These past couple chapters have made me a bit confused. If this chick could control dragons like this. Why have they been bothering to use the twins as a source of experience up until now? I mean I know that they also wanted to vent their... "Frustrations" ... and find other ways to exploit them, such as cloning. But if this is anything to go by. They could've just used the Witch to charm all the monsters and kill them off easily. Couldn't she have also just charmed the twins? She could've forced them to level up, then continue using them as a EXP bag. I mean we can already tell they weren't the brightest. But I think anyone would've been able to see the opportunity. Even their boss only realized how much of a EXP Bag the twins were now that they leveled up. You're telling me they've never thought of that? Pretty damn dumb. And With charm magic, we can already predict the typical plot of his sister getting charmed by the witch because she's been pretty damn useless up until now, only serving as the damsel in destress.
And another thing, the summery states that the siblings kill each other in order to level up. However they haven't really ceased the opportunity either. I mean they killed each other in order to be Just strong enough to escape. But after all this time of leveling up, I think they should really bite the bullet and continue killing each other in order to reach a high enough level. I'm sure after a couple days, weeks, or months they can immediately catch up to the blue haired asshole.
