"Demon Fire" is the first sci-fi story featuring Wesley, and I have started a series of sci-fi stories since then.Now let's rewatch, re-edit, re-delete, and re-order.There is a very interesting phenomenon, that is, we can see that the development of science and technology in the past twenty years has had a great impact on human life. Some "big events" that could be written into novels at that time are now all small things in daily life. . The story was written very long, so it became two volumes.The assumptions made in the book, now it seems, are still very fresh.At the time of creation, it was less than 20 years before the end of World War II, so there was such a story structure. Now, 40 years have passed, and it is naturally "all the past".
