(*Completed, so enjoy! My new novel, Has the Crown Prince Been Pressured to Marry Today? [Qing Transmigration], is now underway. If you're interested, come check it out!*) Blurb: Lan Qingyi transmigrates to the Qing Dynasty and is fortunate enough to become the least important person in Fourth Prince's household: a concubine-in-waiting. She looks at the principal consort, who has borne a legitimate son and controls the household, at Side Consort Li, who has two sons and a daughter and remains beloved, and at the future Empress Dowager and the future Noble Consort Yu, and decides it's best to stay away from trouble and focus on staying alive. Luckily, she has an Embroidery System that can automatically embroider any design she draws, reproducing it with 100% accuracy. Lan Qingyi: I can embroider Buddha statues, phoenix robes, and portraits, too! A Thousand Li of Rivers and Mountains... Um, that one might take a while. Just give me a private space and we can work something out! Reborn, Fourth Prince has a secret. He has a Quest System. Whenever someone embroiders a design he draws, he gains closeness with his family based on how well the embroidery is done. And the person whose embroidery is the best is the little concubine he ignored in his previous life. Fourth Prince decides that in this life, he will treasure Lady Lan, the key to the treasure chest Heaven gave him! Content warnings: 1.
