Su Changkong's brow furrowed tightly. Demon Monsters could not be killed? They would be reborn as the years passed? What was the principle behind this?
Su Changkong did not understand. Not to mention himself, even a Martial Saint with Great Divine Power might not be able to figure out the reason.
But Su Changkong had a premonition of something ominous. He had previously heard from the person in the mirror that the Mirror Master had died because of the 'Monster Soul Mark' of the Demon Monster King. Even the Mirror Master had fallen due to the Monster Soul Mark, not to mention himself. Wasn't his current situation the same as the Mirror Master's?
"Is there a way to remove this Monster Soul Mark?"
Su Changkong immediately inquired.
