Today, the Divine Land Continent is completely submerged under the endless deep sea.
The immense water pressure has leveled most of the buildings, leaving no traces at all.
If it's a large city, because its walls and gates are constructed with hard stone bricks, some ruins are still left behind.
Wei Dongliu followed the low-lying areas of the seabed, struggling to identify the traces of the original river valleys, and upon finding a place with ruins, he could roughly guess which grand city it corresponded to in the outside world.
By groping so cautiously, he finally found the location of the ancient capital city.
In this mystical realm, all the terrain probably originates from the elder's own memories. If the ancient capital's Prison Dragon Well cannot lead to the Nine Serenities Underworld, or if there's simply no Nine Serenities Underworld in the mystical realm, then everything Wei Dongliu is doing would be in vain.
