The Witcher World

Reborn into the world of the witcher as an peasant orphan our protagonist does his best to survive with only a single book to his name and being just an ordinary human how will he make his way through this world? MC will not be a witcher as that is too clichéd but nobody said he can't be powerful. Almost forgot that I won't do some shitty harem or basic romance. This will be based on the games since it is what most witcher fans are most exposed to. Writing this in my free time.
