During a total solar eclipse observation, astrophysics professor Yu Chen is caught in a magnetic storm and transmigrates to the outskirts of Xianyang in 247 BC, bringing with him a modern knowledge base. He forms a special bond with Ying Zheng, who has yet to take power, and gradually earns his trust by resolving crises such as the plague along the Wei River and improving farming tools. From papermaking and printing to metallurgy and smithing, he reshapes the foundations of Qin through a gradual technological progression, establishing a research system centered on the “Mohist Academy.” Caught between Lü Buwei and Zhao Ji's political maneuvering, he uses modern management principles to restructure the Qin court's power system and train a new generation of technical officials. By creating a patent system and a system of compulsory education, he lays the foundations for sustainable development while preserving the Qin system, avoiding the cycles of history and forcibly extending Great Qin's life by 200 years.
