Two weeks passed...

After Nie Tian used up all of his soul crystals, his second sub-soul came to form.

The new sub-soul was fused with his lifetime understandings of wood power, including the profound mysteries of Heavenly Wood Heal and the Wood Thriving Formation.

Now, he had a flame power sub-soul and a wood power sub-soul that could derive enlightenment of the two types of power on their own.

He had a feeling that in order to enter the Profound realm, he would have to form his third sub-soul and fuse it with his lifetime understandings of star power.

Only at this moment did he finally realize the true value of soul crystals.

Without soul crystals, he would have to go back to channeling soul power from the starry river through the well-shaped heavens in the Realm of Maelstrom.
