A Minor Body Problem
The azure crystal wasn't just a mere container for the rich energy found within it. No, the azure crystal itself was a crystallization of the energy condensed together.
In other words, the azure crystal was pure energy.
Furthermore, Vaan discovered this pure energy could be manipulated by men, unlike mana. Simply by holding the azure crystal, he could extract its energy with a thought.
At first, control of the energy seemed weak and limited. But once it flowed inside and cycled through Vaan's body, it became increasingly easier to manipulate over time.
In essence, the level of control was directly related to the level of energy refining.
Nevertheless, the most important discovery wasn't the ability to control this energy but the potential benefits it granted to life.
Vaan had subconsciously cycled the unknown energy through his body according to his Heavenly Formless Dragon Art.
It was only a single cycle, but he had already reaped countless benefits.
