...
Night.
Room 704.
Lin Fan rubbed his chin, "For people who don't know me, my way of appearing might scare them..."
Thinking carefully.
There might be some noise, but it's unavoidable, that's just how it is when you're going too fast.
"Never mind, better explain it."
He wrote in the original booklet.
[Sounds are produced by friction, the slower the speed, the less friction, so the sound is smaller, but my rescue speed is fast, so the friction is relatively large, and the resulting sound is larger.]
[In the future, after finishing a call with me, don't be nervous if you hear a roaring sound in the sky, that's me coming.]
Looking at the content, he nodded with satisfaction, this was learned in middle school physics, should be easy to understand.
Thinking about what happened during the day.
A bright smile appeared on his face.
"Wu Hao, really impressive."
