"Qin Shi Zhi Ding" tells the story of Lin Mo, a talented double-major student from Tsinghua University, who accidentally traveled to the Qin Dynasty in 215 BC due to a laboratory accident and became a prisoner in Lishan. Facing the harsh ancient living environment, he relied on modern science and historical knowledge to gradually enter the power center of the Qin Dynasty, starting from cracking the Xiongnu spy conspiracy and improving military equipment and agricultural tools. In Xianyang Palace, he discussed Taoist reform with Fusu and dealt with Li Si's disciples; outside the fortress of northern Xinjiang, he helped Mengtian reform defense and fought wits and courage with the Huns' cavalry. After the Sand Dune Incident, he faked his death and lived in seclusion in Bashu. He established the "Moxue Village" to spread knowledge. He became an invisible pusher in the war between Chu and Han, and quietly implanted the scientific fire and people-oriented concepts into the current of the times. He refused to be granted the title of marquis by Liu Bang, but laid the foundation of the system in the early Han Dynasty with "Essentials of Governing the Country" and "Quan Shu". This is not a myth about one person changing the world, but a lonely long march of a modern soul in the huge waves of history, using wisdom as a boat and knowledge as an oar, to create new possibilities in impossible places. When the starlight of civilization travels through the two thousand years of night, it illuminates not only the darkness at the turn of the Qin and Han Dynasties, but also the eternal glimmer of human reason.
