Who are the three demons in Xuanyuan Tomb? What is the origin of Xuanyuan powder three demons?

The origin of this Xuanyuan tomb is also relatively simple. When I was mending the sky by the goddess, the foreman couldn't reach the island, and the sky fell to the northwest. In addition to mending the sky, Nu Wa also cut off four feet of a giant turtle as a pillar of the sky. A turtle can also be called Xuanyuan. So the place where the giant turtle was buried after death was called Xuanyuan Tomb.

The nine-tailed fox, the nine-headed pheasant essence and the jade pipa essence are three demons, that is, Nu Wa arranged for them to wake the tortoise in the tomb and practice at the same time, thus becoming their cronies.

But then again, Xuanyuan Huangdi is a saint, one of heaven and earth people, Huang San. How did he get involved with some little monsters? In addition, even Nu Wa Niangniang regularly goes to Huang San to worship. Huang San also realized the deification and even participated in it. Why?

First of all, Yang Jian went to Huang San for medicine many times. Second, Bai Jian, the first deified deity in the list of deities, never participated in the war between Chao Ge and Xiqiao, nor did he participate in the struggle to explain and intercept religion. He has always existed in the form of Yuan God, and the key white sword is a general under Emperor Xuanyuan. Therefore, almost all the delegates took part in a recruitment from heaven.
