Soon they saw the surveillance camera installed outside the Si Family's corridor. After adjusting the time, a man wearing "Chou Tuan" delivery service uniform appeared on the screen.
The man was slightly thin, wearing a matching hat with the uniform, with the brim pulled down very low, just as Si Nannan had described, indeed making it difficult to discern his face.
When he arrived at the front door of the Si Family, he hardly paused and immediately knocked on the door.
Shortly after, he seemed to be talking with someone inside, and then Si Nannan opened the door, peeked out her head, exchanged a few words with the delivery guy, and took the pizza box from his hands.
After receiving the delivery, Si Nannan quickly closed the door.
The man immediately turned and left, but as he was about to exit the corridor, he turned back to glance in the Si Family's direction.
