Although Xu Zimei killed the mysterious creature with ease.
In reality, most people are unaware of things like Soul Seeking or the peculiar physical body.
This also means, in the eyes of many people.
The mysterious creature is considered immortal.
So regardless of one's strength, everyone is cautious when facing the mysterious creature.
After all, if you want to find the mysterious creature's physical body, you first need to study the Taoist Technique of the Old Universe.
Second, you need tracking skills like Soul Seeking Secrets.
However, few choose the Old Law.
Because firstly, the Old Law is outdated, meaning it has lost its glory in the era of the New Universe.
Secondly, the Old Law of the Heavenly Burial Grounds has been severely interrupted.
In such cases, you might learn the upper part without the lower part.
The difficulty of seeking it is considerable as well.
Combining these factors, even fewer people study the Old Law.
