It has to be said, people are fickle. The two who had previously been vehemently opposed to Pei Xuanjing's plan, had greatly changed their perceptions and attitudes. Not only did they intend not to reject Pei Xuanjing's plan, but they were thinking about implementing this method within their own forces first.
If this method indeed proved effective and reaped significant benefits, then the two might become Pei Xuanjing's biggest supporters for this plan.
As for the change in the two of them, Pei Xuanjing couldn't exactly see right through them, but he was able to sense their shift from subtle cues, and seemed to become more proactive.
Of course, if he knew that his speech had prompted the two of them to reorganize the changes within their factions, transitioning from a martial arts force to the sort of cultivation sect he had read about in novels in his past life, he wondered what his thoughts would be.
