, but it can be understood by using reverse thinking." ”

Wang Yaoxian was curious: "What is reverse thinking?"

I said: "The popular understanding is to think the opposite, if nothing else, this yin spirit is dead on campus, and the murderer can only choose to hide the corpse on the campus in a hurry, what is the campus place? There is no good place to hide the corpse at all, there is a saying that can reflect reverse thinking, this is the most dangerous place and the safest place, so it is not impossible to choose the playground." ”

Wang Yao nodded first and said, "It does make sense to say that, so the murderer may be someone from the campus?

I said, "It's not like a student can do it so calmly in the face of murder and corpse disposal, I suspect it's the teachers and staff in that vocational and technical school back then!"

Thinking of this, I took out the floor plan and marked another line on it, reminding the police that the murderer might be a faculty member of the vocational and technical college back then, so that the police could narrow down the scope of the investigation.

But all of this must be based on the fact that the body is hidden under the playground, otherwise we will confuse the eyes of the police by doing so, and the crime is not small, I hope my speculation is not wrong!

We chatted and arrived at the gate of the compound of the criminal police team, the back door of the criminal police team is a small road, there are not many pedestrians, and there are big trees, I asked Wang Yong to climb the trees to have a look.

Wang Yong climbed up and said that he could see the office, and there was a police uncle inside.

That's easy to do, no matter what kind of office it is, in short, the police within the criminal police team will definitely report if they find out the clues we have provided.

Wang Yong found a small pebble, wrapped the flat paper ball, and then used a slingshot to shoot the paper ball into the window, and then quickly climbed down the tree, we quickly hid under the wall of the courtyard wall, and soon there was movement inside.

"Xiao Zhao, go to the back door to see who is so bold and dares to throw things into the criminal police team. ”

Wang Yao and I glanced at each other, nodded, and then quickly walked away from the criminal police team.

We parted ways at the intersection, Wang Yao first said that he would send Wang Yong back, otherwise his daughter-in-law would be suspicious, and I said that I would go to school first and wait for him.

When I came to the school, I was still waiting in that bubble tea shop, and the police would definitely study and judge after receiving the clues we provided, and they would definitely come, but it was hard to say how long it would take.

About an hour later, Wang Yaoxian came to meet me, and we waited there together, until it was dark and no police came, Wang Yaoxian couldn't help but be a little anxious, and said, "Master Luo, do you think the police won't pay attention to it, no matter what?"

I shook my head and said, "It shouldn't be, this is a homicide, I don't believe that the police won't come to verify it, digging the playground on campus is not a small matter, the impact is very great, the police will definitely have a lot of concerns, be patient." ”

Wang Yao sighed first, and had to wait patiently.

We waited until 8 o'clock in the evening, the bubble tea shop was closed, and the students began to study at night, and the police did not come, and the two of us were hungry and cooing, and we did not dare to leave the school gate, so we had to find a convenience store with a view of the school gate and buy two buckets of instant noodles, which was simply for dinner.

Two men came to the convenience store during dinner, and although they were not wearing police uniforms, I could tell from their temperament that they were police officers.

I reminded Wang Yaoxian, who nodded first and said, "It's like a policeman." ”

Two plainclothes policemen bought mineral water and cigarettes at the convenience store and sat down in the chairs behind us to chat.

A young policeman said, "Team Qin, do you think we will be tricked?"

The older Qin team said: "Who eats a leopard and dares to play the police, and he is still a criminal policeman?"

The young policeman said, "That's true, then who do you say this person who threw the clue at our criminal police team, is it possible that he is the murderer? ”

Hearing this, Wang Yaoxian and I were excited in our hearts, the plan was successful!

We ate instant noodles for fear of being overheard.

Team Qin said in a deep voice: "I don't see it. ”

The young policeman said, "Why?"

Team Qin said: "You have only been in the team for a long time, and it is normal that you can't analyze it, why do I say this to analyze to you, learn a little, do you think, if it is a murderer, why would he do this? The biggest possibility is out of guilt, according to my many years of experience in handling cases, most of the murderer's guilt will come to surrender himself, why bother throwing paper balls to attract our attention, and specifically explain that the murderer may be a faculty member of a vocational and technical college? And then let us investigate and arrest him, isn't this an extra move?"
