When Hongmeng was born, the world was divided into three levels, with gods at the top, humans at the bottom, and demons in the middle. The three realms do not invade each other. Humans and gods can degenerate into demons, and humans and demons can also cultivate and become gods. However, God is most concerned about the purity of "bloodline". Those who are not born with divine blood are often bullied. The devil has delusional ideas and wants to rule the three realms. Humans and Gods work together to kill them. Then, the devil fell to the ground forever. This story takes place five hundred years after the war. The remaining resentment of the devil wanders between heaven and earth, attached to the thousand-year-old epiphyllum supported by the gods, and accompanied by the epiphyllum.
Purpose: Orthodox bloodline is not a bargaining chip to measure the three, six or nine levels. People, gods and demons are all common people.
