Black Sun Prison, the Empire’s forbidden zone of thought, houses the most insane, dangerous, and brilliant criminals on the continent. Lu Yuan’s job is to observe the prisoners’ “thought sandboxes” day after day, recording their deranged dreams and mutterings to prevent thought contamination from spreading. After ten years of this, he has grown accustomed to living beside madmen and staring into the abyss.
He has no idea that this monotonous job will bring him an unexpected, one-of-a-kind gift: his mind has become a living “Prison of Ten Thousand Sins.” The fragments of thought, lifelong knowledge, and even the mad obsessions of countless forbidden criminals have all become weapons he can use whenever he wishes. He can read people like a “trickster,” scheme on a grand scale like a “mastermind,” and make cold, ruthless decisions like a “tyrant.”
When a prisoner codenamed “Great Sage” leaves behind a deadly riddle pointing to the highest levels of power and pushes him into the vortex of a carefully planned conspiracy, Lu Yuan is forced to leave behind his cautious life as a prison guard and embark on a thorny road to survival.
To protect himself, he plays the schemer; to stay alive, he becomes a villain. Within the prison’s tangled hierarchy, he matches wits with his superiors, tangles with secret agents, and even engages in deadly games with the colossal forces lurking in the shadows. He may be the most inconspicuous grain of sand in the prison, but with the wisdom stolen from the minds of countless madmen, he will shake the foundations of the entire Empire.
When Lu Yuan opens his eyes in the darkness, countless mad souls stand behind him. He may still haggle over an extra ration, but his chessboard is now the entire Empire.
