Caching the entire novel meant that the entire copyright of the novel was stored in the cloud so that readers could download and read it for free on any device. Currently, there was no application that could achieve the function of storing the entire novel because of the limitations of copyright protection regulations. The copyright of a novel was usually divided into multiple parts, and each part had a different copyright owner. However, some streaming platforms and online reading platforms have already introduced a portion of the buffer function, allowing users to buffer specific chapters or passages and then continue reading on other devices. However, these features do not apply to all novels because these features require the platform to negotiate with the copyright owner and obtain authorization. Therefore, if you want to use the entire novel as a buffer, you should try to use some third-party novel search engines such as Baidu Library, Google Files, etc. These search engines can search and download the full text of the novel, but you need to pay attention to copyright protection regulations.
