The Spirit Core of the altar has long recognized Rod as its master; as long as he approaches the altar, he can control it through his spirituality.
And the energy of the Star Marrow Altar comes from spirituality.
If there is no spirituality, one can also inject the soul into the Spirit Core.
The ancient gods once did this, which is why the internal space of the Spirit Core has so many monsters.
Due to the corrosion of numerous souls thrown into the core, the Star Marrow Altar previously functioned at a very low efficiency, yet still managed to condense such a magnificent Black Fog Wall.
This is why Rod is confident that he can carry out the "Eternal Sanctuary" plan.
Of course, Trolian's "Eternal Sanctuary" is not a separate space isolated from the world as originally planned by the ancient gods, but a highly efficient defensive strategy aimed at compressing the lengthy borders.
It not only has entrances and exits but can also continue to expand outward in the future.
