Li Che, a graduate student in the Department of Modern History, accidentally traveled to the Qin State at the end of the Warring States Period and awakened to the "modern system." The system gives him top intelligence, strategy and martial arts potential, and allows him to access all knowledge in the modern world at any time. Starting from obtaining the first pack of high-quality seeds, Li Che worked quietly at the bottom of the Qin State - improving farm tools, increasing output, and improving technology, gradually accumulating reputation and strength. Relying on the knowledge that transcends the times and the military books and military training methods that are systematically rewarded, he gradually rises from a commoner to the power of the Qin State, and eventually becomes the most trusted minister and best friend of Qin Shihuang Yingzheng. He assisted Ying Zheng to not only unify the six kingdoms, but also pushed Qin's territory and civilization to the entire Asia, establishing an unprecedented huge empire. At the peak of their achievements, the two chose to retreat behind the scenes together, leaving the stage to the new generation, and their wisdom and legends influenced the direction of history for thousands of years.
