Gu Yuan hurriedly checked when was the last time those people had maintenance, and as he flipped to the last page, he finally saw the time record.
"If my previous guess is correct, those people come here once every three months, and it's almost exactly three months since the last time..."
Gu Yuan suddenly lifted his eyelids, with a noticeable excitement in his eyes.
"Looks like my luck is the best, catching some people red-handed as soon as I arrive!"
Muttering to himself, Gu Yuan turned around and put the related booklets back in place, then changed into the staff's clothes.
He even started pretending, picking up a walkie-talkie and wandering around, clearly preparing for waiting for a rabbit to jump into the trap.
Watching as time passed by bit by bit, Gu Yuan wasn't nervous at all.
He patiently took out the food he had swiped from Yun Ran and ate as he walked.
