Adam Ondra:

The idea of linking those 28 moves, consistently intense, felt almost impossible, but there was one trick that made it possible. A kneebar, that looked impossible to release the hands at first, but everything is trainable. [1]

9b/b+ as a route.

Ledoborec (Icebreaker in English) is a 28 moves long boulder problem and could as well be graded 9b/b+ route. It links 8B boulder problem called Blatant, which is very tricky on some of the poorest and the most slippery holds I have ever seen, directly into 8C called Iceberg. [2]
