In the early years of Hongwu, the Ming Dynasty was rising, and everything was in ruins waiting to be revived. However, with the enthusiasm of the founding of the country, the undercurrent of the old Yuan Dynasty has not subsided, and the power struggle of the new dynasty has begun. In Tianfu, Kyoto, between the bustling streets and deep mansions, crimes breed like ghosts, tearing apart the splendid curtain of the prosperous age.
This is a historical detective legend with hard-core reasoning as its backbone, Ming Dynasty landscape paintings as its flesh, and youth's passion and growth as its soul.
Four young men, Xu Chu, Ma Wei, Lu Ming, and Zhu Linlin, used "iron, ink, wisdom, and medicine" as tools to pierce the fog of the Hongwu years, and wrote their own footnotes on punishment in the heat and chaos of the dynasty's founding.
