As the magical barrier enveloping all of Ancient Rock City gradually dissipated, the spectators watching from afar were left dumbstruck, unable to utter a single word.
None of them could believe that such a powerful defensive magic formation had ultimately been completely shattered by three heavily wounded Holy Dragons.
"Damn it! How is this possible?!"
The Beast Emperor stared at the vanished magical barrier, his face an unspeakable shade of gloom.
The magical barrier was essentially the town's umbrella of protection. Without it, anyone could enter and leave freely, and wreak havoc upon the town.
Before the Beast Emperor could even react, Watercolor Rose raised her staff high.
"Advance with the light ballista carts—full assault on Ancient Rock City!"
The moment Watercolor Rose gave her order, two hundred light ballista carts began advancing toward Ancient Rock City.
Ancient Rock City had originally possessed defensive structures, but after falling under the control of the Evil God Temple, the evil demons and evil beasts had no idea how to operate them. They were nothing more than decoration. Without the defensive structures returning fire, the light ballista carts posed absolutely no threat.
Soon, Ancient Rock City entered the range of the light ballista carts.
Whoosh, whoosh, whoosh...
Two hundred explosive bolts shot out simultaneously, piercing through the towering city walls like a rainstorm and falling into the city. A series of explosions immediately echoed throughout Ancient Rock City.
In just a single volley, numerous buildings on the outskirts of Ancient Rock City were leveled to the ground...
"How dare they?!" The Beast Emperor watched as many of the houses meant for the evil demons' rest were destroyed, his heart dripping blood. He then directed all the evil beasts and evil demons to roar, "Charge! Destroy every last ballista cart for me!"
At this point, the Beast Emperor no longer cared about the city's defenses. His only thought was to destroy every light ballista cart belonging to the Zero Wing Guild.
The assault from the light ballista carts had also stirred the evil beasts and evil demons under NPC control into action, and they surged forward alongside those commanded by the Beast Emperor, charging straight toward Zero Wing's forces.
In an instant, the dark mass of evil beasts and evil demons surged toward Zero Wing's army like an incoming tide.
The Zero Wing members stationed in front of the ballista carts felt their scalps go numb.
However, Watercolor Rose remained unfazed. She immediately had someone activate a mobile defensive magic formation, and a magical barrier suddenly enveloped the entire army.
"Ballista carts—focus fire on these monsters! Everyone else, support the ballista carts and eliminate them! Feiying, you three hold those Legendary monsters in place!"
Once Watercolor Rose's commands rang out, the group quickly snapped into action, each person moving without hesitation.
Though the monsters were numerous and each boasted a high level, they had a defensive magic formation on their side. As long as the barrier held, the evil demons and evil beasts couldn't cause them any harm—let alone with two hundred light ballista carts pouring on the damage.
In moments, the ballista carts unleashed a relentless barrage. Bolt after bolt smashed into the clusters of evil beasts and evil demons, detonating on impact. Even Great Lord–rank evil demons and evil beasts were sent staggering backward by the blasts. Lord–rank ones struck directly were crippled on the spot, while Leader–rank demons and beasts were wiped out after just a few hits.
Behind the defensive barrier, the Zero Wing members poured out their own damage without restraint.
