I was shocked to learn recently how diverse various parts of Russia is. There's hardly anything common uniting Russia including language. Russia is so huge simply because they did not had mountains to protect from marching invaders and the kings solution was to keep marching until they found mountains to define the boundaries. Along the way they made treaties with all sorts of culture and it became Russia.

This is an incredibly wrong understanding of Russian history.

There are in fact mountains going North-South threw Russia and apparently they didn't stop there.

And of course like any huge country it does not have uniform culture.

Is there any common thing that unites Russia. For example majority of the population in china believe they are the descendants of chinese emperors from Han dynasty.
