In the final years of the Great Jing dynasty, imperial power crumbles, warlords carve up the realm, and flames of war spread everywhere.
Shen Jinghong, the legitimate daughter of a military family, is suddenly branded a traitor who colluded with the enemy. She watches her entire family slaughtered on Vermilion Bird Street. Rescued at the cost of a loyal servant's life, she flees to the frontier with a secret edict from the late emperor, concealing her identity and lying low to survive against all odds.
To avenge her family and clear their name, she sheds her woman's attire, disguises herself as a man, and joins the Jingyuan Army. With her martial prowess and extraordinary strategic mind, she earns one remarkable victory after another, rising from an unknown soldier to a commander feared across the borderlands. She uncovers plots within the army and wins over the troops under her command. Even after her identity is exposed, her lofty ambitions win everyone over.
When the army returns to the capital, she presents the secret edict to the emperor and vows to expose the mastermind and clear the Shen family's name. In court, she turns her enemies' own schemes against them and dismantles the powerful ministers' factions. When the warlords rebel, she leads troops to quell the uprising. Her glorious victories shatter the prejudice that women cannot command armies, and she rises to become a General Who Guards the Nation.
From an orphaned girl to a god of war, Shen Jinghong shoulders the fate of her country in a time of chaos. She purges traitors, repels foreign invaders, and supports a wise ruler, ultimately bringing peace to the realm. At the height of her success, she turns away from power and retreats to the mountains, leaving behind a legendary heroine whose name shines in the history books.
