The story is based on the life of Zhang Heng, a famous official in the Northern Song Dynasty, and is integrated into the "soul-transportation symbiosis" setting of modern history researcher Lin Xiao. It not only respects the historical facts such as imperial examinations, finance, diplomacy, and flood control in "A Brief Introduction to Zhang Heng's Life", but also adds interactive lines of famous officials from the same period such as Fan Zhongyan, Di Qing, Zhang Zai, Zhou Dunyi, and Wang Shao. Through "ideological inheritance and practical guidance" ", cross-field collaboration" deepens the relationship between characters, and strives to "no fiction in historical facts, no suspension in creation"; the emotional line strictly follows the principle of "monogamy + confidants + restrained love"; the character interaction closely follows the main line of "improving the imperial examination - economics of the world and the people - party struggle to break the situation - regaining Yanyun", setting up suspense and connecting back and forth, with no gaps in foreshadowing.
