Yueyun's home was in a village near the Shennong Nature Reserve, a county far from the city center. There were only two buses to the city each day, and she usually went back in the morning. This time was no exception; the others hadn't returned yet.,Yue Yun walked leisurely, hearing a familiar voice. She immediately turned her head and saw an old man setting up his stall in front of a shop. She sheepishly stuck out her tongue and hurried over, "Grandpa Li, you're here again today","Well, you're talking about that one... Oh, that one, let me think, oh, I remember now. A few days ago when I was out looking for bargains, I got tired and rested on the road. I saw it by the roadside, thought it looked pretty good so I picked it up. These days people love collecting strange rocks, you never know, maybe I could make some money from it."。
