A moment later the origin of such noise revealed themselves. 25 G-rank monsters made up of frost goblins and artic horned rabbits with the goblins being the majority. Each of them had blood red eyes, protruding veins and saliva lingering around their lips as though starved crazy. 

Their expressions didn't change in the slightest at the sight of the tall ice and snow walls forcing them into a chokepoint. Nor did they quiver at the sight of dozens of much stronger and well prepared monsters lining those walls, staring down at them as though they were but mere prey. Their madness caused by the mana vein's corruption had completely clouded their judgements, overwriting their base instincts.
