πI recommend the following sci-fi novels to you. There are many good sci-fi books besides the three-body problem: 1. "Iron Core": This book is a legend about light and darkness. It tells the story of a man who forged a sword with iron and blood and paved his journey with bones. It's a hardcore sci-fi and super exciting. It's worth reading! 2. "Book of Technology": This book tells the story of a person who created black technology after obtaining the technology of an unknown civilization. It includes bio-robots, artificial intelligence, quantum mechanical transmission, supercomputers, plasma thrusters, and so on. It's very interesting. 3. "The King of Chinese Entertainment Science Fictions": This book is an urban science fiction novel. The protagonist transmigrated to another plane and added sci-fi elements to the film production, including sci-fi classics such as "The Three-Body Problem" and "Ball Lightning." I hope my recommendation can help you find a science fiction novel that you like. If you like it, remember to tell me. Muah ~
