The heroine Shen Ningyan was originally from a famous family, but after her family was wronged, she became the lowest embroiderer in the palace. Unwilling to sink, she used her superb embroidery skills to attract the attention of the imperial concubine and got involved in the cruel battle for the right to inherit the throne. In the absence of a system and space, she relied on her ultimate insight into human nature and meticulous layout, starting from an embroidery workshop, passing through palace maids, talented people, and virtuous concubines, and finally killed powerful officials in the turbulent political struggle, supported the new emperor (male protagonist) to ascend to power, and worked side by side with him. The highlight is the heroine's "sober in the world" character. She is not like the Virgin, and every move must be bloody. She uses embroidery code words, silk thread poison tricks and other ancient handicraft elements to engage in high IQ games.
