, I can recommend a novel called Heavy Metal Shell, which is also a sci-fi novel about ancient martial arts mecha written by Dog Butcher. Although it wasn't exactly the same as Yin Emperor or Ghostly Aura, it still had the thrill of blood boiling and the shocking scenes of hardcore fighting. The protagonist was a young man who was regarded as a good-for-nothing, but he had a tenacious mentality. Even after obtaining the mecha, he could become a god-like existence. I recommend it to my friends who like hardcore fighting and hot-blooded feelings! I hope you like this fairy's recommendation. Muah ~😗
