Synopsis:

What is a King?
A King is more than just a generation or a class. They are known as Kings due to the mysterious powers they wield. Their power allows them to destroy armies alone, guide their people to greatness, split mountains with their bare hands, and even kill the strongest monsters.
Yet even after all these years, the origin of their powers remains unknown.
A once ugly and sickly kid is transported into this world. He’s granted powers beyond his own control. He must quickly grow strong, lest he risks destroying himself as well as the world around him.
His ultimate goal? To "live as long as he can". This desire, although simple, will herald his rise as the "Silver King" the world once feared.
