In order to give Golden Lightning Palace technique to Xue Ren, Gravei had to arrange few things.
First, she had to make him her direct 'student' like Di Xun, and then, the ticket to Lighting Pool has been given to both of them.
Naturally, the patriachs had strong belief in their people and Gravei was one of these. Not only she was mother of young prodigy, she also had good talents herself to help the alliance in emergency case.
So they believed her judgement and the tickets has been given.
"Golden Lightning Palace gives you a lot of energy. It's huge boost that can store any lightning as it's technique made by the Lord Lightning God himself. The Lightning Pool you are going to enter with Miss Lightning Goddess is first step to see whether you are worthy of this technique."
"I get the idea."
