Irkin’s friend, Kostya, saw such a “game” for the first time. In addition, the timer was alarming, inexorably ticking off the time remaining before the disaster. And then it turned out that the explosion of the Earth was already clearly planned in another place! This place is nothing other than the domain of the Black Emperor! And the guys, wanting to prevent a tragedy, make a grand journey to... 2000 BC! But the evil spirits of the Black Empire are already waiting for uninvited guests...
