How Can I Serve Someone with My Looks?

10/8 Announcement: I'm a little stuck today, so the next update will be tomorrow. So sorry! Completed story: "State Preceptor, Shut Your Mouth!" A huge secret resides within Bai Su's three-foot-tall body: after going berserk during a vicious fight, she reverted to the body of a six-year-old girl, becoming the most aloof and powerful little brat in the world, until she was kidnapped and sold in Xuchang to serve as the foot-washing maid of Grand Commandant Han Gong. Bai Su: I am a grandmaster of my generation. How could I debase myself by using my looks to serve someone? Madam Wang: You little brat, you haven't even grown your body hair, and you're already talking nonsense. That's our Grand Commandant! What's wrong with bringing him a basin of foot-washing water? Han Gong's lips curled slightly as he bent down to look at her, as if he could see the eighteen-year-old woman she would become: Tsk, what a little beauty. Reader's Guide: 1.
