At exactly 1 a.m., the security room on the first floor of the apartment.
Tonight, Yang Xiao and Mo Daidai were on duty.
Seeing that it was about time, Yang Xiao stood up, ready to patrol. The floors he had chosen to check were the 4th, 5th, and 6th, starting with the 6th floor and then making his way down.
"Do you plan to stop by your room for a look?" Mo Daidai, sitting on the chair, looked at Yang Xiao donning his coat.
"Do you have a problem with that?" Yang Xiao asked.
Mo Daidai suddenly laughed, revealing a merchant-like face, "No objections, but I have a suggestion that you might find useful."
"Does it cost money?"
"Of course, 5 yuan." Mo Daidai smiled.
"Just 2 yuan, or forget it."
"Deal."
