Combining all the comprehension that Huang Yueli had in the past with the contents that she read from the manual today, she roughly had a conclusion.
In Soaring Heavens Continent, the main element that determined the grade of the Profound Armament was based on the materials that were used to refine the Profound Armament.
An Armament Master's innate talent might be important, but the fire and metal attributed to Profound Energies were mainly used to smelt materials, control the flame's temperature and also help the Profound Armament to form its shape.
But refining Spirit Armaments was another thing.
The thing that decided the Spirit Armament's grade was not the materials, but the Spiritual Armament Master's innate talent, ability, and the control of one's Profound Energy.
Spirit Armament materials were just a retainer that was used to contain the Spiritual Armament Master's Profound Energy.
