Su Jieyi was first startled, then immediately realized what Bai Yanliang meant.
Indeed... is it necessary to install nine surveillance cameras on this not-so-large first floor?
"Could it be...?" Su Jieyi felt a chill down her spine.
Bai Yanliang didn't speak; instead, he carefully observed all the cameras.
These semi-circular cameras can rotate, but their rotational angle is not very wide.
What's strange is that although there are nine cameras, from their installation angles, they can't cover every corner.
Interestingly, the coverage angles of the cameras create significant overlap.
It's almost as if... it's intentional to make sure every camera captures those few areas.
Bai Yanliang withdrew his gaze, having formed an idea in his mind.
"Follow me."
Bai Yanliang said, then stepped forward.
Su Jieyi was taken aback for a moment, then quickly followed.
...
In the pitch-black corridor.
Xu Zhifei was moving slowly and cautiously.
