My Flying Swords are Actually Jet Fighters

Five centuries after the Conferred Gods Tribulation, the once-mighty Jiejiao sect is a crumbling ruin. He Lingyun, a talented crane demoness and sword cultivator, faces a humiliating fate: her shattered flying sword and her sect's extreme poverty mean she’ll soon be hunted for her valuable spiritual body by greedy enemies, or worse, her cultivation will wither. Her only hope? The infamous, seemingly useless Senior Brother Wen Rui. This slovenly drunkard runs a bizarre \"shop\" and offers her a \"new kind of flying sword\"—a sleek, heavy, alien-looking \"iron war eagle\" that defies all cultivation logic. His price? A chilling \"Body Donation Agreement\" for \"scientific research\" upon her death. Can He Lingyun truly trust this eccentric \"mad scientist\" whose bizarre, advanced creations promise unimaginable power, or will she be led down a path to an even more horrifying and unholy fate?
