In the glittering "Nishang Shopping Center", security captain Lei Zhen discovered that the image in the fitting mirror was quietly "out of shape". Customers disappeared mysteriously, and the receipts left behind showed distorted "tentacle patterns". Su Yan, a new space designer, brought with him an ancestral "space measuring instrument" and discovered that the world in the mirror was a distorted "reflection" of the shopping mall. In order to rescue the trapped people, she must set foot on a "circular mirror path" that will never look back after closing the store, wipe the key mirror surfaces, and at the same time prevent developer Wei Yanzhang from turning this strange space into a cold "endless warehouse." The "alien" in the mirror actually comes from the customer's inner anxiety and desire... This is an urban fantasy that smoothes distortions and protects the boundaries of reality between glass and light.
