Ediana is doing a good job making the atmosphere lively inside the city but outside is livelier because of these more than ten thousand strong super beings' joint attacks.
The more they attack, the more they are surprise on how hard the barrier in front of them and can't even be shaken. Ten more joint attacks were made before this Head Keeper finally gave the order for everyone to power up and go all out.
As soon as the words were heard, all the strength skyrockets; focusing all of it to their next attack. Together, they are about to lauch the accumulated energy in their own killer moves when a bullet-like projectile that is made up of concetrated pure energy was too fast to penetrate one's head. It didn't stop there and killed the other super beings behind.
