Modern people travel through time and become Zhu Youjian. After lurking and planning during the Tianqi years, he not only wants to save the dynasty with an iron fist, but also reshapes the national machinery with a vision that transcends the times. He overthrew the old system, created a "dual cabinet" and "professional ministries", trained princes in the process of expansion, and finally abdicated the throne during its heyday, transforming the Ming Dynasty from a traditional empire into a "constitutional monarchy" federal government with early modernization characteristics.
