Emperor's Ultimate Spy: Starts as Imperial Guard

Modern youth Lin Xiao transmigrates into a martial arts world and, equipped with a system, begins his comeback journey from a low-ranking Imperial Guard. He solves mysterious cases, saves the Princess, and suppresses chaos in the prefecture, becoming the emperor's sharpest blade through his superhuman strength and modern thinking. From executing orders in Dingzhou to power struggles in the capital, he purges the White Lotus Sect and eliminates the Senluo Hall, maneuvering between the court and the Jianghu. Finally, he uncovers the empire's dark side, conquers the Northern Kingdom, and achieves the realm of the Martial Sage. When the emperor reveals his ambition to unify nine provinces, Lin Xiao, blessed with true dragon destiny, is about to embark on an even more magnificent campaign alongside his lord.
