"Thunder?" Ji Dong's eyes suddenly narrowed. What did thunder represent? If it wasn't natural thunder, then, in his memory, only Thunder Emperor Frey could produce such a sound. This must, at the very least, be the sound of a top-tier killing move being fully released. It could even surpass that of a top-tier kill technique. If he hadn't encountered an extremely powerful opponent, why would his brother do this?
"It seems my brother has encountered a strong enemy. We need to move quickly." Ji Dong no longer hesitated, grabbing Lan Bao'er's hand and accelerating instantly. With the super flexibility of the Flying Serpent Transformation, his body released explosive power, charging into the range of the eighth level of Holy Evil Island like an arrow.
