History reaches the beginning of the twenty-first century and... freezes. Why? Forget everything you knew about time. Plunge into the world of four dimensions, where people travel to the next century just like to the next city. Welcome. If your nose bleeds, don't be afraid, this happens to those who travel through time for the first time. Forget everything you knew about history. Plunge into a world where people literally experience the ups and downs of civilization and, after rising to progress, fall into the abyss of war. If they shoot, be afraid, you might get shot too. Is it possible to survive the ups without the downs? Is there any path from the past to the future that is not stained with blood? Maybe you will find this path.
