Yan Xiaobao needed a lot of time to create this black energy, but since the unknown tomb, he hadn't engaged in such a serious battle. Since he hadn't needed to use it recently, he slowly created and accumulated more of this destructive energy. Although it harmed his heart, he also understood that it was one of his trump cards, and if their trial continued in this manner, they were likely to lose this battle.
"If we need it, I'll use it." Yan Xiaobao said decisively to Lan Feng; if possible, he would rather avoid exhausting his energy. His clone was also likely to use the black energy. If he indeed possessed it, then it was likely he would use it simultaneously without giving it an edge. Although he could use this black energy, he wasn't sure if he could defend against it.
