(Disclaimer: i only read about 300 something chapters)
this novel is meh. It was cool at the beginning, but then it went from a cold mc and his own personal power growth to just army building and nonsense harem most of the time. The power progression of the mc is also absolutely bonkers, he takes forever to make breakthroughs and the requirements to make them are outright ludicrous. what's the point of realms and orders if you can just skip them and kill beyond your order? at first it gave you quite the dopamine rush reading these type of david vs goliath encounters, but then you realize how dumb the power system is. also, never once cared for the whole succubus partner deal, so that was also one of the things that put me off.
