Looking through the comments below, I feel like I am looking at a transcript of a meeting of the ITA (Internet Troll Association), where the member try to out troll one another. Sadly, they all fail.
That's basically the merchant future I was talking about, more specifically selling otherwordly stuff because it's better than other stuff or he can get it way cheaper.
But after doing that for some time, he'll still need some serious protection, which essentially boils down to 3 choices
1. Tamed monsters like Feru and Sui
2. Adventurer bodyguards for longer periods of time or for each travel
3. Permanent bodyguards (could be slaves if slavery is a thing, unconfirmed other than mindslavery tools existing), but would otherwise be someone he's essentially paying a salary to protect him. Could be someone he helped saved with medicine and then repaying the favor with service, could be straight up payment , etc.
@lolmaolol Here you are and complaining again. I thought you dropped this manga. Well, I guess you will just complain on every chapter until the manga end.
