I, Ouyang Mengmeng, a beautiful new human girl of the 21st century, the beauty of the talented student of "Redmond High School", actually on my 18th birthday, due to a small accident, I traveled to an unrecorded dynasty in history, "Qinyuan Dynasty", and transformed into a little baby, Lan Mengmeng, who was just born to the prime minister of the dynasty. Oh my gosh! I don't want to become a baby again! But since you're here, you have to have some fun, right?
