Chapter 50: Soul Crystal
The soul acts as a vessel, and the energy it contains is referred to as soul energy, which can be transformed into a **Soul Crystal**.
In the eyes of many wizards, soul energy is one of the most versatile energies in the multiverse.
Unlike elemental energy, which many beings cannot absorb, soul energy is universally absorbable and usable.
Soul energy can be said to be the most widely applicable energy across the multiverse.
A Soul Crystal, on the other hand, is the product of a soul dissipating after a life ends, a condensed form of soul energy.
Unfortunately, Soul Crystals are difficult to produce naturally; only certain special entities drop primitive Soul Crystals.
In most cases, wizards obtain Soul Crystals through artificial means.
To artificially create a Soul Crystal, a vessel must be prepared.
The most commonly used vessels are various gemstones.
What Sunan was currently doing was the process of artificially creating a Soul Crystal.
Amidst the unwilling shrieks, one ghost after another was drawn into the gem, causing its color to gradually shift towards gray.
