I recommend the Mythology of Doomsday to you. This was a sci-fi apocalyptic novel. The male protagonist was cold and ruthless, subverting traditional character portrayals. He was independent and survived in the post-apocalyptic crisis of zombies, otherworldlings, cults, and so on. He did not build a base, nor did he form a team. He was alone in facing the challenges brought by evolution. At the same time, he was able to evolve and continuously increase his own strength. He slaughtered all enemies that hindered his evolution along the way and finally became a myth of the end of the world. I hope you like this fairy's recommendation. Muah ~😗
