() It was subsequently noted that Huangdi was able to defeat Chiyou and ascend to heaven on the basis of the items bestowed by Jiutian Xuannü. Associations Warfare The association of this goddess with warfare is derived from the Longyu Hetu (), presumably produced during the Xin dynasty. This text describes the manifestation of the goddess herself in front of Huangdi () during his conflict against Chiyou (): Her intervention in warfare is a common narrative in Daoist texts, such as in texts from the Zhongshu Bu () in the Daozang ().

The Micang Tongxuan Bianhua Liuyin Dongwei Dunjia Zhenjing (), written in the early Northern Song period, gives an incantation associated with Jiutian Xuannü. By reciting this incantation and performing the paces of Yu (), invisibility to others was said to be achieved. In the Baopuzi (), written by Ge Hong (b. 283), the paces of Yu are described as elements of the divinatory system of dunjia (, translated "Hidden Stem") from which the immediate position in the space-time structure of the six ding
