Accelerating his pace to catch up, he soon saw the stone in front of the trio, the stone was translucent with a weird green light, Zhang Long couldn't help but breathe sharply and his gaze contracted violently. Taking advantage of the fact that the three of them were not yet close to the crystal stone, Zhang Long rushed over with a high shout and directly grabbed the crystal stone. The cave was pitch black, and the three youths were then startled by Zhang Long's sudden ghostly cry, only to see a figure grabbing onto the stone, and the stone violently began to turn red, giving off a very unpleasant feeling. The three of them glanced at each other and then prepared to retreat, but it was all too late, the three of them were directly fainted when they were brushed by the red light spreading out from the stone. At this time, Zhang Long's situation was also very bad, the whole body veins straight up, a stream of energy along the arm that grasped the crystal stone surged straight to the brain.
