In the Liang Dynasty, Cui Yu Lan’s mother died in childbirth. Accused of being an ill-omened star who would bring misfortune to her parents, Cui Yu Lan was sent to the northern frontier overnight and placed under General Yang Zhen Yuan’s care. Seventeen years passed in a flash. Forgotten by the Minister of Justice’s household, the eldest daughter, Cui Yu Lan, had grown into a young woman skilled in medicine and military strategy, thanks to her master and his wife. The wedding of the Minister’s second daughter, Cui Yu Xin, to the Grand Prince Liang Tian Ji was fast approaching when the prince fell from his horse during the autumn hunt and broke his leg. Cui Yu Xin didn’t want to marry a man who was now crippled, so, under the scheme devised by her birth mother, Liu Ru Hua, she summoned Cui Yu Lan back to the capital to marry the prince in her place. By chance, Cui Yu Lan decided that the man she was to marry wasn’t so bad after all. She also wanted to put her master and his wife at ease, and planned to return to the northern frontier once Liang Tian Ji died, where she could live in peace, far from the detestable people and affairs of the capital. So she agreed to the marriage. After the wedding, Cui Yu Lan gained an extraordinary System left behind by her mother. With her help, Liang Tian Ji gradually recovered, growing from a disgraced prince into the ruler of the empire, while Cui Yu Lan found the right man for her.
