Xueba God-level system

"This is so terrible." Xie Menglu tightly covered her mouth, trying her best not to cry out.It's all my fault. If I knew it earlier, I sneaked into the classroom and didn't turn on the lights.

The long and narrow figure stood upside down on the window, with the feet on top and the human head on the bottom.Looking back at her first impression, it was a figure standing upside down, and it seemed that it was a boy.

I don't know when, fine sweat had already appeared on her forehead, and her heart was beating non-stop.Breathing quickly, she stared at the ground in front of her, hoping that such a terrifying thing would disappear sooner rather than later.

There are so many horror movies where there are often such scenes. In the dark in the early morning and late at night, there is no one in the quiet campus, only those homeless, lonely and wild ghosts are floating in it.Not only that, many schools used to be cemeteries, and this is their home. It's just that during the day, there are so many people in the school that they are too scared to show up.At night, it was different. There was no one in the school, so of course they occupied it.

The more she thought about it, the more scared she became. Suddenly, Xie Menglu had the urge to cry.Fear is useless, it will only make you more afraid of the unknown.It is absolutely impossible to make yourself bold in a short period of time.What to do, the only thing that can be done now is to "drag" a word, and drag the time with the feared things.As long as I stay for more than two hours, at six o'clock, students will naturally come to the classroom.

Thinking of this, she inexplicably increased her confidence.It's a pity that I don't have a mobile phone around. If I have one, reading online novels can also pass the time.

Forget it, let's memorize my English words.Knowledge is power, as long as I know enough, those monsters and monsters can't get close to me.

As everyone knows, the figure suddenly became smaller, and it became smaller regularly.Not only that, but its color began to change from black to gray at first, and finally disappeared altogether.

After a while, Xie Monroe's words were almost memorized.She poked her head tremblingly from under the table, but was surprised to find that there was nothing on the window. Could it be that I was blinded? I shouldn't have seen it just now.

In the corridor outside the classroom, the sound of footsteps resounded at this time, and the sound of walking was also very fast.Coincidentally, Xie Monroe also heard it, and this thing is slowly approaching my classroom.

The door was suddenly opened by someone, and the gloomy wind was blowing outside the classroom, and the pages of the books on the desk that were scraped were flying like phoenixes.

"Who?" Xie Menglu called tentatively, but what she never thought was that the person who came in was actually Cheng Bite.

"Why are you here? Was it you who knocked on the window just now?"

"Don't mention it, last night I didn't go home at night, I wandered around the campus, and in the end, it seemed like someone knocked me out." Cheng Yaotie didn't dare to lie to the girls, so he could only say one by one: "Wake up. Just lying on the open space next to the toilet, maybe I caught a cold, my head is still a little dizzy."

After seeing that the person who came was a classmate, Xie Menglu also sat with him.The two of them chatted like this, and of course the person who knocked on the window was Cheng Yaotiegan.He didn't have any ill will either, because it was hard for him to believe that there were still people in the classroom so late.

Xie Mengluo and Cheng Yaotie, both of them have been attacked to varying degrees, and the person who attacked them was Liu Xianying.She sucked the IQ factor of the two people, so it makes sense if they can't remember anything.

"Then what happened to the upside-down portrait I saw just now?" I didn't want to ask about it, but I felt curious if I didn't, so I just asked.

"What is an upside-down portrait?" Hearing Xie Menglu say this, the hairs behind Cheng Bite's body stood up immediately.

Could it be that there are other things in this school besides the two of us now?What is that mysterious shadow?

"Ah, I see!" Cheng Bite clapped his head and exclaimed, "There was such a problem in junior high school physics, this is an obvious image of a small hole!"

"What is Xiaokong Imaging, can you eat it?" Cheng Biteie saw the cuteness in Xie Menglu's eyes in an instant, the girl was still too naive.

After a "pop", a chair was kicked to the ground by Cheng Bite, and he took out a pair of glasses from someone else's desk and put them on.

Looking at it this way, it does not look like a learned person, but looks like a professional in the mixed society.But these are not important, his explanation is the most attractive.

To talk about pinhole imaging, it can be traced back to a long, long time ago.About 500 years ago, Chinese scholars - Mo Di (di) (Mozi) and his students made the world's first experiment in which a small hole formed an inverted image. Such a record.

Xie Monroe once thought that the great physical experiments were all researched by foreigners. I didn’t expect that Chinese physical experiments could be advanced for so long, which is really amazing.

Lectures continued, and the final conclusion was that light travels in straight lines in the air.

After the lecture was over, Xie Monroe finally gave him a warm applause.In that case, the upside-down figure on the window is actually caused by the image of the pinhole.

"It's so smart." Cheng Bite touched her cheek, then quickly retracted his hand and smiled awkwardly.

The first ray of sunshine in the early morning shone in the classroom, reflecting on Cheng Bite's face.The student on duty was the first to come in. Seeing this situation, he cleaned up very wisely. Only the two of them were not cleaned, and other areas had already been cleaned.

This is the case every day, and the repetitive mechanical movements have long made the students tire of it.Fortunately, I saw such a different scene this morning, and it could have been used as a discussion point after dinner.

"Hey, did you know, I saw Cheng Bite and Xie Menglu sitting together this morning!"

"That's right, I saw it too. Go to bed after class, maybe you won't be named in class."

"That's right, we thought about it together."

"Who is in the third row in front, talking so loudly, does it really mean that there is no one in the school?" At this moment, the principal came over.

"You two, come out." No one is afraid of the majesty of the principal, sometimes even himself.

The two students were sentenced to clean the toilets because of their morning exercise.It just so happened that they didn't want to go to class either, so they just swept away.

Cheng Bite opened his tired eyes and found that Xie Menglu was by his side.
