Ling Lan transmigrates as the eldest legitimate daughter of the Duke of Zhenguo’s household. At five, her birth mother secretly sends her to live with a hunter on the frontier, where she becomes a kitchen maid. Later, northern forces abduct her to the grasslands, and she endures untold hardship as a slave. When she comes of age, Ling Lan returns to the capital to uncover the truth about her origins. After learning the secret from her birth mother, she leaves in sorrow, intending to return to her lodgings. But halfway there, she hears that rebel forces have breached the city, the imperial family has been massacred, and the nobles have all been imprisoned. Her birth mother has also died in prison. Ling Lan immediately turns back for the capital. After paying her respects to her mother, she resolves to take revenge and find a safe home for those who have followed her. By a twist of fate, she rescues Song Qi, the only prince of the imperial family to escape. The two form an alliance and join forces to plan carefully, defeating the various warlords and rallying scattered forces. In the end, they pacify the land, reclaim the realm, and restore peace.
