Ghost, Why Are You Still a Ghost?

In this world, humans and ghosts coexist. Ghosts have spiritual identities, residences, and laws that cannot be touched; out-of-control resentful spirits, ghosts without a name, and monsters are handled by the Spirit-Suppressing Detachment. The cases dealt with here are no ordinary cases: dead people who work for others, missing persons hiding in mirrors, nameless spirits who can tamper with memories, monsters who wear human skin and sneak into the city. An Wu comes from a Zhenling family, and he has been able to see ghosts and understand ghost stories since he was a child. Tomorrow, he will officially enter the Zhenling detachment. But there is a female ghost beside him that shouldn't exist.
