The Myth of the Evening Moon

I don't know when. There are two types of people in the world. One type is the Xuanyuan tribe, which is huge in number. Under the leadership of King Xuanyuan, they live a seemingly peaceful life. The other type of people is unknown to outsiders and is recorded in ancient mythological books by the Xuanyuan tribe as the legendary demon tribe. Legend has it that the demon tribe has a sparse population and full autonomy. The legendary demon clan is not the demon clan, but the Dream God Clan. The Dream God Clan people are peace-loving, have no fight with the world, and just want to live their own small lives. The two worlds are not connected, and they lived in peace and harmony for a long, long time. Suddenly one day, the king of the Xuanyuan clan broke into the Dream God clan and destroyed the Dream God clan. From then on, there were no more legends about the demon clan in the world, and the peace of the Xuanyuan clan was no longer there.
