We've barely gotten this novel started and this irrelevant side character is getting way too much face time. The actual MC of this story is the saddest of all. He spends 500 years training in the sword and has broken every romance and adventure flag. Now he's just a glorified baby-sitter with a daughter he picked up that his mistress is raising for him.
even if he were to spend 500 years training, he would not win as our hero has 500 years more experience on him and is 500 years more proficient in ability.
