Chapter 252: Attacking from the Front, Harassing from the Rear, Coordinating Land and Air

Since breaking through the first line of defense at Mount Magitech Copper, the efficiency of the offensive had clearly dropped significantly.

At this time, they were already approaching the foot of Mount Magitech Copper. The more compact defensive formations brought denser enemy groups. Especially under the condition of needing to maintain a combat distance from the opponent, this made the battle of the Demon Lord's Castle legion particularly anxious and passive.

In the previous looser formations, they could rely on Priscilla, who was basically immune to the attacks of ordinary Mount Magitech Copper soldiers, to spew black flames and forcibly tear open a gap to surge in. But after entering the second line of defense, the hastily repaired city walls blocked the attack of the air force, and nearly a hundred specially-made ballista beds set up made it impossible for even Priscilla to charge recklessly, and she could only take a roundabout route.
