There were different types of secret realms and spatial pockets.
Some, like the one Qingyi saw in the golden dragon statue in the land of the dragon people, were basically just a distortion of the interior space, making it larger than it should be.
Like entering a room that, from the outside, appeared to be twenty square meters, but inside, was over a hundred.
Others were like the Heaven-Defying Thunder Sword, existing on entirely different planes and whose only entrance was often linked to an artifact.
But there was also a third type: separate spatial pockets, often connected to a specific region.
They could be interpreted as a line that ran side by side with the central space, still under the primordial laws and connected to the central one, albeit inaccessible.
From everything Qingyi had heard in conversations about Auranys with Celestial, he was sure that her divine realm, the spatial pocket where she hid, was of the third type.
