Huangji Jing: Entering the Tao Through Sound, Transcending the Era!

The universe is not eternal, but is cyclical with one element (129,600 years), from "open things" to "closed things", all things come and go, and the cycle begins again and again. When the one yuan is about to expire, the heaven and earth enter the catastrophe of closure, yin and yang are reversed, the laws collapse, all the ways die, everything returns to chaos, and a new yuan begins. The world doesn't know the truth, only the oldest inheritance vaguely records: At the end of the Yuanhui, only the "transcendants" can break out of the cycle and survive to the next Yuan!
