When the
Yan emperor was leading his tribe and conflicts with Nine Li tribes led by Chiyou,
[1] the Yan emperor stood no chance and lost the fight. He escaped, and later ended up in
Zhuolu begging for help from the
Yellow Emperor.
[1] At this point the epic battle between Chiyou and the Yellow Emperor's forces began. The battle last for 10 years with Chiyou having the upper hand. During the Battle of Zhuolu, Chiyou breathed out a thick fog and obscured the sunlight.
[12] The battle dragged on for days while the emperor's side was in danger.
[7] Only after the Yellow Emperor invented the
south-pointing chariot, did he find his way out of the battlefield.
[7][12] Chiyou then conjured up a heavy storm. The Yellow Emperor then called upon the drought demon
Nüba (女魃), who blew away the storm clouds and cleared the battlefield.
[12] Chiyou and his army could not hold up, and were later killed by the Yellow Emperor.
[1][7] After this defeat, the Yellow Emperor is said to become the ancestor of all
Huaxia.
[7] His followers were forced to live in the mountains and leave their Li kingdom.
[10] After Chiyou's death, it is said that it rained blood for some time.
