Shang had comprehended two Concepts, and they weren't just any Concepts.
They were Concepts related to one of the two most mysterious Affinities in existence, Life and Death.
The Custodian only knew the first two Concepts of the Life Affinity, and he was one of the most powerful Mage Kings.
This showed how difficult it was to comprehend any Concepts related to these two Affinities.
How many people knew the first two Concepts of Death?
Well, how would one even go about learning about them?
They would need to interact with a lot of Death Mana without dying themselves.
Additionally, the comprehension of these Concepts was also very strange.
While any other Concept could be explained in words and with logic, these two Concepts couldn't.
It was just a feeling.
It kind of was a mysterious feeling of resonance.
