[Imaginary history + city defense and survival + management and construction + no system]
In the troubled times of the late Tang Dynasty, the county magistrate took away the relief money and abandoned the city and fled, but Han Du's sister and more than a dozen lives were still locked up in the official warehouse.
Han Du was just a small official in charge of the grain accounts. There is no system, no way to make gunpowder, and only the official robe and official seal left by the escaped official. In order to open a warehouse and save people, he put on his robe and stamped his seal, pretended to be the new county magistrate, and smashed open the warehouse door with an order.
But as soon as the warehouse door opened, he couldn't take off his official robe: there were two thousand stones in the account, and less than half of them could take the pot; the rebel army outside the city was approaching, and the wealthy people in the city took the grain deed to seal the warehouse; the real county magistrate who had escaped came back with his troops, and wanted to label all the people receiving grain as rebels.
Checking grain, defending the city, resettling refugees, dividing military fields, linking counties to build roads... Every time Han Du rescued a group of people, the crime of impersonating an official became more serious.
Until an isolated city became a mutual guarantee for five counties, the court and the feudal town came to ask at the same time: Should this fake county magistrate be killed or sealed?
