Absolute alternative

Only the Empire, the Single Planetary Government, will save humanity from endless strife in the era of high technologies leading to the death of civilization.
Cain knows about it - a strange creature in the case of a robot, reviving the latter, miraculously the preserved resident of the Earth. Cain saw many worlds where the inhabitants missed the opportunity to create a planetary empire before joining the technological era - and therefore died in the fires of thermonuclear wars.
Cain knows how to open the doors in the past. And with his help, the last earthman nickname receives a second chance for his planet. He will be able to try again to do something that His ancestors could - combine the planet and preserve civilization.
Powerful hand of the emperor ... All Earth
