Synopsis：The former Grand Marshal of the empire laid down his armor and retired to fulfill his parents’ dying wish, marrying a woman famed for her courage and ambition. Dreaming of glory on the battlefield, she left for war, and before she departed, he gifted her a legendary spear forged from thousand-year cold iron. Three years later, she returned in silver armor, visibly pregnant and holding another man’s hand. In front of everyone, she presented a divorce letter: “My husband must be a towering hero, not a weak, bookish coward.” She never imagined that the “powerless” man she scorned was actually the empire’s hidden guardian god of war. When he dons his marshal armor again and wields his mythic weapon, the empire trembles—and she finally realizes that the man she cast aside is the mightiest existence under heaven.
