"Hahahaha, hahahahahaha!" A strange laugh resounded throughout the dimension. The three of them immediately looked nervous. Little Fire's body had already tightened immediately, while Meatball on Yun Feng's shoulder also turned its body to one direction as its grape-like eyes rolled around.
"Who's that? Come out here!" Yan Yu shouted. There was no more sound in the air again. Yan Yu felt that the invisible sound waves suddenly turned into a lifelike fist, directly punching his body through his fighting energy defense!
"Hm!" Luckily, the bodies of the Dragons were strong. This attack made Yan Yu bend his body in a bit of pain. If the attack hit a human, it would probably penetrate the body.
