At night in Fengdu City, there is always an inexhaustible fog. The fog hides the ink fragrance of the book of life and death, and also hides the obsessions of countless souls. And Shangguan Yu is the most special existence in this netherworld - she is not a ghost who seduces people and demands their lives, nor is she a judge who decides cases and sentences, but is just a little scribe in charge of the wordless book of life and death.
Three hundred years ago, Shangguan Yu was a female historian in the human world. She was wronged and died after being given poisoned wine because she wrote down the evidence of the emperor's crimes. When her soul entered the underworld, she refused to drink Meng Po Soup. She would rather give up reincarnation in exchange for a pair of eyes that could see through the soul's past and a pen that could rewrite obsessions. King Yama admired her pride, so he handed her the wordless book of life and death, and ordered her to record those souls that were omitted from the book of life and death and lingered with obsessions.
During the day, she stayed at the end of Huangquan Road, watching the flowers on the other side blooming in full swing, and listening to Po Meng's sighs from the Naihe Bridge; when night fell, she held a green lantern and walked in the gap between the yin and yang worlds, to avenge the wronged, untie the bounds of the obsessed, and seek justice for the dead. She has seen the female ghost who has been waiting for her lover for eight hundred years in Wangchuan. She has seen the general who died in battle but his name was not even recorded. She has seen the scholar who was framed by his loved ones and whose soul did not dare to enter reincarnation.
