"Silence!"
Suddenly, the sky started changing color, with the archmage's body illuminating a blinding light.
All of the spells on the other side had vanished, along with the archmage and the emperor's barrier.
All three of the kids could feel their mana being suppressed to their bodies, unable to exert outward at all.
"You all really think you can beat an archmage?" The emperor laughed as he drew out a sword.
The other groups started to panic as all of them seemed unable to cast anything at all, either.
With the emperor walking closer and closer, the groups of mages started to scatter all over the place.
A few stayed, casting an elemental sword of their own in an attempt to fight back.
Yet, despite the numbers advantage, they were no match to the emperor as a clean slash and stab killed them off one by one.
The five of them on the rubble could see the elemental sword would instantly disappear when their hands were cut off.
