Lilith directly switched the listening frequency to 444.4 MHz, then pressed the play button.
The grating sound that had already been extremely unpleasant from outside became even louder. It was like countless rusty iron sheets scraping against each other, mixed with sounds like fingernails scratching a blackboard and knives scraping glass... Just listening to that noise for a few seconds was enough to make anyone intensely irritated. If it played on loop beside someone's ear twenty-four hours a day, even the most patient person would probably go insane.
"These sounds are fucking irritating..." Lilith frowned. "Next, next!"
The three of them quickly listened through every frequency from 111.1 MHz to 999.9 MHz, even trying "special" frequencies like 123.4 MHz and 987.6 MHz.
Unfortunately, only the nine frequencies from 111.1 MHz to 999.9 MHz produced any audio.
After repeatedly comparing the sounds on those nine frequencies, they finally settled on 888.8 MHz—compared with the others, the sound on 888.8 MHz was not necessarily the most normal, but it was definitely the most "comfortable."
This frequency was endlessly looping a piece of classical music—Mozart's "Symphony No. 40 in G minor."
