Great Battle

At This Moment, the skies above Penglai Island were already shrouded in black cloud stretching ten thousand miles, as though night had fallen.

Within those pitch black clouds, white flashes flickered from time to time, accompanied by rolling thunder. The spectacle was immense, like a mythical war from the ancient era that belonged to the heavenly vault.

The black cloud pressed lower and lower, and the atmosphere grew increasingly oppressive. Millions of living beings across Penglai Island trembled at this moment, fear written across their faces as they looked up at this scene, like a heavenly disaster.

The next moment, an incomparably majestic voice pierced through layer after layer of obstruction, as though it reached the ears of Heaven itself:

"Thunder Duke, lend me your aid!!!"

Rumble!!!

In an instant, white light flashed like lightning and blue light flooded like the sea. Terrifying thunder descended from the sky, instantly drowning everything!

At the summit of a Mountain City on Penglai Island, endless lightning radiance engulfed the peak. Terrifying power ran rampant, reducing the Mountain City buildings below—which had long since been emptied of cultivators—to ruins!

Countless bolts of lightning poured down from Above the Nine Heavens, blanketing the region like a waterfall. Amid the endless thunder, a weathered youth stood within the sea of lightning. A Thunder Mark showed between his brows, and a terrifying pressure radiated from his whole body.

In his hand, he held a seal the size of his palm, seemingly forged from the finest Fine Jade. Cloud Seal Heavenly Script was engraved upon it—ancient writing from the Ancient Period that resonated with the Worldly Laws. Countless arcs of Lightning Radiance coiled around it, and rolling thunder resounded for a thousand miles.
