Thanks for the chapter!
Wonder if that eye of his can act like an identify skill or if it has limitations? Didn't see anything about the magic knife but it did indicate where the herbs were for him. Hope he didn't just grab everything off a patch and only grabbed a few from each bunch. That way the herbs have a better chance of growing more in that area as opposed to taking it all so will have to go to another area for the herbs in the future. I'm curious if that guide book explained properly how to harvest the herb to increase freshness, decrease damage, and other stuff. Otherwise if the herbs were grabbed by a bunch of muscleheads like the three D ranks who challenged them in front of the guild they'd likely be damaged so only a little if any part of the herb is still useable, mixed with other plants with a similar appearance, and damaged the area preventing or hindering more herbs from growing there.
In any case, would be nice if could find out how Caro became a slave and more about her family. Especially how she ended up with her throat damaged, ears hacked off, and whatever was causing her arms and legs to go numb despite the slave trader's best efforts to treat her. As for Franfilia her interest is probably due to seeing MC pull/put away his gun, knocking out the three in 1 sec with either no residual magic or unusual magic, and either recognizes the gun or that it's OOParts.
