Traveling Through the Wude Era and Relying on Medical Skills to Change the History of the Tang Dynasty

I'm a newbie, I just wrote, my writing is not good, I hope you can forgive me. Lin Heji, a doctor of modern medicine, accidentally got into a car accident and traveled through time to become a sick five-year-old girl in a small village during the Takeru era. She was accepted as an apprentice by Sun Simiao. While she was studying medicine and traveling diligently with Sun Simiao, she was secretly paying attention to the external situation. After the Xuanwu Gate Incident settled and Li Shimin ascended the throne, Lin Heji took the medical knowledge from his previous life and the desire to save people, and officially set foot in Chang'an to treat various key historical figures. Therefore, he changed the path of the history of the Tang Dynasty and also changed the medical treatment of the Tang Dynasty with his own influence.
