Ancient history records:
When chaos first opened, three realms took shape: the underworld, the world of mortals, and the realm of blue sky.
In the vast blue sea of the world of mortals, there are four continents distributed on them. Humans, beasts, Shura, and demons all live on them. They do not interact with each other and live in peace with each other.
Unexpectedly, the doomsday disaster 20,000 years ago caused the collapse of the world of mortals. The Demon Emperor and the Human Emperor disappeared one after another, but humans took the opportunity to invade the Demon Clan's territory.
Ever since their homeland was invaded by humans, there has been a lot of hatred between humans and monsters. Ethnic vendettas occurred frequently.
The blood descendants of the two clans, the half-demon clan, are the most unfortunate products of this chaos. Neither human society nor the demon world recognizes them. They had to become the meanest race on the continent, living a precarious life without seeing the light of day.
The collapse of the world of mortals also triggered fluctuations in the other two worlds. From then on, the Biluo Realm also opened its door to the world of mortals - races in the mortal world can enter the Biluo Realm through cultivating immortals or demons.
Since then, there has been a vigorous trend of spiritual practice in the world of mortals.
