It is said that thousands of years ago, when the White Snake flooded the Golden Mountain to save Xu Xianshui, one of the younger sisters of the Green Snake, the Golden Snake, also followed suit. The flood made them unable to control their fate, and the golden snake was stabbed by a scorpion spirit, seriously injured, and on the way to escape, was rescued by a black bull spirit. Under the careful care of the black bull, the golden snake gradually healed, and developed a relationship with the black bull, and both became husband and wife in the mortal world. The Black Bull Essence was originally the matchmaker between Dong Yong and the Seven Fairies, and the Jade Emperor was furious and ordered Erlang God to arrest the Golden Snake and the Black Bull to be punished in Heaven. The golden snake and the black bull will be punished to the mortal world, and will enter the demon realm to suffer, and will never be reborn. The Jade Emperor ordered the Seven Fairies to drink the water of forgetfulness to the two of them. Before leaving, the Seven Fairies took pity on the suffering couple, and while giving them a potion, they secretly gave a red plum blossom they had woven to the golden snake and a black rose to the black bull. And quietly blessed them, telling them that if they could pick the seven threads of soul flowers she weaved in the demon world, they would be able to recover their memories, and they would both practice into the seven threads of flower soul swords, become immortals, and return to the fairy world. These words were heard by the two magpie spirits around the seven fairies, and in order to become immortals, they stole the water of forgetfulness, came to the Bull Demon Mountain, made seven wisps of forgetfulness powder, and went to the mortal world to find the reincarnation of the golden snake and the black bull. After collecting the souls of the two princesses in the palace, the two magpie spirits parasitized in the flesh of the two princesses. When they were refining the seven wisps of forgetful powder, they inhaled some powder, and they all fell in love with Murong Kuan, the son of Murong Shang, the minister of the court. Murong Shang's father and son were strong in martial arts, practiced their own cloud sword spectrum, and had close contacts with Yang Wei, a minister in the court. At that time, Murong Kuan fell in love with Yang Wei's sister Yang Guichou. The emperor gave one of the princesses to Murong Kuan and one to Yang Wei. Murong Kuan and Yang Wei resisted, and Emperor Long Yan was furious and ordered the traitor Tang Jie to tie up the two of them in the Tang Mansion, intending to force them to get married. The two princesses who were refined by magpies put the prepared love powder potion in front of Murong Kuan, and they both wanted to become Murong Kuan's wife. Unexpectedly, Yang Wei drank a bowl of forgetful powder potion first, and died of poison on the spot. When the two princesses saw it, they drank half of the remaining potion and each had a toxic attack. In order to compete for Murong Kuan, the two of them killed each other, and the little magpie couldn't fight, so they collected Yang Wei's soul, and went to Yang's mansion to vent their anger, and the big magpie essence collected Murong Kuan's soul, and this is how the story began......
