Nine Yang Cave Heaven!
The so-called Nine Yang Cave Heaven is a very special Holy Land for cultivation within Du Yue Heaven Palace.
Like all the other various blessed grounds, entering the Nine Yang Cave Heaven also requires spending an enormous amount of Contribution Points.
Each time, one billion!
Inside the Nine Yang Cave Heaven, the density of nature's spiritual energy has already reached an unimaginable level.
No, it should be said that this is no longer merely nature's spiritual energy; it can even be called Immortal Spiritual Energy!
Take the Immortal Pond of East Spirit Immortal Pond as an example. The Immortal Pond is already a rare Blessed Land Cave Heaven in the mortal world and has even given rise to a vast Holy Land like East Spirit Immortal Pond. Yet the grade of Spiritual Energy in the Nine Yang Cave Heaven is still far above that of the Immortal Pond.
