I am honored to be able to recommend a novel for you. According to the information you provided, the novel I recommend is "You Belong to Me". This is an ancient romance novel. The protagonist of the story was a female general of the Empire who had no feelings for half her life. Because her spiritual power was injured and needed treatment, she traveled to a different world. In each world, she had different identities and experiences, and she had different love stories with various male leads. With the help of the system and the small world, she had regained the process of finding herself. I hope you like this fairy's recommendation. Muah ~π
