When the time comes, I'll find an opportunity to personally verify whether the lone Ninth Tiers among these powers are truly Langya Incarnations.
After all, Yang has said before that he can guarantee if they're not incarnations, the Compass will not show them as such.
But if they are incarnations, with the Compass of that generation, it is indeed possible to find a way to shield it, causing the Compass not to detect them.
Of course, releasing that generation's Compass was intentional.
You can't just come out with a perfect detection Magical Treasure and drive people into a corner; you have to leave some loopholes for them to exploit.
If they released the second generation right from the start, the chief director of Dong Chang would be having a meltdown right now.
Forcing such people into a corner with no way out, he'd probably throw caution to the wind from then on.
Think about it, the known Ninth Tier Langya Incarnations discovered so far actually number three.
