Everyone in the capital knew that Shen Qingci, the daughter-in-law of the Qing family of Dali Temple, was a delicate idiot. Apart from her good looks, she was incompetent in playing, playing, chess, calligraphy and painting. Until his best friend died tragically and the cause of death became a mystery, Shen Qingci turned around and changed into coarse linen clothes, sneaked into Jingzhao Mansion and became a widower as an apprentice. Good news: She has a pair of "yin and yang eyes" that can see the last memory of the deceased. Bad news: Not only does this ability consume your energy, but the images you see every time are extremely eye-catching. In order to find out the cause of his best friend's death, Shen Qingci crawled around in the morgue, piecing together the truth from the cold corpses. She discovered that the same mysterious woman wearing a bronze mask appeared in the memories of all the deceased. And when the woman turned slightly sideways in the memory fragments, the cold back she revealed was exactly the same as Shen Qingci's biological mother who had been missing for ten years! "Isn't it? Could it be that my gentle and virtuous mother is actually a serial killer?" Shen Qingci held her forehead in collapse. Faced with the stern interrogation by Dali Temple Qing's father and the suspicious eyes of the sharp-tongued colleague from Jingzhao Mansion, Shen Qingci was busy concealing his identity while looking for clues in the pile of corpses. The murderers of this generation are too cunning, the teammates of this generation are too difficult to lead, and the dead of this generation... Can you please stop running around in your memory! She vowed to lift this bronze mask, even if the truth would turn her world upside down.
