My thought - The Night King touched Bran to confirm a blue hand-mark (imprinted his forearm) and knows exactly where they are and cannot protect the cave. The Children of the Forest had created the magic defense of the cave and the Wall. If Bran goes thru the Wall, the Night King will know where he is and will be penetrated. Seems Bran should not go thru the tunnel at Castle Black, just like Benjen would not go close the Wall – he knows. Bran will probably cause the dead army invade.

I believe a different theory about the Night King; he created from the Children of the Forest its first experiment (S6) to capture a Stark person (First Men since 12 thousand years ago) that becomes an evil “Stark” that escaped the Children of the Forest. Over the years the Night King had evolved his magic (just like the Children of the Forest improved with Benjen) to create more the White Walkers (babies) and arouse the Wights. I know this theory is completely different between show (HBO) version and the book version, because they could not have enough time and digestible this massive characters and complete plot. We could not expect them to make such an in depth perspective on the history of the book.
