In the second year of Guangxu's reign, Huangya Mountain suffered from a severe drought for three months. In order to seize the cultivated land in Yingchoujian and embezzle relief grains, he colluded with Kong Yanchang, his uncle in the Confucius family, and led his officers and soldiers to massacre the village. He also poisoned the grain, grass and water wells in an attempt to wipe out the entire village.
Four women, Su Xiu Niang, the embroiderer's daughter, Hong Fu, the escort's daughter, Kong Lingyi, the rebellious daughter of the Confucius family, and Qin Huaisu, the medical woman, formed a team to resist in times of danger. Su Xiu Niang recorded the evidence of crime with code embroidery, Hong Fu broke out of the siege with a bloody iron sword, Kong Ling Yi exposed the family conspiracy, and Qin Huai Su prepared medicine to detoxify and defeat the enemy.
They not only have to fight against the pursuit of officers and soldiers and the shadow guards of the Kong Mansion, but also need to uncover the traitors lurking around them. They also need to break into the official warehouse to seize the stone marrow and explore the Kong Mansion to obtain evidence of guilt. From breaking out of the siege at Huangya Mountain to breaking into the palace in the capital, the four used needles, knives, medicine, and wisdom as their blades to expose the corruption and thwart the feudal king's rebellion. In the end, the corrupt officials were brought to justice, the people lived in peace, and they used blood and courage to embroider a clean world.
