Here we have 9S simply exploring a vast memory storage area. Move along and activate each of the glowing white tile to trigger a text-based event. It's mostly just 9S talking to himself and and snippets of the the not so pleasant conversations he'd had with Adam before 2B arrived at the Copied City.
I've seen several different assumptions of what that one censored word might be and they could all be right. In any case this will be a quick chapter and should end not long after 9S hears bits of Adam's monologue during the battle with 2B.
