But, he did realize that he could level up his skills and strengthen his body by using copper coins. It could save him 99.99% of training. It wasn't even hard for him to jump a few ranks in one day.

Not even sure who 'I' really am at this point since Bell's memories are definitely clearer than 'mine'... But I guess we're doing this. Hopefully I've got some useful cheats. Maybe?
