The two searched for one day before Shen Xu saw a similar stone in one of the books.
"I found it." He exclaimed and subconsciously tugged Zhen Yuan's sleeve.
"Ayuan, It's a soul marrow stone." Hr said.
Like soul water and soul stones, the soul marrow stone was a soul refining treasure that could increase and purify soul power.
After ascending to the immortal realm, the two enhanced their body and qi cultivation but hadn't had an opportunity to cultivate their soul power.
With the soul marrow stone and other soul treasures including soul nourishing fruits, Zhen Yuan was certain they could successfully evolve their soul and improve their cultivation.
"It says here that the soul marrow is within the stone, and can't be extracted with ordinary methods. We need to soak the stone in soul water to shed the outer skin." Shen Xu said and Zhen Yuan nodded in understanding.
For others, soul water was a rare treasure and they would be reluctant to use it to soak a stone.
