In the eyes of such a supreme figure, this mortal world was insignificant in a way and same could be considered about the mortals. It could be seen that he had experienced innumerable eras and must have been to several worlds. It was as if he had crossed the river of time to appear here and it was fair to say that mortals wouldn't be able to comprehend such an entity.
He possessed the kind of imposing aura only known to have been displayed by great tyrants of the universe. The kind of suppression that could make everyone submit to this domineering figure, just like the legendary gods mentioned in fables.
Even if everyone knew that this was possibly not his main body but seeing such a supreme level figure standing right in front of them still made them have a feeling of prostrating themselves sincerely and worship him.
