921 Stir-Fry the Demon Frog!

The high, black mountain outside the Hidden Dragon Royal Court 

In the center of the peak, a giant figure sat inside a massive cave. That man had so many demon marks winding around his body, which made him look even fiercer.

He was no one else but the strongest demon king, who was cultivating in seclusion.

Being sealed in the bronze palace for ten thousand years, the strongest demon king's cultivation base was a little stagnant. Today, he must continue cultivating to regain his body's functions and his peak condition.

Boom! Boom! 

In the cave, thick Nether energy wound around. It was so thick that it had almost become real matter, filling the entire space.

The strongest demon king was there. While breathing, thick energy moved between his nose and mouth like long dragons.

Suddenly, the strongest demon king opened his eyes, which were deep and wise like the magnificent starry night.
