First, "Shinseki" is likely "Shinsekai" which means "New World". "No Ko" is "Child" or "Girl". "To o Tomari" – "Tomaru" means to stop or halt. Maybe the user misspelled or mixed parts. "Rule 34" is a meme referring to explicit content related to anything, so Rule 34 would imply there's NSFW material. The user might be asking about Rule 34 images related to this anime/manga.
