As a fan of web novels, I don't have the resources to read the novel " The Fourth Prince and the Fourth Princess." However, I can recommend you some related novel websites or platforms such as Qidian Chinese Network, Xiaoxiang Academy, and tencent reading. You can try to search for the name of the novel on these websites to see if there are resources to read. In addition, if you are interested in a particular novel, you can also use some online reading platforms such as Netease Cloud Reading and the Kindle to read the novel's resources. I hope these suggestions will be helpful to you!
