They had already cleared the area of grass and packed the ground.
On top of that, they had drawn a huge magic circle with white pebbles.
In the center of the magic circle was a severed white cow's head, with a magic stone placed on its forehead.
It was a 10th-grade magic stone.
Although the mages could naturally use silent casting magic, chanting was necessary for great magic.
"I, Alcandura, de magica."
"I am Ishen, de magica."
"Dezaka de magica!"
The ground's vibrations became more intense, and the rushing monsters came closer into view.
Nevertheless, the mages maintained their composure.
As they continued to mutter in rune language.
Whoosh!
The white cow's head spontaneously burst into flames.
Even the magic stone that doesn't burn in fire started to burn.
Powerful mana gushed out from there.
It was amplified by the magic circle.
