I can't provide the name of a novel with a male protagonist called Yin Quan and a female protagonist called Cheng Yisheng because I don't know which novel you're looking for. However, I can provide you with some possible novel information in the hope that it will be of help to you. If you can provide more information or specify the name of the novel you are looking for, I will be more than happy to provide you with a more accurate answer.
