mmhhm! i see! the name is mysterious, usually "Void" is a primordial and ancient term for folklores and myths. Void literally means Vacuum of nothingness. Nothingness has the power to devour all. Power of Zero! 

I feel like there are very few indication of power levels and rankings at book one. i mean like cultivation or levels in RPG. happy to hear that you are rewriting it. A story is akin to piece of iron. the more you refine it the stronger it gets. Best selling stories was never written in a single sitting. they have gone countless refinement or rewriting. I m happy that you are patient enough to think about quality instead of quantity. 

Power levels was an area I had wanted to elaborate on early on, but never really got into due to the fact that a fairly low emphisis wound up being placed on combat. I am going to have to carefully consider what I'm doing with that in the re-write, but I likely won't do it exactly the same as it is right now.
