A strange and suppressed voice came out from Xasalun and Xarosa's mouths.
A glaring blood-red glow blossomed in their eyes. A thick spiritual aura spread out from their bodies.
The souls of the two Blood Slayer Race dark apparitions skyrocketed in a strange way.
More and more souls flew out of the Blood Soul Banner without stopping.
There seemed to be countless souls in the Blood Soul Banner.
After some time, the entire hall was filled with countless souls. The wails of the evil spirits were heard continuously.
On the other hand, Xarosa and Xasalun's spiritual aura rose continuously. They climbed all the way from mid-tier devil emperor to high-tier devil emperor.
This was an extremely violent method. It was like stuffing another material into their souls. Although they were all spiritual power, they didn't come from the same source. It was hard to digest and would definitely leave a serious injury in their souls.
However, Devil Titan Xue Can didn't care.
