A Fool Cultivates Immortality and Becomes a Demon

[Magic cultivation + Decisive killing + Space + Beast control + Insect control] If I become a demon, what will God do to me? The good-for-nothing fool was bullied in every possible way, and everyone regarded him as a good-for-nothing who could be manipulated. No one knows that he has top-level fighting skills hidden in his body and holds the inheritance of the ancient demon king! Having been treated with cold eyes and bruised all over his body, he would rather surrender the world and fall into the devil's path just to protect his only mother. While others have been practicing hard for hundreds of years to seek immortality, he has transformed himself into a demon, stepped on thunder, and crushed all kinds of talented enemies along the way. It doesn't matter if a thousand people point it out, it doesn't matter if it is irreversible! High-energy counterattacks throughout the whole process, constant slaps in the face, and explosive results throughout the process! Watch the weakest fool, step by step, become the number one demon in eternity!
