In a world where practitioners control the mountains, control the wind and thunder, and regard ordinary people as nothing more than grass and grass; in an era when the dynasty is decaying, there are many clans, the shadows are moving, and troubled times are about to begin. Ding Yan, a young man from a humble background who joined the Demon Cult, accidentally came into contact with ancient secrets during a life and death crisis.
What he inherited was not the glorious righteous path, but the annihilation inheritance belonging to the peerless strong man who was both good and evil - the Lord of Nine Netherworlds. From then on, he had supreme power, but chose to walk on the boundary between light and darkness. Far away from the rivers and lakes, outside the court, he quietly established a secret organization - Jiuyou Pavilion, which only fought to protect the survival of mortals. Players from all sides of the big chess game that day made their moves one after another. He became the "variable" hidden in the deepest place, trying to light up a glimmer of light for mortals in the long night with a cluster of flames ignited from the Nine Netherworld.
When the flame of Jiuyou ignites, what kind of future will it illuminate? Troubled times have arrived, and the guardian of the night quietly appears!
