Wang Qisheng and Li Qianqian's marriage is an internal alliance within the Xuanqing Sect. Although the Yang family is now one of the Twelve Families, it is still considered an outsider to the Xuanqing Sect.
And although Yang Qinting is a disciple of the Xuanqing Sect, he is even more so a descendant of the Yang family.
Many descendants of major families join the three major sects, but few can hold high positions within them.
This is because the three major sects are also wary of the families growing too powerful, thereby affecting the sects internally.
Take the Beishi family for instance; the reason why the Master Family split into the Beishi and Nan Shi families was because the Master Family was becoming too prominent.
And since the relationship between the Master Family and the Xuanqing Sect was too close, the Xuanqing Sect couldn't completely eliminate the Master Family, so they simply split it and let the Nan Shi family come under the governance of the Wuxiang Sect.
