Yu Anning, as the daughter of the Lord of Jade City, her city was destroyed and her family died. Su Yeli, her playmate who grew up together, took Yu Anning to escape from the war-torn Jade City and came to Kyoto. Su Yeli left Yu Anning behind a letter and left Yu Anning. With the purpose of revenge, Yu Anning got acquainted with the man she was engaged to. Liang Wei, in the turbulent times, in order to take revenge, Yu Anning pretended to be a man and joined the army. After being discovered by Liang Wei, instead of exposing him, he helped conceal it. The two gradually became familiar with each other. At this time, Su Yeli appeared again, and with him was the truth about the destruction of Yucheng.
