Initially, the entire Douglas Country made a concerted effort to tackle the evil technique of the [Heavenly Demon Altar], aiming to locate this method, understand its origins and connections, and find a way to break it.
Regardless of whether it was Douglas Country or Regan Kingdom, at that time, neither necessarily had bad intentions; it was mostly an attitude of "one can never be too careful." [Heavenly Demon Altar] plagued both countries' lands, and if we didn't try to find it, what if the other side found it and used it against us...
However, as time passed, everyone felt that they couldn't find it. In particular, the last magic treasure pot used by that cook, the true "Heavenly Demon Altar," might have been a Tire-9 Treasure before the Heavenly Track Reversal. Under this evil technique, it somehow bypassed the limitations of the Heavenly Track and barely reached Tire-8 power. It's important to know that this was 600 years ago when the Origin Resurgence hadn't even happened yet.
