Demon Invasion

Three days later, Krune, Flita, and Wrister geared up for a battle early in the morning. They each donned armor made from the bones of Tier 4 Demons, armed to the teeth. Upon wearing the armor, Krune sighed, laughing as he shook his head, "I guess I was worried over nothing."

After all, the armor completely covered his body. Only the part of his eyes was visible to the onlookers. Well, that was also blocked by a layer of membrane that acted like glass. So, irrespective of his identity, no one would be able to recognize him under this armor. 

It seemed only those powerhouses at Tier 5 didn't wear armor. It was because armor was unnecessary to them. Not because they were strong, but because the Red Demons that arrived at the battlefield were usually young and way weaker than them. 

So, that was the reason they never wore armor. 

Before they departed, Krune looked at Hazak and said, "We'll be back soon. Protect this place until then."
