Two and a half years ago, after the Decree Bureau ambushed the Thunder Immortal Venerable and seriously wounded two people... the Thunder Immortal Venerable disappeared.
The Demon Cultivators of the Danai Dynasty, quivering in fear, once again resumed their old ways, causing the common people to live in misery, inciting the wrath of the heavens and the resentment of men.
However, under the regulations of the Danai Decree Bureau, Demon Cultivators could not harm lives but were only allowed to absorb a portion of one's Life Span, otherwise, they would face punishment from the Decree Bureau.
The good news was that mortals could survive, the bad news was that they couldn't live much longer.
