Rule the Middle Ages with Kpis

There was no gunpowder, no steam engine, and no black technology beyond the times. There is only one hapless modern project manager, whose soul descends into the most barbaric Dark Middle Ages. Faced with the axes of the Vikings, the greed of the feudal lords, and the sharp teeth of plague and famine... The Gantt chart is his marching strategy, risk control is his talisman, and KPI is the only law in his territory. He wants to live on, build a solid foundation, and eventually turn into the immortal spirit of his ancestors. In the long history, he will guide the bloodline and build an unprecedented country of order on the ruins. This is a history of civilization development. The only golden finger is "rationality."
