Garl did not use any special attacking means, and simply opened his mouth to suck everything in. In the blink of an eye, the Abyssal Demons were devoured. Only the few Abyssal Demons that were the furthest away from Garl were lucky enough to leave the devouring range of Garl. The other demons all fell into Garl's mouth.
After devouring the Abyssal Demons, Garl did not return to the team immediately. Instead, under Lin Li's command, he moved his bloated body and switched to another direction before opening his mouth and devouring the compact magic spells and formidable Abyssal Demons like he did before.
