It tells the story of the desperate situation at the end of the Ming Dynasty. Emperor Chongzhen Zhu Youjian unexpectedly awakened on the eve of his suicide in Meishan. He combined his knowledge of the next three hundred years with the "Ming Dynasty National Destiny System" to reverse the fate of his country's subjugation with unnatural power. He purged the court of traitors with iron and blood, quelled the chaos of rogue bandits, defended Shanhaiguan to defeat the Manchu Qing Dynasty, and then pacified the Nanming separatist regime. From survival in a desperate situation to military and political reform, from the rise of firearms to the dominance of sea power, all the way to sweeping away internal and external troubles, turning the declining Ming Dynasty into an empire on which the sun never sets, and building a new world order with China as the core, the battle of power and wits and the rise of the empire are full of excitement throughout the process.
