Shen Lanxi entered the palace as a maid with a "poisonous heart and wise eyes". When she first entered Yeting, she was poisoned by the queen and made things difficult for her by Concubine Li. She uses her golden fingers to detect poisonous schemes, uses poisonous techniques to counteract the palace maid who wants to harm her, and gains trust by detoxifying the favored virtuous concubine. The regent Xiao Jue gradually became interested after seeing her repeatedly saving danger. Faced with the Queen's frame-up and Su Qingyao's imitation, Shen Lanxi used poison to make the enemy suffer the consequences. The two gradually fell in love during the battle in the palace. In the end, Shen Lanxi ascended to the throne and worked with Xiao Jue to investigate the Shen family's injustice, clear up the chaos in the harem and the court, and use poisonous techniques to protect the peace of both parties.
