Being Robbed of an Opportunity? I Refined the Entire Demonic Path with My Backhand

They say that the devil is dangerous and destructive of people's minds? Sorry, that's just my nourishment. Being deprived of a heaven-defying opportunity and thrown into the abyss of eternal damnation, Lin Ye should have disappeared and died. But in a desperate situation, he awakened a strange ability - [The Source of All Transformations Demon]! The demonic energy that the immortals regard as a scourge is his growing cultivation; the frightening magic secrets are the source of his skills; the ferocious and cruel demonic giant is the "material" for his progress; the demonic sect that has been passed down for thousands of years is the "branch" under his command! He walks between light and darkness, refining the power of magic and doing his own thing. Zhengdao regards him as a serious problem, and the demon king calls him the lord of all demons. When the war between immortals and demons breaks out again, the whole world is at stake. The immortal genius who had robbed him of the opportunity was calling on the world to kill demons and protect the common people. And Lin Ye, perched on the top of the devil's path, looked down on all living beings. His enemy is the entire righteous path, and behind him is the entire demonic path. But, who said that if you refine the devil's way, you can't... Refine the heaven's way? Let's see how a generation of "Demon Lords" use demons as their basis to conquer the world!
