During the Hongwu period of the Ming Dynasty (1368-1398), when Zhu Yuanzhang established the Ming Dynasty, the political power was initially established but undercurrents were surging. The imperial court purged heroes (Hu Weiyong case, Lan Yu case), the remaining forces of the Yuan Dynasty (Northern Yuan Dynasty) were spying on them, Jianghu sects were divided and reorganized, and the Jin Yiwei first appeared. The society appears stable on the surface, but in fact power struggles and people's livelihoods are in decline, with individuals struggling to survive in the cracks.
