As Shui Xuan said before, in Western Xinjiang, Mu Shi is not the only family.
There is not only one Anxiang Pavilion that supports various major families. Yan Yin can disperse one Anxiang Pavilion, but cannot disperse people from other sects in the Western Xinjiang. Some of the various sects in the Western Xinjiang support some families in the Northern Xinjiang to conduct division and separatist affairs in this chaotic northern Xinjiang and seek their own interests.
In a world of great struggle, there must be people with great ambitions.
What the various factions in Western Xinjiang use are the ambitions of people with great ambitions in some families in northern Xinjiang.
