Su Xiaoman, a street vendor girl, bought a piece of "bad luck jade" from the ghost market in order to raise tuition, and accidentally awakened the ghost king Gu Yi who had been sleeping for a hundred years. The two are forced to bind: she needs to collect wishes for him to repair her soul body, and he needs to help her avoid supernatural disasters. Su Xiaoman sells goods during the day and catches ghosts at night, while Gu Yi makes venomous remarks but secretly defends his shortcomings. From "helping the square-dancing aunt find her missing wife" to "breaking the curse case of a wealthy family", the mystery of Gu Yi's life experience is revealed in a lot of jokes - he is actually the head of the Soul Suppression Division who voluntarily sealed a hundred years ago to suppress evil spirits, and the best friend who betrayed him back then is lurking in the modern city, trying to open the door of ghosts. Su Xiaoman used a mortal body to practice wild magic spells such as "pendulum asking for directions" and "street stall enchantment", and fell in love with Gu Yi while fighting each other. In the end, with the wonderful combination of market wisdom + ghost world magic, he solved the conspiracy a hundred years ago and allowed Gu Yi to truly be freed.
