Ahhm this is just a suggestion but why don't you try to download the page and it will be available for offline reading. Though i believe this only work using desktop or laptops. Just go to a certain chapter you want to save and then click right click of your mouse anywhere on the page except the images of the chapter then click save as or press "control+s" and a textbox will appear where you can rename it and then you can download it. Don't leave the page unless the download is complete or else the downloaded page won't be complete. If you have questions regarding this process, you can ask me, hope this will help(▰˘◡˘▰)
