That’s just Im Dal-Young’s style. All the women he draws are unreasonably attractive.
But seriously tho she's hella hot.
If it's percentage based then he's got compounding interest. She ran out of gems to test him so it's at least 50K and probably not just something like 50,070.Given that it seems like he's been chugging them like fucking sports drinks every day since he was a child, conservative estimate is that he's drank ~3000-4000 elixirs in his life so far. I don't think they stated exactly how much one increases your magic power but if he's at over 50K it's probably at least 15-20.
