Magic Ascends to the World, I Can Control the Flying Dragon

A young man from modern times is reincarnated into the "World of Oz" and lives a seemingly ordinary and ancient life. Behind it is a world of high-level magic and powerful people and alien races emerging one after another. As a sharecropper's child, he was supposed to stay on the farmland for the rest of his life, but his fate deviated when a lord's steward hired him as a servant and set off to the Emerald Mountain, the meeting place between humans and elves.
