She reached out to wipe her face, but there was already nothing there.
However, Bai Qingqing was struck by an idea—it was the vibration of the sounds that made the rain fall!
Bai Qingqing recalled this nature documentary she once saw on television, which featured a place with a unique topology. She still remembered that the place was at a high elevation and surrounded by mountains. The entire land was shaped like a loudspeaker.
The magical thing was that if people were to stand in the middle and shout loudly several times, very quickly raindrops would start to fall. And after the shouting stopped, the falling rain would also come to a halt.
Of course, that was a remarkable spectacle that came to be due to its unique geographical location; the movements of air currents, etc., were some of the principles behind that phenomenon.
