15th of November, 9:20 pm.
Somewhere in S city, in a shop on the street ...
The rolled-up Curtain Door of the shop had been lowered, but the light in the room was still very bright.
At this time, a slightly fat, slightly balding man was sitting in front of a laptop, looking at the many surveillance images and flowing information on the screen.
On the table in front of him, there were more than a dozen mobile phones and many strange self-made devices. He was wearing a pocket-sized Bluetooth headset in his left ear, and his hands were constantly flying on the keyboard ...
This person ... Was called Dong Feng, which meant East and Feng.
"Dong Feng" was not the name given to him by his parents, but he had stopped using his real name a long time ago. And those who came into contact with him were not interested in his real name ... They only recognized "Dong Feng."
