The autumn wind blows withered leaves by the Jingshui Pavilion, and a fifteen-year-old boy sits on a rock and counts the days - next year the First Emperor will die in the Dune Change, Hu Hai will ascend the throne and Fusu will die tragically, and the Qin Dynasty will fall apart two years later. After traveling through ten years, I signed in to save a family that smelted iron, cooked salt, and stocked up food. Today, my biological father promised to return. The road was filled with yellow sand, and an old carriage ran over the rough road. There were intermittent coughs in the carriage. I patted the hem of my clothes and stood up. The bright yellow car curtain in the distance was lifted by the wind. Cheap dad finally showed up.
