The punch brought Jack's attention to something crucial, wasn't this no different from the [Void Strike] his master taught him? Well, except for the part where it used a completely different type of energy. Still, it was the same technique in his eye, except for the fact that his opponent seemed to have mastered it to a better degree compared to him.
Either way, Jack shook his head, pushing those thoughts aside. Adjusting himself, Jack thought about a way to effectively damage his opponent. Soon, an idea came to his mind, causing him to run to the nearest tree.
With no weapon, Jack was forced to pull a tree branch as a medium to contain his raw mana. Although he understood he was at a disadvantage since his enemy had two weapons, he had no other option but to do that trick.
