"He told me that after adding these special materials to the circuit, they can actually serve as a surveillance tool. It's like having a camera; it can monitor everything in this room in real-time, including all the entries and exits, and all the sounds—everything will be received."
"What did you say? A monitor inside the circuit? This, this doesn't seem realistic, I don't recall such technology existing before."
"It's also the first time I've heard about it, including when I was at the corporation. I never knew about this advanced technology. If that's the case, then these ordinary detectors, including all the detection equipment here, probably won't be able to detect these."
"Then what kind of background do these people have, to be able to create such sophisticated technology?"
