Wolf heard him say this and quickly walked over, examining the ventilation duct above. He squinted for a while and also noticed something wrong.
There was supposed to be an iron cover sealing the entrance of the ventilation duct, but now the cover showed signs of having been tampered with; the two screws below were not tightened, and there were also some scratch marks nearby.
And he was very aware that the diagram of the ventilation duct that Joyce had sent showed all four screws properly fastened.
"Should we notify the police or New Moon Hall?" Jiang Shu looked towards Wolf.
Wolf shook his head, "Let's not notify them yet; we're not clear about the actual situation. It wouldn't be good to startle the snake."
"But..." Jiang Shu pointed in a direction, "there's surveillance there. The Deception Group might have already spotted us."
"Uh..." Wolf was somewhat embarrassed, "Okay, I'll inform the police to arrange a surround."
