After taking the Dungeon mission, players need to go underground to find traitors and then kill them. Pay attention to killing all monsters at the task point. If you don't drop it, please walk around, and the last monster will fall into the paint container.

Pick it up and go back to the toilet, then climb onto the roof along the truck on the left, spray paint on all six interactive positions, and then a mechanical policeman runs out of the police station across the street and completes the task according to the plot.
