The Yellow Emperor and Chi You were invincible in nine battles. Chi You made a heavy fog that filled the air for three days and three nights. Huang Emperor's minister Feng Hou, inspired by the Beidou constellation, invented the compass and broke out of the fog. It is also said that the Yellow Emperor received the help of Xuannv in his predicament and made 80 Kui skin drums. Kui is a mythical beast in the East China Sea, "shaped like an ox, with a pale body and no horns". "When it enters the water, there will be wind and rain, and its light is like the sun and moon." , its sound is like thunder." Huangdi used its skin to cover drums and the bones of thunder beasts as drumsticks. "The sound can be heard for five hundred miles, and it is powerful to the world." The war between the Yellow Emperor and Chi You lasted for a long time, and the final decisive battle took place in the wilderness of Jizhou. "The Classic of Mountains and Seas: The Great Wilderness Bei Jing" records a legend, "There was a person dressed in Tsing Yi, named the female slave of the Yellow Emperor. Chi You launched an army to attack the Yellow Emperor, Huangdi ordered Yinglong to attack the wild areas of Jizhou. Chiyou asked Feng Boyu to fight against the strong wind and rain. Huangdi sent down the goddess of heaven and said that the rain had stopped, so he killed Chiyou and there was no rain in his place. ".
It reflects that during the battle, both sides used wizards to perform tricks first, hoping to conquer with the help of natural forces.
