Cached novels are usually stored in the browser's buffer. If the browser does a clean operation, the buffer file will be deleted. Therefore, in order to preserve the content of the novel, the following measures can be taken: 1 Use a different browser or browser extension to access the novel to ensure that the content is not affected. 2. Use the browser cleaning tool to clean up the files regularly to ensure that the files in the buffer won't accumulate too much. 3. Save the file in a secure storage device such as cloud storage or a local hard drive to prevent accidental deleting or damage. 4. If the novel website supports online updates, please ensure that you update your browser's buffer regularly to ensure that the content is updated to the latest version. By taking these measures, you can ensure that the content of the novel that you have already downloaded will not be affected and can be accessed when needed.
