A wild guess
Tonight, everyone was exceptionally serious while performing their sentry duties. Of course, the members of this group with their own motives would only start working together in the face of a common danger.
After all, everyone's goal was to get to the Sacred Mountains so they could stir up trouble, so they had better not die before they got there.
Over a dozen campfires were burning brightly in the campsite. Before going to bed, Luo Lan had led everyone to collect enough firewood to last throughout the night. Fortunately, it was winter right now, so firewood could be found everywhere on the ground.
There were nine sentry posts in total, and each of them was manned by two people. All of the trees around the sentry posts had been chopped down to ensure the sentries could have a broad view of their surroundings.
