I only read this chapter to see if it was a good read.
After finding out how d*mb the MC is by using things he got as drops in dungeons before having them appraised I am now glad that I do not follow this story and have no reason to read it.
@Riri:
Sure, the MC is just a dude but when you obtain items in a dungeon - especially as drops - you should not use them in any way before you know what it is.
After all they could be cursed or they could trigger something if not used correctly.
Imagine you do not know about grenades and you get one as a drop in a dungeon.
You would wonder what it is and pull out the safety pin.
Nothing happens cause you still hold the lever down but you don't know that.
So you put it into your backpack.
3-10 seconds later you would be dead.
The MC has no idea what item he had but he simply put something into it.
That could have caused quite some touble to him if it was something like a trap item you would use to hunt monsters or thiefs.
This kind of behaviour from the MC makes him honestly not very favourable as adventurer and even less good for being the MC.
