The Spirit Transformation Array was one of the necessary arrays for forging high-level equipment.
Since the energy of the material itself was not strong, if one needed to cast Epic-grade or above equipment, one had to inject a huge amount of Essence into it.
The value of Epic Essence was usually around one million, while Legendary Essence was priceless, usually more than five million.
Essence was a miracle of nature, containing an immeasurable amount of energy. However, it did not fuse with equipment, and could only be transferred to equipment through the Spirit Transformation Array.
The Spirit Transformation Array was also a field of arrays with different levels.
Wu Mo had only drawn a Tier 1 Spirit Transformation Array in the past, but Legendary equipment required at least Tier 2 arrays.
Thus, this segment was also a test for Wu Mo.
