After working overtime at night, a cup of coffee spilled on the keyboard, and Lin Yufei, a modern social beast, directly traveled to the lowest level of the harem and swept the palace maid! As soon as he got used to the coarse linen clothes, he bumped into the emperor who looked exactly like his boss who "exploited his employees". He was so shocked that he dropped the broom in his hand. In order to find an explanation for her "boss", she started a palace survival copy: she used garbage classification to fix the utility room, used the formula of laundry detergent to impress the laundry department, used a mind map to impress the emperor, and even dared to call the emperor "Mr. Zhang" in private and was caught on the spot. From palace maid to queen, she used modern memes to play around in the palace, but she also experienced breakup and heartache due to the gap in status. When Emperor "Mr. Zhang" embarks on a long journey to pursue his wife, how many funny and heart-warming sparks can be created in this time-traveling "superior and superior workplace" love affair?
