"The Founder of the Empire: The Biography of Li Si" takes the background from the end of the Warring States Period to the collapse of the Qin Empire, and presents a panoramic view of Li Si's legendary life and complicated destiny. This book provides an in-depth analysis of how this petty official of Chu State relied on the awakening of "hamster enlightenment" to march westward to strengthen the Qin Dynasty, assisted the First Emperor in completing the great cause of unification with Legalist wisdom, and created core systems such as the system of counties and counties, the same text for books, and the same track for cars, which have influenced China for two thousand years. By depicting his ideological confrontation with Han Fei, his power game with Zhao Gao, and his difficult choices in the historical incident of burning books and humiliating Confucian scholars, it reveals the pursuit of ideals and the alienation of human nature among intellectuals in the power field. The work not only presents his talent and strategy as the designer of the imperial blueprint, but also reflects on the tragic origins of his being trapped in the Sand Dune Incident in his later years. It uses the eternal lament of the "East Gate Yellow Dog" as a mirror to illuminate the profound paradox of power, system and human nature.
