This is straight up ass, mc gets the blessing on the of the goddess of creation, the highest of all gods yet somehow she is unknown but apparently if the king had seen mc had her blessing, the goddess that is unknown he would had made duke in the spot. so much for the goddess being unknown.
He has life style magic yet somehow he can use "enemy detection" and "holy barrier area" not very life style magic if you ask me, at one point he also said that he had attack magic and healing magic.
There is also the fact that the manga doesnt read well, could be just translation but at the same time going from one page to the next it felt like had skip pages.
Overall i think its just a badly written manga that contradicts it self a few pages down the line.
