Yuan Ruoruo didn't understand, the monitoring of their class was broken, and what clues could she find when she went to the monitoring room, but she trusted Xiao Yue.

He said to go, and there must be a reason.

For this reason, on the way to the school's security department, Xiao Yue explained to her: "Let's go and see the surveillance in the corridor." ”

If that person wants to "commit a crime", he will definitely find a time when there is no one in the classroom, and he will be alone.

The question of time, the two of them unanimously agreed that it was the time when the students went out for activities during the big recess.

The big recess starts at 9:45.

Therefore, when they arrived at the security department, they directly watched the surveillance in the corridor on the floor where the thirteenth class of high school was located from this time.

After another minute or so, the hallway was completely empty.

They never noticed anything out of the ordinary.

They started broadcasting gymnastics at 9:50 sharp, and each class would report the number of people before the exercises.

At 9:45, the bell rang on time, and students emerged from various classrooms in the surveillance footage, and then walked to the staircase in groups of threes and twos.

Remember https://m in a second

For three minutes, the people in the surveillance screen were not interrupted.

After three minutes, there were fewer people.

She had to run back to the classroom before everyone else did, and before everyone went back to the classroom, she had to unpack, cut holes, and wrap the package as it was.

Yuan Ruoruo looked at the surveillance screen while doubting his own inference.

Could it be that she didn't cut it between classes?

When Yuan Ruoruo was doing exercises, she stood relatively backward, just in front of the sports committee, and she didn't hear him say that the number was wrong.

Could it be that the man went back after doing radio gymnastics?

But her speed is too fast, right?

Feeling the girl's gaze, he turned his head and gave the girl a determined look, and raised his hand to rub the top of her head.

Yuan Ruoruo is depressed, irritable, annoyed, and aggrieved...... All the negative emotions are much weaker because of his warm but heart-warming movements.

The two of them glanced at each other, and then turned their heads to continue to look at the monitoring in tacit understanding.

It's just that before her idea was settled, a person appeared in the surveillance screen.

Yuan Ruoruo suddenly became excited, and she glanced at Xiao Yue.

He was still calm, but his eyes were noticeably deeper than before.

The body type of the girl is the most common body type in the school, so even if there is a high probability that it is a classmate who is sitting in the same classroom as Yuan Ruoruo, she still can't tell who it is for a while.

Of course, now they are not 100% sure that she is the "murderer!" ”

It wasn't until her figure disappeared at the door of Class 13 that Yuan Ruoruo was ninety percent sure.

Obviously, judging from the height and body shape and walking posture, there is a girl in the picture.

She came prepared, wearing a black cap and deliberately pressing the brim very low.

Everyone wore the same school uniform, and the shoes she wore on her feet were also the most popular sneakers at the moment, and many girls in the class wore them.

Coupled with the fact that there is no good reference, Yuan Ruoruo can't even determine the approximate height of that girl.

She could only check all the girls in the class one by one in her mind.

The position of the monitoring is better, and the visual sense from top to bottom will make people shorter.

Three minutes later, she left in a hurry, and Yuan Ruoruo was 100% sure that it was her!

But who is she?

The first to be excluded is Zhao Yule.

Then she excluded a few girls who were close to her doing radio gymnastics, and they didn't leave.
