A generation of demon lords returns to his youth. In this life, he will not only make up for all his regrets but also defy the heavens, ascend to the peak, and become the master of the world. Compared to cultivation techniques? I can casually create Heaven-rank techniques. Compared to pills? The pills I refine can bring the dead back to life. Compared to talismans? My talismans can increase strength and speed by a hundredfold. Don't act arrogant with me; you can't afford to. Don't try to deceive me; you can't. And don't mention geniuses in front of me; geniuses will only be crushed by me. In the chaos, I am the Heavenly Emperor; in the vast world, I alone stand supreme.
