A thousand years ago, the demon world was divided into 12 areas, but there were 13 demon kings. Among them, White Feather and Black Feather share control of another world. This Black Feather hardly cares about anything, and no one except Bai Yu has seen him.
However, due to the power struggle among the demon clan, Bai Yu's safety was endangered. At this time, Black Feather appeared on stage for the first time. He killed the six demon kings who had caused trouble and cast the greatest curse in history.
Not only did he seal the passages between humans, demons, and spirits, he also sealed himself.
The time limit is one thousand years.
