You're trying to open the lid of a manhole that's covered in ice by jackhammering it a bunch of times but it's not working because it's just too cold. It's so cold that your jackhammer is starting to ice up too. But you need to get this lid open so you try time after time after time!
Each time the jackhammer hits the freezing cold ice it makes a high pitched ringing (りん) sound. It's actually really annoying to listen to but you really need to crack this ice open so you have to keep listening to it.
