Jiang Li, the unpopular third princess of Anguo, is actually the daughter of Qi Mohan, the regent of Rongguo. After the eldest princess and the second princess were personally destroyed in order to avoid peace, she was pushed to the position of marriage, but in fact she was the abandoned son of Emperor An. She was also intercepted and killed by his shadow guards. Fortunately, she was rescued by her uncle Chu Yanzhou. After arriving in Rongguo and recognizing her ancestors, she was taken advantage of by Qi Mohan and forced to marry the puppet emperor of Rongguo in order to give birth to an heir. Jiang Li, who saw through the calculations of all parties, secretly planned to unite the forces of the Chu family and take advantage of Qi Mohan's rebellion to counterattack. Finally, he put down the palace rebellion, supported his adopted son to ascend the throne, and became the regent queen mother herself. She implemented the New Deal, founded a school for girls, and later led the army to destroy Anguo, completely getting rid of the fate of marrying the princess.
