Can you recommend a good foreign science fiction novel with a plot that is completely out of touch with reality, rather than a tomb raider or an alien?

" I recommend Dark Forest to you. This is Liu Cixin's science fiction novel. It's about the mutual aggression between two civilizations in the universe and the psychological game behind it. It was very exciting, completely out of touch with reality, and it did not involve grave robbers or aliens. I hope you like my recommendation.😗
