In the cave, Evan looked at the ten dark purple crystals in front of him with a pondering look on his face.
Six of the ten crystals in front of him were the size of a fingernail and were low-level void crystals. Three of the crystals were twice that size, indicating they were mid-level void crystals and the last dark purple crystal was nearly the size of a fist, a high-level void crystal.
While leaving the Tomb of the Ancient, Evan had found a total of six low-level, three mid-level, and two high-level void crystals.
Since he initially thought it would take him a long time to increase the rank of his core to the peak of Rank Two, he had decided to place one of the high-level void crystals inside the evolution space of the Rune of Evolution to further evolve it into a perfect-level space and void crystal.
