Lan Xin has been guarding the Wangyou Inn for an unknown amount of time. This inn hangs between the three realms, and all the guests who come and go are gods, demons and monsters. With a cup of "forgetting drink" as a guide, she listened to their obsessions, resolved their knots, and helped them find their way back. But every time she saw off a guest, she would always rub a patternless silver bracelet on her wrist and ask herself in a daze: Who am I? Why here? Where is my return?
