The Upper Realm was sealed, leaving no chance for anyone to escape from this place.
One could break through the barrier with overwhelming force, but that was also advantageous for Ezekiel as that could give him the specific location of the enemy they were trying to find.

In the Southern World, there existed a small village. The village was insignificant to the point that many didn't even know about its existence. Only very few people used to live in the Village.
The Village was surrounded by a barrier of its own, but the villagers couldn't see that barrier. The barrier didn't stop anyone from entering or leaving the village, and remained invisible.
The only thing that the barrier did was to prevent the aura of the Gods from leaking into the area. It also made it impossible for anyone to spy on this place.
