Chapter 649: Integrating the Unperishable Flame

As if from a different space, the vast sea of purple fire swept through with a fierce aura of devastation above the Sovereign Sea.

Mu Chen had experienced a bitter month of suffering. However, the majestic spiritual energy of the Sovereign Sea was now boiling hot. A kind of indescribable heat surged as if it aimed to burn him.

What an overwhelmingly fierce Unperishable Flame…

Mu Chen's spirit gazed solemnly as the scene unfolded before him and the Unperishable Flame revealed its true extent of extraordinary power. He finally realized how Nine Nether had been letting him off easy in the previous month of cultivation.

If Nine Nether had murderous intent towards him in this moment, his Sovereign Sea would have been instantly burned to nothing.

No matter how brutal you are, I will thoroughly integrate you today! Fierce determination flashed in Mu Chen's eyes as he immediately took a deep breath and waved his palm.

Boom!
