I know it's been a while since I had last read this series, but I don't remember it being this poorly written? I do recall this being pretty blatant isekai power fantasy slop, but was it always this bad?
Page 5: Guy delivers letter with an arrow
Page 6: MC goes "huh, that guy delivered a letter with an arrow"
Page 8: Bandit at the front gate asks "did you deliver the arrow letter" and Guy responds "yeah I delivered the arrow letter"
Page 10: MC thinks "that letter must be for the magic stone purchasing rights"
Page 15: Bandit tells Evil Noble "we delivered the arrow letter" and Evil Noble says "Soon I will get the magic stone purchasing rights I demanded in that arrow letter"
Not counting Page 1 being from the translator, this chunk of a chapter was only 15 pages long and yet repeated the same few points so many times... And they weren't even all that important! Who cares that the ransom letter was specifically delivered with an arrow? What's the point of having the MC speculate about the letter's contents if we immediately get the same answer from spying on Evil Noble and Bandit anyways?
