A modern girl traveled through time and became Lu Shu, the legitimate daughter of the Lu family in Fan Yang. Before she had time to be happy, she realized that this was the Xuanzong period when the Anshi Rebellion was destined to occur. The rebellion originated from Fan Yang, and she must stop the Anshi Rebellion for her country and her family. Lu Shu knew that the fundamental problem lay in the annexation of land and the separatist rule of vassal towns, but if he only killed An Lushan, it would intensify the conflict. Lu Shu tried to persuade Xuanzong to curb the increasingly serious land annexation through her father who served in the Ministry of War, Xuanzong's son Prince Zhong, and the current prime minister Zhang Jiuling. Unfortunately, Xuanzong was addicted to pleasure in his old age and was still unwilling to reform the bad government. In desperation, Lu Shu had the idea of forcing him to abdicate, but she had no specific strategy. He had no choice but to go to Beiting with his childhood sweetheart Li Mi to persuade Guo Ziyi, the general who put down the Anshi Rebellion, to rescue Tongguan first. On the way, they met Zheng Wei, an ambitious son of an aristocratic family, and headed together to the Turks who would join the rebels in the future. Lu Shu successfully made the Turkic Khan promise to maintain peace with the Tang Dynasty. Then she successfully persuaded Guo Ziyi and went directly to Tongguan to rescue him. At the same time, another incident occurred in the Lu family of Fan Yang, and Lu Shu's father was targeted and framed by Li Linfu. Lu Shu, who rushed home, failed the frame-up plan and was almost in danger. Li Mi was also repeatedly framed for assisting the prince. Lu Shu decided to put aside her estrangement and persuade Zheng Weixiang to help the prince. However, before the prince had enough power to launch a mutiny, the Anshi Rebellion had already occurred.
