Was the female protagonist of Cang Luo's novel the male protagonist's adopted daughter?

I strongly recommend the novel,"The Palace Robbery of the City-Toppling Empress" to you! The female protagonist, Cang Luo, had gone from being the daughter of the prime minister's manor to the lowest palace maid of the laundry department in the palace, and finally became the empress. She was deeply involved in the internal strife of the palace. The plot was compact and the characters were well-rounded. The relationship between the female lead and the male lead was also moving. I hope you like this fairy's recommendation. Muah ~😗
