Ten paratroopers who have fallen into the past confidently operate in the territory of the part of Rus' they captured in the 13th century, where they are building the state of Russia, gradually expanding their borders and displacing individual princes from their fiefs, sometimes resorting to the help of the Mongols of Batu Khan. They severely punish Europe for attacks on Rus', discouraging it from such desires for the future, and force many countries to pay them tribute. At the same time, they are increasingly raising the standard of living of the people in Russia, introducing literacy training everywhere and developing industrial production, relying on their knowledge.
