After humans had expelled demons from the Alkaid World, they formed different families and sects. The Alkaid World had welcomed the age of families and sects since then.
The ninth-grade family or clan would rule over a city, the eighth-grade would rule over a county, the seventh-grade would rule over a state, the sixth-grade would rule over a kingdom, and so forth.
Chen Yang was transmigrated to this world with the Akido Pearl. With it, he raised a group of beasts with powerful bloodlines and even built a farm to lead the Chen family to achieve the title of the Saint Family.
