Lin Yue, a modern history researcher, accidentally triggered a mysterious mechanism while studying cultural relics from the Qin Dynasty, and traveled through time to become the princess of Chu who was about to become Queen Yingzheng. At this time, the undercurrents of the Qin Kingdom were surging, Lu Buwei was in power, the Empress Dowager Zhao and Lao Ai were in chaos in the palace, and the six countries were watching with eager eyes.
Lin Yue is well aware of the trend of history. With the help of modern knowledge, he first cleverly designed to help Ying Zheng uncover Lao Ai's party, suppress Lu Buwei's power, and stabilize the king's power. In the harem, she relied on her high emotional intelligence and wisdom to control all forces, making it impossible for concubines with evil intentions to take action.
Externally, Lin Yue improved weapons and taught new military training methods, helping the Qin army to sweep across the six countries; internally, she promoted advanced farming technology and built water conservancy, which greatly increased Qin's national power. She also proposed to Ying Zheng the unification of characters, weights and measures, laying the foundation for the unification of the country.
As they get to know each other more and more, Ying Zheng's initial use and appreciation of Lin Yue turns into a full-hearted admiration. In the process, Lin Yue also fell in love with this talented and wise emperor. In the end, Yingzheng unified the six kingdoms, and Lin Yue became the queen of Mu Yitianxia as she wished, and joined hands with him to start the prosperous age of the Qin Dynasty and rewrite history!
