Xu Huo turned on the ringer of two Communicators, amplified the sound, and stuck one on each side of the room door.
"No need to go to all that trouble," Li Kun pulled out a Door-knocking Prop, "Just stick this on any room door, it'll automatically knock every ten minutes. Even if the Raincoat Cleaner recycles the Props we put out, it doesn't matter. I have plenty."
He proceeded to dump out a bag, "An Artifact Maker who owed me a favor paid his debt with these—all unranked and useless junk. I just left them in my luggage compartment."
"So many, even if the Cleaner collects them one by one, it'll take a while," Xu Huo casually picked one and stuck it behind the door.
"Maybe... If you push them too far, they might break their own rules," Li Kun shrugged, "After all, the instance is their home turf."
