So it turns out that the fundamental energy for enhancing strength isn't Life Energy but Spiritual Energy!
For Fang Mu, preparing pure Spiritual Energy was far easier than preparing pure Life Energy.
Fang Mu believed that with his own methods, he could provide sufficient Spiritual Energy resources for several God-Realm Experts.
Although Spiritual Energy is the most needed resource for God-Realm Experts, Elemental Energy and Life Energy are also indispensable, and the purer they are, the better they consolidate the absorption of Spiritual Energy.
Lian Dai didn't have any way to obtain pure Spiritual Energy, though indeed many substances in the ocean contained Spiritual Energy, especially the mineral veins discovered beneath the sea.
However, of the substances found in the sea that contained Spiritual Energy, only a very small part could meet the standard for God Territory Powerhouse consumption.
