Under the world
The demon clan rises, the divine clan hides, and the seven clans are in chaos.
Each tribe has its own evil intentions and everyone is in danger.
When etiquette breaks down and music collapses, how can we save the world?
A prince in trouble, a descendant of the demon clan, a grassroots citizen, and three chosen sons, with their own ideals and driven by fate, embarked on the road to salvation.
Heaven will confer great responsibilities on this people.
