Chapter 522: Attack on Sky Fiend Group

Sky Fiend Headquarters was spread in an area of almost 2 sq.km. The over twenty buildings and factories were evenly spread, hosting thousands of workers, including mutants and researchers.

Ever since Joshua unleashed the alien creature on the city, he activated the advanced state of the art.

Military-grade rockets, automatic laser artillery, and battle droids were on stand-by, ready to tackle any situation.

But these were just elementary.

The true defense was the energy barrier that enveloped the entire headquarters, in the form of a transparent dome.

This dome was created by an advanced technology that belonged to Celestial Elysian Plane, courtesy of the great titan! It was strong enough to block high-stage Level VII Alpha!

What's more, this dome was capable of bursting with frightening offensive power in case of an attack!
