The Arrogant Winged Demon

Reign quickly turned his body in the air and landed on the ground, sliding a couple of meters before charging at the demon who was laughing as he prepared another ball of demonic energy.

"Shall we play a game?" The demon asked Reign as he stared at him with a sneer.

"Will I run out of demonic energy first, or will you die from shielding your people?" The demon asked before launching the second ball at the player's army while Reign once again jumped up in the air to block it. The ball of demonic energy was made in such a way that it would explode upon the slightest touch, so even if Reign was to use a skill to destroy it, he would still be injured from the explosion.

As for the question the demon had asked, this entire place had been molded by the demons a long time ago and the demonic energy present was abundant, he could easily gather more of it from the dead demons as well, making it nearly impossible for him to run out of it.
