Chapter 399 An Accident Along the Way (Part [-])
Accident along the way ([-])
Yuyin blushed, and at the same time sighed in her heart.Is this like attracting birds of a feather, or is it that those who are close to ink are black?When her brother was at home, he was so steady, like that...how did he become like that after he came out in such a short time?
She glanced at someone who was pawing at Yue Xi.Turn away silently, can't bear to look any more.

Looking at Mao Yiping again, she couldn't help laughing again. It was really hard for a big man to do such a thing... And at this time, after she solved the problem of why the water is hot, she finally considered Mao Yiping. that question.

Why is there no sound? If it is just this question, it is not very difficult to answer.

"Seventh Brother, I didn't ignore your question, it's just..." It's just that this question hasn't come up in my mind yet.However, it seems a little strange to say such a thing.And she couldn't find a suitable answer, so she just ignored it.

"If you want to know the reason, I can tell you."

Hearing a whoosh, the sweater Pingren rushed over and sat next to Yuyin again.

Yuyin sighed secretly, it really was an act.However, for the sake of his acting so hard...

So, she slowly explained the problems of ultrasound and infrasound in a way that people in this era can understand.Because some proper nouns are not involved, it does not lead to more problems.

However, as soon as her words came out, someone immediately questioned, "So there is actually sister Yu's piano sound, but we can't hear it?"

Yuyin nodded, and secretly praised at the same time, they are indeed smart people, and they make sense as soon as they say it.

And the next question is, "How did Sister Yu do it? How can you make a sound that is beyond the tolerance of the human ear?"

They were all watching Yuyin play the piano before. Although they are not proficient, they are not ignorant of the rhythm. It can still be seen that although Yuyin's piano is special, it still looks like an ordinary person...

Why did it make a sound that ordinary people can't hear?
Everyone looked at Yuyin together, even Yuexi looked at Yuyin curiously.
