BoooooooooooooooooooooM!
The explosion caused by the self-destruction of a Rank Six dragon was no joke.
The moment the dragon self-destructed, violent energy waves erupted outwards in all directions, wiping out everything in their path.
The defensive barrier that covered the capital of the empire couldn't withstand the power of self-destruction, and cracks appeared all over it. The magic cannons that were part of the defensive barriers collapsed, and the attack formations shattered.
Seeing the rapidly spreading cracks in the barrier, the faces of all the demons inside the capital turned pale.
The demons in charge of the defensive formation increased the output of energy into the barrier to the maximum limit possible, but even then...
Crack... Crack...
The spiderweb-like cracks spreading on the barrier didn't stop and the barrier became fragile like glass. In just a few seconds, under the horrified eyes of the demons...
Crack!
