Lu Ming, a 28-year-old programmer, died suddenly while working overtime. He unexpectedly passed the underworld civil service examination and became an assistant judge in the Reincarnation Department. With his knowledge of modern technology and programming skills, he has repeatedly solved strange cases in the underworld: from the disappearance of Internet celebrity ghosts to the hacking of the Book of Life and Death system, from the theft of Meng Po soup formula to the riots in the eighteenth level of hell. During the investigation, Lu Ming gradually discovered that there was a shocking conspiracy hidden deep in the underworld to subvert the order of Yin and Yang. During the day, he works in the Yangjian Technology Company (borrowing corpses to resurrect souls), and at night he returns to the underworld to solve cases, dealing with classic ghost characters such as the King of Hell, Meng Po, and Black and White Impermanence, and uses modern thinking to solve ancient ghost problems.
