Chaos Heavenly Emperor

A generation's Demon Lord returns to his youth. In this life, not only does he want to make up for all regrets, but he also wants to defy the heavens, ascend to the pinnacle, and become the master of the world. Comparing cultivation techniques? My casual skill is a Heaven-grade technique; Comparing pills? The pills I refine can bring the dead back to life; Comparing talismans? My talismans can increase power and speed a hundredfold. Don't be arrogant with me, you can't afford it. Don't pretend with me, you can't. And don't mention geniuses in front of me, geniuses are only meant to be crushed by me. In the midst of chaos, I am the Heavenly Emperor, and in the myriad worlds, I alone am supreme.
