The Maid Holds the Universe in Her Palm

Modern office drone Shen Qingqing opens her eyes to find herself in the fictional Great Sheng dynasty, as a lowly menial maid in a powerful clan's household. From the start, she's pinned to the flagstones and sentenced to death by beating. She has no intention of currying favor with anyone, and she refuses to believe in fate. Armed with the Civilization Engineering System, she plans to use ledgers, institutions, and engineering know-how to start by cleaning out the parasites in one household, then wrest power from the great clans and change the dynasty.
