Imperial Sister, also referred to as Royal Sister, is Chu Ning's full-blooded elder sister from a royal family. She agrees to lend two intermediate alchemists to help Chu Ning's business expand, requesting ten percent of their pill profits as a condition. She considers this arrangement a wedding gift for Chu Ning. She is part of a royal family and has significant influence over alchemists, being able to transfer mid-level alchemists to help. Other royal siblings, including Eldest Royal Sister, Second Royal Brother, and Fourth Royal Brother, also agree to lend mid-level alchemists but at a higher twenty percent profit share.
