Lu Yuanming forced a grim smile, causing Xun Xiaoyu's eyelid to twitch uncontrollably. However, he didn't punish her but suppressed his anger and said, "I already have a tool to contact someone from that civilization, but the sound this tool emits—listen carefully, it's a sound, a kind of sound wave—is highly toxic. Anyone who hears it will die. So, do you have any way for their people to hear the sound without dying?"
The telekinesis binding Xun Xiaoyu was released. She looked at Lu Yuanming's twisted yet oddly amicable smile and shuddered. This time, she did not dare to joke around. Instead, she began pondering the issue seriously, asking as she thought, "Toxic sound? Is it a metaphor? Or literal toxicity in the physical sense? Something memetic? Just how toxic is it?"
