Ok, not bad, but not great either. It doesn't anything too wrong, and there are some things I like here. But it also does some things I don't liked, like for example the villains that are just evil for the sake of being evil, he doesn't stay and develop his village, which is a pity because it had all the potential, and the superpower of the protagonist, which is too convenient and I'd prefer if he came with more advanced knowledge, like Roland from Release That Witch. After all these chapters it apparently won't go too far on the tech side, which is a pity.
But I do like the hesitation of the protagonist in introducing gunpowder or other military technologies, the consequences can be bad if it's stolen and Roland of RTW did it without any concern, which I found strange.
It's good, I'll keep seeing it, but with so few releases, I'll just put it On Hold for a year or two and come back later.
EDIT: I took a look at the manga updates, and it looks like the web novel it's based is already finished, and it has 300 chapters. If the adaptation is at the same speed as others I've seen, it should be adapting about 1.5 web novel chapters per manga chapter, so we can expect about 200 chapters until the end. I'd say that if the pace wasn't so fast, it seriously give me the impression he is adapting more than 1.5. I don't know.
