As the air in the training hall became heavy, Cale's body released it's chaos energy. The entire training hall, which was resistant to SS level attacks, was filled with chaos energy. Chaos energy, which would have suffocated anyone else, swirled around Cale with the effect of being released.
Cale knew that even if he controlled the chaos energy, there was a force that would attack him at any moment. Therefore, to contain it, he had to take care to develop the skill of Unlimited Void.
Cale saw the chaos energy turn into a shadow silhouette that resembled him. Cale and the figure faced each other. When the shadow figure appeared in front of Cale, Cale used his void step and backed away.
A long trident formed in the shadow figure's hand. As it twirled it in it's hand, chaos energy surged and flowed towards Cale.
