readlightnovels.net is a free webnovel sharing website. This tool allows you to scrape the aforementioned website for lightnovels and save them in pdf format on your device.
NOTE : If someone is actually using this project, give this repo a star or contact me on reddit. I'll update the docs and make the program more user friendly then. For now I made the program for my own use, if you need it as well, please do the aforementioned. Cheers!
