From the 13th to the 14th level of the Qi refinement realm, the amount of spiritual qi required was enormous.
For ten thousand years, Lu fan had been quietly studying the indestructible demon body on the Lake Heart Island.
However, because Lu fan's spiritual Qi was now linked to the entire five Phoenix Great World, the Ninth Heaven, the Hunyuan immortal realm, and the five Phoenix continent... all belonged to Lu Fan's spiritual Qi collection range.
Although Lu fan's current level of heaven tier spiritual energy was unable to increase his percentage, with many cultivators breaking through to the Heavenly Emperor Realm and quasi-sage realm, the amount of spiritual energy that Lu fan could increase.., was incomparably vast.
Nie changqing, Bai Qingniao, and the others, who had obtained the beast ancestor's inheritance, were all cultivators of the five phoenixes. Therefore, Lu fan could also obtain a percentage of spiritual energy from them.
