After Gael's attack which was executed by him at full severity, staying alive was almost impossible. Alucard didn't resist in any way, and it didn't matter whether he wanted to or not, so every Gael's swing reached its target.
Even Liang, in his Form, could hardly stay alive after something like that. A sharp blade and free streams of ash following their master's will would simply turn him into nothing. That's exactly what happened to Alucard, but Gael didn't worry since he knew that for Alucard it couldn't be a problem.
"How do you like my attack? I haven't gotten weaker?" Gael asked, staring intently at Alucard.
A few seconds was enough for from a few clots of blood, Alucard returned to normal again, becoming who he had always been.
