Klaus walked out of the building with a lot of thoughts running through his mind.
"If one basic feral beast core can be exchanged for 50 zitcoins. How come I only got very little from what I had given that hunter to sell for me? Or is it just the school's exchange price?"
It was normal for him to think that way. Feeling he had been cheated made him angry initially but given the situations surrounding the event, he knew the basis of his conviction might not be so true after all.
Even taking out the issue of disparity between the school market system for beast core and the outside world, a significant factor appeared to may have been the reason he had gotten very little out of the thirty basic feral crystals he had given to the hunter to sell.
