After Twin Births, the Prince and Princess Join Hands to Defeat the Enemy

The male and female protagonists are reborn and return. The female protagonist is strong and the male protagonist is weak (weak only in front of the female protagonist). The female protagonist helps the male protagonist to smash the prince's conspiracy, ascend to the throne, defeat the Northern Barbarians and Southern Xiongnu, conquer the other three countries of the Central Plains, and thus sweep away Liuhe.
