the lack of common sense is getting to me. too many stupid and vain old people. an attractive rich girl is forced to become a mistress? not only that, she has no friends to drink with? in order to teach old people to ”control” their strength, he gives them the impossible task of chopping bamboo that’s too hard for them to leave a mark on? HOW does that help. why doesn’t he show them how much damage they can do to normal items, so that they become more careful in real life? teaching people blacksmithing, he hammers iron ore into… nothing? then tries to trick his students???why is this author SO stupid.
