At this moment, Yin-Yang Harmonious Emperor had already gone somewhat mad. Under normal circumstances, even if beaten to death, he would never have conceived such a frenzied notion. For an Imperial Sovereign to want to kill a Celestial Venerable was simply a monstrous act of defiance.
Back when Ye Xiwen had merely killed Heaven Devouring Demon Emperor, who had only just become a Celestial Venerable, he had already faintly provoked the displeasure of all the Celestial Venerables between heaven and earth.
