The manual started with a standard introduction of demon beasts and then moved on to their classification based on their lethality and power.
There were six grades that roughly categorized such deadly creatures and three small subdivisions; low, mid, and high, to further classify.
Grade one demon beasts could match Body Tempering practitioners in terms of power. For example; the craoca we rode on was only a mid-grade one demon beast.
Grade two was not something a normal Body Tempering practitioner could handle. High grade 2 demon beast could even fight against Meridian Opening stage practitioners.
From grade 3, however, things get tricky. A mid-grade 3 demon beast might overpower a peak Meridian Opening practitioner.
So much so that high grade 3 beasts could only be handled by Qi gathering cultivators. The Syul demon snake from Pinchu lake was also just a high-grade three demon beast.
