This book uses the Jingkang period in the late Northern Song Dynasty as the historical prototype, finely tunes key figures and events, and focuses on the core proposition of "the fragmentation of family and country and personal perseverance". Through the modern soul travel of the protagonist Zhao Chengyu, the core characteristics of light time travel - no system, no space, no heaven-defying golden fingers, only carry modern memory and basic cognition, modern common sense and dimensionality reduction to solve small problems are light and refreshing, fitting the platform's popular light time travel tonality, while retaining the weight of historical texts. The perspective of a grassroots military commander in the late Northern Song Dynasty connects the magnificent scenes of party disputes in the court, border wars, people's displacement and resistance to gold and national salvation. It not only restores the cruelty and helplessness of troubled times, but also praises the glory of human nature and national integrity in desperate situations, allowing readers to experience the close intertwining of personal destiny and the rise and fall of the country in the heavy sense of history.
