"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?"

"I think it was probably originally existing. If someone really wanted to excavate a new space underground here, the commotion would be too great and likely attract attention. So, they wouldn't take such a risk."

Upon hearing this, Ye Chen just nodded slightly. He felt that Anying's analysis was reasonable and coincidentally aligned with his own thoughts.

"As for this matter, I believe Guo Hongyu, being young, wouldn't understand it. If we really want to figure these things out, we must start from the old master,"

"Right, maybe only he would know what secrets are hidden within this underground structure."

"In that case, I'll go see the old master first thing tomorrow and discuss these matters with him personally."

"Now that we have found these source switches, what should we do next? We can't let these matters keep fermenting, can we?"

"Absolutely not, the first thing we need to change is the red-colored water problem here."

"Red-colored water?"

"Yes. Didn't they tamper with the wiring here? Therefore, I must follow the correct direction in the wiring and change all of this. Eventually, the red-colored water will no longer exist."

"We might need to consult some experts for this. But, you didn't really stump me on this point. There was an expert in this area before. I believe he should be able to help us."

"Good, then I'll leave this matter to you. Also, there's another thing–the whooshing wind sound. If it really is coming from the underground space, is there a way we can stop this noise at its source? That way, such noises should no longer be audible within the building spaces."

"In principle, it should be manageable. As far as I know, there's currently a type of large pressure-reactive testing machine. Using this machine, by conducting a reactive pressure test through the wind control, we can carry this sound away and also push out all the gases at the same time."

"Um, tomorrow I should get a more concrete understanding, and we should resolve this matter as quickly as possible."

"Okay, no problem. So, do we have nothing left to do now?"

"For the time being, it's not as if there's nothing to do. Plus, although we already know everything, those people, will they just stay here indefinitely? Until what time will they stay? Shouldn't we figure all this out?"

"I had luckily placed some infrared detectors in the -1 level earlier; those were supposed to be used for detecting other devices. I didn't expect that they would happen to clarify everything this time."

After saying this, Anying gently tapped a few times on the computer, and soon, the image of the -1 and -2 level parking garage entrances appeared.

At that moment, the locations were completely pitch-dark, which meant that they could only really see everything when a heat source passed through there.

"This, isn't this a camera?"

"It's not a camera. If I immediately set up a camera there, it would be very obvious, and it would also conflict with other digital signals. Hence, the cameras I installed there were quickly discovered."

"So, with just this thermal detector, are you really able to do all this?"

"At least, this method is the most covert. At the very least, I need to know if anyone passes by that place, especially during the dark night, how many people pass by. Currently, detecting all this is possible; we can't do more than this yet."

Actually, after hearing Anying's words, Ye Chen also agreed with this approach because he knew that setting higher expectations now wouldn't be fair since Anying had just joined the company for a day and wasn't familiar with this environment yet.

So, for the time being, this was the only method available.

"So we can't just stay here watching all night, right? Wouldn't that be exhausting?"

"No need. I've set up an alarm system. If anything happens, it will directly pop up an alert message, and then we can just look at the screen."

"Great, I'll also check some senior executives' information over there and figure out who might be arranging this and what significance it might have for them. I need to research this thoroughly."

While talking, Ye Chen stood up and walked over to his desk, casually grabbing all the senior documents in his hands.

"Actually, I don't think there's much to guess. The main suspect here should be Huang Guosheng, right?"

"Huang Guosheng, I actually thought about him earlier, but if it really is him, then perhaps the investigation might be easier. However, if it isn't him, then who could it be? And does Huang Guosheng know about what's happening underneath here or not?"
