In the 22nd century, Lin Yuan, a college student in the Department of Archeology, accidentally triggered a mysterious jade during an excavation of a Qin tomb. He traveled to Xianyang in the 26th year of Qin Shihuang (221 BC) and became the son of a low-level official who had just lost his father. With the system of "Guardian of Civilization", he survived in the cracks between the strict Qin laws and the treacherous court. From the market accountant to the scribe of the Prime Minister's Mansion, from supervising the transportation of the Great Wall to supervising the construction of the Lishan Mausoleum, he personally experienced major historical events such as the Book Burning Order, the Sand Dune Incident, and the Daze Township Uprising. He improved farm tools to benefit the people, risked his life to collect books to continue civilization, established "Wangshu Village" to inherit the fire in troubled times, and finally lived in seclusion in Bashu in the early Han Dynasty, passing on the mission of civilization spanning two thousand years to the future.
