Lin Wei, a reborn history lecturer, just wanted to stay away from her ex-husband, an academic leader who plagiarized her achievements, but she was forced to bind herself to a system that broadcast the future to Qin Shihuang. Facing the emperor of the ages, she tremblingly revealed the death of the Second Emperor of Qin Dynasty, and casually added, "For example, Young Master Hu Hai is not very good." Immediately, news came from Xianyang that the Eighteenth Young Master had broken his leg. Her "directional crow's mouth" became the most terrifying advice--complaining about Zhao Gao, Zhao Gao was jailed; commenting on the law, and revising the law. Under her "warning", the Great Qin Dynasty went all the way, and her ex-husband, who once treated her like a worn-out shoe, discovered the crazy changes in the history of Qin through archaeology, and his worldview completely collapsed, and he began a humble and fanatical pursuit that spanned time and space. When the First Emperor asked her the ultimate question in the live broadcast, and her ex-husband protected her with his lifelong scholarship, Lin Wei held the "crow's mouth" and stood at the center of the whirlpool that changed history: This time, she wanted to advise a new path for herself and for Chinese civilization.
