Guts and Black Powder

After the Russo-Turkish War, an unusual plague appeared on the battlefields on the west coast of the Black Sea and the Balkans: blight. The blight caused a large number of population deaths and was quickly introduced to the European continent by the Russian army and the French army that later fought against it. Unfortunately, due to thousands of years of human beings fighting each other and natural and man-made disasters, hell officially welcomed the last undead to hell in the Russo-Turkish War - a poor big-headed soldier. From then on, hell was declared full. From then on, the dead infected with the blight could not go to hell, and their souls were trapped in their corpses and wandered around the world. Regardless of whether they are rotten or not, they feed on humans and become crazy walking corpses, called the living dead. Now they are sweeping across the continent. The Tsarist Russian government essentially collapsed, Prussia was destroyed, Austria lost contact, and Napoleon's whereabouts were unknown. In 1815, London, the remaining center of resistance in Europe, fell. There is nothing we can do.
