Within minutes of sensing the advance of the great Sky Whale, the entire Minos group, except for Forrest, was focused on absorbing the vast amount of energy and laws being drawn into the area by the advancing beast.
Spatial Kingdoms were special!
When a God folded the space of a certain region and created one of these cultivation sanctuaries, the spiritual richness of such spaces was precisely the folding of space.
A God fold not only separated the area into a secondary space that was incredibly difficult to access, but it also acted as a collector of energy and laws.
At the "nodes" of the fold, all forms of energy from the Spiritual World were drawn into the Spatial Kingdom, like a drain that draws all the water in a bathtub toward itself.
In normal situations, this "drain" would simply cause the flow of "water" toward itself to be high. But reality changed a bit during relevant breakthroughs, like that of the beast in question.
