The royal family, with the imperial court and its officials as its core, ruled the world. Corpse chasers are a special group of people who make a living by driving away corpses. In addition, there are Jianghu grass bandits, they are unemployed vagrants and people who make a living in the Jianghu. Limin refers to the people of other ethnic groups in the world.
The demon clan includes stone demons, wood demons, beast demons and human souls. These monsters are not born like this, but are transformed from the cultivation of giant beasts in the world. When they grow to a certain stage, they can become demons through practice. Stone demons are transformed from boulders, wood demons are derived from plants, beast demons are transformed from birds and beasts, and human souls are formed from resentment after death. Among the demon clan, there are also orthodox devils, who are the core force of the demon clan.
Killing invisible, winning thousands of miles away, they are ordinary flesh and blood, but they have the body to subdue demons. The existence of the Nine Clans is like a powerful force, deeply threatening the peace of the demon world. Since the beginning of history, the demon world has been constantly planning and trying to eradicate the nine tribes in order to eliminate those who catch demons from the world. In this way, the demon world can run rampant without restraint.
However, there is a huge conspiracy hidden behind this. The existence of the nine tribes is not only a threat to the demon world, but also the key to balancing the three realms. Their mission is to protect humans and fight against evil. But the demon clan attempts to break this balance and plunge the world into chaos.
