During the exam he used fireball (beginner level) and the instructor was like, oh my god, firestorm?!
During the herb picking quest he used firestorm (advanced level) girl is shocked and says it isn't normal.
Here he is going, uh oh we're inside a cave, better not use fire magic, oh I know, let's use tempest an advanced level wind spell, no mc you're absolutely right, fire inside cave is dangerous, high pressure wind is good!

@Plank12 it is just author having trouble with his own common sense. I'm surprised some artist picked this up and adapted it into a manga. It's a bit weird though because author's other series have somewhat decent plot and comedy.

they crush rookies because they were crushed by other high rank adventurers? Their thinking is shallow, if one day happens monster stampede,
what will they do with such a small number of adventurers
