The Three Songs of the Fisherman did not have a fourth move.
Mo Yu stood silently by the window. Many Li Palace priests only saw the grace and power of Gou Hanshi's Three Songs of the Fisherman, but they did not see what she did. It was precisely because Gou Hanshi had exhausted himself too greatly in the match against Zhexiu that he had used his strongest three strikes as soon as the final match had begun. What he had sought was a speedy victory.
Of course, although Chen Changsheng had managed to dodge Gou Hanshi's Three Songs of the Fisherman through some incredible fluke, Mo Yu still did not believe that this youth had any chance of winning. The discrepancy in cultivation was not something that magical artifacts could completely make up for, much less cheap things like courage and their ilk. Since that threshold was there, it was impossible to step across it.
This threshold was called Ethereal Opening.
