Jiang Ning, the legitimate daughter of the Jiang Mansion, was given a marriage to Gu Huaian who was nine thousand years old. Everyone felt sorry for her, but she was secretly happy because Gu Huaian was an eunuch and could avoid the pain of childbirth. On their wedding night, she accidentally discovered that Gu Huaian was not a real eunuch and was shocked. After their marriage, Gu Huaian protected her in every possible way, but Jiang Ning secretly drank Bizi Soup. After being discovered, she was put under house arrest. Later, Gu Huaian relented and would not force her to have a child for the time being. Jiang Ning gradually fell in love with each other, and after learning that Gu Huaian wanted to change the government, she chose to be with him. After the emperor died, the prince set up a trap. Gu Huaian was prepared to counterattack, and finally supported the young emperor to ascend the throne as regent, and Jiang Ning became the regent princess. The two stayed together and agreed to go to Jiangnan together in the future.
