Lin Xuan, a former son of a famous family, had to marry into the Su family due to family changes, and became a useless son-in-law that was ridiculed by everyone. Faced with rejection and humiliation from all parties, he kept a low profile and concealed his identity as a descendant of the God of War. The repeated family crises and power disputes made him constantly awaken his instincts, and he grew into a top powerhouse through training. Su Waner originally distrusted Lin Xuan, but discovered his sincerity and protection in difficult moments, and the two gradually formed a deep friendship as husband and wife. Lin Xuan competes among the Su family, the Ye family, and the larger alliance of aristocratic families, not only seeking revenge but also achieving his own redemption. In the end, he rose up domineeringly as a son-in-law and ruled the world.
