"I can't see anything!"
Brother Peter: "Of course, this device can hear much further than it can see! The problem is that sound takes time to travel, and the terrain might distort it.

He walked around the sound array, pointing at the wire and asking, "What's this wire for, a sound amplifier?"
"No, it's for the base motor." Peter pointed to his own ears, "The recognition of sound relies on my blessed ears."
Wang Zhong: "Oh. I thought Prayer Hands, Hymn Monks, and the like were all sisters—I mean, girls, ladies."
He changed his terms three times before landing on a more formal address.
