The gun-slinging cadet underestimated the strength that Jeremy's lightning spear technique held.
After all, a martial technique that was ranked A+ by the martial library would not be a pushover in the slightest.
Every single one of them was a dangerous technique that carried a lot of baggage if one desired to practice it.
Of course, the hard work and effort placed into learning everything there was to learn when it came to such a powerful technique, it would be worth it as the power they held was enough to make several open their mouths wide in awe just by how much power they could exert.
Thus one could say that the gun-slinging cadet messed up badly by thinking of Jeremy's technique as one so easily disturbed.
Though one could also not blame him as due to panic at the thought of getting eliminated just like that, it would not be a surprise that his thinking faculty was a bit stunted.
In any case, back to the situation at hand.
