Su Jinning entered the palace as a maid with a golden finger that was "specialized in medicine and poison." When she first entered Yeting, she was poisoned by Concubine Lin and made things difficult for her by Zhao Yuyao. She used her golden fingers to identify the poisonous scheme, used homemade antidote to fight against the troublemakers, and accidentally saved the Queen Mother who was poisoned, and was secretly protected by the Queen Mother. Xiao Che saw that she had saved danger many times, and gradually became interested in her, so he promoted her in an unusual way. Faced with Concubine Lin's frame-up and Zhao Yuyao's imitation, Su Jinning used the art of medicine and poison to set up a trap to make the enemy suffer the consequences. The two gradually fell in love during the palace fight. In the end, Su Jinning ascended to the post, and worked with Xiao Che to investigate the unjust case of the Su family, clear up the chaos in the harem and the court, and use medical skills to protect the peace of the harem.
