In the Su family in Bianjing in the Northern Song Dynasty, the concubine Su Jinse was an "outsider" who was not even qualified to enter the ancestral hall. Her aunt, Zhou, regarded her as a thorn in her side. Her eldest sister, Su Linglong, took her credit and framed her to death. Even her father had doubts about her because of her "concubine's involvement in politics".
There was a fire in Nanchang overnight, and she was accused of "negligence in defense" and was almost imprisoned in Jingyun Court for life; she finally relied on salt to establish a case, and the Queen's birthday tribute silk showed "poison cloth", and the entire Su family was at risk of being implicated; Wei Zhao of Hengyuan even blocked the city's silver roads, threatening to swallow up the Liaodong trade route she had finally opened up, turning her from a "hero of the Su family" back into a concubine at the mercy of others.
Everyone was waiting to see her downfall, but this flower that grew in the mud was determined to overturn the chess game with every stitch: In the fire scene, she peeled away the ashes to identify the traces of tung oil, and found out the ironclad evidence of arson in the second room; in front of the Suzaku Stage, she boiled cloth to test for poison, and used "three types of truth identification" to break the "poison cloth" rumor. Even the emperor gave her "commendations for diligence and caution." When the silver route was cut off, she enlisted hundreds of noble ladies to sign a crowdfunding campaign, which broke Wei Zhao's capital chain. Even the plan of "marrying a sick young man" calculated by her aunt, became a springboard for her to enter the Yan family and control water transportation - no one expected that the sick eldest son of the Yan family would actually be her ally in conspiracy to plot overseas trade routes.
But no one knows that in the red gold phoenix crown left by her mother Liu, in addition to the secret method of weaving and dyeing, there are also clues to the old cases of the previous dynasty - it is her mother's last wish that she must fulfill, and it is also the ultimate secret that can shock half of the court...
