In the Magus Alliance and throughout the Magus Universe, The Nephilim Faction was known to possess the most extensive knowledge of the illustrious light element.
That, coupled with the fact that Jinkan was the next in line for the throne of the prominent faction. She had to have at least achieved mastery on the subject to be deemed eligible for her current status.
The fact that the light element was capable of manifesting the 8 other elements was not exactly unknown, but such feats still required the caster to have a high proficiency in the element as well as comprehension of the Law of Transmutation.
Most of the people who understood what Jinkan did nod their heads in recognition of her abilities, while the other layman spectators showed extreme excitement seeing how she was able to calmly respond and deal with the deadly attack Klea threw.
Another defeat, more chapter coming soon, thank you for reading
