A Surprise Attack from Underground

This is almost equivalent to one-third of the city's military strength. If it weren't for war behemoths like the Manticore, the results would have been even closer to the previous Battle of Azure Cloud Mountain.

With this in mind, Lin Xu used Yan Jingshu's senses to observe the Red-Robed Ghosts.

After absorbing a large amount of life force in a short period of time, the ghosts were unable to digest it. Their soul power trembled, and wisps of undigested essence were released.

"Once they go back and refine it once, the Red-Robed Ghosts will be firmly established at level 2 or above----"

Lin Xu directed the Red-Robed Ghost to explore further into the city while pondering the situation.

In addition to using the Precious Radiance Spirit-Tempering Cauldron to temper his own soul these days, he also tempers the Red-Robed Ghosts every day.

Being in a place as Spiritual Qi rich as Azure Cloud Mountain, the ghosts recovered very quickly. Including the "strongmen" that the Ghost Bride had recently recruited, most of the ghosts had already reached level 2 in just a few days.

Even without the Red-Robed Ghosts secretly plotting, the battle situation in the dungeon showed no signs of improvement.

Conversely, the large number of monsters that had been intercepted and killed earlier had greatly reduced the number of garrison troops in the city, making them even more helpless when facing the flying swords.

As their momentum waned, the constraints on the flying swords lessened, and their destruction of magical structures accelerated dramatically.

"Whoosh~"

With a flash of sword light, a corner of a magical building was severed, and fragments of the building crashed to the ground.

The Sword Qi swept across, disrupting the magic circuits buried deep underground.

"Boom~"

A few minutes later, the accumulated magic exploded, blasting a crater into the rock-like magic floor tiles.

The restrained magic burst forth from the destroyed magical channels, like blood spilling from a ruptured blood vessel.

Based on the explosion of the magic circuit, Lin Xu realized that Daoist Xuanzhen and the other two did not have a deep understanding of magic arrays, but that was enough.

The magic power constantly dissipating from the air became the source of the three Daoist priests' magical power.

As the destruction continued, more and more magical energy dissipated from the cave, to the point that the three Daoist priests, who originally only used flying swords, began to use them to cast spells.

The explosions of spells hastened the demise of the monster army.

Ah~

The roar of the giant city lord echoed deep within the dungeon. He had never imagined that he would not be defeated by a powerful enemy, but instead be betrayed by a hidden foe.

It unleashed its fury upon the three flying swords, unleashing a torrent of violent lightning within the cave, tearing through the darkness of the underground world.

The sword light flew away, traversing hundreds of meters in an instant. The violent and dense lightning roared, but was easily dodged by the flying sword.

Bolts of lightning lashed the ground, shattering the hard, magical tiles into fragments.

The dungeon lord quickly stopped its pointless venting and calmly watched the flying swords weave through the dark tunnels, spreading like a virus to other areas.

"Gather your forces, follow me out of the city!"

The giant left the Dungeon Heart, realizing it couldn't stop the flying swords from destroying the dungeon; it knew it only had one path left.

The underground city is vast; even if the three Daoist priests were allowed to wreak havoc, it would still take several months or even longer to completely destroy it.

But the giant city lord knew even better that the destruction of each district would delay the city's recovery.

At this point, the dungeon is like a giant that is constantly losing blood. If it doesn't launch a counterattack while it still has the strength, it will eventually become too weak to lift its sword.

Silently, the monsters that had been charging towards the flying sword disappeared into the darkness.

Apart from the occasional roar, the city returned to calm once again.

"The giants couldn't hold back any longer, a great battle is about to begin—" Lin Xu withdrew his gaze and looked expectantly at the entrance to the dungeon with the help of the Evil Eye's vision.

The three Daoist priests clearly noticed the anomaly, and soon, three flying swords passed through the passage and returned.

The once quiet military camp erupted in activity. Militiamen, Daoist soldiers, and Daoist priests were mixed together to form various battle teams, which were deployed around the entrance to the underground city.

Soon, the Daoist temple army formed a tight and complete defensive line centered on the entrance to the underground city.

The dungeon only had a couple hundred monsters left, but the Daoist temple camp had nearly 500 people, including Daoist soldiers and priests.

If you include the militia members who were used as cannon fodder, the total number easily exceeds 1,000.

In terms of military strength, the Daoist temple completely outclasses the underground city in both quality and quantity!

Relying on the formation that covers the entire military camp, the energy of the entire legion is connected and condensed into a whole.

A goblin stumbled out, only to be instantly bound by the power of the array, its entire body seemingly sinking into a quagmire, its every movement rendered in slow motion.

This minor role was handed over to the militia, who attacked with several steel forks, piercing the green-skinned dwarf.

Seemingly sensing the danger outside the passage, the underground city exit fell silent once more.

Just half an hour later, the ground collapsed suddenly more than 200 meters away from the military camp, revealing a dark passage.

Large numbers of monsters filed out and quickly assembled.

The anomaly on the ground was immediately noticed by the military camp, forcing the Daoist temple army, which had been in formation, to change direction and engage in battle with the monster army outside the camp.

With the help of the Evil Eye's vision, Lin Xu monitored the entire operation of the dungeon legion.

"No wonder they can build cities underground; the excavation speed is truly astonishing!"

Lin Xu looked at the collapsed passageway, where the little devils quickly widened the exit, allowing the monster army to pour out rapidly.

"Roar~"

The giant roared, its head emerging from the underground passage, glaring in the direction of the military camp, directing the monsters to quickly form ranks.

By the time the Daoist temple reacted, the monsters in the dungeon, led by the giant city lord, had already formed their battle formation.

"War is about to break out—wait!" Lin Xu was startled, keenly sensing the abnormal surge of Spiritual Qi around him. "Who is preparing a large-scale spell?!"

"Boom!"

The giant city lord raised his hands, and within seconds, dark clouds gathered in the sky, quickly forming a thundercloud with flashes of lightning, dispelling the darkness of the mist.

A bolt of lightning, like a dragon, ripped through space in an instant and struck the sturdy fence of the military camp.

It was like a bomb exploding, tearing a huge gash through the wooden fence and the soil on the ground.

A streak of lightning flashed across the ground, striking the unfortunate militiaman. He screamed and collapsed to the ground, his body reeking of burning.

Thunderclouds flashed, and bolts of lightning roared, spewing deadly thunder and fire towards the earth.

The violent lightning lashed the military camp, shattering the assembled Daoist soldiers one by one.

Whether they were weak militiamen, powerful Daoist soldiers, or Daoist priests who possessed magical powers, they were all torn to shreds in an instant by this cataclysmic lightning bombardment.

"This giant also knows high-level lightning magic—" Lin Xu frowned as he watched the giant city lord's berserk magic, which almost instantly enveloped a third of the camp in thunderclouds.

A magic array immediately rose in the military camp, forming an invisible barrier to resist the raging lightning.

However, the highly concentrated lightning repeatedly pierced through this magical barrier, bombarding the assembled Daoist soldiers.
