Among the many Taoist treasures silent in the world, the most mysterious and powerful ones are actually two little-known beads, also called Yin-Yang Pearls. They are created by gathering the energy of Yin and Yang between heaven and earth. It is said that they have the ability to control all ghosts and transcend life and death. But if you get it, If the human mind is not right, it will cause a catastrophe in the world; there is also a legend that such a powerful yin-yang orb is actually the door key to the five realms of immortality, demon world, human world, ghost world and demon world. Once you hold it, you can travel through the five worlds at will and obtain the secrets of the five worlds. The Yin-Yang Pearl has been secretly guarded by a secret Taoist sect. They believe that the Yin-Yang Pearl is the key to maintaining the balance of yin and yang in the world. Once they leave the Yumen Mountain where they practice, the world will be unbalanced and the demons will dance wildly.
