After walking out of the door, Du Yue sat in the front passenger seat. He Xing turned around and locked the living room door before sitting in the driver's seat. Their house was very close to the door. In less than a minute, their car arrived at the door. Du Yue picked up the walkie-talkie and told Yu Xinya that she and He Xing had arrived. A minute later, someone got out of the car and opened the door.
Yu Xinya said through the walkie-talkie that the person was specially here to guard the door. A car would come over in a while and wait at the closest position to the door. When they came back, the door would open for them immediately. Looking at the people who were struggling to open the door in the sandstorm, Du Yue felt that restoring communication equipment was a very important matter. With communication equipment, there was no need to wait at the door to open and close the door.
