Gu Jinli replied, "Granny Lei, don't worry. We have a way to preserve cooked dry rations, and it's still a bit cold here in the Northwest, so the dry rations won't spoil within two months."
She went on to explain, "With the Prefecture under siege, if the Rong people poison our water sources, we'll not only have nothing to drink, we won't even have water to cook with. And once the city is besieged, the woodcutters can't come in to sell firewood, so firewood is also a problem. We have a lot of people, and every meal consumes quite a bit of fuel. We need to take advantage of the fact that there's still firewood and turn our grain into dry rations. Also, in wartime, if you can just grab a piece of dry food and eat, it's much more convenient."
