Ryu felt the turbulence and was almost thrown off entirely. The pressure of being in such a battle as a mere True Sky God wasn't lost on him. The only reason he had even managed to last so long in the midst of such destruction was because these beasts were all focused on using their greatest strength. As such, they were actively trying not to have their attacks pass through the void.
Although they still tore through space, at the point of actual attack, all of their strength was concentrated and condensed, making Lu'card's powerful body and even his spatial guarding skill look like child's play. However, there was very little Ryu could do about a physical attack like this one. Lu'card took up most of the impact, but he still ended up coughing up several mouthfuls of blood, his body rattling and his bones shattering.
