"You mean to say, the people controlled underground here, whether they enter and exit this place, and because of this, Huang Guosheng wouldn't let them replace the 1st-floor lobby cameras, right? That way, everything could be done without anyone noticing?"
"No, if I were Huang Guosheng, I wouldn't choose to let them walk through the lobby so conspicuously. So, they definitely wouldn't use this route."
"Then if not from here, could there be other exits?"
"It's hard to say. Moreover, I'll tell you, these buildings should have had backdoors set up from the moment they were constructed. It's just that we aren't very clear about the basic situation of how these buildings were distributed here initially."
"Right, I was also thinking about something just now. If there really is a massive underground space on the -2 or -3 level, then, was it excavated later, or was it originally existing here?"
