It's a bit foggy. Zhang Linhan felt that he couldn't see clearly in the distance. He always thought it was a good opportunity to go out on a mission this time. But waiting made him feel a little bored. Zhang Linhan was sitting behind a pile of dirt, silently counting sixty times, and then stretched out his head to look into the valley. The valley was not deep, and his hiding place made it easy to observe the dirt road in the valley below. At first he could clearly see a strange rock five hundred steps away, but then it got a little foggy and the strange rock gradually became blurry.
