Karma Code: Files of Eighteen Hells on Earth

Before retiring, an old Zen master handed over his clinic to the psychiatrist Ming Xin, leaving behind a cabinet of case files classified according to the "Eighteen Prisons". Each file is a story of hell unfolding in the human world, and the nineteenth drawer is empty with the label reading "The End." Later, people learned that the old Zen master's lay name was Hui Hai, and he was the original algorithm architect of the "Hippocrates-3" system.
