The Thunder Emperor's world-shaking Dharma Form erupted like a platinum giant. His long hair stood on end, white strands dancing wildly like heavenly lightning.
"Arrogant fool! If I could kill you once, I can kill you a thousand times! Don't think becoming an Immortal King lets you do as you please. I've killed Immortal Kings before. Great Dark Heaven Realm!"
Immortal King Le Yu had rarely acted since the Immortal Ancient War, but no one doubted his strength. He had slain an unrivaled Immortal King, and his immortal kingly aura shook heaven and earth. Endless demonic energy blotted out the sky and sun, threatening to swallow his opponent. This dark energy resembled the strange secret power in the Boundary Sea, yet was even more terrifying, devouring all vitality. He had nurtured it within his body, using endless death intent to peer into the Great Dao of heaven and earth. Its terrifying might swept forward.
Facing this attack, the Thunder Emperor unleashed his divine essence and raised a hand, pointing a finger. The true intent of lightning gathered at his fingertip, evolving into life-and-death ultimate intent.
"In the past, I wouldn't have dared take a Heaven-Swallowing Secret Art like this head-on. But I'm no longer who I was-and you don't seem to have improved at all."
"Laughable! Then come and see whether I can kill you!"
The golden immortal radiance covering Immortal King Le Yu was stained black. Like a black sun, he radiated endless darkness. Stars melted, and the vitality of all things was devoured, reduced to ashes. Even time was corroded and could no longer flow. Heaven and earth plunged into darkness.
"Heavens! This is the King's World-Destroying Secret Art! Quick, fall back!"
"Do you want to die? Retreat!"
An immortal roared, instantly issuing orders to warn the cultivators
