The cold palace embroiderer used embroidery as a tactic, weaved evidence of corruption into her embroidery, and counterattacked step by step, rising up in the palace intrigues. In the desperate situation of the cold palace, Xiao Jinse, the former princess of Anle and the daughter of the God of Embroidery, bears the blood feud for her mother's tragic death. She uses an ebony embroidery needle as a blade and silk thread as a net to make her way step by step in the desperate situation of the deep palace. She took the opportunity to celebrate Princess Shen's birthday and used her unique double-sided embroidery to hide the evidence of corruption in the embroidery, overthrowing the evil slaves who oppressed her and taking the first step of revenge. Later, relying on her peerless embroidery skills, she gradually rose from being an abandoned girl in the cold palace to becoming a palace official. She uncovered layers of conspiracies such as her mother's tragic death, the shroud in black satin, the cold poison controlling the emperor, and the secret of the murder. It was discovered that her mother's death involved the queen's usurpation of power, the corruption of the previous dynasty, and the collusion of Beidi. She used embroidery as a plot, used needles to break the situation, and borrowed the power of the proton Murong Yuan to set up a dragnet between the turbulent harem and the court, and liquidate the enemies who participated in the conspiracy one by one. From embroidering handkerchiefs to hiding secrets, blood embroidery to convey messages, burning embroidery to prove innocence, and gold thread to reveal guilt, Xiao Jinse used the delicate body of a woman and her peerless embroidery skills to protect her mother within the man-eating palace wall, stir up the court situation, and finally used her embroidery power to determine the outcome and complete a desperate counterattack.
