In his desperation, Wang Daoyuan thought of the physics knowledge he had learned in his previous life.
After all, he had received higher education. He had studied sound waves in physics from middle school onward, and was still studying them in university, so he was not completely ignorant of sound waves.
It was just that the laws of this world were not entirely the same as those of his previous life. When he was young, he had tried to put the chemistry knowledge from his previous life to use, but without exception, every attempt had failed.
For example, he had once wanted to generate electricity and use it to make lightning talismans. In the end, this world simply could not generate electricity.
In this cultivation world, the principles governing matter seemed to differ somewhat from those of his previous life.
Therefore, he truly had no idea whether the knowledge he had learned in his previous life about weakening sound waves would work in this world. But he had no other option now and could only treat a dead horse as if it were alive.
According to what he had learned in his previous life, sound required a medium to travel.
Such as air and water. But when sound crossed from one medium to another, it lost a great deal of energy. The greater the difference in density between the two media, the more sound energy was lost. With less energy, the sound naturally became quieter.
For instance, if someone was riding a horse in the distance, so far away that the sound carried through the air could no longer be heard at all.
Sound traveled better through the earth. With one's ear pressed to the ground, one could clearly hear hoofbeats, but once the ear left the ground, they could
