Qingci, the concubine of the Shen family, used an embroidery needle as a blade to cut a bloody path in the mist of the deep house. The biological mother drowned mysteriously, stolen goods were hidden in the accounting room, and the coarse linen in the warehouse was wrapped with tribute sandalwood - all clues pointed to the powerful Li family.
She used the "flying silk embroidery" technique to hide secret messages, and the "coagulated blood embroidery" to store evidence of guilt, and laid a dragnet between square inches of silk. When the Big Dipper chart guides the truth, and when half a jade pendant piece together the past, it becomes clear that the death of the biological mother was actually the tip of the iceberg of a palace conspiracy.
From the warehouse of the Shen Mansion to the embroidery rack of the Shangfu Bureau, from the escort office in the market to the high walls of the palace, Qing Ci holds the needle like a sword, embroidering the conspiracy into ironclad evidence and making the crime visible to the sky. In the end, the blood-stained embroidery needle not only cleared the wronged soul, but also helped her transform from an embroidery girl in a deep house to a behind-the-scenes chess player who stirred up the storm. She took charge of her own Phoenix Seal legend among the embroidery.
