But all of these images have one thing in common, they are all images of Usu every time I turn my head and look at them.

The whole video is about three minutes long, and basically every three or four seconds.

In other words, the whole three minutes are a video of me turning my head, thinking about how long it has been? The start of school has been less than half a month, which is really exaggerated.

"How? Do you feel a little shocked when you look at it? The principal said, taking a cup of coffee and handing it to me.

I turned the tablet off, handed it over, and said, "What does this mean?" ”

The principal smiled and helped me put a piece of candy in the coffee and said, "My mouth is quite hard, is it because I don't have enough data?" Don't worry, I didn't say that there was only one video, and there was more to come. ”

"What's next?" I said puzzled.

What else could there be?

The principal pushed the tablet again and slid it to the next video. I clicked on the tablet, stuffed it in front of me, and said with a smile, "You can continue to look at this." ”

The next video is longer, about ten minutes long.

It's all a zoomed-in picture, and it's probably just me and Usu in the picture.

There were also a few table mates nearby, and I watched the video in front of me.

The content of the video is when Usu is on stage, and there is a red line as the center line of my head where I am located, and there are yellow lines marking the line of sight on both sides.

The entire twelve-minute video is when Usu is moving.

And I followed the lock of the target, as if locked to Usu.

"This device was originally used to supervise cheating in the school's college entrance examination, and of course it was also used to observe the efficiency of teachers. Attendance and student concentration, etc., to see how well you perform. Albert Einstein said.

The picture in front of me embarrassed me, and I turned off the tablet helplessly and said with a wry smile: "That, the principal knows that my studies are important." I'm not going to mess around, headmaster, just let me go. ”

The principal smiled and said, "Let you go?" I'm not going to do anything to you. I'll show you some fun, and you'll see the next video. ”

"How could there be? No, no. I know it's wrong, I'm studying hard and you see how I behave, okay? Don't call parents and don't ask teachers, I swear I'll study hard. I said.

Einstein reached out and turned on his tablet again, swiping back to the next video.

The videos are really longer than the other, and at the moment the video becomes twenty minutes.

Einstein clicked it away and said with a smile: "The protagonist of this video is not you, but your seven good classmates." ”

"Seven? Schoolmate? I said.

The video in front of me is a superimposed combination of seven video frames, and the students in the seven video frames are circled in red, and there is a red dotted line on the head, and the crosshair of the eyes of the red dotted seat is viewed from the yellow dotted seat. From the video they all seem to be doing the same thing as me, with numbers and percentages on the side.

They were all peeking or staring at Usu for a long time, and I looked at the stuff in the video and said, "Headmaster, what is this?" ”

Albert Einstein smiled and said, "Well, these are your potential rivals." I gave them all numbers. From the first to the seventh, and there is their persistence with this oxygen classmate. ”

"Persistence? What does that mean? Principal, what are you studying every day? I said.
