Why Are You Crying When I Become the Supreme Emperor?

As a modern person, Chen Xuan traveled to the Daxia Dynasty in the parallel world and became the concubine of the Minister of Household Affairs. At this time, the Great Xia Dynasty was in a period of doubts about the country and internal and external difficulties. Chen Xuan also became a victim of the political struggle and was arranged to replace his brother to marry the legendary Princess Ningguo who was seriously ill and marry into the royal family. It's just that after Chen Xuan "married" into the princess's palace, he found an environment where he could show off his talents, and he was appreciated by the emperor's brother-in-law, and eventually became the savior of the entire empire step by step.
