"Fire!" A revolutionary knight shouted and pointed his sword at the Union army that was trying to enter the south gate.
Boulders, arrows, and giant arrows were shot at them, bombarding them without hesitation. However, the Mana barriers that the mages created were strong enough to deflect and stop them. No matter how many were thrown at them, the Union army didn't stop advancing.
The revolutionary mages couldn't penetrate the barriers as well since they weren't strong enough. They didn't want to waste their energy on something pointless, so they reserved their energy for the real fight later.
"Prepare the magic arrows!" The revolutionary knight ordered.
The revolutionary knights carried the ballista giant arrows that had been engraved with runes. Once they loaded all the ballistas, the knight signaled them to throw the giant arrows at the Union army. The arrows were infused with Mana, activating the magic formation, creating a piercing and wind-breaking spell.
