Is “The Shang general Kong Xuan possessed the Five-Color Divine Light, which was invincible, and his true form was a peacock, later subdued by the Daoist Zhunti.” true?

In the「封神演义」, Kong Xuan is depicted as a top-tier combatant, whose five-color divine light can brush away anything. Chapter 071 of the novel records: “准提道人将孔宣用丝绦扣著他颈下，把加持宝杵放在他身上，口称：‘道友，请现原形！’霎时间，现出一只目细冠红孔雀来。” This plot design directly borrows from the Buddhist belief in the Great Peacock Ming King. The「史记」records that the Shang-Zhou war involved only mortals on both sides, with no mention of a peacock spirit serving as a general. Kong Xuan's deeds are entirely fictional creations of the novel.
