Chiyou was not only a person's name, but also the name of an ancient clan.
All the people of the clan of Chiyou had the bodies of men and the heads of cows. Their skulls were coppers, their foreheads irons, their tendons steels, and their bones irons. Of all the races in the universe, their fleshly bodies were the strongest, and their fighting strength was one of the most amazing. They consumed sand and ores as food, and they were able to extract and absorb the metal essence from these bizarre foods, using them to forge themselves muscles and bones that were countless times tougher than any metal. The strongest of them could not be injured by any weapons, and had the strength to move mountains. They were the most fearsome warriors on the battlefield.
