My Martial Arts Upgrade Instantly

Reborn into a cruel world plagued by monstrous demons, Shen Changqing found himself at the lowest rung of the Daqin Town Demon Division, a trainee slayer whose future was a bloody, early grave. Survival meant years of arduous training and constant risk, a path he simply didn't have time for in this chaotic era. Every shadow held a lurking horror, and his own weakness was a death sentence waiting to be delivered. But fate gifted him a secret. A mysterious 'Panel' activated, devouring 'Kill Points' – not from slaying, but from the very aura of contained demon remnants in the dreaded Demon Suppression Prison! With these points, he could instantly perfect any martial art, bypassing years of grueling effort. His first upgrade transformed him from a frail novice into a physical powerhouse, ready to face threats that once terrified him. His ascent was impossibly fast, his strength growing with every chilling patrol. He was becoming a hidden titan in the Division, but in a world where power breeds envy and suspicion, how long could he keep his monstrous, system-fueled growth a secret? And what dark price might his 'Kill Points' truly demand?
