In order to change her destiny, she embarked on the arduous road of cultivating immortality. By chance, she obtained an ancient sword and accidentally awakened the ancient sword spirit Mo Yuan in the sword. With Mo Yuan's help, Yun Qing overcame many difficulties and gradually revealed his amazing talents. At the same time, she also made many friends, including Bai Qingyu, the chief disciple of Qingyun Sect, and Su Waner, who came from a family of medical practitioners. However, the world of cultivating immortals is not peaceful, and there are undercurrents. The appearance of Ye Wushang, the young master of the demon world, broke the peace of the fairy world.

In the confrontation with Ye Wushang, Yun Qing gradually discovered the secret of his life experience and the responsibility he shouldered. In the end, Yun Qing relied on her tenacity and the help of her friends to defeat the evil forces, protect the people, explore the way of heaven, and attain the great truth.
