Du Wanli did not save the hunchback, but because the hunchback had now exposed the tricky schemes of the Songshan Sect, which was also of great use to his Five Poison Sect. That was why Du Wanli took action, helping the hunchback to block Bei Wei's palm strike, and allowed the hunchback to take back his conical hat, under which the four supposed loose cultivators from the Songshan Sect were instantly revealed.
Everyone present was flabbergasted. Some people hadn't expected that those causing a commotion in support of Bei Lengshi as the ruler of the Ancient Martial World were all actually Songshan Sect disciples in disguise. This was utterly shameless, utterly faceless. They weren't afraid of being ridiculed by all martial artists. Of course, this also showed the conspiracy of Bei Lengshi of the Songshan Sect; he was unscrupulously terrible in pursuit of his goal.
