The soul of Yegor Rokotov has entered the body of a young guy from an alternative world. A world not only different in history from the history of the Earth, where Yegor lived all his life, but also in the laws of the universe and society. Due to the fact that there are several times more women on Earth-2 than men, almost all states adopted a special law, which was popularly called the harem law. And now the young invader will have to, by hook or by crook, refuse the imposed harem and choose girls whom he can love himself and receive love in return. His new family will include beauties who have special, supernatural powers that violate all conceivable laws of physics on Earth-1. But that's not all! The young man will have to face a race of intelligent machines that came to Earth-2 from a parallel world and are waging an irreconcilable war with its inhabitants.
