World view setting
1. **Three Realms of Reincarnation**: The triangular balance system composed of the heaven (eternal fairyland), the human world (Xuanhuang Continent), and the netherworld (nine abyss) was created by Xingtian, the god of war in ancient times, who split the chaos.
2. **Gate of Eternity**: A huge bronze door suspended in Guixu of the East China Sea. The door is engraved with the eight-character mantra "The sky and the earth are black and yellow, and the universe is prehistoric." Every thousand years, it will spit out the "black and yellow gas" that contains the power of creation.
3. **Curse System**: Before being sealed, the Nine Nether Demon Lord imposed a "blood moon curse" on the three realms. Whenever the blood moon is in the sky, all monks will fall into a state of madness.
