Sure, maybe you are right. Actually it's probable you are.
I obviously care too much about such details, considering the mangaka already made it clear during chapter 1 we are in some kind of mystical woo woo land where universal natural laws don't apply. Otherwise MC wouldn't be able to make that impossible cut on that thrown wooden tablet. Impossible not only due to human limitations, but also material properties, conservation of momentum and the fact that the curvature of the the cut was smaller that the blade. So it is likely the mangaka still hasn't figured out the lore of his manga and will probably make up new rules in the future on the spot.
Considering armor in this manga right now has the defensive properties of wet paper machee, the conversation about armor caught me completely off guard and made me write that initial comment. Sure a lot of fantasy stories feature useless armor, but usually they don't mention it. In fact, the only fantasy manga I know of that features functional armor is Goblin Slayer and the spinoff Goblin Slayer first year, where the chainmail is instantly recognizable and works like it's supposed to.
I'm giving this manga another 2-3 chapters to see if it improves. I guess it's not my cup of tea.
