The founder of Jiutian Dangmo, also known as Zhenwu Emperor (Xuanwu Emperor), was the folklore of the Warring States Period at the latest. It turned out to be a patron saint, and his status was not high. It is just one of the four gods (Qinglong, Baihu, Xuanwu and Suzaku are four stars, guarded by four gods). In the Song Dynasty, because the emperors of past dynasties generally believed in Taoism, the status of Zhenwu Emperor, who had been integrated into the Taoist system at this time, was constantly improved and his deeds were gradually enriched.

For example, he was given a life story file in the book "Biography of the Buddha's Early Martial Arts". He is the prince of the pure music kingdom, born in the pure music palace, born with God, and lucky. When he grew up, he was very brave and devoted himself to practice. He vowed to rid the world of demons and refused to inherit the throne. After meeting with the superior, I got the secret and went to Wudang (Taihe Mountain) to practice with my sword.

After the successful completion, the Jade Emperor Buddha ordered the Imperial Town to administer Xuanwu and renamed it Taihe Mountain Wudang Mountain (The Journey to the West basically followed this story). He seems to be a natural god, good at exorcism. In the Ming Dynasty, Prince Judy was arrested for improper position. Jingnan political reform? To seize my nephew's throne, I need the blessing of God, so I instructed the literati to fabricate some wonders and add some auras to their heads. Therefore, there is a legend that the prince was able to gain the throne because of the real help of the phantom (rise) of Emperor Wu, which may refer to the theocracy of the monarch.

As a reward, after the prince was promoted to the throne of the Ming Dynasty, he issued a document to designate Zhenwu as? The innocent god of the Arctic town, the mysterious god? And built a big temple in Wudang Mountain. Due to the deliberate promotion of the superstructure and the influence of the upper and lower classes, Zhenwu belief reached its peak among the people. At that time, there were many believers, and Zhenwu Temple blossomed everywhere. The Journey to the West was written in the Ming Dynasty, when Zhenwu's status was already quite high. For example, Zhu Bajie has been a demon for two or three hundred years, and he still remembers it. He is proud to be a colleague of Zhenwu Emperor, and he always praises everyone when they speak.
