In a certain kingdom, a certain state, lived Tsar Eremei with his three sons. He occupied all his days with an affair of state of the highest importance, namely, that he dictated his memoirs on the exploits he had not accomplished. And now, once, in the middle of the day, we discovered at the edge of the kingdom a fantastic being of the dragon type, and to put it more simply, a Tchoudo-Ioudo. And the Tsar sent his sons to defeat this monster and increase the glory of the Tsar's lineage. But, while the eldest sons slept, and Ivan fought with the monster, it turned out that the Tsarina Varvara of the Neighbor Kingdom had disappeared. And so Ivan went looking for her. And he took with him the Chudo Yudo. Just like that, by chance. And if we needed it along the way. But the only thing Ivan didn't know is that this dragon was not at all what we thought.
