All the surveillance in this school is carried out under the supervision of the school guard room, and all the previous surveillance videos can be found here, and after Zi Yuxun and others identified themselves, the doorman understood what the other party was doing here, and he was very cooperative to open the video.

After observing the school's surveillance video, Zi Yuxun found that there was indeed a strange vehicle at the school's gate during the time when the director was killed, and the vehicle successfully entered the school just by flashing the sign, which shows that this car is definitely an acquaintance.

When Zi Yuxun asked who the porter was, the other party said that this person was the teaching director, and the sign in the other party's hand was a special pass sign for the teaching director, and the other party said that if he wanted to come back to get something, he needed to use it for a meeting, so he came so anxiously overnight.

Zi Yuxun really feels a little unreasonable for this question, you know, the director of teaching is already a big acquaintance of the school, and acquaintances still need to show signs when they enter the school? This is obviously unreasonable, unless there are some special requirements that must be shown before they can enter.

Under the introduction of the concierge, Zi Yuxun realized that the person on duty in the school that night was not the old concierge but a new concierge, because the old man's body couldn't bear it, so he would choose to change to another young concierge at night to see the door.

Because the new gatehouse has just arrived, he will choose to let each vehicle show the brand equipped in his school to prove his identity, and Zi Yuxun also feels that the other party is indeed quite responsible, so he didn't say anything more, and the problem that needs to be paid attention to now is this car.

The person in this car was the victim's dean of education, but if the other party was killed, the car should not have left the school, but after a period of observation of surveillance video, Zi Yuxun found that the car left the school gate ten minutes later.

After finding the person in charge of the night shift, Zi Yuxun asked in a low voice: "Did you see the person driving the car when the car left?" After hearing Zi Yuxun's inquiry, the person guarding the door nodded, as if to respond that he saw it.

"So when the car you saw left, was the person driving the car the same as the person who came in?" because Zi Yuxun guessed that the other party was likely to drive away in the dean's car after killing the dean, so that he could be unaware, but the porter could see it.

And after the porter's recollection, he responded that the person who drove away was the same person when he entered, and there had been no change, which made Zi Yuxun feel very surprised, since the teaching director was not killed, then how should it be achieved after this?

You know, the dean of students has never entered the campus since then, so if the dean of students did not enter the campus, then how would these murderers transport the bodies to the school?

The investigation could only be halted for the time being, after all, there were no new clues to prove whether their inference was correct, after which they waited to find the headmaster, who had now successfully returned to the school, and believed that some good information would be available soon.

When the police saw the principal sitting in the office, Zi Yuxun could see drops of sweat on this person's forehead, if this was an ordinary time, then it was probably proving that this person was weak, or something made him nervous.

But the other party has just rushed back non-stop, and it is natural to encounter some nervous things, and it is natural that there will be some nervous things, and a strange aura is gradually emitted from this person's body, which really makes people feel a little helpless, and it is not clear what is going on.

"Headmaster, I know that this news is indeed a bit shocking to you, after all, no one can accept it immediately when they learn that a body has suddenly been found in their school, but you need to calm down first, we need to know some relevant information from you, please cooperate." ”

When Zi Yuxun said this, his eyes kept observing the other party's face, he needed to make sure that every word that the other party said was true, otherwise, wouldn't the person with this clue be wasted, in the current stage of the investigation case, every clue is very important.

After the other party calmed down his nervous mood, Zi Yuxun continued to ask: "We learned that the victim education director went to a meeting with you outside during the murder, so why did he return before the meeting ended?"

"Hey, no one really regrets it, when I left, I left an important document in the school office, so I asked the other party to drive back overnight to get it, but who knows, he never appeared again when he came back. The headmaster whispered back.

Zi Yuxun was now able to make sure that the other party's words were not mixed with any water, and after that, Xiaolong on the side continued to ask, "Did you meet any people outside at that time who had a grudge against the teaching director, and were so resentful that they would kill someone's life. ”

"I haven't met this kind of person, you don't know that the popularity of the teaching director is still good, how can anyone have a grudge against him?" When he said this, Zi Yuxun found that the principal's face had a feedback of lies, and it remains to be seen why he lied.

"That's not right, we remember that after visiting and investigating in the school before, we found that the reputation of the dean in the school is not very good, and few people like him, but why do you say that the dean is popular?"

"This, you also know this, the director of teaching is responsible for the usual supervision, this kind of work is the most hateful, so it is normal for the relationship in the school to be bad, but for the usual life, he is still quite a good person. The headmaster continued to explain at this point.

"Okay, then the next question is, when the teaching director returned, was he alone, or was he accompanied, did the other party contact you after returning to the school?"

This is proof that Zi Yuxun found out that the principal was creating his own lie, and what exactly this lie would become, the two of them were really curious, and at this moment, the principal responded: "Yes, there is indeed a person following him." ”10
