When Auron threw his spell towards the door, a glowing rune was appearing in the door. The glowing rune quickly disappeared afterward. Meanwhile, the spell that Auron launched also vanished at the same time as the disappearance of the glowing rune.
Auron cursed, "F***, a nullify formation."
It was not a strange thing to find a nullify formation in a big city or in the kingdom. However, it was weird to see a nullify formation deep inside the forest. Moreover, it was a high grade one.
A nullify formation was divided into three grades. A low grade could only cancel weak damage spells. If the spells were too strong, then the formation would be broken.
At the same time, a medium grade almost the same as the low-grade formation. The difference was in the damage limit that it could hold.
