Traveling with a Space Station

A seemingly ordinary continent, where people still lived and worked in a farming civilization, but the sudden appearance of a space station that stretched across the sky broke everything. In their eyes, not only were the things flowing out of the mysterious building somewhat magical, but even the continent they had been living on seemed a little abnormal. A certain protagonist: Since you are going to live here forever, you don't mind letting me add more color to this world, right? There seems to be something wrong, the added color is beyond my expectation. But that's not a problem, so just let yourself go more freely.
