"Many thanks for being my grindstone, Bai Hao. I've finally achieved my cultivation base breakthrough, and am a half-deva. I've been stuck in place for far too long now, and have you to thank. Therefore, in recompense, I will simply cripple your cultivation base, and won't kill you!" Gongsun Yi looked both excited and proud. Throwing his head back, he laughed maniacally. As he had said, he had been waiting for this day for a very, very long time.
The pressure he had felt from Bai Xiaochun during their fight had been incredible. Upon seeing the Undying Emperor's Fist in action the first time, he had been aware that he couldn't defeat it. But he was proud and confident, and thus couldn't accept that. Furthermore, there had also been the possibility that he could take the situation and use it to achieve a breakthrough!
