Been a while since I checked the final chapter, so grain of salt and all that. From what I remember, the manga wraps up the current arc with Nie Li securing the foundation for the future, but it doesn't adapt the full web novel ending. It's more of a 'to be continued in the source material' stop.
Some fans were kinda frustrated it felt truncated, like they ran out of steam or maybe had production issues. The last panels have a hopeful tone, with the core group looking toward the horizon, implying the bigger journey is still ahead. If you're invested, you'll probably need to jump into the novel to see the actual final battles and the fate of the Tiny World.
Honestly, the manga's conclusion felt a bit like a season finale, not a series finale. It answers the immediate threats but leaves all the cosmic-scale stuff hanging.
