I understand that feeling. But that situation itself will be vital to one of the key points in the plot of the story. Thank you for reviewing this key point though!

And to answer your questions about firearms, yes. It's quite likely that he would make them starting with vehicles. However, spoiler alert, there might be some Kingdom that is already working on them.

Yes! Thank you for noticing that! Not every genius would be a genius in all categories!

Yes! Well, if I can say so. Businessman usually does not have experience in military stuff. However, although the MC is knowledgeable at certain things, he might come as idiotic in some aspects and I acknowledge that as the writer! But to consider your question about the military and technological advancements, in the later chapters, the MC will have hints about his plans that are prepared for the future. Executing his ideas and military preparations early on will not be a very good idea as the others might get suspicious of a city's sudden growth out of nowhere. He is aware that his military power is weak right now but with his incompetent yet sufficient use of magic, he can solve physical problems with his trusty servants.

OH NO AHAHAHA. My bad! I'll update it!

Still in the works!

But considering your idea of auxiliary tools, that can happen!

That's why those higher tiers can fly because of their increased proficiency with magic, where they can cast more than one at a time!

You do have a point! But most mages can't cast multiple magic there. They'd have to cancel flight to concentrate to chant another magic.

Oh thank you!
