Collapse of the Energy Shield

"What is that odd-looking machine they are pulling?" The soldiers on top of the wall frowned in confusion. They had never seen anything like that before so they were all puzzled. 

"Stop dawdling and aim for that strange machine! It must be a secret weapon that we have never heard of!" Gunnar shouted at the soldiers.

'Just what is that thing?' Gunnar narrowed his eyes. He had a bad feeling when he saw the strange machine. 

At this moment, the odd-looking weapon was suddenly activated. The array formations inscribed on its body lit up and it soon produced an ear-splitting sound.

BOOOOM!!!

A violent explosion rang out as the defensive array formation on the wall was struck. It even caused the wall to tremble!
