He Stole My Kingdom, I Stole His Throne!

Ning Wuyu was the eldest princess of Da Shu, and she married Xie Wei, a hostage prince held from Nanliang, because she wanted to and because she thought she knew him. She knelt seven days to get the marriage allowed. She also passed him the city defense plans of her own kingdom. Before the wedding she found out what he had been arranging with another woman all along. He used the plans, brought the kingdom down, killed her father, and had her put in a dark cell where he could come and humiliate her at his convenience. She let him believe she was broken and made a show of handing her rank and privileges over to her rival. Then she got out. A jade phoenix pendant was the token that called up three thousand secret guards who had been waiting on it, and she took them and set the city burning. She made an alliance with Gu Changyan, a prince of the South who had understood what she was long before any of this, and turned the army she now had back toward the man she had married.
