Is “Yuanshi Tianzun, the leader of the Chan sect, holds the Investiture of the Gods and sends Jiang Ziya down the mountain to assist the wise ruler.” true?

The Investiture of the Gods constructs a grand celestial system, concretizing Yuanshi Tianzun, one of the Three Pure Ones in Taoism, as the 'leader of the Chan sect' residing in the Jade Void Palace on Kunlun Mountain, and it is he who orchestrates the entire enterprise of the Investiture. As the highest deity in the Taoist pantheon, the belief in Yuanshi Tianzun took shape during the Wei, Jin, and Northern and Southern Dynasties, a thousand years after the Shang and Zhou eras. The Records of the Grand Historian records the Battle of Muye without any conflict between the Chan and Jie sects, and the plot of Yuanshi Tianzun manipulating the change of dynasties is purely a fictional setting of the novel.
