Scientists study the human brain and find a way to travel in time. Using gene chromosomal memory, they penetrate the past. Scientists fall into different eras, record a lot of interesting things, and our hero gets into various adventures from the lives of their ancestors. These are the times of Neanderthals, dinosaurs and others.

Eventually, the person they use is harmed and eventually turns into a monster.

A story based on my book: "Meeting". The book is sold freely on the Internet. It is possible to make a lot of series (until you get bored).
