I recommend two novels to you,"Out of the Cage" and "Return". They were all science fiction novels written by nuclear battleships, discussing the technological, cultural, and social issues of the future world. "Out of the Cage" told the story of the era when humans began to interfere with space and time, while "Return" told the story of humans trying to rebuild the second generation of civilization. I hope you like this fairy's recommendation. Muah ~π
