Because of the charge from the Guard Knight Order, the mouse-ear clan soldiers on the frontline finally got a chance to breathe. They began retreating to reorganize the line, while some soldiers clad in full melee steel armor and carrying shields stepped forward.
The short-statured members of the mouse-ear clan formed a shield formation stretching for kilometers. Soon, with the sound of rolling wheels, large iron crossbows were transported to the mountaintop. Under the mouse-ear clan engineers' adjustments, these crossbows were aimed downward at the dense mechanical bodies below, while more than a dozen engineer soldiers began turning the winches to draw the strings.
A special Silver Iron Crossbow Arrow was loaded into the bowstring. Then the trigger was pulled, firing rapidly, raising a wave of autonomous units from the earth.
