Heavenly Profound Sect, Heart of Thunder

"The Thunder Lake was filled with Thunder Power. It must have been where the disciples of the Ancient Thunder Palace cultivated back then."

Mo Yu lightly touched the lake water with his palm. Strands of Thunder Power immediately wrapped around it before drilling into his palm through every opening, leaving his hand slightly numb.
