Fantastic Russia. The Secret City of Geniuses. Part 2

This part tells how the kids got acquainted with the secret town they ended up in, its secrets, and what the people living there were doing. There lived scientists and warriors—true patriots of Russia and geniuses. You could say their inventions were magical and kept under the strictest secrecy. It was a service for the good of the homeland. Despite the dangers, the boys never lost their sense of humor; all of them decided to stay there. For them, a new stage in life began.
