After coming out of the school, the police put the case filing materials, evidence, and confessions in a file bag and put them in the car.

The young policeman started the engine and asked at the same time, "Team Zou, why did you scare that kid just now?" I mean, knowing that he's not the guilty. ”

"Xiao Cheng, how do you know that he is not a criminal?" Team Zou asked.

"First of all, I don't think he's lying, you know I'm a psychology student, and you can see a lot of details. Secondly, judging from the extent of the damage to the car and the length of time it took to commit the crime, it did not look like a schoolboy had done it, and most importantly, who would leave his test paper on the spot? ”

"In other words, if your psychology is unreliable, he has other accomplices who commit crimes, and he deliberately leaves his test papers on the spot, then your reasoning is not valid?" Team Zou asked rhetorically.

Xiao Cheng was a little annoyed, especially when he heard the other party say that he was "psychologically unreliable". The Zou team is an old bird in the police force, usually amiable, but occasionally said words like sharp knives, which can make people angry to death.

"Xiao Cheng, don't underestimate the other party just because they are elementary school students," Zou said, "There are all kinds of people in the cases I have handled, covering all ages, and some people's psychology is not effective at all." ”

"So you think Yan Xiaojun is the perpetrator?" Xiao Cheng was not convinced.

The police car stopped at the entrance of the police station, and Team Zou said: "That's not it, as you said, he doesn't look like he is lying, and I heard that he is not very gregarious in the class, and it is unlikely that a person will injure the car like this......"

Xiao Cheng scolded in his heart, Damn, isn't this what I just said?

Captain Zou continued: "Then why did the criminal leave Yan Xiaojun's note? ”

Xiao Cheng said: "Are you going to blame him?" This is in line with the idea of elementary school students. ”

Team Zou took out the evidence and handed it to Xiao Cheng: "I told you not to underestimate elementary school students, look at what else is strange on this piece of paper?" ”

Xiao Cheng took it over and took a closer look, and found that there were obvious traces of eraser erasers on it, and some of them could even vaguely see the answers left before, and the score was ......

"Did you find out? This and this are all correct answers until they are erased, and even this difficulty is done correctly, is this paper like a 39-point paper? The old sheriff said meaningfully, "As for the score, do you think the cropping position happens to fall to the left of the '3' of the '39'?" ”

"What do you mean?"

Team Zou pointed to the score and said, "If you make up the part to the left of '39', wouldn't it be like '89'?" I've checked my grades, and there are a lot of grades with a '89'. ”

"You mean, this scroll is not Yan Xiaojun's?" Xiao Cheng's eyes widened, "Why the hell are you doing this?" ”

"No, that's not what I meant. You might as well think a little deeper, if he ...... I'm assuming it's Juvenile X, what if Juvenile X guessed that we would find something strange about the test paper and deliberately tampered with the test paper? In other words, this was originally a 39-point roll, so he made us think it was an 89-point roll to confuse our sight? ”

Xiao Cheng was taken aback: "Then we will think we have guessed his plan and be sure that the score is '89'!" But for the purpose? He wants to blame Xiaojun, but he tells us that this is the blame......"

"I want to cover up, but I deliberately use it to cover up the deeper purpose," the old sheriff also fell into deep thought, "It's like a thinking trap, and it may be endless to think about it like this." Suppose the test paper was supposed to be 89 points, and he pretended to use 39 to lure us into finding out that it was 89, and then made us think it was a trick and went back to the 39 guess...... Just like playing chess, the praying mantis catches the cicada and the yellow finch is behind, but I don't think that there is an eagle hidden behind the yellow finch, and the last person who is higher in chess is the one who stands at the top and sees the last person. ”

"Wait, Team Zou," Xiao Cheng's words brought him back to reality, "how can you say that he is also a student!" Do we need to be so indecisive? No matter what his purpose is, it is certain that Yan Xiaojun is involved, and it will definitely not be wrong for us to start with Yan Xiaojun. ”

Team Zou couldn't help but praise: "There is progress, Xiao Cheng, that's right, the best thing to do now is to withdraw from the mystery and cut into the essence from a different angle." Since the other party has involved Yan Xiaojun, there must be expectations for him, and at this time, they will inevitably contact him in some way again......"

Xiao Cheng snapped his fingers: "Amazing, Team Zou!" That's why you have to warn Yan Xiaojun at the end that he is the purpose of the biggest suspect? Just to keep him vigilant and keep an eye out for the real prisoner who wrote the note! ”

Team Zou nodded in satisfaction, and then walked out of the car. The scorching sun outside, he suddenly had an illusion, as if he was climbing a mountain, but no matter how high he climbed, there was always a person staring at him above, this person stood on the top of the backlit mountain, and all he could see was a dark outline.
