It was already 11:30 noon after leaving the principal's office, and Chen Yao walked into the school cafeteria.

I sniffed, and the air was filled with the fragrance of various foods. I used to hate school foods when I was in school, but now I miss them a little.

After leaving school for so long, I came back again. Did I eat food? I eat emotions.

There was a long queue at the window, and Chen Yao didn't want to line up, just when he was thinking about finding someone to get food for him.

Han Yuxin walked over with a smile and handed a lunch box to his hand: "I'll give you a meal."

This girl who always has dimples on her lips when she smiles, is quite considerate. While she is making food, she also gave Chen Yao a copy.

Chen Yao was not polite to her, so he took the lunch box and found a seat to sit down.

Han Yuxin followed him and sat next to him.

As a college student, she was already tolerant and attention. She also gave food to another boy, which attracted the attention of the boys around her.

"Who is the one wearing sunglasses? Why did Han Yuxin get him food?"

"It is said that the school beauty has a crush on a male god. Could it be him?"

"Damn, my goddess, have you fallen like this?"

Han Yuxin ignored other people's gazes. She just admired her senior brother. As for what others think, she didn't care.

Is there any difference between worshiping someone and liking someone?

Literally speaking, there are differences.

However, if Chen Yao took the initiative, Han Yuxin would not refuse.

At this moment, a boy wearing a white T-shirt walked over with a lunch box and sat opposite Chen Yao.

His name is Cui Weixiong, he is a junior student in the School of Computer Science and Technology of Shenzhen University, and he is in the same class as Han Yuxin.

He has been pursuing Han Yuxin for a long time. From the day she came to college on the first day, he fell in love with her, but he never launched a pursuit offensive.

But today a boy suddenly appeared. She seemed quite close to him, which made Cui Weixiong very unhappy.

"Yu Xin, who is he?" Cui Weixiong asked with a smile on his face and pretended to be relaxed.

Han Yuxin thought about it and said, "Students from our school."

Cui Weixiong guessed that they had something to do, but he didn't ask too much, and ate the meal silently, glanced at Chen Yao from time to time, with a little hostility in his eyes.

After dinner, Chen Yao got up and left the dining table, and came to the faucet to clean.

"I'll wash it for you." Han Yuxin walked over and reached out to hold the lunch box in her hand.

Chen Yao did not refuse her. Han Yuxin held the lunch box in her hand, put it under the faucet and rinsed it with dishwashing detergent.

The eyes of the people around him looked over, what happened to the school beauty today? She was so proactive?

After washing, Han Yuxin went to the bathroom.

At this moment, Cui Weixiong appeared in front of him, and he looked at Chen Yao with a bad face: "What is your relationship with Yu Xin?"

Chen Yao really doesn’t know what his relationship with Han Yuxin is. He has only met twice, so he should be considered a friend, right?

"Guess?" Chen Yao said and bypassed him.

Cui Weixiong warned: "Stay away from her, school beauties of Yuxin's level are not something you can chase after. Otherwise..."

Cui Weixiong held the wooden chopsticks in his hand and broke them with a snap: "You will bear the consequences."

Chen Yao glanced and walked out of the cafeteria. The sun was bright outside, and the soft sunlight shone on his face so comfortable.

"Senior Brother, come to my class." Whether Chen Yao agreed or not, Han Yuxin took the initiative to take his hand and walked towards the class.

School of Computer Science, Grade 3 and 2.

The proportion of girls who learn computers is relatively low, so there are even fewer beauties. There are even more boys who pursue her like dog-haired beauties.

Walking into the classroom, Chen Yao found a back seat and sat down, took out his cell phone and clicked on it.

"Brother Weixiong, you got it. The four of me in my dormitory were robbed together, but they didn't get it."

"It's so hard to grab it. Many people want legendary speakers. There are no stocks online and offline. How did you grab it?"

Chen Yao turned around and saw a group of boys gathered together, and a pair of legendary speakers were placed among them.

"I just bought it from the scalper, and the price is a bit high, 80,000."

Cui Weixiong gently stroked the surface of the speaker with his fingers, turned on the speaker, and then selected a piano dance song, and the music was released.

The speaker instantly turned into two human figures, one man and one woman dancing in hand.

The eyes of the students around him were shiny.

"Play!"

Cui Weixiong patted his palms twice, and he said with excitement: "Now, I will demonstrate this speaker to you and give you some reviews. There are some functions that Mr. Chen didn't have time to finish at the press conference."

He is an audio enthusiast and is very good at speaker equipment. His classmates all want to hear his reviews.

The whole class sat down, Cui Weixiong stood in front of the podium holding a pair of speakers and put down the speakers.

Then, he released a song "Red Bean".

He smiled and said, "The Legendary Speaker also has a very awesome function, which can control the spread range of sound.

What are the benefits of this kind of control of the sound range?

It is like liquid, controlled to play within a range, and will not exceed this range, nor will it affect people outside this range.

For example, if you are listening to music at home, but the sound of your speaker does not want to be transmitted outside the room, and if you are heard or interfered with others, you can turn on the range control function."

The students were surprised that sound can also control the spread range, how is it possible?

Cui Weixiong turned on the speaker, played a song "Beautiful Butterfly", and then set its spread range in the speaker, right in the classroom.

"He Daqiang, can you hear the sound when you go out of the classroom?" Cui Weixiong looked at the boy wearing a red T-shirt.

Immediately, He Daqiang stood up and walked out of the classroom.

A magical feeling appeared!

The songs I heard in class were very loud, at least 60 decibels...

But as soon as I walked out of the classroom, I just left 5 cm. 5 cm, and the sound disappeared immediately.

He turned around and stood at the door of the classroom, put his head into the classroom, and the singing immediately returned.

He was surprised: "It's really amazing to be able to control the sound range!"

Cui Weixiong set it up for a while and controlled the spread range of the sound to 1 meter. "Now, the singing can only be heard within one meter of the speaker."

He Daqiang immediately approached the speaker. Sure enough, within 1 meter, the sound he heard was very loud.

But if you walk 5cm away, the sound will completely disappear.

"Damn, what kind of genius is this?"

Traditional speakers can only achieve the distance that the gradually deteriorate the sound.

But the legendary speakers are divided into two worlds just by 5 cm.

Isn’t sound transmitted through the air? Can legendary speakers actually block sound out of thin air?

Oh my God, this is a partition out of thin air!

Students are very curious, how did it be done?
