I recommend 'I'm a Big Boss in the Book of Transformation'. This was an ancient romance novel. It told the story of a modern girl, Liu Huahua, who followed the newbie system Xiaobai to travel to different worlds, such as ancient times, modern times, fantasy, Xianxia, Wuxia, apocalypse, matriarchal society, and so on. Their identities were also different. The mission was to use all means to capture the heart of the true male protagonist, and all kinds of sweet and refreshing rewards. I hope you like this fairy's recommendation. Muah ~đŸ˜—
