Shen Qingwu, the female shopkeeper of the embroidery shop in the Dajing Dynasty, was actually the daughter of the imperial physician of the previous dynasty. She was exterminated because her family was involved in a witchcraft case. She relied on her ancestral "medicine embroidery" skills (embroidery dyed with poisonous weeds to embroider at a moment's notice) and hid in the market. When King Jing Xiao Che was ordered to investigate the remnants of the previous dynasty, he was attracted by the totems of the previous dynasty hidden in Shen Qingwu's embroidery. The two gradually fell in love through mutual tentative cooperation (Xiao Che needed her to identify poisonous embroidery on old palace objects, and Shen Qingwu needed to use his power to find the real culprit). However, they discovered that the mastermind of the massacre was actually Xiao Che's mentor - the current imperial tutor.
Concept: Shen Qingwu used his seemingly weak embroidery skills to resolve crises many times during the investigation process, such as using poisonous embroidery to fight back his pursuers; Xiao Che went from suspicion to trust to joining forces, the powerful collision of power and skills; the reversal moment that revealed the true face of the Taifu.
