I recommend the book "Hidden Doctor" to you. The story is very similar to the description of the question. The female protagonist, Qin Nianxi, had transmigrated to the world of the female god. At first, she was unable to speak due to her injuries, but her medical skills saved her. After that, she relied on her amazing medical skills as a backing and relied on her own strength to step by step towards success. I hope you like this fairy's recommendation. Muah ~😗
