Qin Mo, a graduate student in modern military history, traveled through time and became a skinny boy outside Huaiyin City in the late Qin Dynasty, whose parents had both died and was bullied. At the same time, Su Wan, a female forensic doctor who fell from a building and died in modern times, transmigrated into the daughter of a Chu clan who was deposed and imprisoned in the cold palace due to a family conspiracy. Relying on his thorough understanding of the history of ancient wars, Qin Mo saw through the systematic tampering and blockade of military classics under the "Book Burning Order", and was determined to use "knowledge" as a blade to break through the fog of ideological imprisonment. His rise aroused the hostility of the Xianyang legal official Zhao Gao and the "poison scholar" Yao Jia, who pursued the concept of "stupiding the people to govern", as well as the calculations of the mysterious counselor "Guigu Shadow", who attempted to lead Qin Mo's talent down a path that would bring disaster to the world.
While escaping and struggling, Qin Mo encounters Su Wan, a deposed concubine who disguises herself as a medical practitioner and tries to find out the truth about her family's injustice. One controls the future, and the other understands the laws of the human heart. The two go from testing each other to working together. Qin Mo used modern military concepts such as "special operations" and "staff system" to integrate refugees and repeatedly defeat the Qin army; Su Wan used modern forensic logic and psychology to clear up internal hidden dangers for him in the dark, and tried to build a new organization and legal prototype. Their actions not only confront Yao Jia and the "Shadow of Ghost Valley" from the outside, but also face the internal battle between "rapid military conquest" and "slow civilized enlightenment". In the end, when the wheel of history rolls towards the decisive battle, Qin Mo and Su Wan must use all the wisdom beyond the times to win not only the war, but also the future in the final chess game laid out by "Shadow in the Ghost Valley", igniting a different spark of civilization for this ancient land.
