I Create Demonic Dao Arts, Humanity Cries Out in Pain

In a high-martial world besieged by countless demonic races, humanity teetered on the brink. Lin Ping'an, an orphan mocked for his abysmal martial talent and consumed by revenge against the cultists who took his family, seemed destined for a pathetic end. But fate had a twisted plan. He awakened the Civilization Master System: a cheat that allowed him to create martial arts and gain power from others cultivating them. His first masterpiece? The \"Pain Demonic Body.\" A technique so brutal, its practitioners screamed in agony, experiencing suffering akin to childbirth for explosive cultivation gains. He released it to the public, under an ironically benevolent alias. To his delight, the pain-addicted masses not only practiced it but, in their madness, began tricking others into this agonizing path. As cries of torment echoed across cities and his own power skyrocketed, Lin Ping'an, the silent architect of suffering, realized humanity’s salvation would come not from heroes, but from a path so twisted, even demons would recoil.
