The Strange Case Files: A Ghost Realm Detective

During the Yuanhe era of the Great Yong Dynasty, the boundary between the mortal world and the netherworld began to weaken. Strange entities appeared everywhere, and people trembled at the mere mention of ghosts. The authorities established the Bureau of Yin and Yang to handle supernatural cases, but corruption and incompetence left most of them unsolved.

- The protagonist’s golden finger: the Underworld System (categorized as a “face-slapping/Scum-Tormenting System”). After binding to its host, the System issues a mission automatically every three days, such as “Find and exorcise the evil spirit causing trouble within three days” or “Stop the corpse demon from breaking out of its coffin within seven days.” Mission difficulty determines the rewards: Yellow, Black, or Earth grade. Completion affects the quality of the reward, while failure triggers “Netherworld Punishment,” ranging from serious illness to damage to the soul. The System interface includes “Yin Virtue” (which determines whether higher-level missions become available), “Ghost Sight” (which can reveal traces left by ghosts for the time it takes half an incense stick to burn), and a “Talisman Vault” (for storing exorcism talismans).

- Power progression: There are no fixed cultivation realms. Completing missions gradually unlocks the scattered volumes of Records of Netherworld Cases (nine volumes in total, each containing the weaknesses of strange entities and secret exorcism techniques). Reaching 100, 500, and 2,000 Yin Virtue respectively unlocks the “Judge’s Brush” (which can write a ghost’s name and summon its soul), the “Wuchang Shackles” (which bind yin souls), and the “Reincarnation Mirror” (which reveals the karma of past lives).
