Ren Baqian was still hoping for Qingyun Sword to surrender.
As the head of the hidden village and the leader, it would play a big role in calming down Tianjing Basin if he surrendered.
Furthermore, Qingyun Sword wasn't an ambitious person. His greatest wish was for the people of Tianjing Basin to be free.
With regard to the various sects, Ren Baqian actually didn't desire to exterminate them.
The people that he had yet to decide about were from the three major factions.
This was because the members of the sects were dispersed all over the basin, didn't have political power, couldn't influence the commoners, and had no links to their ancestral temples. Even if they were left behind, they wouldn't cause much upheaval.
