A drop of dew merged into the body of a woman (Chaolu) to replace the original owner, and she entered the harem of Dasheng Dynasty with stunning dancing skills, because the ten thousand-year-old elves can understand people's hearts and sense emotions. Therefore, the truth about the previous emperor's harem conspiracy to seize the throne was discovered. Sheng Yuanpei wanted to take revenge on the Queen Mother because of her mother-in-law's hatred, so that she could taste the pain of losing her treasure. The Yan Ji family also secretly contacted Queen Yan Xue to use the false pregnancy to seize the throne. On the one hand, Chao Lu faced the conspiracy and frame-up in the harem, the Queen Mother's obstruction and taboo on his investigation of the past, and the Queen's jealousy on his sympathy with the emperor. On the other hand, Chao Lu was always looking for opportunities to untie Sheng Yuanpei's hatred. And because his original love for Yan Ji was too strong, Chao Lu was in danger many times, and even lost his soul. It wasn't until he discovered that his feelings for Sheng Yuanpei were deep enough that he could suppress the original owner, that he was truly able to control it. And with the relationship between Chao Lu and Sheng Yuanpei, Chao Lu completely integrated into this era and this body. From an unconscious dew, she tasted the taste of love, family affection, and friendship, and finally gave up her spiritual power, saw the changes in world affairs and people's lives, and gained her own cognition and emotions.
