Chapter 457: Activate Black Jade

No matter the creature, the heart is always its core.

It is the source of a creature's vital essence.

Thus, there must be a significant amount of Primordial Stones within this heart.

If it were possible to find a mass of Primordial Power Veins, then his Black Jade would undoubtedly activate.

Thinking of this, Xu Nian could not contain the excitement in his heart and hurriedly flew toward the Primordial Power Veins.

Soon, Xu Nian arrived at the top of the mountain.

At first glance, the mountain looked no different from any other.

If he hadn't known beforehand that this was the heart of the Azure Dragon Divine Beast, Xu Nian might not have paid it any additional attention.

Because Spiritual Sense Power could only penetrate three meters into the surface of the earth, he couldn't inspect what exactly was inside the mountain.

"Buzz!"

Xu Nian immediately activated the Gray Dragon Eye, delving deeper into the mountain.

This investigation left Xu Nian utterly astonished.
