The little stone demon Yue Ke rescued the third prince of the Yuanxi Kingdom, Mu Qingchen, but he did not expect that his true form turned out to be an immortal. The Palm Star Lord and the Old Man under the Moon caught a glimpse of the secret in the Universe Mirror and asked her to protect the immortal from calamities in the mortal world. The reward is that when Mu Qingchen returns to heaven, she can ascend with honor.
In order to avoid practicing for thousands of years, Yue Ke moved forward with a heavy burden. Although her skills were shallow, she was better than her clever mind. She relied on her demon skills to look through the past lives of mortals and the scripts she had read for five hundred years. She listened to the inner walls of the house and helped Mu Qingchen solve various major cases. Of course, she would occasionally make mistakes and cause minor troubles.
In the case of the Demon Queen, Yue Ke helped Mu Qingchen protect his mother's reputation and uncovered the real culprit behind the scenes. He gradually dispelled Mu Qingchen's suspicion of her and became his most trusted maid.
During the palace battles and the silver bleaching case, Yue Ke used demonic skills to help Mu Qingchen overcome numerous obstacles and overthrow the biggest opponent in his political career. The two also developed feelings in the circle of right and wrong.
People in the capital say that Mu Qingchen dotes on the maids around him extremely, and she has become the villain that the ladies of the official family unite to fight against. Mu Qingchen is domineering, protective of his wife, and sweet, and he can be called a model of "national husband". However, beauties have different paths, and fairy monsters are even more taboo. She cannot afford Mu Qingchen's love.
In order to save their lives, Yue Ke and Mu Qingchen struggled emotionally to the limit, but due to the appearance of the witch, their power was broken, and her identity as a demon was also exposed. Fortunately, Mu Qingchen didn't care, and the relationship between the two greatly increased. However, the exposure of their identities meant that mortal cultivators were chasing them. With the help of the Master of Life and Yue Lao, the two experienced life and death catastrophes and finally ascended. But when he returns to heaven, will he still remember things in the mortal world?
