When Zan returned, the king was very angry. "You paid five hundred pieces of silver for this?" the king shouted. "What good is it to me? I want a living horse, you fool!"
"Please be patient, my king, "the servant said." When people hear how much you paid for the head of a dead horse, they will think you will pay an enormous(巨大的)amount for a living one! People from other countries will bring their horses to you!"
That's just what happened. Almost immediately, lots of people started bringing their fast horses to the king. The king was delighted, and he soon found exactly the horse he wanted.
