"I really can't hear it."
"That's really strange. Let's see what big brother has to say about it later. Don't panic. If something like this can happen, there must be a reason for it. And maybe this reason can be clearly explained, or maybe it can't be clearly explained."
Hei Lang didn't understand at all what was happening, so he kept saying these ambiguous things.
"Now, I think I understand what's going on."
Lin Yi suddenly stopped, then looked up at the two of them and said meaningfully.
"Big brother, what do you mean? Did you think of something?"
"Now, I just thought of a reason. And this is the only reason that can really explain it. That is to say, the pattern of sound waves when she speaks is not on the same frequency as when a man speaks. Moreover, this frequency cannot propagate in this space, so the hunter's words can't be heard by Ling'er."
"I still don't quite understand."
