Actually, when the Seven Treasures Golden Banner was suppressed by Shi Sheng and others such as Li Hong and the two Xies were unable to subdue Shi Pi the Elder, Master Zun Sheng and the other two monks knew that their plan had failed.
Not only had this attempt failed, their entire life's plans had failed.
Master Zun Sheng knew that he could not enlighten Shi Pi, Bai Mei Zen Master also knew that he could not enlighten Zhu Youmu, and Tian Meng Zen Master knew that he could not enlighten the Xie sisters…
In fact, at that moment, the three of them should have left; they should not have appeared again because to do so would have been futile.
They only wanted to make one last effort, barely trying once more. Additionally, they wanted to collectively subdue the Ruyi Yin Thunder to prevent unnecessary casualties and catastrophe.
Shi Pi the Elder's reaction was completely within their expectations.
