Long before the Tribulation of the Wu and Yao, the Two Saints of the West had tricked the ten Golden Crow crown princes into leaving the Tanggu Valley to wreak havoc upon the world. In the end, Dayi, a Great Wizard of the Wu Clan, shot down nine of the Golden Crows with his God-Shooting Bow. Only the tenth prince, Youwen, was saved by Eastern Emperor Taiyi, and was later sent by the two emperors of the Demon Clan to practice cultivation in Goddess Nuwa's Wa Palace.
The affair of the ten Golden Crow princes had been one of the primary catalysts that triggered the decisive war between the Wu and Yao clans.
When the Great War of the Wu and Yao concluded, the Two Saints of the West had gone so far as to abduct thousands of demons into the West in a single sweep, converting them into the Western Religion.
