The moment Azul hold out his palm, the entire origin energy of this Universe is drained; the entire canvas of the starry skies seems to slowly being ripped apart on the seams.
The realities of this Universe weakened, wavered and slowly cracking and is about to break.
The Palm was not yet shoots out but just by bringing his palm out, there is already this kind of effect.
Azief could felt the power even when he was in the form. This was the ability that he gets when he was passing the Blissful State Trials.
And now he is seeing the master of the art to show him the way. If Loki knows that Azief passed and learned all this technique, he must have ben shocked.
Because while it is true Azief did tell Loki that he regretted not passing the Six Trials of Azul, he did not tell him the whole story.
He only told Loki that he regretted not passing because if he passes that trial, he could complete his grand Path
But he never told what Azul abilities are to Loki.
