"Damn, I never thought that if they couldn't get all of this, they would actively destroy it. It seems we're still a step too late."
"I had thought before that they might destroy it, but I didn't expect them to act so quickly. If that's the case, we seem to have no better choice now. We must do everything we can as fast as possible."
"So tell me, what can we do now?"
"They must have received some instructions here at the time. If that's the case, there might be some residual radio signals in the air. We just need to follow these signals; I believe we should be able to capture their specific frequency."
"What? How much time has passed already? Even if there were radio waves passing through, would they still exist nearby at this time?"
"Under normal circumstances, they definitely wouldn't appear in the air. Generally, after transmitting signals in the air, they disappear completely after about five minutes. But did you notice that over there?"
