After office hours, in a corner of the outdoor café in the departure hall of the domestic airport, Luo Zheng and Shi Feng, who had changed into civilian clothes, sat in an inconspicuous corner. Both had done some simple disguising, wearing baseball caps and large sunglasses, making them hard to recognize. They casually chatted, quietly observing their surroundings. With earphones on, the earphone wires plugged into their phones, they appeared to be fashionable youngsters listening to music, but in reality, the earphones continuously reported updates from others.
The airport was meticulously monitored by Shi Feng, with several dozen people covering almost every corner, all disguised as ordinary citizens picking up someone, including both men and women, making them unobtrusive in the airport hall. Even the cleaning staff and security personnel were replaced by detectives from the serious crime unit, ensuring no one could tamper with the high vantage points.
