After three years on the battlefield, the wife returns victorious, but unexpectedly pregnant! The former Grand Marshal of the empire's army had retired due to his parents' last wishes and married a woman known for her bravery and ambition. She aspired to achieve greatness on the battlefield, and before she left, he gifted her a legendary spear forged from thousand-year-old cold iron. Three years later, she returns clad in silver armor, pregnant, and holding another man's hand. She presents a letter of divorce, declaring, "My husband must be a heroic figure who stands tall, not a weak scholar with no strength." Unbeknownst to her, the seemingly powerless man she had married was actually the empire’s guardian deity. When he dons his marshal armor once again and takes up his legendary weapon, she finally realizes the true identity of the man she once scorned.
