"What's happening to them?" Beck put down his weapon and asked. "It's as if they were summoned."
"It's the Siren King," Amy said in a deep voice.
Whales can produce sounds with frequencies between 15 Hz and 40 Hz, which romantic ocean surveyors call whale songs. They are social animals, conveying information to their group through sounds of varying frequencies, including but not limited to expressing emotions, positioning, monitoring the environment, and hunting prey.
However, human ears cannot capture infrasound below 20 Hz.
Unfortunately, Amy heard the Siren King's whale song, a sound resonating in her ears as if it had penetrating power. Her body underwent subtle changes after being exposed to the polluted rain for an extended time.
Beck suddenly pointed at an advertisement on the nearby utility pole: "It's him!"
