Pangu created the world, with the sky above and the earth below. After time accumulation, all things were sown, and a spiritual power containing strange energy was produced. Due to the cumulative influence of this special spiritual power over time, the heaven and earth were divided into nine heavens. Each heaven formed different species with different abilities.
Each heaven is a big world with different rules and the status of the creatures in it is also different. The status and abilities of the first to ninth heaven gradually increase.
In the first heaven, there is a world where all mortals and things gather. It is difficult for mortals and things to escape from here and enter the blue sky. Everyone here is a prison outside the sky. Mortals and things are inferior to pigs and dogs. They are lambs to be slaughtered. Their spiritual power is absorbed by great power and scraped cleanly across the sky.
