Faced with Wu Yang Ancestor's terrifying attack, a cold light flashed through Zhou Yu's eyes.
He instantly put away the shattered Red Blood Sword, then with a wave of his hand, a black stone appeared before him.
Immediately after, Zhou Yu activated his True Yuan and cast a Technique.
In an instant, the black stone rapidly expanded.
Back when Zhou Yu was still in the Golden Core Stage, he could only enlarge the Immortal Black Mountain to a little over a thousand feet, and even then, using it would consume most of his True Yuan.
But now it's different.
Today, Zhou Yu is a Nascent Soul Realm cultivator, and the quality and quantity of True Yuan in his body has multiplied compared to the Golden Core Stage.
At this moment, he no longer needed to worry about not having enough True Yuan to activate the Immortal Black Mountain.
The Immortal Black Mountain instantly grew to a thousand feet.
