In the 33rd year of Yonghui's reign in the Great Zhou Dynasty, a bloody eye suddenly appeared in the "Longevity Splendid Picture" of the Lantern Festival, and three hundred embroiderers were beheaded. In exchange for this, the minister ordered Shen Huaijin to obtain a list of rebels in Northern Xinjiang, and was granted the title of marquis and prime minister. However, the real embroiderer, his sister Shen Xiu, became an unknown stand-in on the guillotine. She was secretly rescued by the eunuch Feng Xuanji and imprisoned in the embroidery bureau. She was given one year to embroider a "map of mountains and rivers" and exchanged military intelligence for her brother's head. Shen Xiu appears to be obedient, but secretly creates the "Imperial City Fire Veins Diagram" with royal medicine, gold steel thread, and black silk, intending to burn the emperor's capital and bury him with him. On the night of the winter solstice, the picture was completed, but the truth turned again: Shen Huaijin had known that his sister was not dead, and deliberately used her hands to embroider the picture to lure Feng Xuanji and his party to appear, and then sacrifice his sister a second time to avoid future troubles. Shen Xiu used his brother's white hair as a cue to ignite the "reverse fire", turning Shen's house into ashes overnight, leaving charred bones. The emperor sealed the bureau to arrest the murderer, and Shen Xiu escaped into the wind and snow, becoming the leader of the "Jinshi Diao". He used brocade thread as a blade to stab the powerful. Every time he killed a person, a corner of the brocade was left, and a phoenix eye was missing. The empty space was just enough to fit into a human heart. Since then, the world has known that an embroidery needle can weave auspicious clouds and turn mountains and rivers upside down; the most poisonous thing is not the plot, but that after being pushed into the abyss by your loved ones, you can still strangle the throat of the entire era with a ray of brocade.
