Like the title says I’m looking for a novel where the MC is some type of beast. Or is of some sort of relationship to a beast. Should be based in a cultivation setting. No harem if possible but if the story is good enough I’ll stomach it. Example would be Invincible Divine Dragon
Is it ok if he is a desendant of a beast ? Like him and his clan can transform to a "monster" form . If yes then Coiling Dragon
Not a novel from NU, but “A Imp’s Virtue” mostly fit your request, except for one point: it’s not cultivation but level up system.
You’re right. for OP, make a “fast” search on google to find this “novel”. I don’t know if the site i read is official or not, as this novel isn’t listed in NU, thus for caution i will avoid to state any site.
