Booomm
The ground shook as a loud voice echoed in the area. A few broken pebbles weakly rolled on the ground and dust rose to the air.
"Seriously, that was only a mid-level monster!"
Someone grumbled with a half-astonished, half-scolding tone. Another voice responded to him in a relaxed way.
"Let him release all his anger on those monsters. If he doesn't, I'm scared he'll suddenly make our headquarters crumble to dust."
"Hmm..." The first one to talk groaned then mumbled in a low voice, "Poor monsters..."
BOMMMM
Another quake ran through the ground.
"But is it alright to leave him act like that?"
"Can you stop him?"
"No but..." Darren glanced at the area. "But I'm somehow worried about the natural ecosystems, you know."
"Pfft, what?"
Someone else arrived beside him and burst into laughter as soon as he heard Darren. Darren shot a cold glare at his teammate, Carlson.
