Cadence Chang and the Starlight Conclave Chapter 27

The junior has just gained enlightenment and is quite puzzled when he hears people say things like "People like you should be dealt with by the cleaning brigade" and "I curse you to be found by the cleaning brigade". What kind of allusion is this? What does the cleaning team do, sweep the streets?

1l: Sweep the streets... You are so sweet, fellow Taoist. Although everyone has a broom, they will never sweep the streets!

2l: I came in just to yell: Use the devil-killing stick to beat my male god! ! !

3l: I’m in a good mood today. Let’s teach the children about this ancient and strange story. The specific time when the cleaning brigade appeared is unknown. After all, it was the prehistoric era, but various sources of evidence suggest that it was probably a period before the Lich War and after the establishment of the Heavenly Court. They often appear in groups, ranging from dozens to thousands. Everyone is hidden under a black robe and holding a broom-shaped magic weapon--that's why they are nicknamed the Cleaning Brigade.

It's impossible to tell who is who from their appearance, and it's impossible to know their true identity. Over time, people have distinguished themselves by their broom names. They appear from time to time and at fixed points. They fight in groups with no specific targets. Their cultivation is extremely high. They never seize treasures. They only have one purpose, beating... But they haven't appeared for a long time. They are legendary figures.
