Wow! I Won the Fourth Master's Harem with My Beauty

[Qing dynasty setting + alternate history + Fourth Master + special powers + palace and household intrigue + raising children + strong female and male leads later on] She transmigrated to the Qing dynasty and stole the transmigrator’s golden finger??? So she’d come to the Qing dynasty because of another transmigrator. Well, she wouldn’t hold back. That woman had wanted her dead, so taking her System couldn’t be wrong. But why had Fourth Master come running over? Song Shu: Nooooo! The rewards came first, and the System arrived later. Let’s see how she can win Fourth Master over, have his babies, and become his favorite consort! The male and female leads are relatively innocent at first and need time to grow. This is a story of childhood sweethearts who stay together from their first love until old age. Newly on the job, Song Shu finds herself facing the famous scene where Consort De chooses palace maids for Fourth Master. Luckily, she’s just a little maid standing off to the side, not one of the women involved. Once she’s old enough, she can leave the palace, marry her childhood sweetheart, and live a quiet life. Just as she’s congratulating herself, Fourth Master grabs her. Song Shu cries out in terror, “Fourth Master, you’ve got the wrong person!” By accident, she binds herself to the transmigrator’s System and receives beauty-enhancing rewards that make her prettier by the day. But it seems she isn’t the historical Consort Mao? Isn’t the woman beside her the one?
