The protagonist Li Yan (later named Zhu Wei) is under the secret edict of Emperor Chongzhen. He uses the search for the fragments of the "Yongle Dadian" scattered around the world as the overt line, and the practice of "rural encirclement of the city + Taoism and Mo thought + modern strategy" as the underline. In the chaotic times of the late Ming Dynasty, he circled between the imperial court, the rebels, the Manchu and Qing Dynasty, and Western forces. He recruited all kinds of confidants, gradually strengthened them, and finally achieved the great cause of "protecting the country's surname".
