Traveling Through the Qin Dynasty and Becoming the Agent of the First Emperor

Female protagonist: Lin Xiaoxiao, a 25-year-old modern social worker, history graduate and talk show screenwriter, was reborn as "Zhao Xiaoxiao", a girl on the border of the Zhao Kingdom at the end of the Warring States Period. She was accidentally involved in the succession crisis of the Qin Kingdom, and became the most unreliable but most effective "modern military advisor" around the young Ying Zheng (named Zhao Zheng at this time).
