Lin Jinxiu, the best embroiderer in the south of the Yangtze River, can embroider breathing flowers and birds, as well as affectionate eyebrows, but she doesn't know that she carries the secret of the royal family of the previous dynasty. A dilapidated palace-banned embroidery called "A Hundred Birds Paying Attention to the Phoenix" drew her into a shocking whirlpool. The seventh prince, Lu Jingheng, came to investigate the case, but was impressed by her concentration on the subject. From the misty rain in the south of the Yangtze River to the high walls of the deep palace, she used the embroidery needle as her sword and her embroidery skills as her armor to carve out a beautiful path amidst conspiracy and murderous intent.
