148 Years ago, Zhu Yuming (the heroine) and her sister Zhu Shuyue secretly went down to the underworld and accidentally met Yu Yan and Jiang Sui. Later, they joined the Cangqiong Sect, the leader of the five sects, and rescued Ye Qixing. Several people grow up together and eliminate demons together. Then, Lord Ming secretly wanted to subvert the five realms, and at that time the five realms would destroy all living beings. When all the factions worked together but failed to defeat the Lord of the Underworld, the legendary sun and moon birds flew across the sky, sang a long cry, and transformed into two beautiful women. When the two assisted the factions in sealing Ming Lord, a long sword pierced the body of a woman. Then both of them disappeared into thin air and disappeared without a trace, leaving only Ming Lord's body sealed. Later, Yu Yan took over as the leader of the Cangqiong Sect and accepted the orphan Yuan Mingle as his disciple. The two went down the mountain to practice and met Qi Xing and Xing Yue. But soon, Ming Lord faintly revived, and what followed was the conspiracy behind it and the entanglement of several generations.
