"Siren?"
Lu Chuan nodded, "It's a continuous siren, doesn't seem like something's on fire, it's not the kind of siren that passes by. This sound is faint, but it's ongoing."
"Brother Bai, where are the fire stations in our city?"
Old Bai frowned, "There are many, almost twenty or so."
Liu Guodong didn't expect Lu Chuan to actually hear something.
He didn't hear any sirens or explosion-proof hammer sounds just now.
"Are you sure it's a fire engine siren?"
Lu Chuan nodded affirmatively, "It's probably right. The fire engine siren is different from an ambulance or police car."
"Also, this siren isn't changing in distance like a passing fire truck sound accidentally recorded."
"Could it be possible that the location where they're holding Liu Bai is near a fire station?"
This possibility...
"Old Bai, bring the map over!"
"Alright!"
Yang Sen tidied up the table, and Old Bai spread the map.
The fire rescue institutions are similar to the Criminal Investigation Team.
