Retrieving his thoughts, Qing Yu took a letter from within his garment.
This letter was sent from Yun Wuyue and contained information about an organization that Qing Yu had been paying attention to.
Cangsheng Sect.
Once outside Linchuan Prefecture, Qing Yu had intercepted Han Wenxin and discovered that this senior brother, who was deeply trusted by Sixth Prince Feng Chaonan, was a member of the Western Regions' Cangsheng Sect.
Later, while Qing Yu was secretly subduing medium and small families of Northern Zhou, he spotted the activities of the Cangsheng Sect again. They, too, were subduing those families in secret, clearly plotting something sinister.
Hmm... even though Qing Yu was also plotting something sinister.
However, at that time, the Cangsheng Sect had been avoiding conflicts with Qing Yu's Azure Dragon Association, thus no martial fights had broken out.
However, after the land and water rituals in Northern Zhou, the Cangsheng Sect finally showed its fangs.
