Death within the Spirit Realm was not true death; it merely damaged one's soul. However, such damage was extremely severe, and the only way to heal the soul was to hunt a special type of creature in the Spirit Realm—Soul Beasts.
After a Soul Beast died, there was a chance it would leave behind a crystalline core. The races of the Myriad Worlds called such cores "Soul Cores."
After consuming a Soul Core, injuries to the soul would fully recover. It could even improve the quality and resilience of one's soul.
Soul Beasts were not particularly rare within the Spirit Realm. There were many Soul Beast gathering grounds near Eight Desolations Star City. However, while Soul Beasts themselves were common, killing them was extremely difficult.
Within the Spirit Realm, most divine abilities could not be used, which prevented the various races from fully displaying their strength.
Although there were experts skilled in soul attacks, Soul Beasts were not easy to deal with either. Moreover, they lived in groups. Provoking one could draw dozens, or even more.
Many people failed to hunt Soul Beasts and were instead surrounded and killed by them.
Furthermore, the chance of a Soul Beast dropping a Soul Core after death was not high. It could take dozens or even hundreds of Soul Beasts for a single Soul Core to drop.
Under such circumstances, Soul Cores were extremely scarce and valuable items within the Spirit Realm. Ordinary races and weaker cultivators found it exceedingly difficult to obtain them.
Ye Yue had smashed Jiu You Chao Shan's head apart with a slap, injuring his soul. He had to consume a Soul Core to recover. Given the Nine Nether Dynasty's strength, producing a Soul Core was not difficult, but it was still enough to make the dynasty ache.
