What food did the ark survive and evolve to eat?
Dragon milk. In the survival and evolution of the ark, dragons cannot be captured and tamed directly, so they can only reproduce by incubating dragon eggs. To steal dragon eggs from the dragon's nest, hatch the stolen dragon eggs by the air conditioner to get dragon cubs, and then defeat the mother dragon to get dragon milk to feed the dragon cubs, which will be used as mounts when they grow up.
