This story is almost interesting in the fact that the MC is so blinded by his own Levelism that he doesn't fucking plan or think about anything.
He's facing a big ass monster with a big ass eye. Stab the eye for fucks sake.
If you can't stab the eye, stab the legs, cutting through tendons so it can't move so much. If you can't stab it at all, briefly retreat and find nearby creatures to stab until you gain more levels for stabby power. But since he was able to cut the wings--when he previously was unable to but suddenly could but if I think about that too long, I'll just end up having a tantrum--he can clearly cut it somewhat.
So, MC, do something, anything, that just may reflect that however long you spent at Level 1 wasn't a complete waste and you learned something from it.
This chapter, overall, accomplishes absolutely fucking nothing.
