Great Wilderness Four Extremes Qi Demon Scripture, an Emperor-Level Demonic Cultivation Technique!

At this moment, the Ten Extremes Demon Lord was so furious that his lungs were about to explode.

A trace of blood-red appeared in his eyes, and the aura around him grew increasingly terrifying, brimming with killing intent!

Here, he had already gained the upper hand.

It seemed that before long, he would be able to directly slay those three immortal old Half-Saints.

When that happened, none of the people from the Limitless Sacred Land here would escape!

The Ten Extremes Demon Lord himself was already at the Peak Half-Saint Realm. His methods reached the heavens, and he could slaughter all before him!

He had been just one step away from total victory, yet such an accident had occurred.

Even with his strength, it was difficult for him to imagine what exactly had happened.

Who possessed such formidable strength that they could kill Tu Kangcheng and Ling Fei?

Even combined, those two could not be slain by a Fourth-Level Great Ability Realm expert.

Forget the fourth level—even against a Fifth-Level Great Ability Realm expert, the two of them could join forces and escape!

The Ten Extremes Demon Lord believed those two were not fools. They would not fight to the death; if they could survive, they would certainly choose survival first.

So just how powerful was the enemy they had encountered? Could the other party truly be as strong as the Sixth-Level Great Ability Realm?

"Devil Master, Elder Cao is nearby. I'll notify him at once!" someone said.

Elder Cao was a Great Ability Realm elder of the Ten Extremes Demon Sect. His strength was formidable, and he had reached the Sixth-Level Great Ability Realm!

"Good! Have Elder Cao go investigate! There should be no issue with Elder Cao's strength!"

Very soon, someone sent word over.
