Start with a Little Devil

Short and concise introduction: "It's so beautiful!" Long synopsis: I probably take a girl with me and do things around the world, then change the map and go to an alien planet, maybe to the universe. Secondary version: The intertwining of ancient magic and advanced technology, the confrontation between mysterious ancient civilization and splendid modern civilization. It all starts here. Ps: I really can't think of an introduction, I'll see the content in the book. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
