Only the Gu Family seemed to waver, somewhat oppressed by the two families, and the disintegration of the Gu Family was also very coincidental. I can basically conclude that it was the Ling Family and the Dugu Faction intentionally pressuring the Gu Family, while the Court took advantage of the situation, causing the Gu Family to collapse from within.
The Court did not win over the Gu Family but instead cooperated with the Ling Family and the Dugu Faction to eliminate the Gu Family, with one goal in mind: to numb the Ling Family and the Dugu Faction. After all, these two families are deeply rooted in the Yun, Qing, and Liang Three States, and it's impossible for them to be completely unaware of Yang Yuzhi's plotting.
