There's no actual chapter 314 in 'Tales of Demons and Gods', not yet anyway. The light novel and webcomic are way behind that number, and Mad Snail's update pace is... legendary for the wrong reasons. I think you might have seen a faked chapter title or a clickbait site. Those fan-translation aggregators sometimes create phantom chapters or compile spoiler summaries from the author's blog or Q&As and label them with fake numbers to get clicks.
If you saw a '314' that had major plot reveals, it's almost certainly not a real published chapter. It's more likely a compilation of future plot points Mad Snail has hinted at over the years, like Nie Li's eventual confrontations with the Sage Emperor or the fate of the Tiny World. I got burned once clicking on a 'chapter 300' that was just a poorly translated list of spoilers from a forum post, and it ruined a few big twists for me. Your safest bet is to stick to the officially translated chapters on platforms like Webnovel or the comic on Tapas—they're only in the 200s, and anything claiming to be beyond that is spoiler territory masquerading as content.
