Modern engineer Zhang Gong accidentally traveled to Daqin. At this time, Daqin lurked hidden dangers for development. With modern knowledge, he gained the trust of Qin Shihuang Yingzheng.
Zhang Gong first demonstrated his capabilities by improving agricultural tools and machinery, launching industrial experiments, innovating iron smelting technology, manufacturing practical machinery, promoting agricultural reform, and increasing food production. Militarily, he innovated equipment and tactics, established an intelligence system, and formulated a strategy for the unification of Asia for the Qin Dynasty, winning the first battle. However, during the expansion, they encountered resistance from the Canglang Kingdom and other alliances. Zhang Gong formed cavalry, split the alliance, and won the decisive battle on the border.
With its territorial expansion, Da Qin faced cultural and political problems. Zhang Gong promotes cultural integration and respects the characteristics of various regions; carries out political system reform, clarifies responsibilities, strengthens assessment, and selects talents to break through the resistance of the old aristocracy.
With the assistance of Zhang Gong, Daqin's economy prospered, its business expanded, and its science and technology advanced. The dawn of a unified Asia began to emerge, and it entered a glorious new era.
