With the equipment provided by Qian Xuan, Liu Zhizhong detected, and amidst his thoughts, he felt a chill, somewhat cold.
It turns out that in his meticulously arranged room, under the master bedroom's bed, under the sofa, in the bathroom, study, tea room balcony, and the exclusive gym next to the study, there were a total of twelve surveillance devices.
These devices were installed in a very secretive manner, and they were also quite advanced and ruthless, with body and voice sensors. They would only activate for surveillance when they detected infrared from a human body or human voices. Once these external conditions disappeared, they would go into sleep mode.
Because on the display screen of the detection equipment, some of the red dots representing the targets only appeared when Liu Zhizhong was within 2 meters of them, and disappeared when he walked away.
"Playing! Playing tricks! Playing me?"
Liu Zhizhong muttered inwardly, not daring to speak aloud.
