A Complex Source Vein

"That's certainly a big Immortal Stone." Lin Mu looked at the large crystal which was entirely composed of High Grade immortal stones. 

They had grown so much that they had now fused into a single entity. 

"Just a thousand years or so and they might have turned into Peak Grade immortal stones perhaps." Xukong spoke up seeing the large chunk.

"Mmhmm… if this place was left untouched it might have really become a Peak Grade Immortal Stone mine. But for us, even this is enough." Lin Mu replied.

He closed his eyes for a moment before activating Spatial perception. With that, he gazed directly at the large chunk of High Grade Immortal stones. Or more accurately, Lin Mu was trying to see where the source vein of the entire mine was exactly.
