You can try to down it esp if youre using android and google. If u go to the three dots setting there should be a download page option there. Pr you chan use safari, share icon on lower right, change option to pdf or webpage, then save to files.
But you have to do it individually each chapter but the download in google is fast. I tried it when i was reading solo leveling and had download half the chapters cos we lost wifi and i had to ise data. Also when u download from google make sure the page loaded completely cos if u download when the panels are still loading it will download as is.
Thank you!
Does someone know where I can download the pages? I really want to read it while traveling ;-;
