Lin Miyue, a recent graduate of the Magic Academy, joins the Special Affairs Department of the Weilan Magic Company and becomes partners with Pei Yan. Files that work on their own, cargo disappearing into thin air, and magic quill pens writing on their own. Eccentric commissions roll in one after another. The two need to rush to different scenes to track down the source of the magical anomalies, uncover the true cause through layers of clues, and solve cases one by one.
