After setting up the task, Xiao Yang shot straight toward the Three Great Dragon Kings.
Previously, he had not gone all out. Merely relying on the physical strength of the Dragon Transformation Art and the newly learned Sky Tearing Claw, he had already suppressed the Three Great Dragon Kings.
If Xiao Yang unleashed his full strength now, it would be not just that.
He directly activated the Heavenly Flame Three Profound Transformations.
The next moment, Origin Fire surged out from Xiao Yang's body.
His aura began to soar.
Late Three-star Dou Saint...
Peak Three-star Dou Saint...
Early Four-Star Dou Saint...
Just like that, Xiao Yang's strength actually surged all the way to the Late Four-Star Dou Saint!
The Heavenly Flame Three Profound Transformations had directly raised Xiao Yang's cultivation by one star!
One had to know that he was now a Dou Saint!
And the Heavenly Flame Three Profound Transformations was not even complete!
If it were the complete Heavenly Flame Three Profound Transformations, Xiao Yang could definitely rise to the Five-star Dou Saint!
Sensing the surging aura around Xiao Yang, the Three Great Dragon Kings' expressions changed at once.
When they had seen Zi Yan put away the Dragon Slaying Sword earlier, they had felt somewhat delighted as well.
They had also noticed the streak of grayish-white in Zi Yan's hair.
But if Zi Yan risked her life and insisted on killing them regardless of the cost, they would certainly not escape death today.
After Zi Yan put away the Dragon Slaying Sword, they had been overjoyed.
But now, upon sensing Xiao Yang's rapidly rising aura, the Three Great Dragon Kings' expressions darkened once more.
"Must you really kill us all?"
The South Dragon King said with red eyes.
There was a trace of madness in his gaze.
