The modern girl Luo Qingchuan is a history student who is particularly obsessed with the history of the Qing Dynasty, especially the story of "Nine Sons Seizing the Rightful Son". By chance, she accidentally traveled back to the Kangxi period of the Qing Dynasty after touching the Kangxi Jade Seal in an antique shop, and became a palace maid next to Prince Yinreng. Living in a strange ancient palace, Luo Qingchuan relied on modern knowledge and optimistic character to deal with the crisis-ridden harem and the struggle with the prince. She first met the gentle eighth elder brother Yinzhen, and the two gradually developed feelings for each other from testing each other. Later, she met the fourth elder brother Yinzhen, who was deep and tolerant and had clear goals, and fell into complex emotional entanglements.
