He Huan had once heard Qin Fengming say that a crystal would form inside the Nether Soul Ghostly Creatures of the Nether Soul Mountain Range. It was an energy-restoring crystal even more precious than top-grade Yin Stones.
That was the Nether Soul Crystal Stone, an energy crystal comparable to a top-grade Yin Stone. In terms of value, however, the Nether Soul Crystal Stone was far more valuable than a top-grade Yin Stone.
The Yin energy within the Nether Soul Crystal Stone was incomparably pure, with almost no impurities whatsoever. Although top-grade Yin Stones were extremely pure, they still could not compare. Cultivators did not need to circulate their cultivation arts to refine Nether Soul Crystal Stones; they could rapidly replenish the magical energy in their bodies without worrying about any drawbacks.
During an intense battle or while facing the Heavenly Tribulation, a ghost cultivator who absorbed energy from a Nether Soul Crystal Stone would recover magical power far more quickly than with a top-grade Yin Stone.
Looking at the crystal in his palm, He Huan was overjoyed.
The bodies of the Nether Soul Ghostly Creatures here were entirely different from those he and Qin Fengming had encountered upon first entering the Nether Soul Mountain Range.
The ghostly creatures Qin Fengming had encountered earlier had bodies formed from Yin energy with the Nether Soul origin as their core. A powerful strike could scatter them.
The ghostly creatures here, however, were still not flesh-and-blood bodies, yet they were clearly far more advanced than energy bodies. Their bodies were no longer condensed from energy and could not be easily cleaved apart.
He Huan was puzzled, but he did not investigate further. In his view, the mutation in the bodies of the Nether Soul Ghostly Creatures should be related to the environment and the
