The Hell Emperor's Divine Battle Array was an array formation Alex had learned back in Silvermoon city, near the Ancient Battlefield in the Northern Continent. He had bought it from an auction and had used it at the time to refine his intent.
At that time, he was certain that there would never come a time when he would ever use this technique, as he never saw himself being in an army, commanding soldiers of his own.
However, after he started gaining Blood Beasts, his mind slowly shifted back towards using this array.
Whenever he was on the islands to make pills or train, he would always remember to practice this array. It had only taken him a short time to realize just how valuable this thing was.
And today, he was going to show its value for everyone to see.
The hundred different beasts moved all at once in unison. They stuck to the array and flew into the sky to fight everyone that Alex had assigned as their enemy.
