Oh boy, here come the blacksmithing nerds to argue about how wrong this manga is about blacksmithing. What a surprise. It's a manga yo, get over it and just enjoy the read. It's not meant to be a 1:1 depiction of real life.
Thank you for the translation though, hoping to see more!
I hope someone picks this up and pumps out chapters a bit faster, it's a shame that it hasn't been updated in so long. Loving it so far though, planning on reading Thermae Romae while I wait for new chapters. 😀
