Although Hou Yuxiao had long suspected the Rakshasa Holy Sect's conquest of Bingzhou, he inevitably fell into a state of anxiety upon confirming the news.
This anxiety had two layers of reasons.
One layer was due to his deep-seated fear of Sikong Yue.
In truth, he's only met Sikong Yue once. Last year's encounter in Nanping Prefecture was merely seeing the projection left on Zhantai Wuyuan's body by Sikong Yue, so it doesn't count. However, that single meeting was enough to make Hou Yuxiao wary until now because, up to this point, Sikong Yue is the only one who can truly see through the Good and Evil Divine Lotus.
Moreover, although they've only met once, Sikong Yue's utilization of the Hou Clan is everywhere. Take the recent pacification of Nanjiang and Jianye Prefecture by the Hou Clan, for instance; it's all part of Sikong Yue's planning behind the scenes, and the key point is that she succeeded in both cases.
