Li Yizheng traveled to the Daqian Dynasty and became the current ninth prince and the prince's younger brother. Just when Li Yizheng thought he could live in peace, the prince rebelled and was killed, his biological mother was thrown into the cold palace, and the officials around him were liquidated one after another. It was his turn before he saw it. Rather than become a useless prince trapped in the courtyard, Li Yizheng immediately proposed to go to the border to guard the border for Da Qian.
While others are still fighting for the crown prince's position, father's favor, money and jewels, I, the prince, have already trained millions of soldiers in the north, and all the soldiers in Daqian are following my lead. Many years later, when the walls of Dagan Kyoto were surrounded by enemies, all the civil and military officials of the dynasty knelt down and begged me to ascend the throne and return to the dynasty.
