Qingxi High School Monitoring Room.

Principal Lan called up the monitoring of the fifth class, and from the moment Copper Sulfate and Zhou Qian entered the classroom, he didn't dare to skip for a second.

However, nothing was found.

In the monitoring, it can be seen that everyone enters the classroom normally, hands in homework, and then talks and self-study.

Principal Lan's attention was focused on the two men

Zhou Qian and Hu Ling'er.

Zhou Qian is because he has a naughty history and is the first to enter the classroom.

And Hu Ling'er has more criminal records than Zhou Qian, although Hu Ling'er's defense at the time was very convincing, but she did not deliberately use this as an excuse to get rid of the possibility of suspicion.

However, Principal Lan and several teachers from the Political and Educational Office watched the surveillance back and forth several times, but nothing came of it.

Zhou Qian came early, handed in his homework relatively early, and put his homework on the podium in different categories, and then sat in his position to fight with copper sulfate, and never went to the podium since, so the suspicion can be basically ruled out.

Hu Ling'er also went early, probably the fourth person in the class to walk into the classroom, and after she went, she put her homework on the podium and finished it, except for her who went up to hold the exercise book at the end, she didn't pass the podium in the middle.

The only suspicious point is:

Later, people entered the classroom one after another, and the class ushered in the peak of handing in homework, and when the National Day holiday returned, there were many homework in various subjects, and a group of people gathered around the podium to block the monitoring, which was probably the best time to start.

Principal Lan pressed the corner of his forehead with a headache, he didn't think that the children's dislike of a teacher could reach such a point.

If this murderer is not caught, I am afraid that no teacher will dare to come to Qingxi High School in the future.

But now, the surveillance can't find any clues, and the people in the class don't admit it, what can he do

Principal Lan thought about it, and finally used the time of dinner in the afternoon to find Su Nan to talk.

When Su Nan arrived, Principal Lan was still pondering in front of the monitor.

"Senior brother."

Principal Lan came back to his senses and beckoned to Su Nan

"The man came here to see, can you see anything from this surveillance"

Su Nan was slightly surprised.

It is very rare that she can be found to prove that her wise and martial senior brother has not found anything.

Su Nan brought a stool, sat next to Principal Lan, and looked at the surveillance carefully.

At the same time, the school cafeteria on the other side.

The story of the fifth class of the second year of high school scaring the teacher to tears has now been widely spread in Qingxi High School, and the other classes unanimously said

It is worthy of the legendary bandit class, look at this style, Nimattee is so terrifying

Shivering.

And the fifth class is relatively indifferent, and after rectifying Deng Xiang, they only feel that they have a bad breath, and they are very refreshed.

But one of the more annoying things is that when the friends on campus see them, the topics are all on the side.

Make it as if they know the truth.

They're also confused, okay?

On a deserted tree-lined path on campus, Song Tingchuan stared at Hu Ling'er in front of him

"You asked me to drag Su Nan just to play a prank"

Hu Ling'er didn't have any expression on her face, "Why can't you?"

Song Tingchuan "Your Purpose"

Hu Ling'er smiled proudly

"She didn't come to class today, isn't my purpose obvious?"

Song Tingchuan frowned

"You're trying to get rid of her"

"Yes, I've thought about it, no matter how much trouble we make, this teacher won't leave, so I can only force her to resign voluntarily."
