How did the mythical Twelve Ancestral Wizards die?
Extended data:
The Master of the Twelve Ancestors is set in the online novel "Buddha is the Tao". There is no so-called granddaddy in Shan Hai Jing and even in all ancient books in China. According to legend, Pangu split chaos with the banner of Pangu, collected fire and geomantic omen with Taiji, separated turbidity and dried Kun, and created the world, and endlessly evolved six divisions in the wheel of karma. Pangu was unable to support the power of creating the world. The Yuan God created the world in Sanqing (Taishang Laojun, Yuanshi Tianzun and Tian Tong). Most of Xue Jing became twelve ancestors, and a few of them circulated in the six divisions of the wheel of karma.
The relationship between the Twelve Ancestors and Pangu is thoroughly remoulded, not a parent-child relationship, but a new person and thing derived from Pangu's corpse. Although the ancestor mage is an authentic Pangu (not a descendant), he is not Pangu, so he does not enjoy the essence and three treasures of Tian Kai. He is just a younger brother of his sister.
