Thousands of years ago, the Heavenly Court Academy trained a group of bright and exceptionally gifted children. Later, Zhou Yi, the Azure Dragon, died for love. To bring Zhou Yi's soul back, Zhao Shu, the White Tiger, descended to the mortal realm to undergo trials and was reborn as Shen Haoxuan, a disciple of the Kunlun Sect. After enduring countless hardships, he finally joined the ranks of the immortals and resurrected Zhou Yi. Hundreds of years later, Zeng Lei, the Black Tortoise, fell in love with Yan Zhanyuan of Peach Blossom Spring. But because of a jade pendant, Yan Zhanyuan was trapped inside a barrier for ten years. Ten years later, Zeng Lei met Sima Xun, who possessed the other pendant, and reunited with Yan Zhanyuan. The two pendants then merged into the Yin-Yang Jade Ring. Meanwhile, Xiang Shuxie and the others from the Crescent Moon Cult had their eyes fixed on the ring, so with their friends' support, the group set out to protect it.
