Countdown to Catastrophe: Border City Safe Zone

Lu Chen transmigrates into the body of the newly appointed county magistrate of Qingshan County in the northern border of the Daqian Dynasty. He wakes up to find himself accused of a capital crime for embezzling grain. Outside the city, refugees besiege the government office; inside, the granary is empty. In seven days, a cold wave will arrive, and Qingshan will be erased from the disaster records. He has no divine powers, nor an all-powerful system, only a disaster calendar that shows the countdown to calamities. He inspects grain, sets up accounts, distributes porridge, builds shelters, manages firewood, takes in refugees, and trains the garrison. Starting with a bowl of thin porridge, a wooden sign, and a city gate, Lu Chen strives to turn this dying border city into the first safe zone in a chaotic world. — Description from novelcodex.org
