It's the Werewolf Vs Vampire thing, much like the Pirates Vs Ninjas thing & the Smooth Vs Chunky peanut butter thing.
Maybe he needs to kill a strong vampire so he isn't racist towards vampires anymore and then we can have the nice vampire waifu.
So the Mc so far has 4 professions, Hunter, Alchemyst, Blacksmith and Mercenary for what it seems, would there be any more professions, and would his mother death play a major point for the future and why he has such a peculiar ability???
MC is wasting time and an opportunity to get filthy rich. All he has to do is to make "Wolf Musk", a new parfum that will make all women follow you until bed. On the other hand, the female Knight certainly will fall for the orc. I mean, Orc and female Knight is a trope, isn't it?
