it reminded me a bit of Lord of Mysteries, lol. I wonder if in the future -if the mc reaches the rank of God, or perhaps superior- will he be able to deceive concepts or even reality as a whole? man that would be just awesome
Do those first two F rank skills really need E rank skills to level up? Is their potential upgrade really that strong? Or was it a mistype on both? Should it be 10, and 20 F rank skills rather than E rank?
