A modern soul travels back in time to become the unpopular deposed prince Louis of the Xia Dynasty. At the beginning, he only has a dilapidated fiefdom and a gentle wife Su Qingyao. Thanks to the blessing of the "auxiliary system", he started by improving farm tools and developing agriculture, and gradually accumulated strength; he recruited troops and horses to put down border rebellions, implemented reforms and rectified government affairs, conquered Baiyue in the south, connected with the Western Regions in the west, defended the Huns in the north, and defended against Japanese pirates in the east. Step by step, he counterattacked from a border prince to a ruler. In the end, he inherited the imperial edict and ascended the throne as emperor, creating the "Yongxi Prosperous Era" and making Daxia a world power that could be visited by all nations. The story not only contains the passionate struggle for hegemony, but also the warmth of mutual friendship with Su Qingyao, and the feelings of family and country that strive to govern and benefit the people, writing a legendary life from an abandoned son to an emperor through the ages.
