Though my troops are demons, it doesn't mean I'm a devil

Meanwhile, on the continent of Valoria, a battle was raging over a canyon.

A group of dark figures clashed with massive rock giants and flame creatures. 

Not far from the battlefield, at the edge of the canyon, stood two castles.

A slender man with a stern expression watched the distant battle, his face tense. 

Beside him stood a tall, burly man who looked simple and honest, lost in thought.

"These black creatures are like the undead; ordinary methods can't kill them," Cain observed. They were violent and frenzied, showing no signs of civilization. They weren't a race but rather puppets under someone's control.

So, they were likely the troops of a Lord. Otherwise, they wouldn't attack so madly upon sight.

"This is a troublesome problem. We were so close to reaching Monarch level, and now we encounter them," Earl said in a deep voice.
