A stroke of paper, a piece of paper, writes the gatherings and separations of the three realms; one life, one lifetime, sees all the joys and sorrows of all living beings. Jun Chi was a book demon who wanted to write a powerful "Interviews with Ancient Demon Gods", so she bid farewell to her friend Jiaolong and left her hometown. Along the way, she met Hydra, Taotie, Xingtian, Minshan, Wangwhale and other legendary demon gods with unique personalities, and recorded their warm or sad stories of friendship, love and family affection. However, her creative journey was not smooth sailing, and she began to question the meaning of writing a book. Fortunately, Bai Ze appeared in time to lead her out of the haze, and also brought her a sweet love. After seeing the mountains and rivers of the three realms and experiencing all kinds of demons and gods, she found that the scenery was better in the human world.
