The next day.
Zhou Changqing came to the valley floor as usual.
The dazzling, incandescent lightning bathed his entire body in silvery white, while countless interweaving, leaping bolts cast their images into his eyes.
Their reflections made it seem as though thunderbolts were darting through his pupils.
He gazed at the raging Thunder Sea before him, confined by an invisible force that prevented it from advancing any farther.
Rather than sitting down to temper his body, Zhou Changqing studied it, his thoughts beginning to turn.
I wonder how this Thunder Sea formed. There must be something special about it. Should I investigate?

Apart from a very few powerhouses who had the strength to get to the bottom of it...
Everyone else, even a Peak Dou Emperor, would likely be helpless before this vast Thunder Sea.
