On a smartphone, the novels that were sent would usually be saved in the inbox or sent folder. This folder would usually be displayed in the application on the phone and could be found through the search or browsing function in the application. If the novel you send contains a specific format or file type, it may be saved in a specific folder. For example, if you send an e-book, it may be saved in the e-book folder. However, the specific storage location may vary depending on the phone brand, model, and operating system.
