Fantasy: I have an invincible modifier

Su Chen is transported to a fantasy world, where he becomes a disciple with useless spiritual roots, bullied by nearly everyone in his sect. At his lowest point, he awakens an unlimited modifier that can alter the fate of all things and reshape the rules of the world. From then on, he follows his own will, settles old scores, and moves freely through the world. He advances steadily across realms, using the power of modification to pass through one major world after another, ultimately rising to the pinnacle of all worlds.
