Lin Yan, a modern international strategic scholar, accidentally traveled back to the ninth year of Hongwu in the Ming Dynasty while repairing a mysterious pocket watch from the Yongle period in the Forbidden City, and became Xu Miaoyun, the eldest daughter of the founding general Xu Da.
According to historical records, Xu Miaoyun was the "virtuous and gentle" Princess Yan and the virtuous wife of Emperor Yongle. But Lin Yan knew that the future queen was more than that. The hemispheric chart in the pocket watch and the motto "where the sun and the moon shine together, where the mountains and rivers share the same moment" all seem to imply that Xu Miaoyun himself is a mystery buried by history.
Combining modern memory with ancient identity, she decided not to repeat the silent life recorded in history books. On a snowy night in Zhongshan, she made a "three-year agreement" with Zhu Di, the future king of Yan: she would help him revolutionize the land of Yan, enrich the country and strengthen its army; he allowed her to participate in political affairs and work together with the world.
From then on, the boudoir embroidered pictures concealed the border defense strategy, and a remark made during the Lantern Festival alarmed the court. From the Peking Trading Company to the Firearms Camp, from the "Yongle Ceremony" to Zheng He's voyages to the West, as a woman, she held half a gold seal and walked side by side with Zhu Di through the Jingnan War, the power struggle in the court, and the Northern Expedition, step by step pushing this ancient dynasty to unprecedented openness and prosperity.
But the secret of the pocket watch always follows: Why is she here? Where does the phrase "the sun and the moon shine together" point to? When ideals touch imperial power, when love meets mountains and rivers, when the prophet of a time traveler meets the torrent of history - can she truly change an era instead of just becoming another vague footnote in the history books?
This is a conversation that spans six hundred years, and the legend of a woman who lit up a spark in the dark river of history.
