Seeing the blue ball of fire, Greene knew whose attack it was.
"Roland!"
After Greene roared, he subconsciously used Imprisonment on himself.
The translucent magic barrier was frighteningly large, enveloping all of the two hundred or so Mages with him.
Then the blue fireball blasted over.
Where it passed, the night was as bright as day.
The air was rising and distorting.
With terrified eyes, all the people in the Spatial Magic Tower looked at this blue fireball flying over.
Greene was a Legendary Mage, and he was able to cast Imprisonment three more times in the short three seconds it took for the blue fireball to reach them.
The magical light film formed by the four layers of barriers was already almost a centimeter thick.
All the people present were knowledgeable, and they naturally knew what four layers of level-five defensive barriers meant.
They felt a sense of security and a little peace of mind.
