If one crudely and roughly quantified the difference in combat power between the Great Mage and this hell demon, the Great Mage's strength was probably around one hundred, while the hell demon's was roughly two hundred.
It looked like only a onefold increase, but anyone who had done deadlifts or weightlifting knew that once they reached their upper strength limit, even adding five pounds would make the weight impossible to pull or lift.
This was not as simple as "one plus one." The gap looked like only double, but in reality, it was enormous.
Yellow smoke poured from the hell demon's mouth. With a wave of its hand, a massive burning meteor shot out of the Mist Wall and slammed viciously into the Radiance Barrier.
The Radiance Barrier burst into blinding light in an instant. It protected the people inside, but cracks also appeared across the barrier itself.
The Great Mage's expression changed drastically. He raised his staff and unleashed the most powerful spell he could use: Apocalypse Flame.
The flames shooting from the staff condensed in midair into the shape of a book. Then it slowly opened, and countless flames surged from its pages. In an instant, the battlefield was submerged in fire.
The stench of scorched protein filled the air!
The weaker monsters turned into charcoal in a very short time. Some powerful monsters were still resisting. The Great Mage stared at the hell demon, and the sliver of hope in his heart shattered into pieces.
The hell demon was surrounded by a thick layer of black smoke, as if it had suffered no damage at all.
As it raised its right hand, even more meteors shot out of the Mist Wall.
After resisting two strikes, the Radiance Barrier finally shattered!
More monsters rolled out of the Mist
