In a multi-chapter অনুরাগী fiction, there ought to be a box in the শীর্ষ right corner which says "1. Chapter 1" অথবা whatever the first chapter's শিরোনাম is if it's been titled. আপনি simply need to click on that box, open the drop down তালিকা and select the পরবর্তি chapter. অথবা আপনি can click the পরবর্তি button which is to the right of the drop down box.
If you're talking about fanfiction as প্রবন্ধ on Fanpop, not fanfiction.net, the simple answer is that আপনি can't. There's no way to connect different chapters. আপনি just have to look at the প্রবন্ধ in the club, অথবা in the member's activity feed, and open up the পরবর্তি chapter article. That's why Fanpop's fanfiction প্রবন্ধ work best for oneshots and not multi-chapter stories.
