Back when his Divine Inner World was at Rank 1 Divine World, it only had a capacity of one billion units of Divine Essence of Nature.
Using anything above 50 percent of this Divine Essence of nature would partly damage the Divine Inner World.
Moreover, the recovery and regeneration of the Divine Essence of Nature of the Divine Inner World would be greatly affected and it would take years to get back to its original condition.
To turn the newly created Fire Elemental Spirit World into a Divine Fire Elemental Spirit World, nearly 60 percent of the Divine Essence of Nature was consumed.
However, there were no severe effects on the Divine Inner World before it was no longer a lowly Rank 1 Divine World but a Rank 3 Divine World.
According to the system, using 50 percent of the Divine Essence of Nature in the Divine Inner World won't be a problem and even 60 percent would cause no issues.
