This is THE DUMBEST writing I've read in a while. Why in the ever loving God would he accept to such a stupid and pointless duel when THE WHOLE GOAL IS TO AVOID WORK? And giving 100k DP to a 100+ year old dungeon veteran versus a noob who hasn't even done it for a year is crazy. He has very little chance of winning.
The only way he could win is if he could somehow efficiently summon heavy calibre guns and warheads / bunker buster bombs.
This writer is forcing a dumb battle scenario on a manga that was supposed to be about survival and doing as little as possible aka min/max the system.
@Naruto031 It's pedophilia, grooming, lolicon and molestation. Not to mention hes allowing it in return for favors, so borderline low key prostitution. But it's ok cuz it's her 100+ year old "sister". If it was an ugly old man people would be freaking out but somehow if you're a hot young looking girl it's ok to groom an molest a child.
Also the MC let the sister core molest/rape his dungeon core who's got an underage body and is underage mentally. It's pedophilia but people commenting here are somehow excited for grooming, pedophilia and molestation? I guess people are buying into the "it's okay if it's a girl" rape thing.
