Li Yu, a modern young man, traveled through time overnight and woke up as a hungry and cold refugee in Chang'an, the prosperous Tang Dynasty. In this prosperous Kaiyuan era when literary talent and power coexisted, he was penniless but possessed knowledge that spanned thousands of years.
From the survival abacus in the shops in the West Market to the economic and national policy discussions in the court; from a stunning song "Spring Evening in the Garden" to the breathtaking poem "Out of the Fortress", he relied on his wisdom and foresight to use "systematic science" as a springboard, starting from the ninth grade of relics, and worked step by step.
He improved water transportation, helped the victims, and discerned the long-term shortcomings of official administration at the lowest level; he assisted the East Palace and made a strategy to "seize Yang from Yin". In the huge waves of the Anshi Rebellion, he became the pillar of support for the crisis and the reconstruction of the Tang Dynasty.
However, the pinnacle of power is also the eye of the storm. Faced with the frame-up of Prime Minister Li Linfu, the differences in family status, and the cross-class friendship between him and the noble girl Su Wanqing, how should he break the situation?
This is a thorny road that can change your destiny. Let's see how Li Yu uses his millennium wisdom to navigate the turbulent court and turn the tide. Finally, he finds his own destiny between his personal emotions and his family and the world, and personally participates in and rewrites a glorious epic of the rise and fall of the Tang Dynasty.
