Lin Wan, a modern medical girl, accidentally traveled through the harem of the Qing Dynasty and became the palace maid Wan'er. With her superb medical skills and modern knowledge, she helped the show daughter Laner stand out in the talent show, and she repeatedly saved the day in harem battles. Wan'er won people's hearts with her medical skills, helped Lan'er to be promoted to concubine, and gave birth to a prince. Faced with the palace intrigues and the struggle for the throne, Wan'er and Lan'er sisters worked together to plan the Xinyou coup, which ultimately helped Lan'er ascend to the pinnacle of power and become the Empress Dowager Cixi, ushering in the era of listening to politics behind the curtain. Wan'er also retired with great achievements, hanging the pot to help the world, and her medical heart is eternal.
