The background of the Republic of China + female forensic psychic + the mystery of the identity of "civil servants in the Yin and Yang Realms". The heroine can touch the relics, see the last memory of the deceased, and possess the corpse of the "abnormal death" to complete the case. However, her life will be shortened every time she channels the spirit, and the resentment on the corpse will erode her sanity. What's even more bizarre is that the more she investigates the case, the more she discovers her true identity. She is a baby girl who was supposed to have died in a murder case thirty years ago.
