Your Majesty! The Princess Royal Has Gone to War Again

The protagonist transmigrates to ancient times, becomes a Grand Princess, and awakens a doglike System. She needs enemy points to exchange for good items, so the Grand Princess spends every day itching to head to the battlefield and earn some pocket money. This is a parallel world. The protagonist is in Qi, which borders Great Yue and Great Liang. To the north are the Xiongnu, and to the south are the Southern Barbarians. Qi has four provinces: Huang, Ming, He, and Zhong. Great Yue and Great Liang each have more than ten provinces and over a hundred cities. After Zhao Zirou defeats Great Yue and Great Liang and unifies the Central Plains, she deals with the Xiongnu and the barbarians, then marches overseas and unifies the world.
