I feel slow for only now remembering the "Blessed by the Spirits" part of the title and finally understanding this moment from the previous chapter:
For
this chapter though, I'm curious about the ability to increase one's magic power by exhausting it. According to Ch. 1, their house has produced
excellent mages for
generations, so presumably if anyone would've known about it, her family
definitely would've known. Since they were entirely unaware that they could increase magic power so easily, it's very possible it's not known by many (or
any) people, which would mean her family would end up with
much greater magic power than most.
