Thousands of Clues

With a handful of black hair, two stupid donkeys, and a pair of rags, Luo Yu, whose family was wiped out, stumbled into the world. The first thing was to learn to survive, and the second thing was to learn to carry three thousand black hair to cut down a mountain and level three rivers. The third thing is to open a grocery store, behave like a little old man, marry a heroine wife, and then sit by the fireside holding his grandson in his arms and bragging to him about his grandfather's bravery back then.
