Su Yan, a double master of modern history and archeology, accidentally triggered a time and space vortex during the archeology of Xiaoling Mausoleum in the Ming Dynasty and traveled to the first year of Hongwu. Relying on his deep understanding of Ming history and awakening to the "Emperor Development System", he shocked the court with his accurate predictions at the beginning, and became Zhu Yuanzhang's most relied upon adviser from a commoner.
Holding the "Complete History of the Ming Dynasty" in hand, Su Yan traveled among the torrents of history. He helped Zhu Yuanzhang eliminate Hu Weiyong's party members, reform the imperial examination system, promote firearms innovation, and even "spoiled" the Jingnan Campaign in exchange for room for reform after Zhu Biao succeeded to the throne. However, as the historical line continues to change, the butterfly effect of the system warning becomes more and more intense: the prince who should have died early survives, the vassal king who should have been destroyed rises, and history is rushing in an unknown direction...
When the prosperous age of Yongle came ahead of schedule, Su Yan discovered that a greater crisis was brewing - the rift in time and space was expanding, and the Ming Xiaoling Tombs in the two time and spaces had strange resonances. Should we continue to change history and create an ideal dynasty, or should we maintain the order of time and space and protect the inheritance of civilization? In this chess game that spans six hundred years, every move is a life-or-death decision.
A bright mirror reflects the past and present, and reflects the rise and fall of time and space. This is the ultimate game about history, power and human nature.
