Pretty fun one time only read with some stupid flaws. The dude is 16 years old, even if he doesn't know anything his body would. You make him like he is 7 years old. The MC is all over the place. He doesn't want to obliterate a man with his wind blade but is okay punching through the dude's heart. And on the other hand, he is this emotionless dude. And twice the power is not enough to output that much power to punch through the chest especially if the other guy has higher constitution than him.
