During the Later Tang Dynasty, the world was torn apart. In the third year of Tiancheng, the Khitans from the north suddenly attacked Jinyang Palace in the northern capital. After a fierce battle, the second prince Li Hengyi and the fraternal general Xia Chi were sent to the north to fight against the Khitans. Afterwards, Li Hengyi returned to the court victoriously, but Xia Chi was left behind on the border. Princess Jinyi and Xia Chi are childhood sweethearts, so they have doubts.
To put it simply, the princess waits for the general, the kind-hearted eldest son and the second child do not compete for the throne, the cruel third child competes for the throne, and then there is a general cousin who looks very similar to the general and loves the princess very much. Then the family kills each other.
