In the seventh year of Huangchu, Emperor Wen of Wei Cao Pi suddenly died. The 22-year-old Cao Rui came to the throne at the critical moment and took over the precarious Wei Dynasty, which was dominated by nobles inside and surrounded by Wu and Shu. Sima Yi, a veteran of the two dynasties, has been dormant for half his life. He has the roots of a noble family and harbors ambitions to usurp the world. He is recognized by both the government and the public as a pillar of the country, and he is also a tomb tiger with hidden evil intentions. Everyone in the world was intoxicated by Sima's obedience and diligence, but Cao Rui penetrated his wolfish ambition with his ruthless emperor's mental skills tempered in the palace. This book adopts a narrative mode intertwined with the first-person perspective of the two protagonists Cao Rui and Sima Yi + the perspectives of group portraits in the Wei Dynasty. It covers the multi-party game between clan members and generals, civil servants, harem power, and military factions. There is no golden finger from the sky, no forced wisdom, and no reconciliation between the king and his ministers. The whole process is a real and cold top-level conspiracy that pulls the young emperor to spend his whole life to build a network of heaven and earth, dismantle Sima's power layer by layer, divide the noble clan members, suppress the conspiracy of father and son, and rewrite the short-lived fate against the will of heaven. In the end, he uses a lifetime of checks and balances to lock the ambition of the tiger, defend the Cao family's thousands of miles, and achieve the prosperous age of the Wei Dynasty.
