In this secret realm, the land masses are piled on top of each other to make a many-floored building with each floor the size of a large continent.
There are spaces between the layers of land. People come and go within the spaces between the layers. This is why there is a layer of land far above his head and why there is a layer of space beneath the land that he is standing on.
This arrangement makes full use of the space within the secret realm. One layer of land is bigger than Aries. With seven such layers piled up in the secret realm, one can confidently say that the total land area in the secret realm is at least seven times larger than the total land surface of Aries.
It is at least seven times bigger because the landmass in the middle layer of the spherical secret realm is more than two times larger than Aries.
