Yin-Yang Lightning Rune

A technique created by Zhou Yuan's master, Cang Yuan, to compress the user's genesis qi as Yang Thunder Qi while his/her Divine Soul as Yin Thunder Qi to the finger of each hand. Two black and white thunder rays are created, then they intertwined, forming a pair of super powerful and mysterious black-white thunder dragons. This was not an ordinary little Saint technique, but the fusion of Genesis technique and Genesis Rune. One was built upon Genesis Qi, while the other was based on Spirit.
