The new wind was like a knife, blowing across the rammed earth walls of Fushi City, picking up fine yellow dust and hitting Fusu's young and pale face at the crenellation. He wrapped himself tightly in the thick black lamb fur, and his knuckles turned slightly white from gripping the cold wall tiles with force. Outside the city, the Wuding River meanders like a frozen gray snake, and further away is the vast undulating loess plateau covered with the first snow, extending to the horizon that is difficult to see, where is the Yinshan Mountain where the Xiongnu haunted.
