He did not believe that any of his attack could slow down that hand. This is an instinct that he had cultivated along the years.
He instinctively knows that any of his attack would not work and probably would not even slowdown that hand and so he chooses to run
The kind of beings that dares to do this kind of thing must be some powerful being at the same level of Odin
Or even surpassing him
That is the only way that it could even ignore the causal effects that is present in all of those timelines and space.
Azief however is not interested in calculating the cause and effect right now.

This is the foreign energy that suddenly appears the moment that hand appears.
That hand wanted to capture him and probably it would have succeeded if not for this foreign energy that suddenly helped him
Azief notice that from the moment that hand sappers, all time and space around him seems to froze.
