I Transmigrated to the Great Qin Dynasty and Became Brother Zheng's Teacher. Years Later...

Traveling across the Qin Dynasty, I became Zheng Ge's teacher, and my daughter's identity was discovered many years later. Han Jing, a Ph. D. In the Department of History at Wudaokou, was killed in an earthquake in the library while trying to save her colleagues. When she woke up again, she traveled to Zhao State at the end of the Warring States Period and became a nameless, hungry and cold seventy-eight-year-old orphan girl. With nothing and her life hanging by a thread, she unexpectedly discovered that she could carry the entire modern library where she worked in her previous life as a "space" with her. Books, supplies, computers, and even unopened snacks, all became her only support in this troubled world. No With her familiarity with history and the vast collection of classics in the museum, she realized that this was the year 249 BC, a time when King Qin Yingzheng had not yet taken charge and the disputes among the six kingdoms were intensifying. With her admiration for "Brother Zheng" and her ambition to change history, she decided to get close to the young Ying Zheng. She presented herself as a boy, using the pseudonym "Han Jing". With her knowledge that transcended the times and the knowledge in the library, she gradually won Ying Zheng's attention and became his secret "teacher": teaching him arithmetic and geography, giving him political power, and even using chemical and physics techniques to help the Qin army improve their weapons. She helped him avoid assassination and solve the conspiracy, and also quietly promoted the budding modernization of Qin's agriculture, medicine and system. However, as Ying Zheng gradually unified the six countries and proclaimed himself emperor of the world, and expelled Lu Buwei in advance, Han Jing's daughter's identity was gradually exposed due to an accident. Ying Zheng went from doubting to relying on her, and the dependence gave rise to complicated and unspeakable emotions, and she was also caught in a dilemma in this magnificent historical process: should she continue to hide herself and help silently, or should she face her relationship with Ying Zheng calmly? Can she change the fate of Daqin?
