sect master of the North hall, I don't know if you've heard that the patriarch of the north gate of your Sky Mansion and my sect's patriarch once jointly created and perfected a set of Xuan skills.
"It's said that this Xuan skill is extremely powerful and can dominate over earth level Xuan skills. It's an existence that ordinary earth level Xuan skills can't compare to. However, this Xuan skill can only be cultivated by two people at the same time and they must have a very good understanding of each other. Otherwise, it will not be able to be used."
back then, the ancestors of our two sects used this set of profound skill to become famous in the sky Mansion region. The sect leader of The White Tiger sect explained in detail.
