MC is supposed to be a "veteran adventurer" but keeps making stupid decision like a 5 year old. MC was warned to not go beyond 3 meter, proceed to think "Eh, what can go wrong?", proceed to go beyond 3 meter, met some kind of disaster, almost died cause he's weak af, BOOM, plot armor. Now, does that look like someone who's supposed to be a veteran adventurer?? Like I get it's a different world, but that shouldn't make you STUPID.
