Ryu was, indeed, in a bit of a predicament. Infinity Mist was an extremely unique existence to begin with, in any other situation, he wouldn't even be capable of creating a void bubble tough enough to withstand a material on this level. Infinity Mist was, luckily, a unique item that was able to solidify space as opposed to destroying it, but it was exactly that… unique.
Another powerful item on this level would only destroy. In fact, items of this caliber warping space and laws around themselves wasn't uncommon in the slightest, it was expected. Just take the lower extremities of this ocean as an example. Further down, there was a great heat that Ryu couldn't even approach. He shouldn't have even been able to feel the heat through the void bubble he was in, but the fact he could meant that the items below were already bending and twisting space.
