To save the Earth, a time magician with a thousand years of experience inhabits the body of a young man who, in a family of aristocrats, turned out to be mentally retarded. The temptation is great, because you can have a blast, enjoying earthly pleasures and surprising not only your large family, but also those around you. Meanwhile, a global cataclysm is just around the corner! But how can it be prevented if, having possessed a guy with a damaged brain, the chronomagist has lost a significant part of his abilities and now has to develop everything again.
