Dragon Abyss

In the third year of the Jingding era, the Ditang Rebellion has finally been put down. The court is in turmoil, and the forces of the martial world are stirring beneath the surface. Strange arts and sinister tricks have appeared, killing without a trace and leaving the people in a state of panic. In response, Liu Yuan, the newly enthroned ruler of Dongyue, establishes the Demon-Subduing Bureau, independent of the Six Ministries and open to extraordinary talents from the martial world. Its sole purpose is to hunt down criminals. The people of the martial world call its members the Black Feather Guards. Over the years, they have solved countless cold cases and mysteries...

Most people think they are ordinary guards, moving between the martial world and the imperial court, ordinary people who have solved countless mysteries. But in the eyes of demonic cultivators, they are thorns in their side, enemies they would do anything to eliminate.
