This book uses a first-person perspective and uses the life of the witness "Zhao Chen" as a clue to completely connect the nearly sixty years of history from the outbreak of the Changping War in the 45th year of King Zhaoxiang of Qin (262 BC) to the surrender of Prince Qin Ying in the first year of Emperor Gaozu of the Han Dynasty (206 BC) and the collapse of the Qin Dynasty. The protagonist Zhao Chen is a fictional character. He was born in an old Qin family in Yueyang, Guanzhong. He has been a Qin official for generations. Throughout his life, he has served as a county official in Yueyang, the head of the Yushifu, the history of the Tingwei Palace, and an official of the Langzhong Order. He has personally experienced the complete rise and fall of the Qin State from sweeping Liuhe, unifying the world, establishing laws and regulations, to the Sand Dune Change, the chaos in the world, and the destruction of Xianyang City. All major historical events and core figures strictly follow historical records such as "Historical Records", "Zi Zhi Tong Jian", "Sleeping Tiger Land Qin Slips" and other historical records. The details are reasonably fictitious. What is seen, heard, felt and thought from the first perspective is used to restore a real, three-dimensional and flesh-and-blood Qin Dynasty, rather than a facial expression of the "violent Qin" label. The book has a total of about 120,000 words and is divided into seven volumes. It completely covers the entire process of the Qin Dynasty from its rise, prosperity to its fall. It includes the changes in the power of the court, the heroic battles on the battlefield, the long-lasting achievements of system construction, and the hidden worries of people's livelihood in the prosperous age. It also contains the personal understanding and deep reflection of an old Qin man on the rise and fall of the dynasty.
