Variation of Figaro. The life of the main character is divided into two worlds, between which he can move quite freely. One World is a slightly alternative variation of the Russian Empire of the early 20th century, where the GG is first a high school student, then a railway student. The other world, which is a Dyson sphere, is truly endless. In it, our Maxim is the owner of the Flying Island. One of countless numbers. Magic in the second world, as you understand, is available. And one more thing, before making your judgment about this book, read at least the first ten chapters, especially since they are still free. There the plot will gradually unfold.
