Divine Essencefused Mountain is a mountain with a five-elemental power. It was used by Wen Qing and Ling Xiaofeng to cultivate the Divine Essencefused Light art to reach Deity Transformation stage.
Divine Essencefused Mountain looked like a pitch-black big rock around 500 to 600 feet tall with a wide base that tapered as it up toward the peak.
Divine Essencefused Mountain was discovered by one of Heavenly Star Sages, Ling Xiaofeng, in the Outer Star Seas. He witnessed this mountain erupting out from an underwater volcano. Only after extensive effort and help of many Star Palace's mambers, the mountain was moved to the Heavenly Star City.
Han Li refined it again with Greyish-White Stone Block, the stone block is practically indestructible.
Of course, even with his Spirit Engulfing Heavenly Flames, it wouldn't be a simple matter to melt these stone blocks. Otherwise, Han Li would've thrown in all three at once rather than only one.
However, even with just this one stone block, it would take around three or four decades to melt it into the mountain. If he'd done all three at once, then it'd at least require a century.
Integrated Five Extreme Mountain
in the final section of this Profound Heavenly Tool Refinement Technique, there were specific methods enclosed through which once could refine artificial Profound Heavenly Treasures. The other few methods all required materials that were either impossible to find in the Spirit Realm, like refined stars, or materials that Han Li had never even heard of.
Only the materials and refinement method required to refine this Integrated Five Extremes Mountain seemed to be viable in the Spirit Realm.
In order to use the refinement method, one had to at least be at the Body Integration Stage, and the materials required to refine this treasure were actual mountains. The materials of these mountains being Greatnorth Essence Light, Divine Essencefused Light, Five Elements Yin Yang True Light, High Zenith Azure Light and Vast Yin Stones. The corresponding mountains of the materials after refinement are the Extreme Greatnorth Essence Mountain, Extreme Essencefused Mountain, Extreme Five Elemental Yin Yang Mountain, Extreme High Zenith Azure Mountain and the Extreme Vast Yin Glacial Mountain.
Before traveling to the Vast Glacial Realm, Han Li makes his preparations. It is implied that Han Li gathered the materials and refined the Divine Essencefused Mountain into the Extreme Essencefused Mountain at the end of Chapter 1676.
