In a world powered by magic crystals, the Monster Management Bureau controls everything. Magic crystal, this mysterious energy crystal, is not only the source of magic, but also a symbol of power.
However, hidden under the bright surface is a dark world full of conspiracy and betrayal.
Liu Qingming, an ordinary college student, was involved in a shocking conspiracy due to the mysterious death of his parents. His father was once a hero of the Demon Capture Department, and his mother was a core member of the Demon Control Department. The cause of their deaths seemed to be related to a mysterious organization called the "Abyss Council." In order to uncover the truth, Liu Qingming joined the Demon Capturing Department and became a trainee team member.
As the investigation deepened, he discovered that the tentacles of the Abyss Council had already penetrated into every department of the Administration. Anyone can become a pawn of the Abyss Council. At the same time, the demihuman alliance in Rusty Chain Town is also secretly planning a "decoding revolution" in an attempt to overthrow the rule of the Authority.
Dealing with various forces, uncover the truth behind the death of his parents, and at the same time prevent a conspiracy that could overturn the entire world. His choice will determine the future of this world.
