From inside the Dragon skeleton, the Holy Spirit God screamed out, continuously releasing soul forces with the hopes of changing the situation.
Suddenly, the Icy Crystal Bone Dragons, which had been tied up by Shi Yan’s Sea of Consciousness, violently wriggled while their soul forces were gradually increasing.
However, they still underestimated Shi Yan’s soul competency.
In the abandoned land, Shi Yan had continuously studied different magical spiritual Upanishads of the Demonic Sound Clan. Moreover, he had also taken Pan Zhe and the other warriors to be his experimental human test subjects. Although his understanding of the souls was still not as well as that of Yi Tian Mo and the other leaders of the Demonic Sound Clan, his perception of the spiritual Upanishads had been much more profound if compared with ordinary people or even some normal pagans of the Demonic Sound Clan.
