I recommend the following science fiction novels to you: 1. The protagonist has the help of the system and becomes the strongest martial artist in many worlds. 2. "National Mobilisation: Reborn Before the Extinction of Mankind": It was about the desperate survival of mankind in the face of alien invasion. The scenes were realistic and the details were rigorous. 3. "Space-Time Safe": A hard science fiction novel about adventures in parallel time and space. The main characters are Sun Wukong, who never bows his head, and Pangu, who created the world. The storyline is very interesting. I hope you like this fairy's recommendation. Muah ~😗
