I should just read this without thinking about the plot. Seriously. This author is f-ing racist as hell. This only makes me look down on Koreans more. Especially so since I rarely see racist fantasy mangas compared to webtoons.
The Japanese guy has a gun, yet he has to trap people to kill them? Even if the sacrificial ladder thing is put into the plot, how would the MC go through it when the people trapped in there didn't die? Makes no sense. The MC also used the relics he stole without even "dominating" them. And also the way he dominates is just to pound the relics... so why the hell do other people even need the social way to get the relics? This is even more true when MC said doing so would harm them. Makes no sense at all.
