An abandoned daughter from the Cheng Hou Mansion, with scars on her face, was exiled to Northern Xinjiang. Mu Wantang bound the system and counterattacked from selling ointment in the wasteland to a mysterious businessman in the capital. In order to completely clear her name, she entered into a contract marriage with the cold-faced Ninth Prince, ostensibly husband and wife, but secretly an ally. When the business war escalated into a deadlock in the court, it was revealed that her husband was an orphan from the previous dynasty, and every move made by the seriously ill emperor hid the murderous intention of burying both of them together. This is a marriage that started with a transaction, but I don't know in the end, will it be machinations that swallow up the sincerity, or will the sincerity break the deadlock?
