Zhou Yuan, a doctoral student in the Department of Modern History, traveled to the Qin border in the late Warring States period during an archaeological accident. He was discovered by a Qin army patrol and escorted to Xianyang. Zhou Yuan attracted the attention of Prime Minister Li Si by virtue of his understanding of history, and got the opportunity to meet the King of Qin Ying Zheng who had not yet taken charge of the government. He shocked the young king by showing his knowledge of the future with the "Book of Heaven Prophecies". Zhou Yuan proved his worth by solving Qin's food crisis, improving farming technology, predicting locust plagues and other events. He was appointed as a guest minister by Ying Zheng and gradually gained trust. Zhou Yuan navigated the complex political environment of the Qin court and established a relationship with Li Si as both enemies and friends, while at the same time he was wary of the forces of Lu Buwei and Lao Ai. As time went by, Zhou Yuan faced the moral dilemma of whether to change the historical line of Qin Shihuang's tyranny, and began to think about how to embed more benevolent governance concepts in the unification process.
