I recommend "First-class Servant" to you. This novel tells the story of the protagonist fighting against evil slaves and entering the good books. There is a universe in the sleeves of the little servant. His father was taking the imperial examination outside, and he was tricked by his father into becoming a servant. Under his persistent efforts, he had gone from being a nobody at the bottom to the peak of power. I hope you like this fairy's recommendation. Muah ~😗
