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

Answer edited because I realised the pergunta could be asking about fanfiction on Fanpop.
