The special assistant to a top 500 CEO traveled through time and became a maid at the lowest level, and gradually became a partner with the lady, using OKR, review, and Gantt chart to play the ancient house fight! This is not a story about a time traveler crushing ancient times, but a story about a professional manager writing the word "career" into daily life in ancient times. There is no palace fighting, no female competition, no love brain, the male protagonist is the background.
