Su Yao, a modern Qin Dynasty history enthusiast, was accidentally shocked by an electric shock and traveled back to the end of the Warring States Period with her mobile phone. When she woke up in the wilderness, she found herself on the border of Qin and Zhao, and her mobile phone became her only modern certificate. After encountering Qin Shihuang Yingzheng by chance, she relied on her knowledge of military tactics and historical insights on her mobile phone to help the Qin army avoid ambushes and seize the city. She also proposed reform strategies such as easing corvee and training new troops, which made Qin's national power grow stronger. In the process of assisting Ying Zheng in unifying the six countries, the two went from getting to know each other as monarchs and ministers to developing a secret love, and worked together to resolve the dissension and internal political resistance of the six countries. In the end, Ying Zheng made her the queen despite all the opposition, but Su Yao used her wisdom to rewrite history and became a mysterious and legendary queen in the history of the Qin Dynasty, opening a new chapter of prosperity for the Qin Dynasty.
