Is there a good space science fiction novel to recommend?

Recently, there has been a shortage of books. Please recommend a few good sci-fi novels. It would be best if they were hard sci-fi, space war, and the like. I don't want online novels like Qidian. I don't want fakes or small soldiers that I'm too familiar with. If it's online novels, please recommend some that have some meaning. Space war sci-fi like Bastion, Halo, Base, and Andre's Game would be the best, or opera like Silver Hero.
Let me say this again, don't recommend those little novelists like Devour the Starry Sky and those that have serious fantasies.

Answer 1

😋I recommend the following space science fiction novels to you:
1. "Star Sea Insect Tide, Starting from the Milky Way"-Traverse to the world of the Insect Tide, build the Milky Way Great Wall, and defeat the ecosystem predators!
2. [Alchemist's Bastion]-A Bronze Academy student has obtained the legacy of a Legendary Alchemist from another plane. Alchemy and advanced technology collide, and the offensive and defensive effects are not too good!
3. Survival in Space: 100 times drop rate at the start-Falling into space, starting on Hell difficulty? It doesn't matter, you have the 100 times drop rate system!
I hope you like this fairy's recommendation. Muah ~😗
