16+ Humanoids from the Galactical Empire arrived in the Solar System, to the planet Earth, to carry out an experiment transferring a human’s consciousness into another parallel world that is a hundred years behind our time. The goal of the experiment is to find out whether one person can direct the course of history along a different branch. The donor is our contemporary—a retired intelligence colonel, Dmitry Ryu min. His consciousness is transferred into the body of a young officer of the Tsarist army, the grandson of a Grand Duke and a bastard. Dmitry simply serves the new Fatherland. At the same time, knowing from his own history all the problems, he takes measures—sometimes radical ones. But that doesn’t bother him. After all, he has to live in this world a second life. Will the aliens’ experiment be successful or not?
