Well, although Divine Energy Capability was very important for a cultivator, the same could be said for their control over it. This test benefited those with high amounts of Divine Energy, sure. However, it would be useless if one didn't know how to control it properly.
Control might not look like it had anything to do with the amount one could store. However, that was wrong. Control was directly linked to it. The cubes accepted Divine Energy to go up, but how one would distribute it inside the cube, how much, and at what rate...suppose a cultivator has 100 points of Divine Energy while another one has one 90. The guy with 100 spends 10 points of Divine Energy per hour. While the one with 90 points can do the same thing, spending only 8 points per hour. In the end, who has the best capability? Obviously, it would be the guy with 90 points since the guy with 100 points would run out of Divine Energy earlier.
