飞艇为什么消失了

简介：In these stacked and very inconspicuous two-story buildings, on the balcony corridor on the second floor, there are people wandering around with walkie-talkies in their hands from time to time. Every four hours, a vehicle will drive in, and two people wearing brown coats will come down furtively. People in blue jeans, check the situation, and then the vehicle enters the two-story building, and the rolling shutter will be pulled down.
