I just recently went to Scholar’s Advanced Technological System page and noticed that it only has one chapter in the release section which was tagged as ad-walled. From I have seen in the original website chapters 01-39 are free, so I was wondering why it wasn't in the release section. I noticed the same thing for 48 Hours a Day so I'm guessing there must other Qidian series that have the same problem.
For these situations you need to file a report. Go to your user profile (on NU, not your forum profile), and click "Report Problem". Then explain the situation there. Here's a pic for reference:
sometimes qi will release the paywall become free, but will lock it again~ maybe for advertising stuff~ consider it kinda hassle to link it again then re lock again if locked again it usually forgotten after first lock~ you can report problem or manually link it to NU tho~ btw if Locked again someone will report it so the cycle complete~
