After walking for a whole day, everyone was very tired. They didn't arrange for anyone to keep watch at night. They directly lay in their sleeping bags to rest and then lit a large bonfire to protect them from the cold and to prevent wild wolves from approaching.
Before going to bed, Tan Rou turned on her satellite surveillance system. Once an extreme weather disaster was detected, the surveillance system would alert the police. This monitoring was mainly for sandstorms. Sandstorms were too dangerous. If they did not deal with them in advance, they could easily lose their lives in the sandstorm.
Tan Rou was very sleepy. She and Zhuang Liu squeezed into the same sleeping bag. Sleeping together could keep them warm and safe. After all, the bonfire was only so big. If everyone wanted to be close to the bonfire, there was not enough space.
