In the void, a mass of black mist first emerged out of thin air and then rapidly expanded in its rolling motion. Within a few breaths, the surging black mist expanded to a diameter of a kilometer.
After expanding to a kilometer, the surging black mist was tinged with a blood-red aura. Gradually, as the rolling aura expanded more and more, it grew so large that it seemed to have no visible boundaries.
Its size was definitely no less than tens of thousands of miles.
The expansion of the rolling aura continued for a full 15 minutes until the rolling aura completely transformed into a thick dark red blood-colored demonic qi. Suddenly, a phantom of a palace appeared amidst the blood-red demonic qi, faintly discernible.
At that exact moment, the blood-red demonic qi ceased its surging motion.
But at that very moment, the small Demon Soul Hall hanging on Ye Zhen's chest suddenly became unbearably hot.
The high temperature was so intense that Ye Zhen let out a cry of pain.
