With these thoughts in mind, Qiu Tu roughly reconstructed the whole story in his mind.
As a thousand-year-old family, the Kou family definitely has a whole set of methods to collude with nobility and support those on the fringes of society.
Throughout history, aside from blood ties, the most reliable relationship is obviously "marriage alliance."
So, just as the Kou family used Su Wanqing to "entice" Qiu Tu, forming a strong connection with him, they undoubtedly also facilitated the marriage between King Kang and the Queen.
Even... perhaps because King Kang rose from humble beginnings, the Kou family's marriage alliance would be even more forceful.
Of course, for King Kang, gaining the support of an influential family via a marriage was certainly a profitable deal.
Thus, both sides hit it off and formally cooperated.
This led to the Kou family choosing King Kang, supporting him all the way, and helping him establish the Sixth Sanctuary.
