Qi Lin thinks it's funny, as long as he takes the initiative to talk to people, people can hear it, isn't there such a saying in the scientific community, the biological frequency of people and ghosts is different, so people can't see ghosts, and the reason why ghosts can see people is because ghosts were human beings in their previous lives, and after becoming ghosts, people's biological frequencies have not been forgotten.

Just like creatures such as bats and dolphins, they can emit ultrasound or infrasound waves that cannot be heard by humans, but it does not mean that there are no such sounds that cannot be accepted by the human ear, not to mention that ultrasound has been invented and used by humans, and modern people cannot refute the existence of ultrasound.

Compared with ghosts, humans cannot effectively prove the existence of ghosts and gods, so most of the humans who grow up in the scientific environment are skeptical.

The reason for this is that on the one hand, the vast majority of people in the world have never seen ghosts, and on the other hand, whether in history or in modern society, there will always be various legends and various supernatural events, and some supernatural events will be affected by a large number of people, which has caused such a mentality of believing and doubting.

Even if there is no ghost that has any ability to harm people, people will be afraid, and a large part of the reason for this is because people see ghosts, just like seeing their own appearance after death, living things are afraid of death, and people are highly intelligent creatures, even more so, these are actually the instinctive manifestations of creatures afraid of death.

If a pig sees the ghost of a pig, will the pig be afraid, the answer is no, because the pig's IQ is not yet able to understand what kind of state the ghost is, and the pig will only be afraid when life is really in danger.

And human thinking is beyond the reach of other creatures, give a little hint, people will imagine a bunch of pictures, you can also say that, people see or hear things that they can't understand, their minds can't stop, there will always be a variety of brain pictures that scare themselves.

And now this little boy, while cleaning the classroom, began to make up all kinds of brain pictures in his mind, he always felt that something was wrong today, since the letter was released, it felt a little strange, a cold feeling has been with him, no matter where he goes, this cool feeling has not been shaken off, the sound he heard before, he always felt that it was not auditory hallucinations, but real.

The little boy's mind unconsciously made up a lot of pictures, nothing more than some ghosts and monsters, although he couldn't see something strange and frightening, but this did not prevent him from thinking wildly, if he knew that there was indeed something here, it is estimated that he would have thrown down the broom and ran away without a trace.

The little boy swept the floor a little absent-mindedly, and his two eyes kept rolling, as if he was on guard against something.

Li Wei ...... Morning. ”

Another boy walked into the classroom and asked the boy who was cleaning up to say hello, it turned out that this boy's name was Li Wei.

Li Wei was startled by the sudden sound, and when he looked up, it turned out to be Zhou Chao, and when he saw that someone was finally coming, the cold feeling seemed to have decreased a lot, and he wanted to complain that he didn't tidy up the broom yesterday, and said a little excitedly: "Zhou Chao...... You're finally here! ”

"Uh...... Why are you so excited, are you...... Is there anything good? Zhou Chao said strangely.

Li Wei smiled: "It's okay, it's okay, it's just that a person feels a little bored, and you just came to talk." ”

"Oh, that's right...... By the way, show me the homework, there are a few questions that I can't do, I have to finish them quickly, otherwise the old witch will definitely be furious. ”

"Oh...... Oh, I'll get it for you, you sit down. ”

Zhou Chao looked at Li Wei blankly, he felt that Li Wei was a little strange today, usually Li Wei was not so good at talking, and asked him to do his homework, and he had to be educated two sentences, how did he feel that Li Wei was begging him to copy his homework today.

Li Wei walked quickly to the desk, took out his homework from his schoolbag, sat down, moved the chair, and was next to Zhou Chao.

"Come on...... Copy it. ”

Zhou Chao felt that Li Wei was really enthusiastic today, and moved to the side quietly, who knew that Li Wei also moved over.

Zhou Chao couldn't help but say, "Brother...... You go and sweep the floor, I'll copy it by myself. ”

"What's wrong, what's wrong?"

"Uh...... How do you ...... Isn't it a bit too ...... That, being seen by others, has a bad impact. ”

Li Wei also felt that something was wrong with this, and he also felt that he was a little nervous today.

"Oh...... Oh...... Okay, if you don't understand anything, you can call me, don't bother. ”

"Got it, got it, go sweep the floor."

Li Wei left Zhou Chao and continued his cleaning business, he felt that after Zhou Chao came, the whole classroom was warmer, the world was much brighter, and he hummed a song while sweeping the floor.

Zhou Chao lowered his head and copied his homework, but gradually, he felt suddenly cold, obviously it was still very warm just now, gradually, he felt that his spirit was a little unfocused.

Neither of the boys saw that there was one more person in the classroom, no...... It should be said that there is an extra ghost.

Qi Lin was a little curious about what he was learning in high school now, so he didn't follow Li Wei anymore, so he sat directly next to Zhou Chao and watched him copy his homework.

"Hey...... You copied the wrong answer to this question. Qi Lin reminded.

"Oh...... yes, I'll take a look, huh...... Thank you. ”

Zhou Chao looked up at his side while thanking, but he ...... What about people?

Zhou Chao looked around suspiciously, only him and Li Wei, where did the third person come from?

Li Wei ...... Did someone just come in? ”

Li Wei turned around and said, "No, what's wrong?" ”

Zhou Chao was puzzled: "Are you sure?" ”

"Sure, I've been here, if someone comes in, I can't see it, unless it's a ghost, and where does this world come from!"

"Ghosts?"

Zhou Chao made up a picture of a ghost sitting next to him, and broke out in a cold sweat, just now he heard a voice reminding him that he had copied the wrong answer, and now the answer has not been changed back, it can't be an auditory hallucination.

Zhou Chao shook his head vigorously, forget it, no matter what, if you can't finish your homework, the old witch is more terrible than a ghost.

Qi Lin didn't speak again, he was afraid that he would really be stupid, and suddenly remembered the letter that Li Wei had put in that drawer before, so he got up and came to the window seat, looked at Li Wei, and was cleaning the corridor outside the classroom.

So I picked up the pink letter and looked at it.

Dear Li Sisi,

I love you!

Only when I know you do I know that there is a feeling called attachment, and there is a feeling called love. It turns out that waiting can also be so beautiful because I love you.

There may be times in your life when you miss someone so much that you just want him to come into your dreams and truly embrace them in your dreams!

You are the best actress in my mind.

I've dreamed of you more than a hundred times, and almost every night your figure comes to my dreams.

……

Qi Lin had already laughed on his back, and he had already gotten carried away, and he didn't notice that Li Wei at the back door of the classroom was looking at this side blankly.

After Li Wei finished cleaning the corridor and entered the classroom through the back door, he saw a pink letter on the seat of the girl he liked, and he recognized that this was the confession letter he wrote to the girl he had a crush, but now he was floating alone in the air, and he shook it from time to time, feeling as if someone was holding the letter, but that person was a person who couldn't be seen, and who was the person who couldn't be seen......

Li Wei recalled the strange feeling before, and finally understood why there was that kind of discomfort, although he didn't want to believe it, but now that he saw it with his own eyes, was it fake?

"Hell......"

Qi Lin froze, and his forehead ...... I forgot that there were still people here, oh no, it scared people, I turned my head to look at Zhou Chao, only to see him staring at this side with wide eyes, a little dazed.

Qi Lin put down the letter in embarrassment and said, "I'm sorry, are you okay?" ”

"What the hell...... Mom...... Save me...... Help me! ”

"Uh...... Well, you might as well just leave silently. ”
