You take gold in exchange for executing orders to construct a buzzer. You are a small bell maker and someone orders you to make one into a buzzer in exchange for some gold. This is how you make a living.
Finally the buzzer is done. You’ve earned your gold. You test the buzzer and it goes ring (りん)! Ring! Ring! Ring! Ring ring ring ring ring! Man, that ringing is annoying but hey, that’s what buzzers do.
