Wang Teng held the crystal skull in his hand and used his spiritual power to sense it. He only felt at ease when he confirmed that the pope was gone.
The pope was a crafty guy. Wang Teng didn't know if he had other paths of retreat. But currently, it looked as if the crystal skull was the last method he could use.
It made sense. Spirit was something profound. He hadn't heard of any methods from Earth or the Xingwu Continent that was able to protect a person's spirit without the body.
Even the Abyss Burial skill he got on Mount Saint was just a special battle technique with an extremely low success rate of hitting the soul out of one's body. Also, it wasn't a normal method. It would cause great damage to the soul of the body.
Abyss Burial was a forceful separation of the soul from the body. The damage it caused to the soul couldn't be healed.
