Rebirth of Jade

It's not good-looking. It's said that the 14-year-old heroine has very good medical skills. She can suture and set bones. She saved people who were dying. But they also emphasize that in her previous life, she was a 17-year-old freshman medical student. I'm really convinced. What can I learn in my freshman year? Even if he is a junior or senior, he should be stronger. In addition, there are many characters on the scene, trust and friendship come suddenly, and the characters' personalities and backgrounds do not match. The author cannot control the relationships between so many characters, and the plot seems a bit confusing and rambling.
