According to records in the early Yuan Dynasty, Pangu, the father god, opened up the ancient world in the chaos, and evolved into the six paths of reincarnation, endlessly. After the death of the father god, the original spirit transformed into six ancient gods: Nuwa, Tianwu, Zhuyin, Bifang, Shuhai and Jubi. Most of the body's essence and blood transformed into the four heavenly emperors and auxiliary gods, and the rest transformed into mountains and rivers, and the essence of heaven and earth. Later, Nuwa created humans to live, and hunted souls to die. The cycle of life and death began, and the six paths of reincarnation were first formed. The gods each performed their duties, and the ancient world was on the right track. Therefore, the six ancient gods hid in the ancient world, and the emperors of the four directions created the nine heavens of the immortal world. Zibi and his wife Bi Fang even left the city of Kusi Naga to spread to the underworld. Hundreds of millions of years later, Haotian, the Lord of the Nine Heavens, succeeded to the throne. Eighty million years later, Jiuli, the Lord of the Demon Realm, went to the Nine Heavens and provoked a war between immortals and demons. The killing was very heavy. He was eventually killed by one of the four assistants, Zhongtian Ziwei Jiji, the great emperor of the North Pole. The immortal world won a great victory.
