Doesn't seem like much. Seems like one of those "playing house in a fantasy world with OP magic" mangas. I mean, really, in chapter 3 he's already building a hot spring. He doesn't even know anything about the world yet, but the main thing is ofcourse that we need a hot spring *sarkasm:off* ...
It may be used as an introduction to his crafting magic, but out of all the things lacking in a medieval fantasy world, a fan-service hot spring is definitely one of the least useful, I guess.
Oh, here it comes: The generic clumsy trainee-knight girl. I don't have to wait too long for the big-titted elf girl now, I guess *sigh*
Nope. I couldn't take in more than 7 chapters of this stuff ..
