Shall Steel Wield Arcane Power?

Synopsis

The invincible warrior Arthur, who possesses the power to kill gods with bare hands, followed his master's orders to marry the declining Norman family, and married the seriously ill young lady Rosalind. Faced with the contempt of his family and the difficulties of various villains, Arthur, who was regarded as a "magical waste", used absolute physical violence to crush all magic laws. Not only did he cure his beloved wife and help her awaken her top talents, but he also defeated strong enemies such as the Imperial Magic Knights along the way. Finally, the supreme god descended and publicly knelt before Arthur, revealing his identity as the "uncrowned king". Arthur climbed to the top of the empire with his beloved wife.
