This can be regarded as a vulgar time travel article. The person who traveled through time was not a young lady, not a lady, not an ordinary girl, and not even a princess. This novel tells the story of a maid who has no father or mother. Next to each protagonist there are one or two maids, some are smart or well-behaved, some are ruthless, some are destroyed by ruthless hands, and some have been buried in the land of unknown location. When the maid becomes the protagonist, how will the world be turned upside down? This is not a story about a vulgar mistress getting promoted, nor is it a story about Du Lala's promotion. It is just a look at the fighting in the deep house compound from the perspective of a maid.
