On the first day after she came down from the mountain after completing her studies, her father, the only legitimate daughter of the general's palace, was stuffed into a small sedan chair and carried into the back door of the benefactor's house in the name of repaying his kindness. She was made a wedding bride, and she was also a concubine! The reason is that the notorious eldest brother, who killed several fiancées, doesn't want to marry? Is this a joke? Are you kidding me? Originally, she married her because she could have a disguised identity so that she could complete the mission of the Demon Sect, but look what she encountered? The intrigues in the backyard, the frame-ups everywhere, and the hatred of the country and the family are mixed in... Dad, are you repaying a favor or taking revenge? What should she do when she encounters so many interesting things that make her want to take action?
