After bidding Yao Lao farewell, Xiao Yu lingered no longer. He left the place and headed up through the magma.
The exchange with Yao Lao had brought Xiao Yu a rich harvest.
A seventh-tier Great Nirvana Pill formula was the payment they had agreed upon earlier.
What he obtained in the subsequent exchange was an eighth-tier Bone-Growing Blood-Fusing Pill formula, a resurrection method, and a soul cultivation art-the Taiyi Soul Art!
There was little to say about the resurrection method. The most precious thing he had gained this time was the Taiyi Soul Art.
According to Yao Lao, this soul cultivation art was exclusive to the Pill Tower. Its value rivaled that of a high-grade Earth-tier cultivation method, if not surpassed it.
This was exactly what Xiao Yu needed. His soul power had always grown naturally, increasing as he broke through to higher cultivation realms.
Now it had reached a bottleneck. Without outside assistance, breaking through it would likely be difficult. He might have to wait until he reached High-Rank Dou Zong, or perhaps even Dou Zun.
As for soul realms, Xiao Yu only knew what he had learned from the original story: there were four realms-Mortal, Spirit, Heaven, and Emperor.
Beyond that, he knew nothing at all. Now that he had this soul cultivation art, it would be an enormous help in strengthening his soul power in the future.
It would also greatly help improve his pill-refining abilities.
From the Taiyi Soul Art, Xiao Yu learned that his soul was currently at the peak of the Mortal Realm.
With the Taiyi Soul Art, Xiao Yu believed he would soon break through to the Spirit Realm. Then he could attempt to refine eighth-tier pills.
Only once he could refine eighth-tier pills would he be able to use that resurrection method.
