72 The Reason Why There Are So Many Swords in the Immortal Cultivation World

It was indeed the authentic spirit bloodline that would always be accompanied by thunder and lightning when it appeared!

Fang Jinyu's benefits weren't limited to it. Other than the different attributes of the spiritual roots, there were also differences in their aptitudes. There were four classes, A, B, C, and D. In addition, each class was subcategorized into two classes denoted by "+" and "-".

Initially, after Fang Jinyu used the Mortal-Transmutation Elixir to remove the fire element from his spiritual roots, his wind attribute and lightning attribute spiritual roots were rated B-. However, his lightning-attribute spiritual roots directly upgraded to A after he refined the purple-volt spiritual fire!

Fang Jinyu even got an A+!

The improvement of his spiritual roots cleared Fang Jinyu's mind. Everything that he hadn't been able to understand before, as long as it was related to the lightning attribute, was now clear in his mind.
