You're missing the point, the reason why there's no tecnology when magic exist that makes it easier for their errin life, which same goes for tecnology in our world, that being said , there aren't many reason to do so research on tecnology in errin world.
The guns existed long and were hidden until that day, they were meant for giants who don't excel magic. when they were found it and it went viral, that's how it became common for everyone, atleast that's how i think. i don't know much about the lore of ancient elves/giant in mabinogi though.

No, I didn't miss any points, in fact, you missed my point in the last post. Magic would accelerate technological advancements, along with magic itself in the real world. Also, you adding in what you think might've happened with the guns doesn't=what really happened. Just because a new avenue of possible research is available doesn't mean something else will just be thrown to the wayside. According to your logic-if that were true, once planes were invented either guns or tanks or something of prominence would've been cast to the wayside to make room- but it just doesn't work like that. Magic would've evolved beside regular science, not instead of it. Besides, if magic was the only thing that was focused on then Errin's advancement is even worse, because a lackluster handful of spells were learned over the course of 220k years. Compare that to us in that same time frame, and there's much to be desired if we're talking just magic compared to regular tech.
Also, the only magic that makes Errin life easier is arguably healing and party healing, but that can easily be replaced by HP potions and bandages. Other than that, all possible known spells are either offensive or defensive in nature; not something a normal person would use in their daily life. That, and the fact that magic in Errin is something that is exclusive to nobility and scholars-aside from Cor that is. So unless there's some secret where everyone in Errin knows healing (spoiler, very few know it), magic hasn't made anyone's lives easier. There's also no telekinesis, no repair spells, etc. something that'd really help the daily life of a normal person.
Alchemy is honestly the only thing that helps in the way of progression. The ability to construct things out of a crystal is very useful- though mostly for construction purposes in a non-combat situation. However, it kind of stumbles on itself in the fact that you need raw materials to make the exact same thing you're going to be using to build stuff with. So instead of wasting all that time and resources... why not cut out the middleman and just take those raw materials and build it by hand and tool?
Let's just face it, Errin just progresses insanely slower than we do here on Earth, magic and alchemy or not.
