Since the creation of the world by Pangu, there have been three realms: heaven, earth, and humans.
There are demon kingdoms in the human world, one in the east, west, north and south. Human villages are scattered around, with witches or wizards exorcising demons. The Nine Immortals travel in the three realms. There are also priests who are proficient in magic, and ghosts are scattered throughout the human world.
The demon kingdom is headed by the Western Kingdom, which has the largest territory and the strongest military strength. Followed by the Southern Kingdom, the Northern Capital and the Eastern Kingdom. The southern country is strategically located and rich in products. The northern capital is backed by the sacred mountain Wushui Mountain, with a giant lotus towering on the top. Therefore, the extreme cold has faded away from the northern capital, and it is as warm as spring. Although the Eastern Kingdom is at the end of the Four Kingdoms, its music and dance are famous all over the world.
People in the heaven are divided into nine classes. Among the nine immortals, the first class is the superior immortal. There are people who have experienced seven tribulations and become semi-immortals, with a life span of 800 years, an immortal appearance, and an immortal soul after death.
