Chiyou launched an army to attack Huangdi, and Huangdi ordered Yinglong to attack the wilderness of Jizhou. What's the meaning?

Chi You was attacking the emperor, and the emperor asked Ying Long to sneak attack him in the plains of Jizhou.

Chiyou was the chief of the Jiuli Tribal Alliance in ancient times, and also the leader of the Ox Totem and Bird Totem clans. He had 81 brothers and about 81 clans and tribes, all of whom had extraordinary abilities and were brave and good at fighting. Chi Youben and Emperor Yan belonged to the same tribe, but due to conflicts, he left Emperor Yan to develop on his own. Legend has it that Chi You had a strange dream and was ordered by God to conquer Yan and Huang. In his dream, he fought with Emperor Yan and defeated Emperor Yan.

The Yan Emperor received a battle invitation from Chi You and was worried that he might be defeated, so the Yan Emperor and the Yellow Emperor joined forces to fight against the enemy. As expected, Chi You led eighty-one brothers to reorganize the coalition forces and go north to resist the Yellow Emperor's tribe, and started a fierce battle in Zhuolu. Because the Yanhuang tribe introduced and independently developed various copper and iron weapons and made good use of terrain, weather and other conditions, they defeated Chi You. In the end, the Yanhuang tribe defeated the Chiyou tribe again and integrated the people, thus starting the glorious history of Chinese civilization.
