In my opinion, "even though I am a newbie?" Is the most unnecessary or dumb answer. The MC is rank 1 in the hunter exam. He had uncountable recruitment offers and hunted a tier 4 monster on his own.
Obviously being a newbie doesn't even matter at that point.maybe the recruiters doesn't even see...
Part of me wanted those survivors to be a good guys but at the same time I kinda want them to be a semi villain. Maybe a bunch of people who want the protection of the army but didn't want to work with them?
I feel a bit disappointed that he faced the boss alone but I guess the others will only be trapped in the quicksand if they follow him. Idk what to feel towards the interaction of the boss monster and the MC though... I'm guessing the giant worm needed food and the humans were simply there...
How to showcase your supernatural ability/ies 101:
1. Say "let me show you" or something similar.
2. Proceed to destroy the table or anything solid in front of everyone.
This is the only system manhwa I've read where the MC is a soldier and the soldiers at least the majority of them aren't useless and is actually have a major part of the plot.
