Until now, Aeon was able to create or merge the following classes of the Life Crystal:
1) Special Life Crystal: It contains twice the Life Energy compared to the regular Life Crystal.
2) Elite Life Crystal: It contains five times the Life Energy compared to regular Life Crystals along with a slight strengthening effect of the Life Seed Ability.
Note: Only the first three Elite Life Crystals will have that strengthening effect.
3) Unique Life Crystal: This class of Life Crystal, it surprisingly contains 10 times the Life Energy along with the strengthening effect on the Life Seed Ability for the first five Unique Life Crystals used by the cultivator.
With such features, how could Aeon be not curious about the classes above Unique Life Crystals?
After that, Aeon used the remaining uses of the [Crystal Merge] to merge the Low-level Special Life Crystals into Mid-level Elite Life Crystals.
