I obeyed my master's order and entered the world, and married into the family as his son-in-law. Everyone says I am incompetent, but who knows that I am actually a peerless swordsman who looks down on the world? What does it matter to me if I am looked down upon? What does it matter if I am his son-in-law? Just watch me sweep the universe with my sword and break the sky with my strength!
