I have a sword that can kill all enemies in the world.
But, I only have this sword.
Master often says that everyone has a destiny, and there is no way to change what is destined. I know that my destiny is to wield the sword of destiny at the age of 20, and the sword will come out and cut off this mortal world.
Those who are destined have no way to escape, and the sword of destiny cuts down the mortal world.
