A modern elite lawyer accidentally traveled to the Wei, Jin, Southern and Northern Dynasties and possessed the body of a young and poor strategist "Lu Yunshen" who had just lost a power struggle and was relegated to the frontier.
At this time, the world was divided, and the North and the South were in conflict. His country, the Northern Yan Kingdom (which could be fictional, or embedded in a real dynasty, such as the early Northern Wei Dynasty) was troubled by internal and external troubles: the young ruler was suspicious of the country, the Queen Mother was behind the curtain, foreign relatives were monopolizing power, the conflicts between Hu and Han were sharp, powerful land annexers were annexing, and the people were in dire straits.
With insight, logical thinking and control over people's minds far beyond the times, Lu Yunshen started from a frontier clerk, and took an accurate "celestial prediction" (actually a natural disaster inferred based on modern geographical and meteorological knowledge) as an opportunity to return to the center of power. He assisted the young but precocious emperor and presented "Ten Strategies for Enriching the Country and Strengthening the Army", using thunderous means to carry out reforms, rectify the administration of officials, promote land equalization, build water conservancy projects, and form a new army.
He played with people's hearts and minds, manipulating relatives, clans, clans, and enemy countries, averting fatal disasters time and time again, overthrowing or subduing political opponents one by one. In the end, he was worshiped as the prime minister, granted the title of Duke, and wielded power in both the government and the public. The emperor's dependence on him turned into absolute trust, and he regarded him as his "sub-father".
However, behind the endless power is a turbulent undercurrent. The old order is being broken, new interest groups are forming, resistance to reform has never disappeared, and the emperor will eventually grow up and take charge of the government... This is a path of machination that can only advance but not retreat.
