The adventures of our contemporary Yaroslav Feofilov in the 9th century continue! Having barely fought off the Vikings and Khazars, Yaroslav found himself faced with a new threat - a large steppe invasion of the Polovtsians. But this is not so bad - his new ally Byzantium asks for support in the fight against the growing caliphate, and Feofilov will have to organize a full-scale military expedition. Will Yaroslav cope? After all, he is faced with a task that no ruler has ever faced - to be in two places at the same time. With one powerful blow, overthrow the steppe cavalry and, instead of returning to their homes, pay a friendly visit to the Byzantines. And all this quickly, all this at a pace, until the Vikings who “received a blow” came to their senses and tried to take revenge.
