Were there any carbon-based creatures in the world that could directly devour large amounts of metal elements?
The Earth in the 22nd century did not seem to have any.
However, similar records could be found in myths and legends.
Meng Chao remembered that during the Earth Open Day event organized by Blue Home, he had once read several Earth classics that were treasured in the Dragon City library.
On them were records of the Chi You Tribe in ancient times.
It was said that the Chi You Tribe "spoke the beastman language, had copper heads and iron foreheads, and ate sand and stones."
It was also said that Chi You himself "ate iron and stones, had a human body and ox hooves, had four eyes and six hands, had ears and temples that were like swords and halberds, and had horns on his head."
These descriptions were very consistent with the characteristics of the Turan people.
