Creak!
As the vortex formed within the lightning lake, a silver ball of light slowly rose from within, before quietly floating in front of the absent minded gazes of Lin Dong and Liu Xiangxuan.
Yet another thunderbolt core!
Behind Liu Xiangxuan, those experts from the Mysterious Sky Hall were also in slight shock as they stared at the scene before them. Obviously, never did they imagine that another thunderbolt core would surface from the lake.
After being in a dazed state for only a short moment, they abrupted glared at Lin Dong and Mu Lingshan. Before this, Lin Dong had already obtained a thunderbolt core. Hence, this newly surfaced one definitely had to land in the hands of their Mysterious Sky Hall.
