As for mental strength resources, there was no other option. Such resources were high-priced, so he had to rely on soul fruits to accelerate cultivation.
On this thought, Gary Smith handed the box containing the nether soil to Mousie, who happily scampered off to sprinkle it on the root tendrils of the Thousand-faced Soul Tree.
Hiss hiss!
Quickly, the special nether soil merged into this once desolate world, emitting a tranquil aura, as if it was a peaceful land comforting the spirits of the deceased.
"Master, the Soul Tree has grown!"
Mousie flagged a reminder. Gary Smith nodded, clearly seeing the growth of the Thousand-faced Soul Tree.
This little nether soil had taken effect. If he could treat it like fertilizer and accumulate it daily, won't it grow into a big tree quickly?
By then, the tree would be brimmed with numerous soul fruits. He could indulge on them every day!
