Surveillance Room
He Ao lowered his gaze, watching the surveillance in front of him.
The camera was aimed at an elderly man who seemed amiable, situated in a clean and tidy metal 'detention room'.
At first, he was sitting on the bed, seemingly dozing.
As the timeline progressed, he suddenly opened his eyes and sat up from the bed.
Then he went to the door and knocked on it gently.
No sound came from outside the room.
Then he opened the communicator next to him, entered a series of passwords, and with a soft click, the door opened naturally.
He Ao turned his gaze to another surveillance screen nearby.
On the screen, the elderly man naturally opened the door and walked out of the room, while outside, the guard stationed at the door turned his head to chat with another guard in the distance.
The elderly man turned his back to the guard at the door, using the guard's burly body to shield himself, quickly slipping into the corner behind the guard.
