I feel like trapping prey should be a skill that's cultivated in super primitive society, not just isekai land. It's not as old as the wheel, but surely it can't be that much younger? Am I underestimating the complexity of traps?
Either way, I feel like it would've worked better if we instead said that the Suu are hard to catch with traps, so he needs to devise an entirely new type for catching them. Anyway, wholesome family will support their big brain boy.
Sounds more and more like we need some sort of soldier barracks or dedicated dorms they can keep family in.
