About the book: 2017 / It so happened in these worlds that the struggle for the lives of individual representatives, the best representatives - masters, becomes a struggle for the existence of all humanity. Nothing and no one will protect a master better than himself, but it turns out that in order to survive in battle, being a master of a martial art is not enough, it is not enough just to master it perfectly, just to be “the best.” The masters did not master the art of self-defense from several fighters attacking at the same time, and this almost led to their death. And only luck, an important factor, helped them survive. In one of the worlds there lived a man who brought together the best masters to teach them the art of kata, which ultimately saved humanity.
