Lin Dong's hand took on the shape of a claw as a suction force suddenly erupted from within his palm. The thunderbolt core that had just surfaced from within the stone cave immediately whistled out. After which, it was grabbed by him.
"The fourth one!"
Lin Dong grabbed the thunderbolt core and felt the surging pure lightning energy within it as excitement involuntarily flashed across his eyes. In less than ten minutes, he had already obtained the fourth thunderbolt core. Such a haul was already very bountiful.
After keeping this thunderbolt core, Lin Dong glanced towards Mu Lingshan in front of him. At this moment, the latter was darting all over the place in an excited manner as she searched for thunderbolt cores. Wild and violent Yuan Power fluctuations continued to ripple over from even further away, and it was possible to faintly hear the sounds of battle.
