not the worst novel, at least the premise is decent, but it's ruined by the arrogance of the mc, and the system making his class partially worse (he has to pay "points" to tattoo anyone, the tattoos are chosen by the system with no regard for the prefernces of the client, also invailidating the artistc skill of the reincarnated person as the system guides him), and for some reason pepole accept permanent slavery for a power boost the mc can delete anytime he wants (why would he even need that apart from being an asshole, he already gets a power boost that makes sure nobody he tattos can overpower and kill him to avoid others gaining such power)
