Conversion

"My Inheritance have ability call Conversion, through which I could convert my Inheritance Energy into any energy." It said. 

As I heard it, an expression of shock appeared on my face; this ability is crazy, and if it is going to what I think it will do, then I am fucked, really fucked.

"You are right; I am going to cover my Inheritance Energy into pure physical energy." It said as I had guessed. Since it's powerful inheritance energy is not working against me, it might as well convert it and beat the shit out of me.

As it finished speaking, I felt its aura rise to an unbelievable degree, and muscle on its body started to grow; it became the most muscled Grimm Monster Ive ever seen.

Its muscles increased so much that its height has increased by one meter, and it became a red giant. It looked like someone had pumped a tankful of steroids inside it give it such heavy muscles.
