A Corporate Drone Building Infrastructure in Another World

I like it very much and am very satisfied. When will the protagonist and his party go to the royal capital to see the little princess? I am looking forward to the plot of the protagonist teaching the little princess. Also, where did Kazuma go? He disappeared after the first few chapters. And the author, if the protagonist can't learn magic, why can't he learn physics? It's okay to forge firearms for the protagonist to use. Even the golem can be made and magic guns can't be made [what]

Not bad, at least it suits my taste. I support it with 5 stars.
