Lin Yue, a graduate student researching ancient military culture, unexpectedly transmigrates while visiting a museum. She awakens in the body of a woman from ancient times with a tragic background, and has also lost her memory.
Newly arrived in a world torn by frequent warfare, Lin Yue disguises herself as a man and joins the army to survive. There she meets Li Mingzhe, her childhood sweetheart; Su Chen, an elegant young nobleman; and Zhao Qi, a mature and steady general. All three fall for Lin Yue, who gradually grows stronger with them by her side.
But Lin Yue's outstanding military achievements provoke jealousy, and she is framed for colluding with the enemy. The three men race to clear her name. With the nation in peril, Li Mingzhe heads to the front and is captured, his fate unknown; Su Chen is forced into a political marriage for the sake of his family; and Zhao Qi, gravely wounded, leaves for the frontier.
In this chaotic age, Lin Yue endures countless hardships and becomes embroiled in court conspiracies, power struggles, and the machinations of a mysterious organization. With her wisdom and courage, she repeatedly escapes danger, clears her name, and leads an army against the enemy to protect the peace of her country. As she sets out on yet another military expedition, where will fate lead her and the men in her life?
