Minato enraged

Fade sighed as he finished off the last of the pursuers. He didn't expect to have used all of his needles. Though he could use his hair as a medium for [Enhancement], that would've been effective against normal people, but not against martial artists of this level, it wouldn't even be able to penetrate their skin. 

After Fade gained inner energy and practiced with it he learned quite a few things. Those with inner energy have naturally stronger bodies. Unlike with mana were you would need to actively circulate it throughout your body and use a spell to strengthen yourself, inner energy could do that passively. 

When Fade didn't have inner energy, he needed to use his [Enhancement] spell to strengthen himself so that he would be able to do things like jump higher and move faster. Yet now even without using [Enhancement] the inner energy within him has transformed his body. He might look the same on the outside, but his strength had increased drastically.
