Ah man, I can only say that, you really didn't read first chapter from this novel then,

You won't know the reason behind it until half of the story.

Zack was transmigrated. And last year he was 16. Old enough to grow hair...

wait what. . sword manship. better say sword with man on the ship.

This is the one only place I spend my power stone, I liked this novel very much and wait for updates every day. I would have given 5 star if the character was not too OP at lowest order. It feels like MC doesn't even need to be reached to the highest level to defeat the End Game Boss, since he can already beat it at low level.
