In a room on the thirty-eighth floor of a tall building opposite a villa community, near a window.
There were two people in the room, one of whom was using binoculars to observe the situation outside. Beside this person, there was also a sniper rifle placed.
The other person was lying on a soft bed, buried in sleep.
Although the room was not particularly tidy, it was orderly. On the table in the room was a computer that had already hacked into the building's security department's surveillance equipment via a virus, displaying the situation inside the building.
These two people were evidently seasoned surveillance operators, with strong counter-surveillance capabilities.
The reason they had real-time surveillance footage of the entire building was to prevent being ambushed by others while they were observing others.
