Sealed Script in Hand: Rise of the World-Ending Demon Lord

Transmigrated as the hero of a cultivation novel, I was ready to conquer—until the system revealed the truth: I'm the villain, destined to be a stepping stone for the protagonist's glory. I fled, hid in a remote village, lived quietly for ten years. Then the righteous hero and heroine slaughtered everyone I knew in the name of justice. Dying in that massacre, I awakened the ancient demon god bloodline sleeping in my veins—the ultimate cheat this world forgot existed. If Heaven's Way wants a villain, I'll give them one they'll never forget.
