Bipolar Firmament

"A lonely yin cannot give birth to a lonely yang, and a lonely yang cannot grow." The world is not composed of pure "justice" or "evil", but is intertwined by two opposing and interdependent original forces - "the power of the black pole" (representing order, creation, and light) and the "power of the underworld" (representing chaos, destruction, and darkness). A vast universe composed of countless floating continents and broken planes. In ancient times, the imbalance of the "two poles of Xuanming" caused the "catastrophe of annihilation", and almost all transcendent people perished.
