Qi Yue mentioned Qixing during the previous Contract Garden gathering, openly revealing Qixing's collaboration with the Cyan Deer Tribe.
All of this, Qi Yue had already informed Fang Mu about.
Qi Yue advocated for cooperation between Guardian Beasts and humans in developing the Dimensional World. Anyone with insight could see whose agenda he was truly supporting.
With Zhuo An's current strength, he was already capable of participating in the meetings of the Emperor Beast Court. Even if Zhuo An's response was slower, he undoubtedly realized that Qi Yue had disclosed the news of the discovery of the Dimensional World Channel entrance to Qixing.
These details had previously been kept from Fang Mu even while Zhuo An was under Fang Mu's control. Zhuo An feared that, upon learning of these matters, Fang Mu might hold grievances against him.
