My cultivation techniques can be infinitely fused.

When Lu Zheng awakens in a strange new world, he finds himself abandoned by fortune. With his mother long dead and his father remarrying and forgetting his first family, Lu Zheng watches as his half-brother steals his place in the academy. Exiled to the desolate border army, he expects a life of obscurity and hardship. Instead, his military convoy is swept into a shadowy war between the imperial court and the sprawling martial arts underworld, forcing him into the ranks of the Hundred Cavalry Commandery—a secretive unit tasked with policing the very soldiers he once marched beside. Yet Lu Zheng carries a hidden ace: a mysterious system that rewards his cultivation efforts with experience points, allowing him to fuse and refine techniques without limit. What begins as the humble "Eight Forms of Breaking the Edge" gradually evolves into the devastating "Dragon Elephant Body Forging Blade," each integration pushing his power beyond mortal boundaries. Years pass as the Great Xia Dynasty crumbles into infighting, the remnants of the Hundred Sects rise to carve up the land, and the imperial court splinters into warring factions. But when chaos finally swallows the realm, Lu Zheng—now the formidable commander of the Hundred Cavalry—unsheathes his Sky-Patrolling Blade, revealing that the outcast soldier has become the final arbiter of a dying empire's fate.
