Recently, I've been looking for web novels. I wonder if there are any books that the main character is not invincible, the female character is not a pushover, and the villain is not a retard.

I recommend the book," The World's Struggle in the Other World ", to you. The protagonist in the book was not invincible from the beginning. He was intelligent and resourceful. He would fight for his own interests, but he did not have the ambition to unify the world. The female characters weren't the type who would stick to the protagonist. They each had their own life pursuits and destinies. When paired with the protagonist, there would be more complexity and emotional tension. The villains were not mentally retarded. They were not easily crushed by the protagonist. Instead, they had their own ambitions and goals. Sometimes, they could even work with the protagonist unexpectedly. I hope my recommendations can meet your needs. If you like it, remember to read more chapters.
