Since the birth of the primordial witch in ancient times, women with special powers have continuously emerged in this world. These women with special powers are called "witches." The power of witches is unpredictable and will not disappear; after a witch dies, they will leave behind "witch relics" with special powers. Zhang Xiaoyang, who just wants to live a peaceful life, one day picks up a witch relic called "Future Notebook." This becomes the catalyst for him to come into contact with another side of the world and begin his own strange adventure.
