Princess Wife of the Prince Regent

The female protagonist Murong Qing is Princess Da Xuanzhen, and the male protagonist Murong Zhan is the adopted son of the late emperor (the male and female protagonists have no blood relationship, and are nominally uncles and nephews). The story is doted on, and there is no abuse throughout. The modern and ancient heroines are the same person, but she doesn't know it. The National Preceptor will make it clear to her in the end. After the heroine returned to the Daxuan Dynasty, she used the knowledge she had learned in modern times to help the people develop agriculture and established a business kingdom. She also helped the emperor's uncle Murong Zhan completely defeat the barbarians on the frontier, so that the people of the world could live and work in peace and contentment. During this process, Murong Zhan was constantly attracted by her talent and ability. After learning his true identity, she opened her heart and worked with him to protect the stability of the people of Daxuan and the border.
