The vampire’s aren’t really coming across as the big deal that they are being made out to be. I would laugh if the mc has defeated the general and left by the time everyone arrives. Not a fan of low-key behavior, but that would be amusing.
I like it but he has a very large pool of mana now if I were him I would be opening skill gacha every day
and earlier in the story he declined skills
you should leave him with the skills because he may gain a skill merging ability later.
