How does 1000 kobolds with 2 gold in one sword, somehow = 4000 gold. You should only be able to get 2000 gold from that and that's if every kobold is droppings sword. This author is kinda tragic at math skills. OMG.
Does converting to earth currency even make sense?
Author (or translator idk) needs a proofreader for math, all the numbers and calculations are a little fucked up.
