In the midst of the battle, Shu-Ting realizes that he has entered the "black hole" in the heart of Ling-ying, and that his inner demon has merged with it. He realizes that the "dragon pool meditation" is a form of meditation that will let the "pureest people" and the "most wicked people" pass through. He also realizes that his enemy is his enemy as long as he gives his body to him.
