@Patware Yes and no. Foreigners are people who had a body made for them by a greater god of time and space apparently. They can apparently feel each other theoretically due to the blessing of said god they have on themselves.
He doesn't have that god's blessing. He has the 'Great God of Origin and Demise's blessing....among a slew of demigod blessings. So while he functions like a foreigner he got stuffed into a goblin body instead and had no inherit isekai blessing as far as he knew.(Though at the end of this chapter he's realized that he did pick up SOME form of bonus with his ESP power getting upgraded)
@daywithoutgames The old man wasn't defenseless, he couldn't defend HIMSELF but he had the best of the best around to protect him probably even including that hero watching Aporou to defend his ass. It just wasn't enough because while the world isn't set to extremely easy he has already broken it over his knee largely after getting past the barriers that DID nearly kill him already......which is ALSO why an earlier comment of yours is wrong actually. He can't just get skills from anything, due to the way he levels up in this world he is getting fewer and fewer skills over time since he can only get them from suitably strong items, materials, and creatures. Past his goblin stage there was never really a chance that he'd be picking up a skill from anything that wasn't leveling up like farm animals and he already got EVERY skill he could get from the animals in his home area where the majority of his food would come from. He also seems to have a tendency to eat as much of his targets as possible quickly no doubt due to his thoughts that he can only get it within 12 hours of killing the target, in this case likely believing the wyvern was too weak to learn from since he didn't get anything during his arena bbq and then eating the meat later he realizes that he's broken that 12 hour time limit in the past once and again now so he needs to test things.
@PyroclasticFlow For all intents and purposes he never kept mind controlled slaves. What he DID do however was pump aphrodisiacs into their air and leave them there until they wanted sleep with goblins just to actually do it at all. Still evil, different kind though.
I would disagree with your last line though, he has so far shown that he doesn't have any intention of eating his fellow monster companions or wives and definitely not his children. He has a moral code its just WAY more loose then most peoples. The moment they step away from being companions or family into enemies though all bets are off. If his best friend Kichi proved himself to be a ACTUAL enemy not friendly rival then he would kill him on the spot and eat him as an example to his enemies while also growing immensely stronger.
So at minimum I'd put him at having 3-4 categories; 1. To be eaten. 2. To be eaten when he is capable and has the opportunity(heroes mostly). 3. Not worth eating(no skills, or cause too much trouble) 4. Personally Valuable(Friends, subordinates, Family, and those with things they offer him that are more valuable then their meat like the princess and elf leader.)
I wouldn't put it past him to eat people from all four categories if it becomes personally necessary to him.....but they would likely be eaten with a priority of something like 2, 1, 3, 4. Just this chapter in fact he ate someone who'd generally be in category 3 just because he wanted to shake things up so he has a chance at eating a category 2.
