This is actually a body refining technique.
It seems that Quentin Ziegler is cultivating this "Blazefire Vajra Technique".
Body refining techniques are extremely rare on the Continent of Aethelgard, and are renowned for being difficult to train and slow to cultivate.
Cultivating a body refining technique will continuously strengthen the physical body, endowing it with various miraculous abilities.
The physical body is divided into nine grades according to its strength.
First grade is the weakest, ninth grade the strongest, and each grade is divided into Small Success, Great Success, and Perfection levels.
However, the path of body refining is not a standalone path, but a supplementary type within martial arts, similar to the path of inscription refining which supports martial arts.
Because if the physical body is not integrated with martial arts, its power cannot be fully unleashed.
Take the First Grade Body for example, it does not correspond to the Warrior Realm.
