Kong Xuan, the posthumous child of the Phoenix Clan Leader, was the first peacock between Heaven and Earth.
During the First Epoch, Kong Xuan became a disciple of the Jie Sect Hierarch, Tongtian Saint, devoting himself to the cultivation of the Upper Qing True Essence and Upper Pure Immortal Skill, reaching the pinnacle of the Sub-Saint realm. Later, due to the Chan Sect, he was implicated in the Divine Enthronement matters and was heavily injured in an ambush by Saint Zhunti at Golden Chicken Ridge, eventually taking refuge in the Western Pure Land and becoming the Peacock Great Ming King.
In fact, regarding Kong Xuan, what is most widely circulated in later generations is the act of Slaying Saints! However, according to what Li Qingming discovered later on, Kong Xuan Slaying Saints was clearly a joke.
Therefore, the true cause of this right and wrong can only be known by asking Kong Xuan himself.
