Su Qing

In the 10th year of Xiantong in the Tang Dynasty (869 AD), Chang'an, under the surface prosperity, was full of strife among powerful people, secrets in the harem, and undercurrents in the world. The imperial court newly established the "Internal Procuratorate", which nominally collates palace classics, but is actually a women's investigation agency secretly established by the queen. It is presided over by Shen Qinghao, a female officer of the Shangyi Bureau, and specializes in investigating secret cases involving the harem, married women, and the inner houses of powerful people. Six years ago, Shen Qinghao's twin sister Shen Suhao - the late emperor's favorite talent - was accused of using witchcraft to curse the queen and died in the cold palace. The Shen family was wiped out, but Shen Qinghao was spared because she was raised in a Taoist temple since childhood. On the surface, Shen Qinghao surrenders to the queen, but in fact, she is secretly investigating the truth about her sister's unjust case. All clues point to a jade pendant engraved with "faceless Buddha". This jade pendant involves several old cases in the palace, a shocking secret involving the emperor's bloodline, and a secret force "Wuxiangzhai" that has been entrenched in Chang'an for many years.
